Standards Contributions
OpenZeppelin has helped drive standardization in the industry by authoring standards across ecosystems.
Ethereum
- ERC-1271: Standard Signature Validation Method for Contracts: A standard to verify a signature when the account is a smart contract. OpenZeppelin co-authored the standard and built contracts libraries in the OpenZeppelin Solidity Contracts Repo.
- ERC-1967: Proxy Storage Slots: A standard for defining a consistent location where proxies store the address of the logic contract they delegate to, as well as other proxy-specific information. OpenZeppelin authored the standard and built contracts libraries in the OpenZeppelin Solidity Contracts Repo.
- ERC-2771: Secure Protocol for Native Meta Transactions: A standard for a contract interface for receiving meta transactions through a trusted forwarder. OpenZeppelin co-authored the standard and built contracts libraries in the OpenZeppelin Solidity Contracts Repo.
Starknet
-
SNIP-5: Standard Interface Detection: A standard for a standard method to publish and detect what interfaces a smart contract implements. OpenZeppelin co-authored the standard and built contracts libraries in the OpenZeppelin Starknet Cairo Contracts Repo.
-
SNIP-12: Off-Chain Signatures: A standard for hashing and signing typed structured data as opposed to just hexadecimal (or felt) values in Starknet. OpenZeppelin provided feedback on the standard and built contracts libraries in the OpenZeppelin Starknet Cairo Contracts Repo.
Stellar
-
SEP-0049: Upgradeable Contracts: A standard that provides community guidelines and recommendations for safely upgrading the WASM bytecode of Soroban smart contracts. OpenZeppelin authored that standard and built contracts libraries in the OpenZeppelin Stellar Soroban Contracts Repo.
-
SEP-0050: Non-Fungible Tokens: A standard that defines a standard contract interface for non-fungible tokens. OpenZeppelin authored that standard and built contracts libraries in the OpenZeppelin Stellar Soroban Contracts Repo.
Battle Tested Libraries
Every OpenZeppelin library represents over a decade of security expertise, community validation, and real-world production use.
