🗝️ Address from Key

Derive an address from a secp256k1 public key — the standard Cosmos way or the Ethereum-style (ethsecp256k1) way.

Public key (hex, base64, or PubKey JSON with a "key" field)

Chain Key type

How it works

secp256k1 (most Cosmos chains): address = RIPEMD-160(SHA-256(33-byte compressed public key)).

ethsecp256k1 (Injective, Evmos, Cronos and other Ethermint chains): address = last 20 bytes of Keccak-256(64-byte uncompressed public key without its 0x04 prefix) — the same bytes as the account's Ethereum 0x address.

Both kinds are shown as bech32 with the chain's prefix. Uncompressed keys are compressed automatically for the Cosmos form.
