Nuts404.sol

Contract deployed with OpenZeppelin and Remix on Ethereum: 0x25559f0abbaf2a928239d2f419181147cc2dad74

This contract converts Nuts NFT ERC-721 standard to ERC-20 standard by locking Nuts NFT into the contract and minting 1:1 backed ERC-20 token, that can then be redeemed at any time:

Nuts (NUTS) <> Nuts404 (NUTS404)

Nuts404 is built on a generic simple abstract contract called W404 based on OpenZeppelin libraries (ERC-20, ERC-721, DoubleEndedQueue) and inspired from Pandora "ERC"404 experimental format.

WARNING: Current implementation of wrapping & unwrapping does not guarantee to get back to the same ERC-721 token(s) initially deposited. As unwrapping is implemented to withdraw the Nuts ERC-721 token(s) corresponding to the tokenId(s) stored on the back of the queue.

Usage

EDIT: You can use our friendly GUI to (un)wrap your NUTS NFTs, now available here: nuts.family/en/#wrap or here: app-nuts-family.netlify.app/#/wrap

WARNING: The following manual instructions are unsafe as they do not perform safety checks on the inputs you will provide to the Smart Contract and might cause a loss of assets. Recommended for advanced devs knowing what they are doing. (If you're a beginner, please use the GUI link provided above)

There are several ways to (un)wrap your NUTS with this contract (using web3/ethers scripts, etc). The following instructions represent just an example using Etherscan as a Web3 provider to interact with Nuts404.sol smart contract:

  1. Approval: On NUTS Contract, connect you wallet, call setApprovalForAll method allowing transfering NUTS for the Nuts404 Wrapper Contract (/!\ it will be for all your current and future NUTS as long as the value is set to true):
setApprovalForAll(
operator: 0x25559f0abbaf2a928239d2f419181147cc2dad74     (Nuts404 Wrapper Contract)
approved: true
)
  1. Wrapping: On NUTS404 Contract, connect you wallet, call deposit method in order to wrap NUTS NFTs into ERC20 tokens and set the tokenIds you want to wrap:
deposit(
tokenIds: [0, 31, 15]    (in this example: NUTS #0, #31 and #15 that you own will be wrapped into ERC20 tokens called Nuts404)
)

Click on write button to launch the call.

  1. Unwrapping:: NUTS404 Contract, connect you wallet, call withdraw method in order to unwrap NUTS404 tokens into NUTS NFTs and set the integer value you want to unwrap:
withdraw(
value: 3000000000000000000    (it will give you 3 NUTS NFTs but as said previously, it does NOT guarantee that it will be the #0, #31, #15 deposited previously)
)

Click on write button to launch the call.

WARNING: It is not recommended to (un)wrap more than 100 NUTS NFTS in order not to get 'running out of gas' errors.
