memos

A minimal Anchor program that stores text memos in PDA accounts. Each store_memo call writes a new Memo account at ["memo", count], bumps the MemoCounter at ["counter"], and emits a MemoStored event via self-CPI (emit_cpi!).

Prerequisites

• Rust 1.89.0 (pinned via rust-toolchain.toml)
• Solana CLI
• Anchor CLI 1.0.0
• Node.js and Yarn (Anchor.toml is wired for yarn)

Test

This spins up a local validator, deploys the program, and runs the TypeScript test suite in tests/memos.ts.
