Final commit in which `main` agents are compatible with the currently deployed `testnet` v0 environment

This is the last commit on main in which agents are compatible with the currently deployed testnet environment, v0.
Following this tag, #519 will be merged, which updates the agents to use contract ABI that matches what is currently on main that is incompatible with the current testnet environment. A future testnet deploy will occur, at which point main will be back in sync with the testnet environment.
