I. What is sudoswap?

Sudoswap is a platform that allows you to trade your NFTs. Some witches in Crypto Coven have used this platform to facilitate swaps of witches. Sudoswap reduces some of the risk for both parties by being the intermediary for trading NFTs.

You can set up a trade on sudoswap in a few easy steps. Before setting up a trade, make sure you have some Ethereum (ETH) in your wallet to cover gas fees ($60-80 in total gas fees, can be split with the other party). Also, please be aware that sudoswap can be glitchy which may result in losing some gas while setting up a trade.

II. Best practices in swapping safety

• Be wary of random links shared on Discord. Make sure you are using the official Sudoswap website when making a swap (sudoswap.xyz).
• As always, make sure you trust the person you are swapping with. Platforms like sudoswap can be a precaution when you don’t know the person, but is not a replacement for trust: make sure you feel comfortable trading with that individual.
• If you’re receiving a swap, confirm the details of the assets being traded and that the assets are indeed owned by the people swapping. You can also see your ‘pending swaps’ listed in the sudoswap menu bar after you’ve connected your wallet (if they added your wallet address under the “for” section), which is probably safer to navigate than clicking through a discord link. When in doubt, it’s safer to create the swap link yourself.
• Before you initiate a trade, make sure you have the confirmed double opt-in so you don’t lose gas fees if they bail.

III. What do I need to prepare for my swap?

You'll want to grab a few important pieces of information, listed below, as well as make sure have some Ethereum (ETH) in your wallet to cover gas fees.

Here are the bits you want:

• Swappee’s Wallet Address: Ask the person you're trading with for their wallet address to ensure they are the only person who can accept the swap. You can also get this by navigating to the NFT you’re swapping for on Opensea and copying the owner’s wallet address under their profile photo (good to verify they gave you the correct address by comparing with the one on their Opensea profile!)

• Smart Contract Address: You'll need the smart contract address of the project you want to swap for (also known as “Asset address” when swapping). Some projects will post the contract address in Discord (like Crypto Coven).

  • Here’s an example of how to find it in case the project doesn't post it openly (toggle)

• Token ID/Token Standard: Finally, you need to find the "Token ID" for the NFT you’d like to receive and note the "Token Standard" (also known as “Asset type” when swapping). Navigate to the NFT you’re trading for on OpenSea, and you’ll find the Token ID and Standard under the details section. The token standard for Crypto Covens is ERC-721.

  

Now you're ready to create your swap!
