### What SPACE ID provides

SPACE ID is the leading multi-chain Web3 Name Service. It supports `.bnb` on BNB Chain, `.eth` on Ethereum, `.arb` on Arbitrum, `.sol` on Solana, and 15+ more TLDs. The `@web3-name-sdk/core` SDK resolves names across all supported chains with a single API call.

### How Assetux uses it

**Forward resolution (type a name, get an address):**

    import { createWeb3Name } from '@web3-name-sdk/core';
    const w = createWeb3Name();
    const address = await w.getAddress('alice.bnb');
    // → 0xb5932a6b7d50a966aec6c74c97385412fb497540
    

This runs in the toAddress field — the user types a domain, the widget resolves it and validates the result against the selected destination chain type (EVM vs Solana).

**Reverse resolution (address → name):**

    const name = await w.getDomainName({
      address: evmAddress,
      queryChainIdList: [56, 1, 42161],
    });
    // → 'spaceid.bnb'
    

This runs on wallet connect — the connected wallet's domain (if any) shows as a chip beside the truncated address.

### Supported TLDs

`.bnb` · `.eth` · `.arb` · `.sol` · `.gno` · `.taiko` · `.mint` · `.sei` · `.lens` · and more.

### Why this matters

Web3 adoption slows down when users have to verify 42-character hex strings. SPACE ID names make sending and receiving crypto feel like sending an email. Assetux Exchange surfaces SPACE ID names natively in the swap UI — both in the sender display and as a valid recipient input.
