In May 2026 OSL deployed the One-Coin / Multi-Chain project (see announcement), and this endpoint has been updated to support this.
A new string field networkhas been added that serves as the chain network identifier, e.g. ETHEREUM, TRON, etc.
- Request Parameters have been updated to include
networkas an optional field for clients who have already merged. - Response Parameters will now include

To identify which networks are available for a given currency, you can use the new Get Supported Transfer Network endpoint.
