What is a fan-out swap?
A fan-out swap sends one input to many recipients — across different blockchains and tokens — in a single signature.
A normal swap turns token A into token B, for you. A fan-out swap turns one input into many payouts: to many wallets, on many chains, in many tokens — signed once.
The problem it solves
Paying several people across chains today is repetitive work. You bridge funds to the right network, swap into the token each person wants, switch networks, send — and repeat for every recipient. Classic multisend tools help, but only within one chain and one token at a time, with no bridging or swapping.
A fan-out swap collapses all of that into one action.
How a fan-out swap works
Fan-out swap vs. a normal swap vs. a multisend
| Normal swap | Multisend | Fan-out swap | |
|---|---|---|---|
| Recipients | one (you) | many | many |
| Chains at once | one | one | many |
| Token conversion | yes | no | yes |
| Signatures | one | one | one |
Where it works
Cherum runs a fan-out swap across 26 networks — EVM chains (Ethereum, Base, Arbitrum, Optimism, Polygon, BNB and more) plus non-EVM chains including TON, Tron (USDT), Solana and Bitcoin. Send from one chain and land on many; any input token can be delivered as any output token.
Is it safe?
Non-custodial. Your single signature hands the transfer to on-chain contracts — the service never holds, freezes or redirects funds. Those contracts are deployed and verified on every supported network, so anyone can read the exact code on each chain's explorer. Atomic per recipient: a leg that can't fill is refunded automatically, and delivered legs are unaffected.
Common use cases
- DAO & team payouts — contributor payments, grants, retro-drops across chains.
- Airdrops & rewards — deliver to a list of wallets, converting tokens on the way.
- Treasury moves — rebalance or distribute funds across several networks at once.
- Cross-chain transfers — send from TON, Tron, Solana or Bitcoin and land on EVM (or the reverse).
FAQ
Is a fan-out swap the same as a multisend?
No. A multisend sends one token to many recipients on a single chain. A fan-out swap adds cross-chain delivery and token conversion — recipients can be on different chains and receive different tokens, all from one signature.
Is it custodial?
On Cherum, no. Your signature hands the transfer to verified on-chain contracts; the service can't hold, freeze or redirect funds.
What if one recipient's leg fails?
Each recipient is a separate leg. A leg that can't fill is refunded to you automatically; delivered legs are unaffected.
What does it cost?
A small routing fee is included in the quote you see before signing. No subscriptions, no hidden spread.
