Why Swapio

Built around what lands in your wallet — not what leaves it.

01 / ROUTING

Best-price routing, ranked by net output

Every quote from 40+ DEXs and bridges is scored on what actually arrives — after provider fees, gas on both chains and price impact. The top route is the one that pays you most.

02 / CUSTODY

Non-custodial by design

We return an unsigned transaction. Your wallet signs it, your keys never leave your device, and no Swapio contract ever holds a balance.

Questions

No. Swapio builds an unsigned transaction and returns it to your wallet. Funds move directly from your address into the provider’s route contracts and out to your destination address. There is no Swapio deposit address or pooled balance.

Every chain, every provider, one signature — and your keys never leave you.
