# 1:1 stablecoin swaps

> Discuss eligible stablecoin pairs, fees, and access for 1:1 stablecoin swaps with Eco.

**1:1 stablecoin swaps** are closed access. [Contact Eco](mailto:contact@eco.com) to confirm eligible pairs, fees, and integration requirements.

For any transfer, use the amount and fee fields in the quote to determine what the recipient can receive. Holding the same stablecoin on both chains does not by itself imply a fee-free transfer or a 1:1 output amount.

## Before integrating

Confirm the following with Eco:

* Which source and destination token pairs are eligible.
* Whether fees are deducted from the transferred amount or sponsored separately.
* Which API and funding flow your integration should use.

## Next steps

Read [Routes](/routes/overview) for the public transfer flow and [Supported chains and tokens](/resources/supported-chains-tokens) for discovery endpoints.
