VeRT
VM emulation RunTime for WASM-based blockchain contracts
VeRT is a blockchain virtual machine emulator for WASM-based contracts like EOSIO. (CosmWasm and Substrate will be supported.) It uses the built-in WebAssembly object in JavaScript, so can be executed on any modern browsers or runtime environments without additional dependencies. It doesn't support the full specification of each blockchain state-machine, but can be used to run and test smart contracts before deployment. The focus of VeRT is on the better compatibility than the performance, so it can be integrated with development pipelines.
- Run and test smart contracts
- Minimum dependencies (No native wrapper, docker or remote connection)
- Volatile key-value store with state rollback
Requirement
- WebAssembly binary with the exported memory (blanc v0.9.2 or higher)
- JavaScript runtime with WebAssembly BigInt support (nodejs v16 or higher)
Installation
npm install vert
Test

npm run test
- nodejs v14
