What is Zep Remit?

Traditional remittance companies like Western Union and MoneyGram charge 5 7% per transfer on a $500 remittance, that's $25 35 gone every single time. Zep Remit replaces that system with a direct, wallet to wallet USDC transfer over Arc Network, charging only 0.1% per transfer with gas costs of roughly $0.001.

Because Zep Remit is non custodial, we never hold or control your funds. Every transfer is a direct ERC 20 USDC token transfer from your wallet to the recipient's wallet executed on chain, visible on ArcScan, and settled in under one second.

Currently on Testnet. Zep Remit is live on Arc Testnet. You can test the full transfer flow with testnet USDC tokens at no cost. Mainnet launch is coming soon.

️ Double check all addresses. Blockchain transactions are final and irreversible. There is no chargebacks or recovery mechanism if you send to the wrong address. Always verify the recipient's address before confirming.

How it Works

Fee Structure

Zep Remit is designed to be the cheapest way to send money internationally. Our fee model is radically transparent no hidden spread, no exchange rate markup, no minimum transfer fees.

Zep Remit charges a flat 0.1% fee plus approximately $0.001 in Arc Network gas. On a $500 transfer, that's $0.50 total compared to $25 35 with traditional services.

Fee breakdown for a $500 transfer

Fee Type	Amount	Description
Zep Remit fee	$0.50 (0.1%)	Flat protocol fee on sent amount
Arc Network gas	~$0.001	On chain transaction cost, paid in USDC
FX spread	$0.00	None USDC transfers at par
Total on $500	≈ $0.50	Recipient receives $499.50

How it Works

Arc Settlement

Zep Remit is built on Arc Network a Layer 1 blockchain created by Circle (the company behind USDC). Arc is designed specifically for stablecoin native applications, making it the perfect infrastructure for global remittance.

Block explorer	testnet.arcscan.app	Verify any transaction
Native gas token	USDC (testnet)	No ETH required
Finality	< 1 second	Deterministic, not probabilistic
EVM compatible	Yes	All EVM wallets work

Why Arc for remittance?

Arc Network's key differentiator for remittance applications is that USDC is the native gas token. In most blockchains, you need ETH, BNB, or another volatile asset to pay gas. On Arc, you pay gas in USDC the same asset you're transferring. This means:

// Traditional EVM chain: user needs TWO tokens
balance_required = {
 ETH: "for gas (volatile price)",
 USDC: "for the actual transfer"
}

// Arc Network: user needs ONE token
balance_required = {
 USDC: "covers gas AND transfer"
}
 

This is crucial for remittance: a worker in Saudi Arabia doesn't need to understand crypto concepts like ETH gas. They just hold USDC and that's all they need to send money home.

Sub second finality explained

Arc Network uses a BFT (Byzantine Fault Tolerant) consensus mechanism that provides deterministic finality meaning transactions are final as soon as they're included in a block, not after multiple block confirmations. There's no "waiting for 12 confirmations" like on Ethereum. A Zep Remit transfer that leaves your wallet at 10:00:00 AM is in the recipient's wallet by 10:00:01 AM, with cryptographic certainty.

How it Works

Currency Support

Zep Remit uses USDC as the settlement layer for all transfers. This means all transfers move as USDC on chain, and conversion to/from local currencies happens at the edges when senders fund their wallets and when recipients cash out.

Settlement is always USDC. Regardless of the sender's funding currency (SAR, AED, etc.) or the recipient's payout currency (BDT, PKR, etc.), the on chain transfer is always native USDC on Arc. This eliminates volatility risk and simplifies the protocol.

Currencies

Sender Currencies

Sender currencies are the currencies that workers and senders can use to fund their Zep Remit transfers. All sender currencies are converted to USDC before being sent on chain.

Frequently Asked Questions

Everything you need to know about Zep Remit, Arc Network, and on chain remittance.

Is Zep Remit safe to use? ▾

Zep Remit is a non custodial application we never hold, touch, or have access to your funds. Your private keys stay in your wallet at all times. Transfers are standard ERC 20 USDC token transfers, which are the most battle tested transaction type in crypto history. The app is purely frontend there is no backend server storing your data.

