tpu-client v1.0.4

TPU Client

Send transactions straight to the TPU Leaders.
This is a port of solana's rust tpu_client.
Sending transactions straight to TPU leaders can be helpful when the RPC you're using has a rate limit.

Building from Source

yarn install
yarn build

Installation via NPM

yarn add tpu-client

Usage

You can use TpuConnection just like a @solana/web3.js Connection object. In fact TpuConnection is just an extension of Connection.
The only thing which is different is that when you use sendTransaction and sendRawTransaction it sends the transaction to the tpu leader, instead of the rpcurl RPC.

const rpcurl = 'https://api.mainnet-beta.solana.com';
const tpuConnection = TpuConnection.load(rpcurl, { commitment: 'processed' });

(async () => {
    let tx = new Transaction();
    tx.add(instruction);
    tx.recentBlockhash = (await tpuConnection.getRecentBlockhash()).blockhash;
    tx.feePayer = wallet.payer
    tx = await wallet.signTransaction(tx);
    const signature = await tpuConnection.sendRawTransaction(tx.serialize());
})();
