Pocket Network - Lightweight Tx Signing Example

Utilizing @pokt-foundation/* libraries may present challenges in native applications or require unnecessary audits due to it's dependencies.

This showcase demonstrates how to generate signed transaction data using lightweight dependencies:

• tweetnacl
• long
• protobufjs
• create-hash (optional, you can use Node.js crypto)

Submit txdata to /v1/client/rawtx

const POCKET_RPC_ENDPOINT = 'yourPocketRpcHost';

const { publicKey } = await nacl.sign.keyPair.fromSecretKey(
    Buffer.from(secretKeySample, "hex")
);

const address = getAddressFromPublicKey(publicKey);

if(!isAddressValid(receiverAddress)) {
    throw new Error('Invalid address');
}

const message = createSendMessage(address, receiverAddress, sendAmount);

const txdata = createTransaction(
    message,
    DEFAULT_BASE_FEE,
    "",
    secretKeySample
);

const res = fetch(`${POCKET_RPC_ENDPOINT}/v1/client/rawtx`, {
      method: 'POST',
      body: JSON.stringify(txdata),
});

const data = await res.json();

return data.txhash;
