Further examples (created using an older cargo-stylus version and an older stylus-sdk version)

⚠️ IMPORTANT: These examples were created using an older version of cargo-stylus (v0.1.x or v0.2.x), and with an older stylus-sdk version (< v0.5.0) and might not be compatible with recent versions of cargo-stylus without making some modifications to the source code.

Examples built with cargo-stylus v0.1.x

• ERC20 Examples
  • Stylus Permit [cs v0.1.x] - An ERC20 Permit example in Rust
  • Stylusmate [cs v0.1.x] - An ERC20 with Ownable module in Rust
  • Rustmate ERC20 [cs v0.1.x] - An ERC20 + EIP-2612 implementation equivalent to Solmate
• ERC721 Examples
  • https://github.com/cygaar/ERC721Stylus/ (Rust) [cs v0.1.x]
  • https://github.com/0xcacti/stylus_erc721 (Rust) [cs v0.1.x]
  • https://github.com/gvladika/stylus-erc721 (Rust) [cs v0.1.x]
• Uniswap V2 In Wasm [cs v0.1.x] - A Uniswap v2 proof of concept implementation
• RKFall NFT [cs v0.1.x] - A Rust based project that uses gravitational field computation for generating NFTs

How to make this code compatible with cargo-stylus v0.3.x and stylus-sdk v0.5.0

When trying to use the latest version of cargo stylus on a project created first on cs v0.1.x you might run into this error:

error: no library targets found in package `your-package-name`

Here are some tips for making this code compatible with the latest version:

• Use lib.rs instead of main.rs for the main logic of your program
• Add also a [lib] target to your Cargo.toml file if you don't have one
• Update the stylus-sdk version used to v0.5.0
• Modify the function names from camelCase to snake_case

Examples built with cargo-stylus v0.2.x

• Zk-sunade [cs v0.2.x] - An optimized , handwritten implementation of Groth16 using Arbitrum Stylus
• Stylus Proxy [cs v0.2.x] - An example contract for implementing minimal proxy pattern in Stylus
• Stylus AssemblyScript Example [cs v0.2.x] - Sieve of Erathosthenes implemented with AssemblyScript

How to make this code compatible with cargo-stylus v0.3.x and stylus-sdk v0.5.0

When trying to use the latest version of cargo stylus on a project created first on cs v0.2.x you might run into this error:

missing import pay_for_memory_grow

To make the code compatible with the latest version, you might need to update the stylus-sdk version used to v0.5.0
