Getting Address from Usernames

To retrieve an address from a username, we use the get_address_from_name function. The function interface is as follows:

#[view]
public fun get_address_from_name(name: String): Option<address>

InitiaJS

const { LCDClient, bcs } = require('@initia/initia.js');

const moduleAddress = '0x...';
const lcdUri = 'https://...';
const name = 'initia';
const lcd = new LCDClient(lcdUri);

lcd.move
  .view(
    moduleAddress,
    'usernames',
    'get_address_from_name',
    [],
    [bcs.string().serialize(name).toBase64()]
  )
  .then(console.log);

// Response:
// {
//   data: '"0x.."',
//   events: [],
//   gas_used: '5699'
// }

Getting Usernames from Address

To retrieve a username from an address, we use the get_name_from_address function.

#[view]
public fun get_name_from_address(addr: address): Option<String>

InitiaJS

const { LCDClient, bcs } = require('@initia/initia.js');

const moduleAddress = '0x...';
const lcdUri = 'https://...';
const address = "init1...";
const lcd = new LCDClient(lcdUri);

lcd.move
  .view(
    moduleAddress
    'usernames',
    'get_name_from_address',
    [],
    [
      bcs
        .address()
        .serialize(address)
        .toBase64(),
    ]
  )
  .then(console.log);

// Response:
// {
//   data: '"abc..."',
