Web3 Avatars Soft

A lightweight library that generates beautiful soft gradient avatars from Ethereum addresses. Each address produces a unique, visually pleasing gradient that can be used as an avatar or identity representation.

Demo

Run the demo locally: npm run dev

The demo page includes:

• Avatar generation from Ethereum addresses
• Random address generation
• Dark/light mode toggle to view avatars against different backgrounds

Installation

npm install web3-avatars-soft

Usage

import { generateAvatarGradientFromAddress, generateRandomAddress } from 'web3-avatars-soft';

// Generate CSS styles from an Ethereum address
const address = '0x742d35Cc6634C0532925a3b844Bc454e4438f44e';
const styles = generateAvatarGradientFromAddress(address);

// Apply the styles to an element
const avatarElement = document.getElementById('avatar');
avatarElement.style.backgroundImage = styles.backgroundImage;
avatarElement.style.filter = styles.filter;

// Or generate a random Ethereum address and use it
const randomAddress = generateRandomAddress();
const randomStyles = generateAvatarGradientFromAddress(randomAddress);

API

generateAvatarGradientFromAddress(address: string)

Generates CSS styles for creating a gradient avatar from an Ethereum address.

Parameters:

• address (string): An Ethereum address (0x followed by 40 hexadecimal characters)

Returns: An object containing:

• backgroundImage (string): CSS background-image property value with radial gradients
• filter (string): CSS filter property for enhanced visual effect

generateRandomAddress()

Generates a random Ethereum address.

Returns:

• A random Ethereum address string

How It Works

The library uses deterministic generation to create unique gradients based on the input Ethereum address:

1. It extracts color information from different parts of the address
2. Transforms these into aesthetically pleasing colors using the chroma-js library
3. Generates a complex CSS gradient using radial gradients at specific positions
4. Applies subtle filters to enhance the visual effect
