X-Link

A collection of crates to force twitter users to gamble on Solana

Crates

• x-link-wallet: Deterministically create a Solana wallet from a twitter ID.
• x-link-client: Spin up a local HTTP client to interact with the Solana blockhain.
• x-link-types: Shared types between the client and wallet crates.
• x-link-utils: Utility functions shared between the client and wallet crates.
• x-link-solana: Solana backend functionality

X-Link Wallet

Links a twitter account to a Solana wallet. This is done by generating a Solana wallet from a HD wallet seed and using the twitter ID as the account and change. A twitter user ID is a u64, and account and change are both u32, so this works until Twitter fucks us.

This is a one way function The wallet can be generated deterministically from the twitter ID, but the twitter ID cannot be generated from the wallet.

X-Link Client

A local HTTP client to interact with the Solana blockchain.

Usage

To securely generate Solana wallets for twitter users, follow these steps:

1. Make sure the secret file is somewhere available to the program.
2. Make sure you know the passphrase
3. Run

cargo run --release --bin x-link-client -- --secret-file <path-to-secret-file> --port <port>

4. You will be prompted to enter the passphrase

There will be no confirmation that the passphrase is correct, the program will use the input passphrase to generate wallets. For any production environment, TEST with a known input and output to see if hte program is working correctly.

RPC Methods

Note on logging

If you want logging, make sure to specify the crates you want logging for in the RUST_LOG environment variable. For example:

export RUST_LOG=x_link_client=debug,x_link_solana=debug

With just RUST_LOG=debug, you will get all logs from all crates (including dependencies).
