 **Note that Stylus smart contracts will need to be re-activated once per year (365 days) or whenever a upgrade to Stylus (which will always involve an ArbOS upgrade), even if they are in the cache. This re-activation can be done using [`cargo-stylus`](https://github.com/OffchainLabs/cargo-stylus), a cargo subcommand for building, verifying, and deploying Arbitrum Stylus WASM contracts in Rust.**
