onoma

a library for deterministically turning web3 addresses into names

Why?

Why is it called onoma?

Onomastics is the study of the history and origin of proper names, especially personal names.

(shoutout to 0xmts for the name)

Why did Metagame build this?

During Metagame's work on making transactions more human readable, we found ourselves often using the first 6 characters of an address as the wallet/contract's "name" when it didn't have an ENS associated with it. This is much harder to make an association with than a real name, so thought we'd give every wallet a name!

Installation

npm add onoma

yarn add onoma

Usage

import { addressToName, addressToNameObject } from 'onoma'

const address = '0x17A059B6B0C8af433032d554B0392995155452E6'

const name = addressToName(address)

console.log(name)
// Felicita Feeney

const nameObj = addressToNameObject(address)

console.log(nameObj)

/*
 {
    name: 'Felicita Feeney',
    prefix: 'Miss',
    firstName: 'Felicita',
    middleName: 'Micah',
    lastName: 'Feeney'
 }
*/

// You can also use abbreviated addresses with looseValidation
const abbreviatedAddress = '0x17A0...52E6'
const nameObjFromAbbr = addressToNameObject(abbreviatedAddress, true) // Pass true for looseValidation

console.log(nameObjFromAbbr)
// Returns a different result than the full address above, but a name nonetheless. Use only when you can't get the full address.

# Notes

Currently only supports 40 char hexidecimal addresses (EVM wallet addresses). Would be great if someone wanted to add support for other types of addresses :)

It can handle:
- Addresses with or without the `0x` prefix
- Both lowercase and uppercase addresses
- Abbreviated addresses in the format `0x1234...5678` when using `looseValidation`
