Solana Signers

Transaction signers for Solana Node.js/CLI integrations.

Supported signers for:

• Solana keypair via tweetnacl
• Ledger hardware wallets via @ledgerhq/hw-app-solana
• Trezor hardware wallets via @trezor/connect

Install with npm:

npm install --save @rathe/solana-signers

Examples

Signing with a keypair:

import {
  Connection,
  Keypair,
  SystemProgram,
  LAMPORTS_PER_SOL,
  Transaction
} from "@solana/web3.js";
import { NaclTransactionSigner } from "@rathe/solana-signers";

const rpcUrl = "YOUR_RPC_URL";
const connection = new Connection(rpcUrl, "confirmed");

const keypair = Keypair.generate();
const signer = new NaclTransactionSigner(keypair);

const fromAddress = signer.publicKey;
const toKeypair = Keypair.generate();
const lamportsToSend = 1_000_000;

const transferTransaction = new Transaction().add(
  SystemProgram.transfer({
    fromPubkey: fromAddress,
    toPubkey: toKeypair.publicKey,
    lamports: lamportsToSend
  })
);

await signer.signTransaction(transferTransaction);
const signature = await connection.sendRawTransaction(transferTransaction.serialize());

const result = await connection.confirmTransaction(signature);
if (result.value.err != null) {
  throw result.value.err;
} else {
  console.log("Transaction confirmed: %o", signature);
}

Signing with a Ledger hardware wallet:

import {
  Connection,
  Keypair,
  SystemProgram,
  LAMPORTS_PER_SOL,
  Transaction
} from "@solana/web3.js";
import { LedgerTransactionSigner } from "@rathe/solana-signers";

const rpcUrl = "YOUR_RPC_URL";
const connection = new Connection(rpcUrl, "confirmed");

const bip32Path = "LEDGER_BIP32_PATH"; // Can be found in the Ledger Wallet app
const signer = await LedgerTransactionSigner.create(bip32Path);

const fromAddress = signer.publicKey;
const toKeypair = Keypair.generate();
const lamportsToSend = 1_000_000;

const transferTransaction = new Transaction().add(
  SystemProgram.transfer({
    fromPubkey: fromAddress,
    toPubkey: toKeypair.publicKey,
    lamports: lamportsToSend
  })
);

await signer.signTransaction(transferTransaction);
const signature = await connection.sendRawTransaction(transferTransaction.serialize());

const result = await connection.confirmTransaction(signature);
if (result.value.err != null) {
  throw result.value.err;
} else {
  console.log("Transaction confirmed: %o", signature);
}

Signing with a Trezor hardware wallet:

import {
  Connection,
  Keypair,
  SystemProgram,
  LAMPORTS_PER_SOL,
  Transaction
} from "@solana/web3.js";
import { TrezorTransactionSigner } from "@rathe/solana-signers";

const rpcUrl = "YOUR_RPC_URL";
const connection = new Connection(rpcUrl, "confirmed");

const path = "TREZOR_WALLET_PATH"; // Can be found in the Trezor Suite app
const signer = await TrezorTransactionSigner.create({ path });

const fromAddress = signer.publicKey;
const toKeypair = Keypair.generate();
const lamportsToSend = 1_000_000;

const transferTransaction = new Transaction().add(
  SystemProgram.transfer({
    fromPubkey: fromAddress,
    toPubkey: toKeypair.publicKey,
    lamports: lamportsToSend
  })
);

await signer.signTransaction(transferTransaction);
const signature = await connection.sendRawTransaction(transferTransaction.serialize());

const result = await connection.confirmTransaction(signature);
if (result.value.err != null) {
  throw result.value.err;
} else {
  console.log("Transaction confirmed: %o", signature);
}
