FAQ

Arrow DEX is a real, working cross-chain exchange — bridge USDC across Arc Testnet, Ethereum Sepolia, and Base Sepolia, swap USDC ⇄ EURC, provide liquidity, and stake ARROW-LP for real ARROW rewards. Every number on every page comes from an actual deployed contract, not a mock.

Arrow DEX uses Circle's Cross-Chain Transfer Protocol (CCTP) — a native burn-and-mint mechanism, not a wrapped-token bridge. USDC is burned on the source chain, Circle's attestation service verifies the burn, and the equivalent amount is minted natively on the destination chain. There is no synthetic or wrapped USDC at any point.

Approve authorizes the CCTP contract to move your USDC. Burn destroys it on the source chain and emits a message. Attestation is Circle validating that burn actually happened. Mint submits that attestation on the destination chain to release the equivalent USDC there.

Yes — real swaps between USDC and EURC through the ArrowSwap contract on Arc Testnet, priced by an on-chain constant-product formula with a 0.30% fee. cirBTC support is planned next.

Yes — the WUSDC/ARROW pool is a real constant-product AMM. Add or remove liquidity any time; every LP token represents a real, redeemable share of the pool's reserves.

Yes — stake ARROW-LP in the ArrowVault contract to earn real ARROW rewards, streamed continuously with no lock period. Withdraw or claim whenever you want.

No — everything runs on public testnets. Get free testnet USDC and gas from faucet.circle.com before you start.

Not yet — they follow well-understood, standard patterns (Uniswap V2-style AMM, Synthetix-style staking) but are unaudited testnet code. Treat them accordingly and never point real funds at them.
