The Solana Token Balances APIs enable you to retrieve the balances of Solana addresses. This includes SPL tokens and the native SOL token of the network.

Denomination

  • ‘amount’ is denominated in the smallest indivisible unit of the token. For SOL, the smallest indivisible unit is lamports (10^-9 SOL). For SPL tokens, the smallest unit is defined by the token’s decimals configuration.
  • ‘decimals’ is the exponential value N that satisfies the equation amount * 10^-N = standard_denomination. The standard denomination is the most commonly used denomination for the token.
    • For native SOL, decimals is 9 (1 SOL = 10^9 lamports).
    • For SPL tokens, decimals is defined in the token’s mint configuration.
