Polygon 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 and Offramps guides.

Asset identifiers

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

Stablebond addresses

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 for the flow, and contact Etherfuse to confirm availability and gas requirements for Polygon.
