EOSIO.CDT (Contract Development Toolkit)

Version : 1.7.0

EOSIO.CDT is a toolchain for WebAssembly (WASM) and set of tools to facilitate smart contract development for the EOSIO platform. In addition to being a general purpose WebAssembly toolchain, EOSIO specific optimizations are available to support building EOSIO smart contracts. This new toolchain is built around Clang 7, which means that EOSIO.CDT has the most currently available optimizations and analyses from LLVM, but as the WASM target is still considered experimental, some optimizations are incomplete or not available.

New Introductions

As of this release two new repositories are under the suite of tools provided by EOSIO.CDT. These are the Ricardian Template Toolkit and the Ricardian Specification. The Ricardian Template Toolkit is a set of libraries to assist smart contract developers in craftinng their Ricardian contracts. The Ricardian specification is the working specification for the above mentioned toolkit. Please note that both projects are alpha releases and are subject to change.
