Gasless Transfers

Sending USDC normally requires holding the network's gas token (ETH on Arbitrum or Base) just to pay the fee. FurlPay removes that: you sign, FurlPay's sponsor submits and pays the gas.

How it works

USDC supports transferWithAuthorization (EIP-3009): instead of submitting a transaction yourself, you sign an authorization — a message saying "move N USDC from me to them, once, before this deadline." FurlPay's fee payer submits that authorization on-chain and pays the gas. The signature is single-use (a nonce burns with it), amount-exact, and recipient-exact — the sponsor cannot alter or reuse it.

What this means for you

• You can hold only USDC and still send it — no topping up ETH first.
• The quoted amount is what leaves your balance; the network fee is the sponsor's problem.
• Your key signs a message, not a transaction — the same fingerprint confirmation as any other send.

Supported networks

Gasless sending works on the EVM networks where FurlPay runs a sponsor, Arbitrum first. The send screen shows a "no network fee" label when the rail applies; on networks without a sponsor, the standard flow applies instead.
