Token-Curated Registry

Codeship Status for skmgoldin/tcr

A string-keyed token-curated registry (TCR).


The only environmental dependency you need is Node. Presently we can guarantee this all works with Node 8.

npm install
npm run compile


The repo has a comprehensive test suite. You can run it with npm run test. To run the tests with the RPC logs, use npm run test gas.

Composition of the repo

The repo is composed as a Truffle project, and is largely idiomatic to Truffle's conventions. The tests are in the test directory, the contracts are in the contracts directory and the migrations (deployment scripts) are in the migrations directory. Furthermore there is a conf directory containing json files where deployments can be parameterized.

Deploying your own TCR

To deploy your own TCR, first open up conf/config.json. The paramDefaults object in the config JSON will specify the starting parameters your TCR is deployed with. In the token object, set deployToken to true if you want to deploy this TCR's token as part of the TCR deployment. You can specifiy initial recipients of the token in the tokenHolders array. If you have already deployed a token, set deployToken to false and provide the token's address in the address property. The token should be EIP20.

The package.json includes scripts for deploying to rinkeby and mainnet. Modify truffle.js and package.json if you need other networks. You'll need a secrets.json file with a funded mnemonic on the m/44'/60'/0'/0/0 HD path in the root of the repo to deploy. Your `secrets.json should look like this:

  "mnemonic": "my good mnemonic"

You can use to generate a mnemonic and derive its m/44'/60'/0'/0/0 address.


The repo consumes several EPM packages. dll and attrstore are libraries used in PLCRVoting's doubly-linked list abstraction. tokens provides an ERC20-comaptible token implementation. All packages are installed automatically when running npm run compile.
