getInflationRate

Learn getInflationRate use cases, code examples, request parameters, response structure, and tips.

The getInflationRate RPC method returns a snapshot of inflation distribution for the current epoch, including how new SOL issuance is allocated between validators and the Solana Foundation. It provides a real-time view into the annualized inflation rate applied to token rewards and economic modeling.

✅ Common Use Cases

• Estimate Staking Returns View the current annualized inflation rate allocated to validators—useful for estimating staking APRs.

• Track Foundation Allocation Monitor the proportion of inflation being distributed to the Solana Foundation during the current epoch.

• Analyze Current Economic Metrics Fetch up-to-date inflation data to evaluate Solana’s token issuance behavior in the active epoch.

📦 Response Structure

The result field returns an object:

{
  "total": 0.065,
  "validator": 0.06,
  "foundation": 0.005,
  "epoch": 540
}

Field	Type	Description
total	f64	Total inflation rate for the current epoch (e.g., 0.065 = 6.5% annualized).
validator	f64	Portion of inflation allocated to validators (e.g., 0.06 = 6%).
foundation	f64	Portion of inflation allocated to the Solana Foundation (e.g., 0.005 = 0.5%).
epoch	u64	Epoch number to which the inflation rates apply.

Code Examples

Nodejs

const fetch = require('node-fetch');

async function getInflationRate(rpcUrl) {
  try {
    const response = await fetch(rpcUrl, {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({
        jsonrpc: '2.0',
        id: 1,
        method: 'getInflationRate'
      }),
    });

    const data = await response.json();
    
    // Print the exact full response
    console.log('Full RPC Response:');
    console.log(JSON.stringify(data, null, 2));
    
    return data;
  } catch (error) {
    console.error('Error getting health:', error.message);
    return null;
  }
}

// Example usage

🧠 Developer Tips

• Epoch-Specific Data These values are specific to the current epoch. To understand future trends or configurations, use getInflationGovernor.

• Annualized Rates Although values apply to the current epoch, they are expressed as annualized percentages, allowing for straightforward APR comparison.

• Rates Evolve Over Time The inflation rate tapers gradually based on the long-term monetary policy. While getInflationGovernor outlines the trajectory, getInflationRate shows the effective rate right now.

• Use in Wallets & Dashboards Integrate this endpoint to display real-time APR insights to delegators and validators.
