A gasless swap lets you trade tokens without paying blockchain gas fees or even holding the native coin (ETH, BNB). Instead of broadcasting a transaction, you sign an 'intent' — a message describing the trade you want. Competing resolvers race to execute it for you, paying the gas themselves.
An off-chain signature (EIP-712) describing: what you sell, what you want, and your minimum acceptable amount. Signing is always free.
Professional market makers monitor the intent pool. They compete in an auction to fill your order — competition pushes the rate in your favor.
The winning resolver executes the swap on-chain, pays the gas, and delivers your tokens — all in one atomic transaction that reverts entirely if anything fails.
Because your trade isn't in the public mempool, sandwich bots can't front-run it. Gasless swaps are MEV-protected by design.
The resolver. They recover it from the spread inside the quoted rate. Nothing is hidden: the quote you accept is the amount you receive.
On 10FI: BSC and other EVM chains via intent-based settlement. Solana swaps cost ~$0.001 natively, so they're effectively gasless already.
