MAXINT

The number value (as a string) representing the maximum integer value (usually uint256).

CONSTANTS[blockchain].MAXINT

e.g. CONSTANTS['ethereum'].ZERO // '115792089237316195423570985008687907853269984665640564039457584007913129639935'

NATIVE

The address used to represent the native blockchain token alongside other token addresses.

CONSTANTS[blockchain].NATIVE

e.g. CONSTANTS['ethereum'].NATIVE // '0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE'

DECIMALS

The decimals for the native token of the individual blockchain.

CONSTANTS[blockchain].DECIMALS

e.g. CONSTANTS['ethereum'].DECIMALS // 18

WRAPPED

The address of the token contract providing a wrapped token of individual blockchain's native token.

CONSTANTS[blockchain].WRAPPED

e.g. CONSTANTS['ethereum'].WRAPPED // '0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2'

SYMBOL

CONSTANTS[blockchain].SYMBOL

e.g. CONSTANTS['ethereum'].SYMBOL // 'ETH'

CURRENCY

The written-out name of the native token on that blockchain.

CONSTANTS[blockchain].CURRENCY

e.g. CONSTANTS['ethereum'].CURRENCY // 'Ether'

NAME
