Public Key Toolkit — X/Y, HASH160 & Address

Pick a chain, then paste a public key (or a HASH160 / address). The toolkit derives the public-key X & Y coordinates and the correct address(es) for that chain — legacy, SegWit & more for Bitcoin, Litecoin, Dogecoin, Bitcoin Cash & Zcash; EIP-55 addresses for Ethereum & every EVM chain; plus Tron, XRP, Solana, Sui & TON. For a Bitcoin address it can also recover the public key by scanning its spending transactions. Everything runs in your browser.

Accepts a compressed (66 hex) or uncompressed (130 hex) public key, a 40-hex HASH160, or an address. For a Bitcoin address, the public key is recovered by scanning its transactions for the key it revealed on-chain.

Recover public key from an address (scans transactions)

Transactions to scan:

Balance 0 BTC

Received 0 BTC

TX 0

Instructions:
1. Pick a chain tab (Bitcoin, Ethereum, Tron, XRP, Solana, Sui, TON, Litecoin, ...).
2. Public key (hex)  ->  X, Y coordinates + that chain's address(es).
3. HASH160 / address ->  decoded for that chain (Bitcoin can also recover the key on-chain).
Everything is computed locally in your browser.

Educational / read-only tool. Key math and address encoding run entirely in your browser. Public-key recovery from an address only fetches public data from block-explorer APIs (blockstream.info, with blockchain.info as a fallback) and works only for addresses that have already spent funds — spending is what reveals the public key on-chain. No private keys are ever needed or transmitted.
