AI Analysis

●MidBig BrainNiche Gem

Server-side transaction construction keeps keys safe, but there's no SDK to install.

Strengths

•Threat model explicitly addresses client-side compromise and CSRF attacks.
•Architecture diagram clearly separates database, wallet, and blockchain responsibilities.
•Solves the audit trail problem without violating non-custodial guarantees.

Weaknesses

•No reference implementation, SDK, or code snippet to copy-paste.
•Solana-specific examples limit immediate applicability to EVM chains.
