Solana Payments & Commerce

By the end you can take real money on Solana end to end, a stablecoin Solana Pay checkout and POS, a webhook-driven back office with reconciliation and refunds, non-custodial subscriptions with dunning, on/off ramps, and x402/MPP machine payments, assembled into one running commerce stack on devnet — where the course touches regulation, it is an engineering framing of the seams, not legal advice. This is a local-toolchain course from the first lab: module one already needs Node 24 and installs packages on your machine, module two adds the Anza Agave CLI (`solana` plus `spl-token`), and from there every lab runs npm workspaces locally against devnet; one step in module eight — `cargo install kora-cli` — additionally needs a Rust toolchain.
