Contract Deployment Patterns
Transparent Proxy Pattern –  Uses a contract that includes an admin address as well as logic for how to delegate calls to an implementation. 

​

Diamonds Multi-Facet Proxy Pattern (ERC-2535) – Codifies the concept of a diamond which is a modular smart contract system that can be upgraded/extended after deployment and which has virtually no size limit.

Account Abstraction and Intents Patterns

Account Abstraction Pattern – Introduces an account access layer to make working with crypto-based accounts more secure, flexible, and intuitive. 

​

Intents Pattern – Introduces the concept of an intent which is signed a set of declarative constraints that allows a user to outsource transaction creation to a third party without relinquishing full control to the transacting party. 

Bridging, Cross-Chain Messaging, and Oracle Patterns 
Cross-Chain Messaging Patterns – Facilitates the transfer of tokens, data, and smart contract commands across blockchain networks.

Oracle Patterns – Addresses techniques used to obtain onchain and offchain data including using multiple oracles, constraining or extending the protocol/network sources used, addressing floors, ceilings, and other edge cases, and factoring in data ranges, averages, smoothing, and other data presentation techniques.
 

Gas Optimization and Other Utility Patterns 

Merkel Whitelist Pattern – Storing whitelists via a Merkel tree with each leaf represents a whitelisted address. The root of the tree is a single hash that represents the whole set of addresses, which can then be checked with a proof in a contract.
