Cronos ID

Integrating using our SDK

How to access our domain SDK?

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

Resolving a name to a Cronos address

var address = await'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 {
croidName = null;


default - CROID

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

  • Static property that returns current resolver address
name(name) => Name
  • Returns a Name Object that hardcodes the resolver