Do I need to install a new wallet for Arc Network? ▾

No. Arc Network is EVM compatible, meaning any wallet that works with Ethereum (MetaMask, Rabby, Coinbase Wallet, etc.) works with Arc. You just need to add the Arc Testnet as a network Zep Remit does this automatically when you connect.

What is the minimum transfer amount? ▾

There is no enforced minimum on testnet. In practice, the ~$0.001 gas cost means transfers as small as $1 are still economically viable. Mainnet may introduce a soft minimum once live FX cash out is enabled.

Why does Zep Remit use USDC instead of a local stablecoin? ▾

USDC is a regulated, fully backed USD stablecoin issued by Circle the same company that built Arc Network. It's audited monthly, holds a 1:1 USD reserve, and is accepted across hundreds of DeFi protocols. Using USDC as the settlement layer means no price volatility during transit, predictable gas costs, and seamless integration with Arc's native infrastructure.

Can I send to someone who doesn't have a crypto wallet? ▾

Currently, the recipient needs an EVM wallet address to receive USDC. We're working on cash out integrations with local mobile money platforms (bKash in Bangladesh, UPI in India, GCash in Philippines, etc.) so recipients without wallets can receive funds via bank transfer or mobile money. This is a top roadmap priority.

What happens if I send to the wrong address? ▾

Blockchain transactions are irreversible by design. If you send USDC to the wrong address, there is no way to reverse the transaction. Always triple check the recipient's wallet address before confirming. Copy paste addresses rather than typing them manually.

How do I get testnet USDC? ▾

You can get testnet USDC from the Arc Network faucet at arc.network. Connect your wallet, request testnet USDC, and it will appear in your balance within seconds. Testnet tokens have no monetary value and are only for testing the Zep Remit flow.

When is mainnet launching? ▾

Mainnet launch timing depends on Arc Network's mainnet deployment schedule and our completion of cash out integrations. We're currently on testnet to gather user feedback, test the transfer flow, and refine the UX. Follow our updates for announcements.

Is Zep Remit open source? ▾

The frontend application is currently in private development while we finalize the protocol architecture. We plan to open source the code and publish smart contract audits before mainnet launch. The whitepaper documents the full technical design and fee model.

Do I need KYC to use Zep Remit? ▾

On testnet, no KYC is required just connect a wallet and you can transfer freely. For mainnet, regulatory requirements may apply depending on transfer size and jurisdiction. Our roadmap includes KYC free micro transfers under $200 for the initial launch, with KYC for larger amounts where legally required.

Zep Remit:
Borderless Money
for Everyone

A technical and economic overview of USDC based cross border remittances on Arc Network enabling near instant, near zero fee global money transfers for migrant workers and their families.

Read the Paper

01 Executive Summary

Executive Summary

Zep Remit is a non custodial, blockchain native remittance application built on Arc Network Circle's stablecoin first Layer 1 blockchain. Our protocol enables individuals to send USDC across borders to any EVM compatible wallet in under one second, with a flat 0.1% service fee and gas costs below $0.001 per transaction. This represents a 98% reduction in costs compared to the global average remittance fee of 6.2%, as reported by the World Bank in Q1 2026.

The global remittance market transferred approximately $860 billion in 2023 and is projected to exceed $1 trillion by 2028. Despite this scale, incumbent operators banks, money transfer operators, and mobile money platforms extract an average of $53 per $1,000 sent, with some corridors charging as high as 10 12%. This fee burden falls disproportionately on migrant workers in the Gulf, Southeast Asia, and Europe who support families in South Asia, Sub Saharan Africa, and Latin America.

Zep Remit eliminates this inefficiency by settling transfers on chain through the Arc Network's native USDC infrastructure. Funds arrive with deterministic finality in under one second. Senders need only a USDC funded EVM wallet; receivers get funds directly. Our current testnet deployment supports 6 sender corridors and 10+ receiver currencies. Mainnet launch is planned alongside Arc Network's production release in late 2026.

02 The Problem

The Problem

Remittances represent the single largest source of external financing for low and middle income countries, surpassing foreign direct investment and official development assistance combined. According to World Bank data, the 200 million migrant workers worldwide send money to approximately 800 million family members who depend on it for food, healthcare, education, and shelter.

