When to prefer

Use this endpoint when you need to deposit USDC to the PolyPay multisig wallet without requiring the sender to hold ETH for gas, leveraging EIP-3009 meta-transaction signatures. Prefer this over standard ERC-20 approve+transfer flows when the user cannot or prefers not to pay L1/L2 gas fees directly.

Side effects

Amount outside allowed range [1000000, 10000000000] — request rejected
Invalid or malformed EIP-3009 signature — authorization fails
Signature deadline expired — transferWithAuthorization nonce no longer valid
Incorrect from/to address in authorization — signature mismatch
USDC allowance or balance insufficient on-chain — transaction reverts
Network congestion causing delayed settlement
