signAndSendSolanaTx()

signAndSendSolanaTx(params): Promise<string>

Defined in: utils/signAndSendSolanaTx.ts:38 

Builds a version 0 transaction with the given instructions, the signer as fee payer and the latest blockhash, then has the signer sign and send it. Use it inside an actionFunction: the returned signature is the txKey the Solana tracker follows.

Side effects: calls getLatestBlockhash through client.rpc and asks the wallet behind signer to sign and send the transaction.

Parameters

params

The client, the signer and the instructions.

client

SolanaClient

A Solana client, for example from createSolanaClientWithCache of @tuwaio/orbit-solana.

instruction

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

One instruction or an array of instructions.

signer

TransactionSendingSigner

A TransactionSendingSigner, such as the one from useWalletAccountTransactionSendingSigner of @solana/react; it pays the fee.

Returns

Promise<string>

The transaction signature, base58-encoded.

Throws

The error of the RPC call or of the signer (for example when the user rejects the transaction).

Example

const signature = await signAndSendSolanaTx({ client, signer, instruction: transferInstruction });
