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.

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.

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

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.

• Cross-chain swaps — swap tokens across Ethereum, Base, BSC, Arbitrum, Polygon, Optimism, Avalanche, Solana, and 20+ more networks via LiFi routing

• Any token — curated defaults plus community-listed tokens; unknown chains fall back to LiFi's full token catalog

• Buy with card — Visa/Mastercard onramp via Wert: pay USD, receive any supported token in your wallet

• Custom recipient — send swapped tokens to any address or Web3 Name domain, not just your own wallet

• URL deep links — pre-fill chain, token, amount, and recipient via query params

• SPACE ID — resolve .bnb, .eth, .arb, .sol domains in the recipient field; see your own domain next to your connected address

• List a token — submit any token for listing by paying a 10,000,000 ASX fee on Solana; verified on-chain automatically

• Non-custodial — swaps execute from user wallets directly; no funds held

Additional tokens can be listed by the community via the /listing page.
