Code Examples

​

Basic Request

curl https://rpc.orbitflare.com -X POST -H "Content-Type: application/json" -d '{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "getInflationRate"
}'

​

Using web3.js

import { Connection } from '@solana/web3.js';

const connection = new Connection('https://rpc.orbitflare.com');

// Get current inflation rate
const inflationRate = await connection.getInflationRate();
console.log('Total inflation:', inflationRate.total);
console.log('Validator inflation:', inflationRate.validator);
console.log('Foundation inflation:', inflationRate.foundation);
console.log('Current epoch:', inflationRate.epoch);

// Calculate staking APY
async function calculateStakingAPY(totalStaked: number, totalSupply: number) {
  const inflationRate = await connection.getInflationRate();
  const validatorAPY = (inflationRate.validator * totalSupply) / totalStaked;
  
  return {
    validatorAPY,
    totalInflation: inflationRate.total,
    validatorInflation: inflationRate.validator,
    foundationInflation: inflationRate.foundation,
    epoch: inflationRate.epoch
  };
}

​

Notes

1. Returns the current inflation rate and its allocation
2. Total inflation is split between validators and foundation
3. Inflation rates are expressed as percentages
4. The response is immediate as it reads from the current state
5. Inflation rates can change between epochs

​

Best Practices

1. Use this method to understand current network inflation
2. Cache results when appropriate to reduce RPC load
3. Consider the impact of inflation on staking rewards
4. Monitor for changes in inflation rates
5. Use in conjunction with other inflation-related methods

Use Cases

1. Inflation Tracking

   Copy

   interface InflationHistory {
     epoch: number;
     total: number;
     validator: number;
     foundation: number;
     timestamp: number;
   }
   
   async function trackInflationHistory(
     epochs: number = 10
   ): Promise<InflationHistory[]> {
     const history: InflationHistory[] = [];
     const currentEpoch = (await connection.getEpochInfo()).epoch;
     
     for (let i = 0; i < epochs; i++) {
       const epoch = currentEpoch - i;
       const inflationRate = await connection.getInflationRate();
       
       history.push({
         epoch: inflationRate.epoch,
         total: inflationRate.total,
         validator: inflationRate.validator,
         foundation: inflationRate.foundation,
         timestamp: Date.now()
       });
       
       // Add delay to avoid rate limiting
       await new Promise(resolve => setTimeout(resolve, 1000));
     }
     
     return history;
   }
   

2. Staking Analysis

   Copy

   interface StakingMetrics {
     currentAPY: number;
     projectedAPY: number;
     totalStaked: number;
     totalSupply: number;
     inflationRate: number;
     validatorInflation: number;
   }
   
   async function analyzeStakingMetrics(): Promise<StakingMetrics> {
     const inflationRate = await connection.getInflationRate();
     const supply = await connection.getSupply();
     const voteAccounts = await connection.getVoteAccounts();
     
     const totalStaked = voteAccounts.current
       .concat(voteAccounts.delinquent)
       .reduce((sum, account) => sum + account.activatedStake, 0);
     
     const currentAPY = (inflationRate.validator * supply.value.total) / totalStaked;
     
     // Project future APY based on current trends
     const projectedAPY = currentAPY * 0.95; // Assuming 5% decrease
     
     return {
       currentAPY,
       projectedAPY,
       totalStaked,
       totalSupply: supply.value.total,
       inflationRate: inflationRate.total,
       validatorInflation: inflationRate.validator
     };
   }
   

3. Inflation Alerts

   Copy

   interface InflationAlert {
     type: 'high' | 'low' | 'change';
     message: string;
     currentRate: number;
     previousRate: number;
     difference: number;
   }
   
   class InflationMonitor {
     private previousRate: number | null = null;
     private threshold: number;
     
     constructor(threshold: number = 0.01) {
       this.threshold = threshold;
     }
     
     async checkInflation(): Promise<InflationAlert[]> {
       const inflationRate = await connection.getInflationRate();
       const alerts: InflationAlert[] = [];
       
       if (this.previousRate !== null) {
         const difference = Math.abs(inflationRate.total - this.previousRate);
         
         if (difference > this.threshold) {
           alerts.push({
             type: 'change',
             message: `Inflation rate changed by ${difference.toFixed(4)}`,
             currentRate: inflationRate.total,
             previousRate: this.previousRate,
             difference
           });
         }
       }
       
       // Check for unusually high or low rates
       if (inflationRate.total > 0.08) { // 8% threshold
         alerts.push({
           type: 'high',
           message: `Inflation rate is unusually high: ${inflationRate.total}`,
           currentRate: inflationRate.total,
           previousRate: this.previousRate || inflationRate.total,
           difference: 0
         });
       }
       
       if (inflationRate.total < 0.01) { // 1% threshold
         alerts.push({
           type: 'low',
           message: `Inflation rate is unusually low: ${inflationRate.total}`,
           currentRate: inflationRate.total,
           previousRate: this.previousRate || inflationRate.total,
           difference: 0
         });
       }
