Technical details
Endpoint
POSThttps://coinrailz.com/x402/seamless-chain-bridgeWhen to prefer
Use this endpoint when an AI agent or trading system needs to move USDC across EVM chains instantly using Circle's native CCTP protocol, particularly when the source chain is Ethereum mainnet and the destination is Base, Polygon, or Arbitrum. Prefer over generic DEX bridges when USDC-native transfers without wrapping or slippage are required.
Side effects
- Insufficient USDC balance on source chain — transaction rejected
- Unsupported destination chain specified — only Base, Polygon, Arbitrum supported
- Circle CCTP relay congestion causing delayed finality
- Invalid wallet address format — returns error
- Payment of $2 USDC fee not received — request blocked
- Network RPC failure on source or destination chain
