Ethereum payment channels implementing the Perun protocols.

The contracts directory contains the smart contracts, currently

• LedgerChannels: Single-deployment ledger channels smart contract.
• Migrations: Truffle migrations.

Truffle and typescript are assumed to be installed globally (yarn global add truffle typescript or use your distro packages, e.g., pacman -Sy typescript for Arch Linux). Other dependencies are installed with yarn. The truffle configuration is set to use the system's solc solidity compiler, so install that one too (Arch Linux: pacman -Sy solidity).

is done with the truffle framework and typescript.

Compilation consists of three steps. First, the contracts are compiled using solc, by running truffle compile or yarn build:contracts. Then, typescript typings are generated using typechain for type-safe development of tests and applications (yarn build:types). Finally, the test and applications, written in typescript, are transpiled to javascript (yarn build:js). All three build steps can also be invoked at once with yarn build.

First start a local Ganache blockchain and then issue truffle migrate. This deploys truffle's Migration contract as well as one instance of our contracts.

All tests are written in typescript. The runnable javascript tests are generated as part of yarn build. After this step, tests are run by yarn test or directly truffle test.
