How this service works
A dollar account that puts your money on autopilot: earn yield, send money in seconds, and buy stocks from $1, all from one balance, with none of the crypto.
Output
Returns a JSON object with the bridge status (pending_attestation, attested, waiting_for_circle, submitted, or minted), the burn transaction hash on the source chain, the mint transaction hash on the destination chain (null if not yet minted), the amount of USDC received, the recipient's address on the destination chain, any referrer earnings, and a statusUrl to poll for updates.
Example use cases
Fund Arc wallet from Base
“I want to move 10 USDC from my Base wallet over to Arc so I can use it there — can you bridge it for me and let me know when it's done?”
Referral-earning bridge integration
“Bridge 25 USDC from Arc to Base and use my referrer address 0x1234567890abcdef1234567890abcdef12345678 so I earn part of the fee.”
Minimal cross-chain transfer
“Send the minimum — 1 USDC — from Base over to Arc as a test bridge transfer.”
Technical details
Endpoint
GEThttps://api.liquidagent.ai/v1/bridge?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to move USDC specifically between the Base and Arc chains in a single API call that handles burning, attesting, and minting. It is ideal for agents operating within the Liquid Agent ecosystem that already hold USDC on one of these two chains. Prefer this over generic bridge aggregators when you want a simple REST call with deterministic pricing and optional referral revenue sharing.
Side effects
- Amount below minimum of 1 USDC — rejected with validation error
- Invalid referrer EVM address format (not 0x + 40 hex chars) — schema validation failure
- Unsupported chain combination — only 'base' and 'arc' are valid for from/to
- Circle attestation delay — status remains pending_attestation or waiting_for_circle for extended period
- Insufficient USDC balance at payer address — transaction fails on source chain
- Network congestion causing slow mint confirmation — status stays 'submitted' for longer than expected
