How to set up the Domain SDK?

Before you can begin interacting with Cronos ID, you will need to obtain a reference to the CROID registry.

import CROID, { getCroidAddress } from '@cronosid/croidjs'



const croid = new CROID({ provider, croidAddress: getCroidAddress('25') }) // Cronos Mainnet Chain Id

croid.name('cronos.cro').getAddress() // 0x123

Resolving a name to a Cronos address

var address = await croid.name('cronos.cro').getAddress();

Reverse Resolution

While 'regular' resolution involves mapping from a name to an address, reverse resolution maps from an address back to a name. Cronos ID supports reverse resolution to allow applications to display Cronos ID names in place of hexadecimal addresses.

const address = '0x1234...';
let croidName = null;
({ name: croidName } = await croid.getName(address))
// Check to be sure the reverse record is correct. skip check if the name is null
if(croidName == null || address != await croid.name(croidName).getAddress()) {
  croidName = null;
}

Exports

default - CROID
getCroidAddress
getResolverContract
getCROIDContract
namehash
labelhash

CROID Interface

name(name: String) => Name

• Returns a Name Object, that allows you to make record queries.

resolver(address: CronosAddress) => Resolver

• Returns a Resolver Object, allowing you to query names from this specific resolver. Most useful when querying a different resolver that is different than is currently recorded on the registry. E.g. migrating to a new resolver

async getName(address: CronosAddress) => Promise<Name>

• Returns the reverse record for a particular Cronos address.

Name Interface

async getOwner() => Promise<CronosAddress>

• Returns the owner/controller for the current CROID name.

async getResolver() => Promise<CronosAddress>

• Returns the resolver for the current CROID name.

async getAddress(coinId: String) => Promise<CronosAddress>

• Returns the address for the current CROID name for the coinId provided.

async getContent() => Promise<ContentHash>

• Returns the contentHash for the current CROID name.

async getText(key: String) => Promise<String>

• Returns the text record for a given key for the current CROID name.

Resolver Interface

address

• Static property that returns current resolver address

name(name) => Name

• Returns a Name Object that hardcodes the resolver
