What SPACE ID providesSPACE 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 itForward 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 mattersWeb3 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.FeaturesCross-chain swaps — swap tokens across Ethereum, Base, BSC, Arbitrum, Polygon, Optimism, Avalanche, Solana, and 20+ more networks via LiFi routingAny token — curated defaults plus community-listed tokens; unknown chains fall back to LiFi's full token catalogBuy with card — Visa/Mastercard onramp via Wert: pay USD, receive any supported token in your walletCustom recipient — send swapped tokens to any address or Web3 Name domain, not just your own walletURL deep links — pre-fill chain, token, amount, and recipient via query paramsSPACE ID — resolve .bnb, .eth, .arb, .sol domains in the recipient field; see your own domain next to your connected addressList a token — submit any token for listing by paying a 10,000,000 ASX fee on Solana; verified on-chain automaticallyNon-custodial — swaps execute from user wallets directly; no funds heldSupported Networks & TokensNetworkTokensEthereumETH, USDC, USDT, aaaBTCBaseETH, USDC, aaaBTCBSCBNB, USDC, USDT, aaaBTCArbitrumETH, USDC, USDT, aaaBTCPolygonPOL, USDC, USDTOptimismETH, USDC, USDTAvalancheAVAX, USDC, USDTSolanaSOL, USDC, USDT, ASX, HOTPOTzkSync EraETH, USDC, USDTLineaETH, USDCScrollETH, USDC, USDTBlastETH, USDBMantleMNT, USDC, USDTGnosisxDAI, USDC, USDTWorld ChainETH, USDC, ASXCeloCELO, USDC, USDTModeETH, USDC, USDTTaikoETH, USDC, USDTSonicS, USDCSei EVMSEI, USDCopBNBBNB, USDC Additional tokens can be listed by the community via the /listing page.
