Installation

$ npm test

Coverage

$ npm run coverage

Deploying contracts to localhost Hardhat EVM

$ npx hardhat node

You can connect to this RPC server via http://localhost:8545 with chain ID of 31337

Deploying contracts to local fork of a network

In order to successfully fork a network, the networks have to be defined in hardhat.config.ts with valid RPC URLs. In case of mainnet, ALCHEMY_API must be set to a valid URL in the .env file.

ALCHEMY_API="https://eth-mainnet.alchemyapi.io/v2/XXXXXXXXXXXX"

$ npm run fork --network=mainnet

You can connect to this RPC server via http://localhost:8545 with chain ID of the network.

Additionally, you can choose a block number to fork from by setting FORK_BLOCK_NUMBER env variable.

Deploying contracts to Ropsten

In order to successfully deploy to Ropsten, ALCHEMY_API_ROPSTEN must be set to a valid URL in the .env file. MNEMONIC_TEST_ACCOUNT must be set and the accounts must have some rEth for successful deployments.

ALCHEMY_API="https://eth-ropsten.alchemyapi.io/v2/XXXXXXXXXXXX"
MNEMONIC_TEST_ACCOUNT="seed phrase"

Generating GitBook docs

$ npx solidity-docgen --templates=templates

The output in the docs folder should be copied to the appropriate folder in the saddle-docs repo.
