Support
This library supports the following blockchains:
Constants
ZERO
The Address Zero.
CONSTANTS[blockchain].ZERO
e.g. CONSTANTS['ethereum'].ZERO // '0x0000000000000000000000000000000000000000'
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
The symbol of the native currency.
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
The written-out name of the blockchain.
CONSTANTS[blockchain].NAME
e.g. CONSTANTS['ethereum'].NAME // 'Ethereum'
