A wallet's public address on one chain at one HD account index. Index i is
one account across every chain, grouped the way Phantom does it: Solana
m/44'/501'/i'/0', EVM m/44'/60'/0'/0/i, BTC m/84'/0'/0'/0/i. Allocate
indexes in order so a restored wallet's gap scan finds them all. Its secret's
kind says what it is: a BIP39 derivation (the wallet's primary address is
SOLANA account 0), a RAW key, or a LEGACY_MINTFX PDA. Holds no key material.
