5. Sign, Send, Track

Execute 4-step signing and broadcast with result tracking.

Prerequisites

Sign & Broadcast

Seal the deal! 📜 4 steps:

Wallet:

const wallet = new ProviderInternalBaseWallet(privateKey, senderAddress);

const wallet = new ProviderInternalBaseWallet(privateKey, senderAddress);

const wallet = new ProviderInternalBaseWallet(privateKey, senderAddress);

Provider/Signer:

const provider = new VeChainProvider(thor, wallet); 
const signer = await provider.getSigner(senderAddress);

const provider = new VeChainProvider(thor, wallet); 
const signer = await provider.getSigner(senderAddress);

const provider = new VeChainProvider(thor, wallet); 
const signer = await provider.getSigner(senderAddress);

Sign:

const rawSignedTx = await signer.signTransaction(txBody, privateKey);

const rawSignedTx = await signer.signTransaction(txBody, privateKey);

const rawSignedTx = await signer.signTransaction(txBody, privateKey);

Decode/Send:

const signedTx = Transaction.decode(HexUInt.of(rawSignedTx.bytes), true); 
const result = await thor.transactions.sendTransaction(signedTx); 
const receipt = await thor.transactions.waitForTransaction(result.id);

const signedTx = Transaction.decode(HexUInt.of(rawSignedTx.bytes), true); 
const result = await thor.transactions.sendTransaction(signedTx); 
const receipt = await thor.transactions.waitForTransaction(result.id);

const signedTx = Transaction.decode(HexUInt.of(rawSignedTx.bytes), true); 
const result = await thor.transactions.sendTransaction(signedTx); 
const receipt = await thor.transactions.waitForTransaction(result.id);

Boom—on-chain!

Common Pitfalls

Skip decode? SDK send fails; Check receipt.reverted! ignore reverted = bugs.
