# Polygon

> EVM asset identifiers and offramp setup on Polygon.

![Polygon](https://mintcdn.com/etherfuse/XRSchVFGUgreQatD/img/chains/polygon.svg?fit=max\&auto=format\&n=XRSchVFGUgreQatD\&q=85\&s=a36e37d0817ee9af4811faee50b50459)

Polygon is supported for onramps and offramps. Like Base, it's an EVM chain — assets are plain ERC-20 contracts. The end-to-end flows live in the [Onramps](https://docs.etherfuse.com/guides/testing-onramps.md) and [Offramps](https://docs.etherfuse.com/guides/testing-offramps.md) guides.

## Supported operations

| Operation | Supported |
| - | - |
| Onramp (fiat → token) | ✓ |
| Offramp (token → fiat) | ✓ |
| Swap (token → token) | ✗ — not yet on Polygon ([Stellar](https://docs.etherfuse.com/guides/chains/stellar.md) / [Solana](https://docs.etherfuse.com/guides/chains/solana.md) / [Monad](https://docs.etherfuse.com/guides/chains/monad.md) only) |

## Asset identifiers

Polygon assets are identified by the **raw token contract address only** — e.g. `0xcC77c598d42f2f78Beb42C91d12B9d4041a5cE29`.

> [!WARNING]
>
> **Do not prefix with a symbol.** Using `SYMBOL:0x...` (the Stellar-style format) on an EVM chain returns `UnsupportedBlockchain`. Pass just the `0x…` address from [`GET /ramp/assets?blockchain=polygon`](https://docs.etherfuse.com/api-reference/assets/list-assets).

## Stablebond addresses

Live token-contract addresses for every stablebond on Polygon, each linked to Polygonscan:

## Offramps

Polygon offramps follow the same EVM pattern as Base: selling an ERC-20 requires a one-time `approve()` before the offramp order. The ERC-20 approval endpoint and gasless offramps are rolling out per chain (currently Base) — see [Base → Offramps](https://docs.etherfuse.com/guides/chains/base.md#offramps-approve-the-token-first) for the flow, and contact Etherfuse to confirm availability and gas requirements for Polygon.
