About this tool
Validate and identify crypto wallet addresses across 10 major blockchains.
Crypto Wallet Checker tests a wallet address against the address-format rules of ten blockchains — Bitcoin, Ethereum, Solana, Litecoin, Dogecoin, XRP, TRON, Cardano, Polkadot and BNB Smart Chain — and reports every chain and address type it validly matches. It is for anyone about to send funds who wants to confirm an address is well-formed and belongs to the network they think it does. Results name the specific format, such as Taproot (bc1p), SegWit (bc1q), P2SH (starts with 3), or an EVM 0x address with 40 hex characters.
Open Crypto Wallet Checker on AltFTool — it loads instantly in your browser.
Paste an address into the 'Paste any crypto wallet address here…' box on the 🔍 Checker tab — the character count sits in its corner — then press Check Address, or just hit Enter. Clear empties the box and the 📋 button pastes from your clipboard.
Read the 'N matching chains found' line and the cards beneath it: each gives the chain name, its symbol badge, the detected format — Legacy (P2PKH), SegWit (Bech32), Taproot (Bech32m), EIP-55 Checksum, Base58, SS58 and the rest — and a Copy button. An address that fits nothing shows 'No matching format found'.
Use 📋 Batch to check many addresses at once, one per line or comma-separated, with Check All returning a valid/invalid tally; 📖 Formats lists the accepted patterns for all 10 chains, and 🕐 History keeps your last 30 lookups until you press Clear History.
A Bitcoin address is reported as Legacy P2PKH, P2SH, SegWit Bech32 or Taproot Bech32m, so you can tell exactly which address type you are dealing with.
Formats overlap across networks — a 0x address is valid on both Ethereum and BNB Smart Chain — and all matching chains are listed instead of only the first guess.
Paste many addresses separated by newlines or commas to check them in one pass, and the last 30 checks stay listed so you can re-open any of them.
Ten: Bitcoin, Ethereum, Solana, Litecoin, Dogecoin, XRP, TRON, Cardano, Polkadot and BNB Smart Chain. Bitcoin, Litecoin and Cardano each have several recognised address types, so a single address can match a specific format within a chain.
No. The check is purely a format check against each chain's address pattern — it never queries a blockchain, so it cannot tell you whether an address has ever been used, holds a balance, or belongs to the person who sent it to you.
BNB Smart Chain is EVM-compatible and uses the identical address shape: `0x` followed by 40 hexadecimal characters. Format alone cannot separate the two, so you must confirm the intended network with whoever gave you the address.
Not cryptographically. A 0x address containing a mix of upper and lower case is labelled as checksummed and an all-lowercase one as plain hex, but the tool does not recompute the EIP-55 hash, so a mistyped character inside a mixed-case address can still pass.
