getTokenSupply

Returns the total supply of an SPL Token mint. This includes the raw amount, decimal count, and human-readable formatted values. Knowing a token's total supply is fundamental for market cap calculations, tokenomics analysis, and understanding token inflation or deflation over time. This method queries a single mint address and returns its current total minted supply.

Parameters

#	Type	Required	Description
1	`string`	Yes	Base-58 encoded public key of the token mint
2	`object`	No	Configuration object

Configuration object fields:

Field	Type	Description
`commitment`	`string`	Commitment level: `processed`, `confirmed`, or `finalized`

Response

Returns an RpcResponse object:

Field	Type	Description
`context.slot`	`u64`	The slot at which the value was read
`value.amount`	`string`	Raw total supply as a string
`value.decimals`	`u8`	Number of decimals
`value.uiAmount`	`f64	null`
`value.uiAmountString`	`string`	Total supply as a string with decimal formatting
