These contracts enable the creation, tokenization, and trading of intellectual property assets. #### Ethereum/Base Mainnet | Network | Contract | Address | Verified URL | Function | | ---------------- | -------------- | ------------------------------------------ | ------------------------------------------------------------------------------------ | -------------------------------------------------------------------------------- | | Ethereum Mainnet | IPNFT | 0xcaD88677CA87a7815728C72D74B4ff4982d54Fc1 | [Etherscan](https://etherscan.io/address/0xcaD88677CA87a7815728C72D74B4ff4982d54Fc1) | IP-NFT ownership | | Ethereum Mainnet | CrowdSale | 0xF0A8D23F38E9CbBe01C4Ed37f23BD519b65BC6C2 | [Etherscan](https://etherscan.io/address/0xF0A8D23F38E9CbBe01C4Ed37f23BD519b65BC6C2) | Token sales | | Ethereum Mainnet | SchmackoSwap | 0xc09b8577c762b5e97a7d640f242e1d9bfaa7eb9d | [Etherscan](https://etherscan.io/address/0xc09b8577c762b5e97a7d640f242e1d9bfaa7eb9d) | IP-NFT trading | | Ethereum Mainnet | AccessResolver | 0xc130e0b49840b266A49F62C0Cc77e353E0C99cD0 | [Etherscan](https://etherscan.io/address/0xc130e0b49840b266A49F62C0Cc77e353E0C99cD0) | File access control (v2 — signer predicates only; the role system lives on Base) | | Base | LaunchFactory | 0xD915e2bA3E22352344de245aC227EcaC0776a1A4 | [BaseScan](https://basescan.org/address/0xD915e2bA3E22352344de245aC227EcaC0776a1A4) | Catalyst token launches | #### 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: | Contract | Address | Verified URL | Function | | ------------------------------ | ------------------------------------------ | ----------------------------------------------------------------------------------- | ------------------------------------------- | | OnChainLabFactory | 0xECdF4f05384056507485C90aeAb0a83268760D6E | [BaseScan](https://basescan.org/address/0xECdF4f05384056507485C90aeAb0a83268760D6E) | Lab account creation (mint & create) | | LabNFT (proxy) | 0x9F96027eeAFb9ad5F2b5d7043B36Ee96B2EeBE92 | [BaseScan](https://basescan.org/address/0x9F96027eeAFb9ad5F2b5d7043B36Ee96B2EeBE92) | Lab ownership NFT (ERC-721) | | ERC7484Registry | 0x1Ab5Ba4300613F7346835b2BE7E2D10Ce6125eF5 | [BaseScan](https://basescan.org/address/0x1Ab5Ba4300613F7346835b2BE7E2D10Ce6125eF5) | Module attestation registry | | RootValidator | 0xb31d39ECc0cb26478E258C8f7e9C906115f494f6 | [BaseScan](https://basescan.org/address/0xb31d39ECc0cb26478E258C8f7e9C906115f494f6) | Default signature validator | | MoleculeOclDidRegistry (proxy) | 0x6cd3Cf3c34a18Bf48F90590c3a57708F175b2eE3 | [BaseScan](https://basescan.org/address/0x6cd3Cf3c34a18Bf48F90590c3a57708F175b2eE3) | DID linking for Labs | | AccessResolver (v3) | 0x89a14Be8f7824d4775053Edad0f2fA2d6767b72B | [BaseScan](https://basescan.org/address/0x89a14Be8f7824d4775053Edad0f2fA2d6767b72B) | Roles & file access control | | OclTokenizer (proxy) | 0x62F532C3f563D974deEc103AAb8cC597f4f9c84E | [BaseScan](https://basescan.org/address/0x62F532C3f563D974deEc103AAb8cC597f4f9c84E) | Lab tokenization (IPT factory) | | OclTermsPermissioner | 0x125A12C880934826c80A54ce216B6c1F542603eE | [BaseScan](https://basescan.org/address/0x125A12C880934826c80A54ce216B6c1F542603eE) | Membership-agreement signature verification | #### Sepolia Testnet
