OVERVIEW

What is Arfi?

A focused four-module DeFi front-end built entirely around Circle's stablecoin ecosystem. Every transaction — swaps and transfers included — is paid in USDC, no separate gas token needed.

Swap
Exchange stablecoins (USDC → EURC) via on-chain DEX with configurable slippage.
Bridge
Cross-chain USDC via Circle's native CCTP V2 — true 1:1 transfers.
Send
Direct ERC-20 transfers to any Arc Testnet wallet address.
Portfolio
Real-time balances, donut chart allocation, and total USD value.
BRIDGE — CIRCLE CCTP V2

Native burn-and-mint cross-chain

No wrapped tokens. No liquidity pool slippage. USDC burned on Arc, minted 1:1 on destination — across 5 testnet chains.
