Contracts

Molecule Protocol consists of smart contracts deployed across Ethereum Mainnet and Base L2. These contracts enable the creation, tokenization, and trading of intellectual property assets.

Upgrade Pattern

IPNFT and Tokenizer contracts use the UUPS (Universal Upgradeable Proxy Standard) pattern:

• Proxy contracts hold state and delegate calls to implementation contracts

• Only the contract owner can authorize upgrades

• Contract addresses remain stable across upgrades

CrowdSale and SchmackoSwap are not upgradeable - they are deployed as standard contracts.

IPToken Cloning

IPTokens are deployed using the EIP-1167 Minimal Proxy pattern:

• Each IP-NFT tokenization creates a new IPToken clone

• Clones share implementation code but have independent state

• No fixed deployment address - each IPToken has a unique address

• Query Tokenizer.synthesized(ipnftId) or use the indexer to find IPToken addresses

Security Considerations

• Core contracts (IPNFT, CrowdSale, Tokenizer, TimelockedToken) have been audited by pashov

• Admin functions are protected by onlyOwner access control

• See individual contract pages for specific security notes
