Address from Private Key (Multi-Chain)
Enter a 32-byte raw private key (hex) to derive valid addresses for multiple blockchains.
Since many chains share elliptic curves (secp256k1), the same private key corresponds to valid addresses on all of them.
Security Warning: This tool runs 100% in your browser. Keys are never sent to any server. However, do not paste keys that hold real value. Use for testing/recovery only.
Input Key
Enter 64 hex characters (32 bytes).
Derived Addresses
Enter a key to see addresses.
About the Address From Key
Derive the public address for any secp256k1 private key. Works for Ethereum, BSC, Polygon, and every EVM chain since they share the same key derivation.
Paste a private key to see the corresponding public address computed locally using the same elliptic curve math that wallets use. Keys never leave the browser.
How to use
- Paste your private key (64 hex characters).
- The address appears instantly.
- Copy for use in your development or testing.
