Please use [CDT](https://github.com/AntelopeIO/cdt) instead.\n\n# Blanc\n\n**BLockchAiN Contract toolchain**\n\nWelcome to Blanc!  Blanc is a toolchain for WebAssembly-based blockchain contracts.  Currently, Blanc supports [EOSIO](https://github.com/EOSIO) and [CosmWasm](https://github.com/CosmWasm) (experimental), but we have a plan to support other WebAssembly-based contracts like [Substrate](https://github.com/paritytech/substrate/tree/df501229/frame/contracts).  In EOSIO ecosystem, block.one already provides the official version of contract toolchain [eosio.cdt](https://github.com/EOSIO/eosio.cdt), but Blanc takes a different approach from it.  eosio.cdt uses the modified version of Clang/LLVM, so you have to wait for block.one's updates to utilize the latest version of Clang/LLVM.  Blanc was adapted from eosio.cdt, but uses the vanilla Clang/LLVM for easier maintenance and faster adoption of state-of-the-art technologies.  At this point in time (Oct, 2021), eosio.cdt uses Clang-9, but Blanc uses Clang-13.  The only thing you need to care about is that your Clang/LLVM installed in your system supports Clang plugins and WASM binary generation.  You should have Clang-12 or higher, and in MacOS, you need to install `llvm` by brew.  Clang/LLVM installed by Xcode were not built for supporting plugins.\n\nBy using the latest Clang/LLVM, generated WASM binaries will have smaller size by about 20%. (eg. `eosio.token` 17KB \u0026rightarrow; 13.5KB, `eosio.system` 305KB \u0026rightarrow; 241KB)  All unit tests provided by eosio.cdt and [eosio.contracts](https://github.com/EOSIO/eosio.contracts) are passed and all generated ABIs are identical.\n\n\n## Nota Bene\n\nWe changed branch strategy. The branch for daily development is `master` now, so if you want to build from the source, please use `release` branch for stable version.\n\n## Binary Releases\n\nThe prebuilt binares are provided for Ubuntu 20.04 and MacOS Big Sur.\n\n### Ubuntu 22.04\n\n```sh\nsudo add-apt-repository ppa:conr2d/blanc\nsudo apt install blanc\n```\n\n### MacOS Ventura\n\n```sh\nbrew tap haderech/blanc\nbrew install blanc\n```\n\n## Installed Tools\n\n* blanc++\n* blanc\n* blanc-ld\n* blanc-pp\n* blanc-ar\n* blanc-ranlib\n\n## Contributing\n\n[Contributing Guide](./CONTRIBUTING.md)\n\n[Code of Conduct](./CONTRIBUTING.md#conduct)\n\n## License\n\n[MIT](./LICENSE)\n\n## Important\n\nSee [LICENSE](./LICENSE) for copyright and license terms.\n\nAll repositories and other materials are provided subject to the terms of this [IMPORTANT](./IMPORTANT.md) notice and you must familiarize yourself with its terms.
