Quick start

Connect with a Circle wallet or an external wallet.

Confirm the wallet is operating on Arc Testnet.

Choose USDC or EURC for payment, request, batch, swap, or private claim-code workflows.

Verify submitted transactions from the dashboard receipt and ArcScan links.

Send stablecoins, receive payment links, review balances, and export transaction receipts.

Build a payment request URL with recipient, amount, token, and optional memo fields.

Convert between supported stablecoin balances through Circle-powered swap routes.

Send one token to up to 500 recipients through SwiftBatch with fee routing.

Create private funded claim codes, manage payroll folders, and redeem receiver claims.

Start wallet session

{ "action": "challenge", "ownerWallet": "0x..." }

Security model

Wallets sign each payment, swap, and escrow action before funds move.

Private payment claim codes are scoped to the intended receiver wallet.

Recent private-send and payroll records are stored per active wallet profile.
