SpaceID Integration

SpaceID Integration

SpaceID is a multi-chain naming protocol supporting BNB Chain (.bnb), Arbitrum (.arb), Ethereum, and other networks. It positions itself as a universal Web3 name service with unified resolution SDK.

SDK Integration

import { SID, getSidAddress } from "@siddomains/sidjs";
import { ethers } from "ethers";

// BNB Chain
const bnbProvider = new ethers.JsonRpcProvider("https://bsc-dataseed.binance.org");
const sidBnb = new SID({ provider: bnbProvider, sidAddress: getSidAddress("56") });

// Arbitrum
const arbProvider = new ethers.JsonRpcProvider("https://arb1.arbitrum.io/rpc");
const sidArb = new SID({ provider: arbProvider, sidAddress: getSidAddress("42161") });

// Resolution
const address = await sidBnb.name("alice.bnb").getAddress();

// Reverse resolution
const name = await sidBnb.getName("0x742d35...");
// Returns { name: "alice.bnb" }

When to Choose SpaceID vs ENS

SpaceID makes sense if:

• Primary audience is BNB Chain users (PancakeSwap, Venus ecosystem)
• You need .arb name support for an Arbitrum-focused project
• Unified SDK for multiple networks simultaneously is required

ENS is preferable for: Ethereum focus, larger community, mature integration ecosystem.

Supported Networks

SpaceID integration in a dApp on BNB Chain or Arbitrum — 1-2 business days. Multi-chain resolution with multiple TLD support — 2-3 days.
