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.

Tune batcher costs

Cut what your chain spends posting data to L1, and recover what you do spend through your fee parameters.

Run a fault-proof challenger

Stand up an op-challenger that defends your chain, from bond budgeting through configuration and monitoring.

Implement a custom deposit flow

Build an L1 to L2 deposit path, choosing the right contract entry point and handling gas, aliasing, and failures.

Launch a chain with fault proofs and HA sequencing

Take a chain to production with withdrawals secured by fault proofs and a sequencer cluster that survives node failures.

Choose your node stack

Pick the consensus and execution clients for a node based on the job it does, with review-dated support facts.
