• Anchor Message Payment: Anchor Message Payment is an application built with Next.js, TypeScript, and React that integrates with an Anchor Rust Solana on-chain contract. It allows users to create accounts where others can send messages with attached SOL (Solana tokens). Users can mark messages as "read" to claim 85% of the attached SOL, with the remaining 15% as a fee paid to a predefined keypair owned by the app's administrator. • Bad Email Crate: I created a Rust Cargo Crate that takes in an email as a variable and then compares the email domain to a list of over 10,000 known disposable emails. The crate has over five hundred downloads and a contribution from someone other than myself online.
