Features

• .rsk domains:

  • availability and prices
  • registrations

• Manage domains:

  • Set subdomain owner
  • Get/set domain owner
  • Get/set domain resolver

• Manage resolution:

  • Get/set addr resolution

Usage

The library supports 3 modules:

• .rsk domains registrations using RSKRegistrar
• RNS domains admin using RNS
• Domain address resolution using AddrResolver

You will need to use this addresses to initialize the library:

| Contract name | RSK Mainnet | RSK Testnet | | - | - | - | | RNS Registry (rsnRegistryAddress) | 0xcb868aeabd31e2b66f74e9a55cf064abb31a4ad5 | 0x7d284aaac6e925aad802a53c0c69efe3764597b8 | | RIF Token ERC-677 ERC-20 (rifTokenAddress) | 0x2acc95758f8b5f583470ba265eb685a8f45fc9d5 | 0x19f64674d8a5b4e652319f5e239efd3bc969a1fe | | ERC-721 .rsk domains token (rskOwnerAddress) | 0x45d3e4fb311982a06ba52359d44cb4f5980e0ef1 | 0xca0a477e19bac7e0e172ccfd2e3c28a7200bdb71 | | .rsk domains registrar (fifsAddrRegistrarAddress) | 0xd9c79ced86ecf49f5e4a973594634c83197c35ab | 0x90734bd6bf96250a7b262e2bc34284b0d47c1e8d |

.rsk domain registrations

You can register .rsk domains paying with RIF Tokens. First, create the instance of RSKRegistrar

import { Signer } from 'ethers'
import { RSKRegistrar } from '@rsksmart/rns-sdk'

let signer: Signer
const rskRegistrar = new RSKRegistrar(rskOwnerAddress, fifsAddrRegistrarAddress, rifTokenAddress, signer)

Query price and availability

const label = 'taringa'

const available = await rskRegistrar.available(label)

const duration = BigNumber.from('1')

const price = await rskRegistrar.price(label, duration)

Register the domain

const { makeCommitmentTransaction, secret, canReveal } = await rskRegistrar.commitToRegister(label, testAccountAddress)

await makeCommitmentTransaction.wait()

// you need to wait at least for one minute, you can build
// your own polling strategy checking canReveal to ensure
// it is the correct time to submit the register tx
const commitmentReady = await canReveal()

if (!commitmentReady) throw

const registerTx = await rskRegistrar.register(
  label,
  testAccountAddress,
  secret,
  duration,
  price
)

await registerTx.wait()

Domain management

Create RNS instance

import { Signer } from 'ethers'
import { RNS } from '@rsksmart/rns-sdk'

let signer: Signer
const rns = new RNS(registryAddress, signer)

Owner

Get and set the controller of a domain you own

const domain = 'user1.taringa.rsk'
const newController = '0xb774...d771'

const tx = await rns.setOwner(domain, newController)
await tx.wait()

const controller = await rns.owner(domain)

Resolver

Get and set the resolver of a domain you own

const domain = 'user1.taringa.rsk'
const resolverAddr = '0xb774...d771'

const tx = await rns.setResolver(domain, resolverAddr)
await tx.wait()

const controller = await rns.resolver(domain)

Subdomains

Set the owner of a subdomain of a domain you own

const domain = 'taringa.rsk'
const subdomainLabel = 'user1'
const ownerAddress = '0x8c0f...1264'

const tx = await rns.setSubdmoainOwner(domain, subdomainLabel, ownerAddress)
await tx.wait()

Address resolution

Create AddrResolver instance

import { Signer } from 'ethers'
import { AddrResolver } from '@rsksmart/rns-sdk'

let signer: Signer
const addrResolver = new AddrResolver(registryAddress, signer)

Get and set the address of a domain or subdomain you own

const domain = 'user1.taringa.rsk'
const addr = '0xb774...d771'

const tx = await addrResolver.setAddr(domain, ownerAddress)
await tx.wait()

const addr = await addrResolver.addr(domain)

Branching model

• main has latest release. Merge into main will deploy to npm. Do merge commits.
• develop has latest approved PR. PRs need to pass ci and scan. Do squash & merge.
• Use branches pointing to develop to add new PRs.
• Do external PRs against latest commit in develop.
