A proper multi-chain wallet implementation that handles the messy reality of blockchain operations. Covers EVM chains via DeBank and Solana via Birdeye, with gas sponsorship that falls back to user-paid when needed. The policy system is notably well-documented since Privy's rule precedence (DENY always wins) trips up most implementations. Includes all the signing primitives you'd expect: EIP-191, EIP-712, transaction signing, plus broadcast capabilities. The three policy modes (allow-all, deny-all, whitelist) cover the main security patterns without the usual footguns. Solid choice if you need wallet functionality that actually works in production rather than just demos.
