title: Infrastructure & Patterns — ERC ↔ Neo Mirror
description: Proxies, registries, modular contracts, deterministic deployment — Ethereum infrastructure standards mirrored to Neo C#.
---

# 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.
