The EVM Token Balances APIs enable you to retrieve the balances of EVM addresses. This includes tokens (i.e. ERC-20s) and the native gas token of the network.

Denomination

  • ‘amount’ is denominated in the smallest indivisible unit of the token. For ETH, the smallest indivisible unit is Wei (10^-18 ETH). For ERC-20s, the smallest unit is the unit returned from function totalSupply() public view returns (uint256).
  • ‘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.
    • In the case of the native gas token, decimals is defined via convention. As an example, for ETH of Ethereum mainnet, the standard denomination is 10^-18 the smallest denomination (Wei). As such, for ETH on Ethereum mainnet, decimals is 18.
    • In the case of ERC-20 tokens, decimals is defined via configuration. decimals will be the number returned by function decimals() public view returns (uint8) on the underlying token contract.
