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.

Base Mainnet — Molecule Labs core (v0.1.0)

The Lab smart-account stack is deployed on Base (chain ID 8453), the canonical chain for Molecule Labs:

Upgrade Pattern

The OclTokenizer 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

IP Token Cloning

IP Tokens (IPTs) are deployed using the EIP-1167 Minimal Proxy pattern:

• Each Lab tokenization creates a new LabToken clone

• Clones share implementation code but have independent state

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

• Query OclTokenizer.tokenized(labId) or use the indexer to find IPT addresses

Security Considerations

• Legacy core contracts (IPNFT, CrowdSale, TimelockedToken) have been audited by pashov

• The Molecule Labs core (OnChainLab account stack) was audited by Cyfrin in 2026 — see Audits

• Admin functions are protected by onlyOwner access control

• See individual contract pages for specific security notes
