getInflationRate

getInflationRate reports how fast new SOL is being minted on Solana during the epoch in progress. Because Solana advances epochs roughly every couple of days, the inflation rate steps down over time along the network's tapering schedule, and this method gives you the value that applies right now. POST a JSON-RPC 2.0 request to https://solana.therpc.io/YOUR_API_KEY and the node returns the inflation rate for the current epoch as an object: total (the overall annualized inflation), validator (the portion that flows to stakers and validators), foundation (the portion reserved for the foundation), and epoch (the epoch number these figures describe).

Use cases

• Display the protocol-driven component of staking yield in a wallet or staking UI by surfacing validator, the share of SOL inflation that rewards delegators and validators.
• Break inflation into its validator versus foundation shares to show users exactly where newly minted SOL goes.
• Poll once per epoch and store total against epoch to chart how Solana's inflation rate steps down over time as the schedule tapers.

Parameters

This method takes no parameters. Pass an empty array [].

Errors & troubleshooting

Common pitfalls

• This is the network-wide protocol inflation rate, not any single delegator's APY. A real staking return depends on the total SOL staked across the network and your validator's commission, so combine this with getInflationReward and vote-account data before quoting a personal yield.
• The figures are already annualized but are tied to the current epoch; if you need a historical or forward-looking view, track the value per epoch and account for the taper rather than assuming today's number holds for the whole year.
