Up to date with rnode 0.13 alpha3

rchain-toolkit is a general purpose avascript/typescript library to interact with the RChain blockchain, and play with rholang expressions in node JS or the browser. It is not ready for production, not stable and the development is not completed yet.

It includes utils for easily deploying rholang code (smart contract), sending REV transactions, retreiving blocks, listen for data at unforgeable names, public names etc... All of the methods, parameters, and returned values are typed using typescript so the developer can comfortably code.

rchain-toolkit provides some GRPC utils since rnode's main API is GRPC, but it does not strictly assume the transport. This library builds proto objects based on rnode's proto definition files and some user parameters. GRPC is not included in the library, making it potentially elligible for the browser, GRPC and GRPC's proto-loader libraries must be installed separatly in your own project.

The examples folder contains example for each GRPC interface that is currently supported, each one of them exists in typescript and javascript.


See examples/



typescript must be installed on your machine

npm install -g typescript

Compile the .ts files in src directory to the main dist directory.

npm run build

Jest tests

The jest tests are all the tests that do not require proto-loader or GRPC, because it does not work under jest's runtime.

Run the jest tests

npm run test:jest

Full tests

The full tests are the tests that interact with the .proto files, and rnode. A local rnode instance must be running on localhost:40401 with --shard-name dev and automatic proposal (every 5 seconds for example).

Run the full tests

npm run build:tests
npm run test:full -- --private-key AAA --public-key BBB
npm run test:full -- --private-key 28a5c9ac133b4449ca38e9bdf7cacdce31079ef6b3ac2f0a080af83ecff98b36 --public-key 04be064356846e36e485408df50b877dd99ba406d87208add4c92b3c7d4e4c663c2fbc6a1e6534c7e5c0aec00b26486fad1daf20079423b7c8ebffbbdff3682b58
