Ethereum Debugger (for smart contracts in Solidity).
python3
Ethereum node running in archive mode with debug api. E.g. geth:
geth --rpc --rpcapi eth,debug --gcmode archive
By default localhost:8545 endpoint is used.
Compiled contracts in format produced by solc with --combined-json option.
Each contract called in transaction should be compiled with the same solidity
