Init Guide on Managing Auth Method for a PKP that Owns Itself

[Spacesai1or]

This is the corresponding guide for this code example

It covers:

1. Mint a new PKP using an EOA
   • Provided as the environment variable: process.env.ETHEREUM_PRIVATE_KEY_A
2. Add a Custom Authentication Method to the PKP that authenticates a signed SIWE message and verifies it's signed by ETHEREUM_PRIVATE_KEY_A
   • This is done by adding a Lit Action as a permitted Authentication Method for the PKP by uploading our Lit Action code to IPFS
3. Verify the Custom Authentication Method is permitted to be used for the PKP
4. Transfer ownership of the PKP NFT from ETHEREUM_PRIVATE_KEY_A to the PKP's Ethereum address
5. Get PKP Session Signatures using the Custom Authentication Method from step 2
6. Transfer some test Lit tokens from ETHEREUM_PRIVATE_KEY_A to the PKP's Ethereum address
   • This is necessary because we're interacting with the PKP Permissions contract on Lit's Chronicle chain to add and remove Authentication Methods, and we're required to pay gas for these onchain transactions
7. Initialize and connect a PKP Ethers Wallet using the PKP Session Signatures from step 5
8. Send a transaction to Chronicle to add a second Custom Authentication Method that authenticates a signed SIWE message and verifies it's signed by ETHEREUM_PRIVATE_KEY_B
   • This transaction executes the addPermittedAction function on the PKP Permissions contract
9. Verify the Custom Authentication Method is permitted to be used for the PKP
10. Get PKP Session Signatures using the Custom Authentication Method from step 8
11. Initialize and connect a PKP Ethers Wallet using the PKP Session Signatures from step 10
12. Send a transaction to Chronicle to remove the Custom Authentication Method from step 2 as a permitted method to be used with the PKP
13. Verify the Custom Authentication Method from step 2 is no longer permitted

The only note I have is that some blocks of code did not have any imports when they used methods in the Lit SDK. For example, the first two blocks and Transferring PKP Ownership to Itself. I'm sure the imports are elsewhere in the doc, but perhaps we want them anyways?

Great explanations on every part of the code. Reference links, splitting the code into blocks, and taking it piece-by-piece were appreciated for reading.

@awisniew207 Thanks Andrew, updated! The Transferring PKP Ownership to Itself doesn't need imports since it's just using variable defined in the snippet before it

My only comment is where this guide lives. I think we should add it as a subset of the user wallets section, versus creating a whole new dropdown. What do you think?

Agreed otherwise it's confusing what's the difference between User Wallets and PKPs if they have separate sections
