Clone https://github.com/edgeandnode/local-network

Use branch tmigone/horizon

For a forked environment, run with:

HARDHAT_VAR_LOCALHOST_MNEMONIC=<governor_mnemonic> \\
FORK_RPC_URL=<rpc_url> \\
	docker compose up graph-contracts --build

• <governor_mnemonic> is the protocol governor on the forked chain
• <rpc_url> is the RPC to be used for the fork
• This will start a chain with the contracts, an ipfs node and a graph-node.

If you want a non forked environment just run:

docker compose up graph-contracts --build
