Justlink at https://jlinkapp.com is a non-custodial interface to an on-chain USDC payment router on Arc. Justlink does not custody funds; payer and recipients settle directly via the smart contract.

Non-custodial

Justlink is a software interface. We do not hold, escrow, or guarantee USDC. Settlement occurs on-chain between the payer and the recipients configured in the payment session.

Smart contract risk

The payment contract has undergone an internal security review (see Security) but has not completed an independent third-party audit. Smart-contract, wallet, RPC, and user-error risks can result in loss of funds. Use at your own risk.

Payment limits

The following product limits apply. They are enforced by the app (not by the on-chain contract):

$5,000 USDC maximum per payment link
$25,000 USDC maximum cumulative per recipient wallet per day

Official Arc USDC only

Configure and use the official Arc USDC ERC-20. Unsupported or spoofed tokens are out of scope and may cause loss.
