## README

# 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.
- Mirrored Token contract address: `ADDRESS.ACA`, `ADDRESS.AUSD`...(`./contracts/utils/AcalaAddress.sol` or `./contracts/utils/KaruraAddress.sol`)
- Docs [contracts/docs/token/Token.md](./contracts/docs/token/Token.md)
