Solana Accounts

Sign transaction

Changed on Oct 6, 2026

Signs a transaction with the given Solana account. The unsigned transaction should be serialized into a byte array and then encoded as base64.

Transaction types

The following transaction types are supported:

The developer is responsible for ensuring that the unsigned transaction is valid, as the API will not validate the transaction.

post/v2/solana/accounts/{address}/sign/transaction

Request

Base URL: https://api.cdp.coinbase.com/platform
URL: https://api.cdp.coinbase.com/platform/v2/solana/accounts/{address}/sign/transaction
Auth: HTTP bearer

Path parameters

addressstring required

The base58 encoded address of the Solana account.

Headers

X-Wallet-Authstring required

A JWT signed using your Wallet Secret, encoded in base64. Refer to the Generate Wallet Token section of our Authentication docs for more details on how to generate your Wallet Token.

X-Idempotency-Keystring

An optional string request header for making requests safely retryable. When included, duplicate requests with the same key will return identical responses. Refer to our Idempotency docs for more information on using idempotency keys.

Request body

network'solana' | 'solana-devnet'

The Solana network the transaction targets. Required when using versioned transactions that reference address lookup tables, since resolving those tables requires querying a specific network. Optional otherwise.

transactionstring required

The base64 encoded transaction to sign.

Example request

{
  "network": "solana-devnet",
  "transaction": "AQABAgIAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAQABAQECAwQFBgcICQoLDA0ODxAREhMUFRYXGBkaGxwdHh8CBgMBAQAAAAIBAwQAAAAABgIAAAAAAAYDBQEBAAAGBAgAAAAABgUAAAAA6AMAAAAAAAAGBgUBAQEBBgcEAQAAAAYICgMBAQIDBgkCBgAAAAYKAwABAQEGCwMGAQEBBgwDAAABAQAAAAA="
}

Response

Successfully signed transaction.

signedTransactionstring required

The base64 encoded signed transaction.

Example response

{
  "signedTransaction": "AQACAdSOvpk0UJXs/rQRXYKSI9hcR0bkGp24qGv6t0/M1XjcQpHf6AHwLcPjEtKQI7p/U0Zo98lnJ5/PZMfVq/0BAgIAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAQABAQECAwQFBgcICQoLDA0ODxAREhMUFRYXGBkaGxwdHh8CBgMBAQAAAAIBAwQAAAAABgIAAAAAAAYDBQEBAAAGBAgAAAAABgUAAAAA6AMAAAAAAAAGBgUBAQEBBgcEAQAAAAYICgMBAQIDBgkCBgAAAAYKAwABAQEGCwMGAQEBBgwDAAABAQAAAAA="
