Use filecoin test chain not hardhat

[lalexgap]

Currently we rely on spinning up a seperate instance of hardhat for nitro-rpc-client, we're not actually communicating with the filecoin test chain that gets started with a the devnet command.

I'm not sure if the filecoin test chain exposes an EVM-comptable JSON-RPC API, but we should investigate and use it, if it exists.

Depending on how your have setup devnet (docker vs non-docker), we can enable contract event listening on Boost.
If non-docker, then just edit the config.toml and set ContractDealsConfig.Enable = true . Restart boostd
If running in docker then, edit the file docker/devnet/boost/entrypoint.sh and add the below commands after sed -i 's|127.0.0.1|0.0.0.0|g' $BOOST_PATH/config.toml line and reinit devnet.
awk '/ContractDeals/{ rl = NR + 1 } NR == rl { gsub( /"Enabled = false"/,"Enabled = true") } 1' $BOOST_PATH/config.toml > $BOOST_PATH/config.toml.tmp
mv $BOOST_PATH/config.toml.tmp $BOOST_PATH/config.toml
For the running devnet, shut edit config.toml and set ContractDeals.Enabled = true and restart the container (edited)

We need to enable FEVM in the lotus config file.

Currently getting a permission error, probably need to do this https://lotus.filecoin.io/reference/basics/api-access/

Note: I’m assuming we’re using a restartable devnet from this [branch](#7)

• Stop your local running devnet if running

• Modify your lotus config to enable fevm: https://lotus.filecoin.io/lotus/configure/ethereum-rpc/

• Restart devnet by running ./devnet -i=false

• Get an auth token by running: lotus auth api-info --perm admin

• Note: This depends on this go-nitro branch](Tweak script to work with filecoin devnet go-nitro#1352). This branch allows for auth tokens to be passed in, and removes some hardcoded urls in our scripts. The config files have also been updated with the chainurl and chainauthkey.

• However you'll need to update the config files with your token generated from before.

# Update this with token you generated from before
chainauthtoken = "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJBbGxvdyI6WyJyZWFkIiwid3JpdGUiLCJzaWduIiwiYWRtaW4iXX0.PyJt3GZtJrLu-bs_3Kmy1VrFpcGoCZEZ8JhX-YWQ4Pc"
# This is the default RPC endpoint for the lotus daemon
chainurl = "ws://127.0.0.1:1234/rpc/v1"

• Run the go-nitro test script go run ./scripts/start-rpc-servers.go
• Currently we’ll get an error when we try to deploy the contract. Sending funds to the account doesn’t seem to help 😟

Note:

• [Enable contract monitoring on boost](https://boost.filecoin.io/experimental-features/fvm-contract-deals)? Haven’t done this yet and I’m not sure if we need to. Just wanted to flag it.
