Predeploy Setheum Ethereum Virtual Machine (SEVM) Contracts
Generate bytecode for predeployment of ERC20 smart contracts in Setheum.
Run yarn to install dependencies.
Generate bytecode for predeployment of ERC20 smart contracts in Setheum.
To generate bytecode, run yarn run generate-bytecode.
The generated bytecode JSON file would be ./resources/bytecodes.json. The contracts are in ./contracts/ directory.
It can also be generated from the specified file, run yarn run generate-bytecode [tokens.json path] [bytecodes.json output path]
The token list for ERC20 smart contracts is in ./resources/tokens.json. Symbol and address are needed for each token, for instance:
{
"symbol": "SETM",
"address": "0x0000000000000000000000000000000001000000"
}
These ERC20 contracts make native and cross-chain tokens available inside SetheumEVM (SEVM).

These contracts will make Setheum's DeFi primitives (SetMint, HighEnd LaunchPad, Al-Ethaar) available in SetheumEVM (SEVM).
These conracts will enable bridging between EVM Compatible Chains and Setheum (ie. Setheum-Ethereum Bridge) using chainbridge-solidity.
