Environments​

Yellow Network operates two separate environments:

EnvironmentPurposeURL
SandboxDevelopment and testingwss://clearnet-sandbox.yellow.com/ws
ProductionLive operations with real assetswss://clearnet.yellow.com/ws
Environment Separation
  • Sandbox uses testnet blockchains and test tokens (e.g., ytest.usd)
  • Production uses mainnet blockchains and real assets (e.g., usdc)
  • Assets and blockchains from one environment cannot be used in the other

Quick Code Reference​

Connecting to the Right Environment​

import { Client } from "yellow-ts";

// Sandbox (for testing with ytest.usd)
const sandboxClient = new Client({
    url: 'wss://clearnet-sandbox.yellow.com/ws',
});

// Production (for real assets like usdc)
const productionClient = new Client({
    url: 'wss://clearnet.yellow.com/ws',
});

Using the Correct Asset​

// Sandbox environment
const sandboxAllocations = [
    { participant: address1, asset: 'ytest.usd', amount: '100.0' },
    { participant: address2, asset: 'ytest.usd', amount: '0.0' }
];

// Production environment
const productionAllocations = [
    { participant: address1, asset: 'usdc', amount: '100.0' },
    { participant: address2, asset: 'usdc', amount: '0.0' }
];
