Consumer Crypto Architecture Patterns

Architecture patterns that precede chain selection: smart account permissions, gasless onboarding, onchain identity, and the consumer crypto stack as a whole.

Decide the pattern before locking in a chain. Each page lists every competing approach honestly — ERC-4337, EIP-7702, Safe modules, Solana program-derived accounts, LUKSO LSPs — with explicit pros, cons, and "when each wins" recommendations.

Where this fits.
