# Solution guides

> Solution guides that sequence the OP Stack documentation into one paved path per real operator or developer goal.

    A production chain is a 24/7 operation: a HA sequencer
    cluster, sound withdrawal system, consistent L1 endpoints, secured hot
    keys, and robust operations. If
    you'd rather not run it yourself, or want OP Labs engineering behind the
    parts you do run,{" "}

    offers fully managed and supported self-managed options.

Each page in this section is a **solution guide**: one goal that in practice
spans several components, sequenced as a single in-site path. A solution
guide links each stop to its canonical page and states what to take from it,
adds the decision logic that no single component page can own, and leaves
the site only through curated, working exits. If your goal is listed here,
start here instead of assembling the path yourself.

  <Card title="Tune batcher costs" href="/use-cases/tune-batcher-costs">

  <Card title="Run a fault-proof challenger" href="/use-cases/run-a-fault-proof-challenger">
    Stand up an op-challenger that defends your chain, from bond budgeting
    through configuration and monitoring.

  <Card title="Implement a custom deposit flow" href="/use-cases/implement-a-custom-deposit-flow">
    Build an L1 to L2 deposit path, choosing the right contract entry point
    and handling gas, aliasing, and failures.
  </Card>

  <Card title="Launch a chain with fault proofs and HA sequencing" href="/use-cases/launch-a-chain-with-fault-proofs-and-ha-sequencing">
    Take a chain to production with withdrawals secured by fault proofs and