"Remittance costs remain unacceptably high... meeting the Sustainable Development Goal target of 3% average cost is still far from reached." World Bank Remittance Prices Worldwide Report, Q1 2026

The problem is structural. Legacy remittance infrastructure relies on correspondent banking relationships, foreign exchange desks, settlement delays (T+1 to T+3), and compliance overhead all of which generate cost. These costs do not serve the sender or receiver; they serve intermediaries. The result is a systemic wealth transfer from the world's poorest workers to financial institutions.

World Bank Data Point

Sending $200 from the United States to Bangladesh costs an average of $12.40 a 6.2% fee. Western Union charges up to $15 18 for the same transfer. On an annual remittance of $6,000, families lose $370 $1,080 to fees alone.

Beyond fees, traditional remittances suffer from opacity (hidden FX markups), slow settlement (bank wires take 1 5 business days), geographic restrictions (many rural receivers have no bank branch access), and limited operating hours. Digital disruptors like Wise and Remitly have reduced some of these frictions but even they average 1 2.5% and still rely on underlying banking rails for final settlement.

Pain Point	Legacy Banks	Wise / Remitly	Zep Remit
Average fee	5 9%	1 2.5%	0.1%
Settlement time	1 5 days	Hours 1 day	< 1 second
Hidden FX markup	Yes (0.5 3%)	Minimal	None (USDC)
24/7 availability	No	Partial	Yes
Non custodial	No	No	Yes
Requires bank account	Yes	Yes	No (wallet only)

03 Our Solution

Our Solution

Zep Remit replaces legacy remittance infrastructure with a direct on chain transfer protocol. By using USDC a fully backed, regulated dollar stablecoin as the settlement asset on Arc Network, we eliminate every intermediary in the traditional flow: the correspondent bank, the FX desk, the compliance clearinghouse, and the local payout agent.

A sender connects their EVM compatible wallet, enters the recipient's wallet address and the amount in their local currency (SAR, AED, USD, GBP, EUR, or USDC), and taps send. The equivalent USDC is transferred to the recipient's wallet via a standard ERC 20 transfer on Arc Network. Settlement is deterministic and confirmed within 800 milliseconds.

The Core Proposition

No intermediaries. No forex spread. No waiting. Just USDC, moving at the speed of a blockchain confirmation, for a flat 0.1% fee plus sub cent Arc gas costs. The sender keeps their key; the receiver gets every cent intended.

Our approach is unique in the remittance space because it is entirely non custodial. Zep Remit never holds user funds, never stores private keys, and never intermediates the transfer. All interactions are client side wallet signatures. The only "fee" we collect is the 0.1% protocol fee, deducted from the USDC amount before it leaves the sender's wallet during the signing flow. Gas costs on Arc Network are paid separately in USDC at the network level and are typically less than $0.001.

On the receiver side, funds arrive instantly as USDC. For corridors where receivers need local currency (BDT, PKR, PHP, etc.), off ramp integrations with local exchanges and mobile money providers are planned for the mainnet phase, allowing cash out without requiring the receiver to manage USDC directly.

04 How It Works

How It Works

The Zep Remit transfer flow is designed to be as simple as any mobile payment app, while being powered entirely by on chain infrastructure. Below is a step by step breakdown of the complete send flow from the sender's perspective.

Connect Your Wallet

The sender visits Zep Remit and connects any EVM compatible wallet using the built in wallet picker. Supported wallets include MetaMask, Rabby, Phantom, Coinbase Wallet, Rainbow, Trust Wallet, Zerion, OKX Wallet, and 6+ more. The app automatically detects installed wallets and prompts to add Arc Testnet if needed.

Arc Network auto detection

Enter Amount & Currency

The sender selects their source currency (e.g. SAR, AED, USD) and enters the amount they wish to send. Zep Remit calculates the USDC equivalent in real time based on live exchange rate approximations. The sender also selects the receiver's local currency (BDT, PKR, INR, PHP, etc.) and sees the estimated local currency payout value. All fees are transparently shown before signing.

Real time FX conversion preview

Paste Recipient Address & Send

The sender pastes the recipient's Arc compatible wallet address (0x…). After reviewing the full breakdown amount, fee, estimated receipt they tap "Send Money" and sign the transaction in their wallet. Zep Remit calls a standard ERC 20 transfer() function on the USDC contract at 0x360000...0000 on Arc Network. No custom smart contracts are involved; no trust in Zep Remit code is required for the transfer itself.

