Address Derivation

Address derivation is the deterministic process of producing blockchain addresses from a public or extended key following a chain's encoding rules.

An address is derived from a public key by hashing and encoding it according to each chain's rules, and hierarchical deterministic wallets extend this to derive many addresses from one seed along a path. EVM addresses take the last twenty bytes of a Keccak hash; Bitcoin encodes hashed keys as base58 or bech32; TRON and TON have their own schemes. Deriving fresh addresses per user underpins deposit tracking. Our wallet-infrastructure primitives derive addresses across chains from extended keys and monitor their activity against archive data.
