Infrastructure & Patterns
Sixteen standards covering interface detection, registries, proxy upgrades, deterministic deployment, minimal proxies, init-arg meta-proxies, blueprint contract format, diamond storage, off-chain data retrieval, cross-chain messaging gateways, modular smart accounts, and meta-transactions. Several of these are straightforward ports; others are subsumed by Neo's manifest-driven contract model or its native oracle service.