ERC 20 USDC transfer · wallet signed only

Recipient Receives in < 1 Second

Once the transaction is signed and broadcast, Arc Network's consensus finalizes it with deterministic finality in under 800 milliseconds. The recipient's wallet balance updates immediately. A transaction hash is generated, visible on ArcScan (Arc's block explorer). The Zep Remit success modal displays the amount sent, amount received, fee paid, and a link to verify the transaction on chain.

Settled · verifiable · non reversible

️ Note on Testnet

All current transfers use testnet USDC on Arc Testnet no real money is moved. The experience is identical to the planned mainnet flow. Testnet USDC is freely available via the Arc Network faucet at arc.network.

05 The Arc Network

The Arc Network

Arc Network is a Layer 1 blockchain designed from the ground up around USDC. Built by Circle the issuer of USDC and co founder of the Centre Consortium Arc represents the first blockchain where USDC is the native gas token rather than an ERC 20 overlay. This design choice has profound implications for remittance applications.

Because USDC is native, there is no "bridging" step, no wrapped token, and no price discovery friction when transacting. A sender sends exactly what the receiver gets, denominated in a dollar pegged stablecoin with 1:1 reserve backing. Gas costs are also denominated and paid in USDC, removing the need for users to hold a separate "gas" cryptocurrency.

Property	Arc Network	Ethereum	Solana
Native gas token	USDC (stablecoin)	ETH (volatile)	SOL (volatile)
Block finality	< 1 second	~12 seconds	~0.4 seconds
EVM compatible	Yes	Native	No
USDC integration	Native layer 1	ERC 20 contract	SPL token
Avg. gas cost (USDC)	< $0.001	$0.50 $5.00	< $0.01
Chain ID (testnet)	`5042002`	`11155111` (Sepolia)	N/A

Arc's consensus mechanism achieves sub second deterministic finality a crucial property for remittances. Unlike probabilistic finality (where a transaction might be reorganized away), deterministic finality means once a transaction is confirmed, it is irreversible and settled. This removes reconciliation overhead, chargebacks, and the need for provisional holds.

Arc is EVM compatible, which means all existing Ethereum ecosystem tooling works natively: MetaMask, Ethers.js, Wagmi, Viem, Hardhat, and all major Web3 wallets integrate without modification. Zep Remit is built with vanilla Ethers.js v6, requiring zero custom infrastructure beyond pointing to Arc's RPC endpoint.

 // Arc Network connection config (Ethers.js v6)

 const ARC_RPC = 'https://rpc.testnet.arc.network';

 const ARC_CHAIN_ID = 5042002;

 const USDC_ADDRESS = '0x3600000000000000000000000000000000000000';

 // Standard ERC 20 transfer no custom contracts needed

 await usdcContract.transfer(recipient, amountInWei);

06 Fee Structure

Fee Structure

Zep Remit charges a single, flat 0.1% protocol fee on all transfers. There are no hidden foreign exchange markups (transfers are USDC to USDC), no withdrawal fees, no monthly subscription, and no corridor specific premiums. The only additional cost is Arc Network's gas fee, which is paid in USDC and is typically less than $0.001 per transaction.

The table below compares our total cost of sending $500 against the major players in the remittance market. All figures use publicly disclosed or verified transfer tests as of May 2026.

Western Union	~3%	~3.3%		~$31.50	Minutes days
Bank Wire (SWIFT)	$15 30 flat	2 4%	Correspondent fees	~$45	1 5 days

The compounding impact is significant. A migrant worker sending $500/month to their family pays approximately $378/year to Western Union money that never reaches the family. With Zep Remit, that cost drops to $6/year. Over a 10 year working abroad cycle, the savings exceed $3,700 enough to fund a child's university education in many receiver countries.

07 Currencies & Corridors

Supported Currencies & Corridors

Zep Remit currently supports 6 sender currencies and 11 receiver currencies on Arc Testnet, covering the world's highest volume remittance corridors. Gulf to South Asia represents approximately 40% of global remittance volume, making it our primary focus for the initial deployment. UK/EU corridors are in active development for mainnet.

