chain-end

chain-end

For programmatically deploying an arbitrary number of pre-compiled smart contracts, and, Soon:tm:, interacting with them in all sorts of interesting ways.

usage

The imported package contains three modules:

• the contracts object, which contains the JSON of the default contracts
• the Deployer class
  • instantiate a deployer using Deployer(web3Provider, accountAddress, gasLimit)
    • for use with MetaMask, use Deployer(web3Provider, accountAddress) to let MetaMask handle transaction gas
  • add a contract type to deploy instances of it using deployer.addContract(compiledJSON)
    • compiledJSON must be an undeployed, compiled Truffle artifact, i.e. the output of truffle compile
  • deploy and access a deployed contract instance using const instance = deployer.deploy(contractName, constructorParameters)
    • contractName must be a key from contracts or the name of a contract added using addContract
  • consult src/deployer.js for additional methods you may want to use
• the deploy function, which exposes the internal API of Deployer for stateless deployment
  • deploy directly using: deploy(contractJSON, constructorParams, web3Provider, web3Account, gasLimit)
  • gasLimit is optional
• the getInstance function, which retrieves a deployed contract given its artifact, its deployed address, a provider, and (optionally) a sender account
• the callInstance function, which calls a specified function from a given TruffleContract instance and returns the result
