A wasm-blob will generate a syntax. Seed is under rapid development, so there may be breaking changes at times. Hopefully this has demonstrated that getting Rust code running in the browser via wasm is pretty achievable even for projects that aren't a drop-in fit for the browser's runtime model. To keep things simple with Wasm's limitations mentioned in the introduction example, instead of displaying a string, we will add two numbers together and display the result. This means you can write smart contracts in whichever language you're familiar with, though we're partial to Rust due to its lack of runtime overhead and inherent security properties. The example shown here will be a simple smart contract that serves as a counter, incrementing, decrementing, and returning the counter value. Rust by Example.
