signAndSendSolanaTx()

signAndSendSolanaTx(params): Promise<string>

Defined in: packages/pulsar-solana/src/utils/signAndSendSolanaTx.ts:34 

Creates, signs, and sends a Solana transaction with one or more instructions.

This async function orchestrates the common flow for broadcasting a transaction:

1. Fetches the latest blockhash from the RPC.
2. Creates a versioned transaction (v0).
3. Signs the transaction with the provided signer.
4. Sends the transaction to the network.
5. Decodes and returns the resulting transaction signature.

Parameters

params

The parameters for signing and sending the transaction.

client

SolanaClient

The Solana client instance for RPC communication.

instruction

Instruction<string, readonly (AccountLookupMeta<string, string> | AccountMeta<string>)[]> | Instruction<string, readonly (AccountLookupMeta<string, string> | AccountMeta<string>)[]>[]

A single instruction or an array of instructions to include in the transaction.

signer

TransactionSendingSigner

The signer (e.g., a wallet) responsible for signing the transaction.

Returns

Promise<string>

A promise that resolves to the transaction signature.

Throws

Will throw an error if any of the async operations (fetching blockhash, signing, sending) fail.

Example

const signature = await signAndSendSolanaTx({
client: mySolanaClient,
signer: wallet,
instruction: myTransferInstruction,
});
console.log('Transaction sent with signature:', signature);
