@requestnetwork/currency is a typescript library part of the Request Network protocol.
It is a collection of tools for the currencies and chains shared between the @requestnetwork packages.
npm install @requestnetwork/currencyimport { RequestLogicTypes } from '@requestnetwork/types';
import { Currency, Token } from '@requestnetwork/currency';
const decimals = new Currency({
type: RequestLogicTypes.CURRENCY.ETH,
value: 'ETH',
}).getDecimals();
console.log(decimals); // 18
const ETHHash = new Currency({
type: RequestLogicTypes.CURRENCY.ETH,
value: 'ETH',
}).getHash();
console.log(ETHHash); // 0xF5AF88e117747e87fC5929F2ff87221B1447652E
// Get currencies from their symbol
const ETHCurrency: RequestLogicTypes.ICurrency = Currency.from('ETH');
const FAUCurrency: RequestLogicTypes.ICurrency = Currency.from('DAI');
// Get currencies from their address
const DAICurrency: RequestLogicTypes.ICurrency = Currency.from(
'0x6B175474E89094C44Da98b954EedeAC495271d0F',
);
console.log(FAUCurrency.toString()); // FAU-rinkeby
console.log(DAICurrency.toString()); // DAI
// Get a token symbol from its address
const FAUToken = Token.from('0xFab46E002BbF0b4509813474841E0716E6730136');
console.log(FAUToken.symbol); // FAUPull requests are welcome. For major changes, please open an issue first to discuss what you would like to change. Read the contributing guide
Supported chains are listed in src/chains:
-
src/chains/btc/datafor BTC type chains -
src/chains/evm/datafor EVM type chains -
src/chains/near/datafor NEAR type chains
The chain names are subjective, but they are unique and uniform across all Request Network packages. They are formatted with the kebab-case naming convention.
In order to add a new chain, first create a file [nameOfTheChain].ts in the correct directory.
Its internal structure should conform with the corresponding type, respectively:
BtcChainEvmChainNearChain
These types are described in the index.ts file of each chain subdirectory.
Please add the testnet: true property for staging chains.
