## Good for

- appchains
- custom gas tokens
- dedicated throughput
- gaming chains

## Avoid for

- small apps that only need a contract
- teams without infra operations

## Capabilities

### Launch custom L2 or L3 chain (production-ready)
Best for: dedicated appchains, custom fee markets, chain-level control
- Requires sequencer, bridge, RPC, and ecosystem operations planning.

### Orbit SDK deployment workflow (production-ready)
Best for: scripted chain deployment, repeatable devnet and testnet setup
- Automation still requires infra and operating model decisions outside the SDK.

### Rollup and AnyTrust chain configuration (production-ready)
Best for: choosing data availability and settlement tradeoffs, customizing chain economics
- Mode selection affects cost, trust assumptions, and operating requirements.

### Custom gas token support (production-ready)
Best for: ecosystem-specific fee tokens, game or appchain economies
- Token economics and liquidity planning remain application-specific.

### Appchain operations planning (production-ready)
Best for: sequencer, RPC, bridge, monitoring, and upgrade planning
- Operational readiness depends on partner selection and team capability.

## Composes with

- **hyperlane** (interoperability; supports) — Hyperlane can provide cross-chain messaging and token routes for Orbit chains.
- **goldsky** (indexing_and_data; supports) — Goldsky can provide managed indexing and real-time data APIs for appchain activity.
- **safe** (operational_controls; supports) — Safe can manage chain operations, treasury, admin controls, and incident response for appchain teams.
