eth_getTransactionCount - Gnosis RPC Method

Get the number of transactions sent from an address (nonce) on Gnosis. Essential for nonce management, transaction signing, and detecting stuck transactions.

Returns the number of transactions sent from an address on Gnosis, commonly known as the nonce. The nonce is required for every outbound transaction to ensure correct ordering and prevent replay attacks.

Why Gnosis? Build on the prediction market pioneer with $260M+ TVL and xDAI stablecoin-based gas fees with stablecoin gas fees for predictable costs, Shutter MEV protection, 150K+ Safe wallets, and Circles decentralized UBI protocol.

When to Use This Method

eth_getTransactionCount is essential for prediction market builders, DAO tooling developers, and teams building MEV-protected applications:

  • Transaction Signing — Get the correct nonce before building and signing a new transaction on Gnosis
  • Nonce Gap Detection — Compare latest and pending nonces to identify stuck or dropped transactions in the mempool
  • Account Activity Analysis — Track the total number of outgoing transactions from any address on prediction markets (largest by market cap), Safe wallet infrastructure, CoW Protocol DEX, and Gnosis Pay card integration
  • Batch Transaction Sequencing — Assign sequential nonces when submitting multiple transactions from the same address

Code Examples

Common Use Cases

1. Safe Transaction Sender with Nonce Management

Build a transaction sender that handles nonces correctly on Gnosis:

JavaScript
import { JsonRpcProvider, Wallet, parseEther } from 'ethers';

const provider = new JsonRpcProvider('https://api-gnosis-mainnet.n.dwellir.com/YOUR_API_KEY');

class TransactionSender {
  constructor(privateKey) {
    this.wallet = new Wallet(privateKey, provider);
    this.localNonce = null;
  }

  async getNextNonce() {
    // Get the pending nonce from the network
    const pendingNonce = await provider.getTransactionCount(
      this.wallet.address, 'pending'
    );

    // Use whichever is higher: local tracker or network pending
    if (this.localNonce === null || pendingNonce > this.localNonce) {
      this.localNonce = pendingNonce;
    }

    const nonce = this.localNonce;
    this.localNonce++;
    return nonce;
  }

  async sendTransaction(to, valueEth) {
    const nonce = await this.getNextNonce();

    const tx = await this.wallet.sendTransaction({
      to,
      value: parseEther(valueEth),
      nonce
    });

    console.log(`Sent tx ${tx.hash} with nonce ${nonce}`);
    return tx;
  }

  // Reset local nonce tracker (e.g., after errors)
  resetNonce() {
    this.localNonce = null;
  }
}

2. Stuck Transaction Detector

Detect and report stuck transactions by comparing nonces:

JavaScript
async function detectStuckTransactions(provider, address) {
  const confirmedNonce = await provider.getTransactionCount(address, 'latest');
  const pendingNonce = await provider.getTransactionCount(address, 'pending');

  const pendingCount = pendingNonce - confirmedNonce;

  if (pendingCount === 0) {
    console.log('No pending transactions');
    return { status: 'clear', pendingCount: 0 };
  }

  console.log(`${pendingCount} pending transaction(s) detected`);
  console.log(`Confirmed nonce: ${confirmedNonce}`);
  console.log(`Pending nonce: ${pendingNonce}`);
  console.log(`Stuck nonces: ${confirmedNonce} to ${pendingNonce - 1}`);

  return {
    status: 'stuck',
    pendingCount,
    confirmedNonce,
    pendingNonce,
    stuckNonces: Array.from(
      { length: pendingCount },
      (_, i) => confirmedNonce + i
    )
  };
}

// Usage
const result = await detectStuckTransactions(provider, '0xe91D153E0b41518A2Ce8Dd3D7944Fa863463a97d');
if (result.status === 'stuck') {
  console.log('Consider replacing transactions at nonces:', result.stuckNonces);
}

3. Batch Transaction Submitter

Submit multiple transactions in sequence with correct nonce ordering:

JavaScript
async function sendBatchTransactions(wallet, transactions) {
  const startNonce = await provider.getTransactionCount(
    wallet.address, 'pending'
  );

  console.log(`Sending ${transactions.length} transactions starting at nonce ${startNonce}`);

  const receipts = [];
  for (let i = 0; i < transactions.length; i++) {
    const nonce = startNonce + i;
    const tx = await wallet.sendTransaction({
      ...transactions[i],
      nonce
    });

    console.log(`Tx ${i + 1}/${transactions.length} sent: ${tx.hash} (nonce: ${nonce})`);
    receipts.push(tx);
  }

  // Wait for all to confirm
  const confirmed = await Promise.all(
    receipts.map(tx => tx.wait())
  );

  console.log(`All ${confirmed.length} transactions confirmed`);
  return confirmed;
}

// Usage
const transactions = [
  { to: '0xRecipient1...', value: parseEther('0.1') },
  { to: '0xRecipient2...', value: parseEther('0.2') },
  { to: '0xRecipient3...', value: parseEther('0.05') }
];

await sendBatchTransactions(wallet, transactions);

Error Handling

Common errors and solutions:

Error CodeDescriptionSolution
-32602Invalid paramsVerify the address is a valid 20-byte hex string and the block parameter is valid
-32603Internal errorRetry with exponential backoff
-32000Block not foundThe requested block may be pruned — use latest or pending
-32005Rate limit exceededImplement caching for nonce lookups
JavaScript
async function safeGetNonce(provider, address, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    try {
      return await provider.getTransactionCount(address, 'pending');
    } catch (error) {
      if (error.code === -32005) {
        await new Promise(r => setTimeout(r, Math.pow(2, i) * 1000));
        continue;
      }
      if (i === maxRetries - 1) throw error;
      await new Promise(r => setTimeout(r, Math.pow(2, i) * 1000));
    }
  }
}
