End User Accounts

Send transaction via end user Solana account

Changed on

Signs a transaction with the given end user Solana account and sends it to the indicated supported network. The API handles recent blockhash management and fee estimation, leaving the developer to provide only the minimal set of fields necessary to send the transaction. The unsigned transaction should be serialized into a byte array and then encoded as base64. Transaction types The following transaction types are supported:

  • Legacy transactions
  • Versioned transactions Instruction Batching To batch multiple operations, include multiple instructions within a single transaction. All instructions within a transaction are executed atomically - if any instruction fails, the entire transaction fails and is rolled back. Network Support The following Solana networks are supported:
  • solana - Solana Mainnet
  • solana-devnet - Solana Devnet The developer is responsible for ensuring that the unsigned transaction is valid, as the API will not validate the transaction.

Query parameters

projectIDstring
Example:8e03978e-40d5-43e8-bc93-6894a57f9324

The ID of the CDP Project. Required for end users authenticated using custom auth (i.e. a non-CDP JWT provider).

Headers

X-Wallet-Authstring

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.

X-Developer-Authstring

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.

Request body

addressstring required

The base58 encoded address of the Solana account belonging to the end user.

network'solana' | 'solana-devnet' required

The Solana network to send the transaction to.

walletSecretIdstring

Required when not using delegated signing. The ID of the Temporary Wallet Secret that was used to sign the X-Wallet-Auth Header.

transactionstring required

The base64 encoded transaction to sign and send. This transaction can contain multiple instructions for native Solana batching.

useCdpSponsorboolean

Whether transaction fees should be sponsored by CDP. When true, CDP sponsors the transaction fees on behalf of the end user. When false, the end user is responsible for paying the transaction fees.
