getInflationRate

getInflationRate returns the specific inflation values for the current epoch: a total rate plus the split between the portion paid to validators and the portion paid to the foundation. All three are annualized rates expressed as fractions — 0.0846 means an 8.46% annualized rate, not 0.0846%.

Use it to display current network inflation, estimate staking yield, or feed reward calculations. The values are epoch-scoped: the returned epoch field tells you which epoch they apply to, so clients that cache the result should re-fetch when the cluster advances to a new epoch.

This method takes no parameters and is inexpensive — it is a standard read method available on every tier. For the parameters that govern how these rates change over time, see getInflationGovernor; for per-account staking rewards, see getInflationReward.

This method takes no parameters. Send an empty positional array (params: []).

Response fields

Errors are returned in the standard JSON-RPC error envelope. See the shared errors reference for the full envelope shape and shared codes.

JavaScript (fetch)

const res = await fetch("https://api.triport.io/v1/sol", {
  method: "POST",
  headers: {
    "Authorization": `Bearer ${process.env.TRIPORT_API_KEY}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    jsonrpc: "2.0",
    id: 1,
    method: "getInflationRate",
    params: [],
  }),
});


const { result } = await res.json();
console.log(`Epoch ${result.epoch}: ${(result.total * 100).toFixed(2)}% total inflation`);

TypeScript SDK (@triport/sdk)

import { TriportClient } from "@triport/sdk";


const client = new TriportClient({ apiKey: process.env.TRIPORT_API_KEY });


const rate = await client.solana.getInflationRate();
console.log(`Epoch ${rate.epoch}: validator ${(rate.validator * 100).toFixed(2)}%`);

Python (triport-sdk)

import os
from triport import TriportClient


client = TriportClient(api_key=os.environ["TRIPORT_API_KEY"])


rate = client.solana.get_inflation_rate()
print(f"Epoch {rate['epoch']}: validator {rate['validator'] * 100:.2f}%")

• Annualized fractions. All three rates are fractions, not percentages. Multiply by 100 to display a percent (e.g. 0.0846 → 8.46%).
• Epoch-scoped. The returned epoch identifies which epoch the values apply to. Cache against this value and refresh when the cluster advances to a new epoch — pair with getEpochInfo to track the boundary.
• foundation may be 0. As foundation inflation tapers over time it can reach zero, in which case total equals validator.
• Related methods: getInflationGovernor for the governing parameters and getInflationReward for per-account staking rewards.