Type	Currency	Country / Region	Status	1 Unit → USDC
Sender	SAR Saudi Riyal	Saudi Arabia	Live (Testnet)	≈ $0.267
Sender	AED UAE Dirham	United Arab Emirates	Live (Testnet)	≈ $0.272

Receiver	EGP Egyptian Pound	Egypt	Live	≈ 48.5 EGP
Receiver	NGN Nigerian Naira	Nigeria	Live	≈ 1,580 NGN
Receiver	MXN Mexican Peso	Mexico	Live	≈ 17.1 MXN

Rate conversions are currently approximated in the UI for display purposes only. Actual settlement is always in USDC 1 USDC = 1 USD by definition so the "local currency" display is informational. On chain feeds from Chainlink and Arc native oracle integrations are planned for the mainnet phase to provide live, verifiable exchange rate data.

08 Architecture

System Architecture

Zep Remit is architecturally minimal by design. There is no backend server, no database, no custodial component, and no proprietary smart contract. The entire application is a static HTML/CSS/JavaScript frontend that communicates directly with the Arc Network via a public RPC endpoint and the user's injected Web3 wallet.

The frontend communicates with Arc Network through the public testnet RPC endpoint (rpc.testnet.arc.network) using Ethers.js v6. Transaction history is available through ArcScan (testnet.arcscan.app). The UI is hosted as a static site it can run from any server, IPFS, or even be opened as a local HTML file.

For mainnet, the architecture will optionally include: (1) on chain oracle feeds for live FX rates, (2) a lightweight indexer for transaction history, and (3) off ramp adapters for local currency cash out. Even with these additions, the core transfer flow will remain entirely non custodial Zep Remit will never take custody of user funds at any point.

09 Security Model

Security Model

Zep Remit's security model is based on three principles: non custody, minimal surface area, and battle tested primitives. We deliberately do not introduce any novel cryptographic constructs, custom smart contracts, or proprietary backend infrastructure that could create new attack vectors.

Non Custodial

Private keys never leave the user's wallet. Zep Remit never has access to, stores, or processes private keys at any point.

ERC 20 Standard Only

All transfers use the standard USDC ERC 20 transfer() function the most audited contract type in the EVM ecosystem.

No Backend Attack Surface

There is no server, no database, no API. A compromised Zep Remit frontend cannot steal user funds only the user's wallet can sign transactions.

Fully Transparent

Every transfer is recorded on chain and verifiable by anyone on ArcScan. There are no off chain settlement tables or reconciliation databases.

️

Circle Backed USDC

USDC is issued by Circle with 1:1 reserve backing, attested monthly by Grant Thornton. There is no stablecoin depeg risk from Zep Remit's side.

Deterministic Finality

Arc's consensus provides deterministic (not probabilistic) finality. Confirmed transactions are irreversible, eliminating reorg based fraud vectors.

The primary security risk in any Web3 application is frontend compromise (XSS, supply chain attacks, or domain hijacking). We mitigate this by: (a) keeping the application as a single self contained HTML file with no third party runtime dependencies beyond Ethers.js loaded from a pinned CDN URL, (b) publishing source code openly for community review, and (c) planning to deploy to IPFS for censorship resistant, content addressed hosting on mainnet.

Users should always verify the transaction details in their wallet before signing. Zep Remit will never ask you to sign a setApprovalForAll(), permit(), or any transaction other than a direct ERC 20 transfer(). If you see otherwise, treat it as a phishing attempt.

11 Conclusion

Conclusion

The global remittance system is broken not because the technology to fix it didn't exist, but because the incumbents who profit from it had no incentive to change it. Zep Remit changes the calculus by removing all incumbents from the equation. On Arc Network, a USDC transfer is just a transfer: instant, transparent, verifiable, and cheap.

We believe that the 800 million family members who depend on remittances deserve better than losing 6% to intermediaries. A migrant worker in Riyadh should be able to tap their phone and have their entire paycheck arrive in Dhaka before they finish their lunch break. Not in 3 business days. Not with a $30 wire fee. Now. For $0.50.

Zep Remit is currently live on Arc Testnet. We invite developers, financial institutions, corridor partners, NGOs, and everyday users to test the protocol, review our code, and join us in building the remittance infrastructure the world actually needs. The technology is here. The network is ready. The only remaining step is adoption and we are just getting started.
