Kava EVM contracts
Contracts for the Kava EVM used by the Kava blockchain. Includes an ERC20 contract for wrapping native cosmos sdk.Coins.
Setup
npm install
Test
npm test
Development
# Watch contract + tests
npm run dev
# Watch tests only
npm run test-watch
Deploying contracts to test networks
A deploy script is included in this hardhat project to deploy a contract directly to a network. To deploy the contracts to different networks:
npx hardhat run --network <network-name> scripts/deploy.ts
Configuration for various <network-name>s above are setup in the hardhat config.
Production compiling & Ethermint JSON
Ethermint uses its own json format that includes the ABI and bytecode in a single file. The bytecode should have no 0x prefix and should be under the property name bin. This structure is built from the compiled code with npm ethermint-json.
The following compiles the contract, builds the ethermint json and copies the file to the evmutil:
npm build
