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 has been updated to include network as an optional field for clients who have already merged.

Note that the Response Parameters have not been changed; the return still contains WithdrawalResponse with transactionId or WithdrawalResult with message.

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