Rentable Protocol

NFT Renting Protocol

Archived => https://medium.com/@emiliano.bonassi/rentable-is-shutting-down-b80731ef4326

Architecture

• Rentable.sol: protocol core logic. It holds all the NFT deposited.
• ORentable.sol: ERC721 token representing deposits (and asset ownership). Each NFT collection has a respective ORentable with the same token ids. It is minted on deposit and burnt on withdraw. ORentable can contain custom logic and use Rentable.proxyCall to operate on deposited assets.
• WRentable.sol: ERC721 token, wrapper of the original NFT representing the rental. Each NFT collection has a respective WRentable with the same token ids. It is minted when rental starts and burnt on expiry. WRentable.ownerOf reflects rental duration (i.e., renter loses WRentable owerniship when rental period is over). WRentable can contain custom logic and use Rentable.proxyCall to operate on deposited assets.
• ICollectionLibrary.sol: interface to implement hooks on protocol events (e.g., postDeposit, postRent) for a given collection. Governance can set a Collection Library via Rentable.setLibrary.
• SimpleWallet.sol: smart wallet used by the renter, cannot withdraw the rented assets but only interact with allowed protocols/methods. Implements EIP1217 for Standard Signature Validation enabling Wallet Connect logins.
• WalletFactory.sol: factory for smart wallets, used by Rentable to generate upgradeable smart wallets for users.

The following diagram shows the main components and their interactions. ERC721 NFT Collection represents a generic NFT collection (e.g., Decentraland LAND) and it is not part of Rentable.

Main flows

• Rentee deposits an NFT (without listing)
  • Call safeTransferFrom(ownerAddress, rentableAddress, data) on the NFT collection contract with empty data
• Rentee deposits and lists an NFT
  • Call safeTransferFrom(ownerAddress, rentableAddress, data) on the NFT collection contract with RentableTypes.RentalConditions encoded in the data field
  • Rentee receives a ORentable token representing the deposit (and asset ownership)
• Rentee changes the rental conditions of a listed NFT
  • Call createOrUpdateRentalConditions on Rentable
• Rentee delists an NFT
  • Call deleteRentalConditions on Rentable
• Rentee withdraws an NFT
  • Call withdraw on Rentable
• Renter rents an NFT
  • Call rent(address tokenAddress, uint256 tokenId, uint256 duration) on Rentable
    • if payment token is Ether, renter must pay pricePerSecond*duration
    • if payment token is ERC20 or ERC1155, renter must have an amount equals to pricePerSecond*duration and approve Rentable to transfer it
  • Renter receives a WRentable
  • Renter receives the original NFT in its own SimpleWallet (cannot withdraw, only interact on owner approved protocols/methods)

Requirements

To run the project you need:

• Python 3.8 local development environment and Node.js 14.x development environment for Ganache.
• Brownie local environment setup. Install instructions.
• Foundry. Install instructions

Test

yarn test

Installation

To use the tools that this project provides, please pull the repository from GitHub and install its dependencies as follows. You will need yarn installed. It is recommended to use a Python virtual environment.

git clone https://github.com/rentable-world/rentable-protocol
cd rentable-protocol
yarn install --lock-file
pip install -r requirements-dev.txt

Usage

1. Choose network
2. Deploy contracts (or use already deployed ones)
3. Prepare your account
4. Use network console

Remember to add the network to your Metamask

Network

Run the following commands respectively and keep the session open. Network is ephemeral, when you close the command you reset it.

Local Testnet

yarn network:testnet

Mainnet Fork

Useful to interact with other protocols in mainnet via a local fork.

You need local env variables for Etherscan API and Infura (ETHERSCAN_TOKEN WEB3_INFURA_PROJECT_ID).

Set them in .env file following .env.example

yarn network:mainnet-fork

Deploy contracts

yarn deploy:testnet

Use network console

Run the console

yarn console

and interact directly with contracts

Example: Check owner of tokenId = 4 for NFT with smart contract address 0x734f99154988a737ae7159594Ebf828eB6761645

>>> t = TestNFT.at('0x734f99154988a737ae7159594Ebf828eB6761645')
>>> t.ownerOf(4)
'0x5898D8D9a8895dBBd3d035724FA1Bc252876cC22'
>>>

Run tests

yarn test
