Features

• Zero-copy account deserialization (no heap allocations)
• Token-2022 (SPL Token Extensions) integration
• ZK compressed tokens via Light Protocol
• Three-wallet security architecture (Treasury, Mint Authority, Transfer Authority)
• Rate limiting (per-transaction and daily)
• On-chain metadata (Token Metadata Interface)

Build

Requires Solana CLI and the SBF toolchain.

cargo build-sbf

# Unit tests
cargo test --lib

# Full test suite (requires SBF binary)
cargo build-sbf && cargo test

Verify Build

This program is verified on Solana Explorer. To verify locally:

solana-verify get-program-hash ZUPYzr87cgminBywohtbUxnaiFMwXNy8A5pD9cCcvVU
solana-verify get-executable-hash target/deploy/zupy_token_program.so

Both hashes must match.
