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

WARNING: No friendly GUI available yet to (un)wrap your NUTS NFTs. The following 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.

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
)

2. 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.

3. 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: 3    (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.
