15 chains, auto-detect, subtype identification, burn warnings.
A wallet address validator checks whether a crypto address is structurally correct before you send funds to it. A typo in a wallet address means lost money, since blockchains do not refund mis-sent transactions. This tool checks 15 major chains in parallel, identifies the chain from the address format alone, and flags burn / null addresses that would destroy the funds if you sent there.
Paste a Bitcoin, Ethereum, Solana, Cardano, Polkadot, or any of 11 other chain addresses, and the validator tells you what chain it's on, what subtype (legacy / SegWit / Taproot for BTC, EOA / contract for EVM), and whether the format is valid. Everything runs in your browser. Your address never leaves the page.
Unlimited validations, no signup. WalletValidator.io is free but pushes paid features and shows ads.
Most validators support 5-8. We cover Bitcoin, every EVM chain, Solana, Cardano, Polkadot, plus 10 more.
No "pick a chain" dropdown. Paste and read. WalletValidator.io makes you select first.
Wallet addresses sometimes reveal balance or identity. We never see them. No log, no telemetry, no API call.

Yes. Unlimited use, no signup, no daily cap. Validation runs entirely in your browser. WalletValidator.io shows ads and pushes paid features for chain-specific checks; we don't.
15 chains: Bitcoin (legacy / SegWit / Taproot), every EVM chain (Ethereum, BNB Smart Chain, Polygon, Avalanche, Fantom, Arbitrum, Optimism, Base -all share format), Solana, Cardano, Polkadot, XRP, Litecoin, Dogecoin, Bitcoin Cash, Tron, Stellar, Cosmos, NEAR, Aptos, Sui.
Yes. Paste any address and the validator runs format checks across all supported chains in parallel. The most likely match is the result, with secondary candidates listed for ambiguous cases (most addresses are unambiguous due to distinct prefixes and lengths).
Legacy P2PKH starts with 1, oldest format, biggest fees. P2SH starts with 3, multisig or SegWit-wrapped. Bech32 starts with bc1q (SegWit v0), 30% smaller fees. Bech32m starts with bc1p (Taproot), supports advanced scripts. The validator identifies each subtype.
No. The format checks run in your browser. Your wallet addresses, transaction destinations, and any test data stay on your laptop. There's no API call, no server log, no telemetry.
EIP-55 is the mixed-case checksum on Ethereum addresses. We detect mixed-case and flag it informationally, but full keccak256 verification needs a 30KB hash library we don't bundle for fast page load. Lowercase or all-uppercase addresses are checksum-neutral and validate cleanly.
Because every Ethereum-derived chain (Polygon, BNB Smart Chain, Avalanche, Arbitrum, Optimism, Base, Fantom, and 100+ others) uses the exact same address format. We report 'EVM' to remind you that an address valid on Ethereum is valid on Polygon, BNB, etc. Always confirm which chain you're sending on.
Format almost matches a chain but a length or character is off. Common causes: extra whitespace (paste glitch), missing or extra digit (typo), copy-paste truncation. Re-copy the address from the source.
Yes, but they share the same 0x + 64-char hex format. The validator flags this and asks you to confirm which network. Send confirmation: check the source application's dashboard for the explicit chain.
Yes. We flag the common burn addresses (0x0..0, 0x..dead, 1BitcoinEater...) so you don't accidentally send to one. We don't claim a comprehensive scam list, that would need a server-fetched feed and we don't run any servers.
15 chains, auto-detect, burn-address warnings, free unlimited. Paste any address.
