# Solutions for exchanges & onramps

> Let users withdraw to any chain with one address. Route onramped fiat to any destination chain or wallet. Eliminate withdrawal-stuck support tickets.

Exchanges and onramps face a structural problem: users want destinations on every chain, but you can't run withdrawal infrastructure for each one. Eco turns that into one integration that reaches anywhere.

## The pain you're solving

* Users want withdrawals to many destination chains, you'd need a separate integration per chain
* Withdrawal failures generate the highest-volume support tickets
* Onramp users want their fiat to land on the chain where they actually use it
* Your treasury sits on chains you don't actively operate on

## Patterns

### Fast deposits into Circle Gateway

Onramp partner sweeps customer USDC into Circle Gateway on Polygon for unified treasury management. Use Circle Gateway Deposits for 20–40 second settlement, gasless from the source chain.

### Withdrawal infra without N integrations

Instead of running per-chain withdrawal infrastructure, route every withdrawal through Routes. One integration, every supported chain.
