Interface TokenAmount

The 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. Not all tokens have a decimals field, as this function is optional in the ERC-20 specification. This field will be left empty if the underlying token contract doesn't implement decimals. Further, this endpoint will only populate this value for a small subset of whitelisted ERC-20 tokens at this time. We intend to improve coverage in the future.
