Predeploy-contracts

Generate bytecode for predeployment of ERC20 smart contracts in Acala.

Build

Run yarn to install dependencies.

Generate bytecode

To generate bytecode, run yarn run generate-bytecode.

The generated bytecode JSON file would be ./resources/bytecodes.json.

Development

The token list for ERC20 smart contracts is in ./resources/acala_tokens.json and ./resources/karura_tokens.json. symbol and address are needed for each token, for instance:

{
  "symbol": "ACA",
  "address": "0x0000000000000000000100000000000000000000"
}

All of the tokens and predeployed system contracts have generated code in ./contracts/utils/AcalaAddress.sol and ./contracts/utils/AcalaAddress.js for Acala, ./contracts/utils/KaruraAddress.sol and ./contracts/utils/KaruraAddress.js for Karura, we can use it directly.

Predeployed System Contracts

ERC20 Contracts

These ERC20 contracts make native and cross-chain tokens available inside Acala EVM.
