Returns the current inflation governor parameters.
These parameters define how inflation is distributed and how it changes over time.

Network.Solana.RPC.HTTP.Tokenomics
This module exposes Solana JSON-RPC methods for interacting with protocol-level tokenomics: inflation schedules, rewards, token supply, staking parameters, and validator vote accounts.
Useful for dashboards, analytics tools, staking services, or indexers.

getInflationGovernor
2 declarationsParameters defining the inflation configuration.
Constructors
InflationGovernorfoundation :: DoublePercentage of inflation allocated to the foundation.
foundationTerm :: DoubleDuration of the foundation pool inflation (in years).
initial :: DoubleInitial inflation rate at genesis (percentage).
taper :: DoubleRate per year at which inflation is lowered. (Rate reduction is derived using the target slot time in genesis config)
terminal :: DoubleTerminal inflation rate (percentage).
