Operations

Running the OP Stack devnet

The single-sequencer L3 in infra/op-stack: L1 as an anvil fork of Base Sepolia, the four OP services, config generation via op-deployer, and the make targets (with a PowerShell path on Windows).

infra/op-stack is a Docker Compose stack that runs a complete OP Stack rollup with one sequencer. It's how you get real L3 blocks; the privacy core itself runs fine without it.

The services

ServiceRole
L1 (anvil)An anvil fork of Base Sepolia, standing in as the settlement layer.
op-gethThe L3 execution engine.
op-nodeThe rollup node / consensus client.
op-batcherPosts L3 transaction batches to L1.
op-proposerPosts output roots (DisputeGameFactory-based).

Generate config & boot

bash
cd infra/op-stack
cp .env.example .env
make generate        # genesis + rollup config via op-deployer
docker compose up -d

make generate runs the generation scripts (scripts/generate.sh, or generate.ps1 on Windows) to produce the genesis and rollup config with op-deployer. The lifecycle targets:

make generate
Produce genesis + rollup config.
make up
Start the stack.
make down
Stop the stack.
make reset
Tear down and clear state.

Windows

A PowerShell generation script (scripts/generate.ps1) mirrors the shell path, so the devnet generates on Windows without a POSIX shell.
