eth_hashrate - Tempo RPC Method

Returns the legacy eth_hashrate compatibility value on Tempo. Depending on the client behind the endpoint, this call may return a hex quantity like 0x0 or a method-not-found style error.

Why Tempo? Build on a payments-first EVM chain with deterministic settlement and stablecoin-native fees with no native gas token, fees denominated in supported USD stablecoins, and full EVM RPC compatibility.

Note: Treat eth_hashrate as a node-local mining metric and compatibility value. Public endpoints often report 0x0 or reject the method entirely, so it is not a reliable chain-health or consensus signal.

When to Use This MethodCopy Anchor Link

eth_hashrate is relevant for payment application developers, wallet teams, stablecoin issuers, and treasury automation builders:

• Node Diagnostics - Check whether the connected client reports a legacy hashrate metric
• Client Capability Checks - Distinguish between 0x0, unsupported-method, and method-not-found responses
• Dashboard Integration - Display the metric alongside other node status data when it is available

Best PracticesCopy Anchor Link

• Returns 0x0 on proof-of-stake chains (post-Merge) and most modern deployments
• Not relevant for most production environments; treat as informational only
• Do not rely on this method for chain health or consensus signals
• Use eth_syncing or eth_blockNumber for reliable node status monitoring

Common Use CasesCopy Anchor Link

1. Compatibility-Aware Status DashboardCopy Anchor Link

Display the reported compatibility value alongside other client status signals without assuming the method is always available:

async function getMiningStats(provider) {
  const blockNumber = await provider.getBlockNumber();
  let hashrate = null;
  let supported = true;

  try {
    hashrate = await provider.send('eth_hashrate', []);
  } catch (error) {
    supported = false;
  }

  return {
    supported,
    hashrate: hashrate ? parseInt(hashrate, 16) : null,
    currentBlock: blockNumber
  };
}

2. Capability CheckCopy Anchor Link

Check whether the connected client reports eth_hashrate at all:

async function getHashrateStatus(provider) {
  try {
    const hashrate = await provider.send('eth_hashrate', []);
    return { supported: true, raw: hashrate, isZero: hashrate === '0x0' };
  } catch (error) {
    return { supported: false, message: error.message };
  }
}

console.log(await getHashrateStatus(provider));
