Installation

npm install dotbit --save

QuickStart

Query users' addresses

// import { createInstance } from 'dotbit' // For ES Module
const { createInstance } = require('dotbit')
const dotbit = createInstance()

// Get all `eth` addresses of a .bit account
dotbit.addrs('imac.bit', '60').then(console.log)  // Result is the same as below, using coin_type
dotbit.addrs('imac.bit', 'eth').then(console.log) // It's recommended using coin_type as above, instead of symbol.

Developers are encouraged to use coin_type instead of plain symbol like 'eth' as coin_type is a more standard way to identify a chain/coin, and there will only be coin_type on chain in the future. What is coin_type

Query other different records:

// Get `twitter` account of a .bit account
dotbit.profiles('imac.bit', 'twitter').then(console.log)

// Get all `dwebs` of a .bit account
dotbit.dwebs('imac.bit').then(console.log)

// Get all .bit account records, please only use it when necessary.
dotbit.records('imac.bit').then(console.log)

Query .bit Alias(Reverse Record)

⚠️Notice: Only when .bit alias is set at https://app.did.id/alias by user, reverse record is valid.

const account = await dotbit.reverse({
  key: '0x1D643FAc9a463c9d544506006a6348c234dA485f',
  coin_type: '60', // See FAQ below to get the defination of coin_type
})
console.log(account.account) // jeffx.bit

Query the accounts that an owner address is holding

const accounts = await dotbit.accountsOfOwner({
    key: '0x1d643fac9a463c9d544506006a6348c234da485f',
    coin_type: '60', // See FAQ below to get the defination of coin_type
})

console.log(accounts[0].account) // thefirst💯registeredbydevteamtoensuredassuccessfullylaunched10.bit

Mint a SubDID in testnet:

Currently, SubDID is fully available in testnet, and need whitelist on mainnet. If you would like to distribute SubDIDs on mainnet, please email supermancy@did.id with a brief description of your project.

// import { createInstance, ProviderSigner, BitNetwork } from 'dotbit' // For ES Module
const { createInstance, ProviderSigner, BitNetwork } = require('dotbit')

const signer = new ProviderSigner(window.ethereum)
const dotbit = createInstance({
  network: BitNetwork.testnet,
  signer
})

const bitAccount = dotbit.account('imac.bit')

bitAccount.mintSubAccount({
  account: '001.imac.bit',
  keyInfo: {
    key: '0x...',
    coin_type: '60', // See FAQ below to get the defination of coin_type
  },
  registerYears: 1,
}).then(console.log)

FAQ

coin_type is the Coin Types defined in slip44 to distinguish different Coins/Chains.

For example, 60 is the coin_type of ETH, 0 is the coin_type of BTC, 714 is the coin_type of BNB, etc.

.bit use coin_type in multiple ways, here are 2 mainly usages:

• .bit use coin_type to identify each chain/coin in .bit records. In this situation, .bit support all coin_type defined in slip44.
• .bit use coin_type to identify different types of owner/manager key info. You can use ETH address(coin_type: 60) as your .bit owner and TRON address(coin_type: 195) as your manager. For all coin_type that .bit supported in key_info, please check const.ts
