Multicurve Price Discovery Auction

Suggested profile

• Asset tier: low/medium-value assets
• Curve posture: predictable supply curves
• Governance: OpenZeppelin Governor: disabled
• Migration: none
• Hook path: DopplerHookInitializer + rehypothecation hook (RehypeDopplerHook)
• Beneficiaries: custom fee beneficiary setup
• Preallocation: 3 addresses
• Market posture: widely supported in production flows; commonly used by teams including Zora and Bankr

When to use

• You are configuring the default launch path for most assets
• You need curve share math and position distribution behavior
• You need deployment-mode semantics (non-migrating vs migrable/locked)

Prerequisites

• Decide governance mode as a product choice:
  • OpenZeppelin Governor: disabled (default)
  • OpenZeppelin Governor: enabled (only when token-holder governance is required)
• Use 3-5 supply curves for most launches
• Include a tail position from max-curve to infinity (SDK max keyword)
• Use scheduled multicurve by default with startingTime = 0
• Use decay multicurve only when you explicitly need fee decay behavior (startFee -> fee)
• Treat base multicurve as deprecated for new integrations (legacy support only)

Core workflow

1. Build Curve[] with 3-5 supply curves, including the max-tail curve to infinity.
2. Validate curve shares sum to WAD and all ticks align to tickSpacing.
3. Choose deployment mode:
   • Default: non-migrating launch path
   • Advanced: migrable/locked lifecycle paths when required
4. Configure hook initializer and module path (DopplerHookInitializer + rehypothecation hook RehypeDopplerHook) with beneficiary fee routing.
5. Initialize pool with scheduled multicurve (UniswapV4ScheduledMulticurveInitializer) and set startingTime = 0 unless delayed launch gating is intentional.
6. Verify lifecycle path, preallocation recipients, and claims flow for the chosen mode.

Quick facts

Item	Detail
Main contracts	UniswapV4ScheduledMulticurveInitializer (default), DecayMulticurveInitializer (conditional), UniswapV4MulticurveInitializer (legacy/deprecated for new integrations)
Allocation model	Shares-based across independent curves
Rebalancing	None (static positions)
Hook variants	Scheduled start-time hook, decay fee-schedule hook
Default posture	No governance, no migration, 3-5 curves + max tail + scheduled variant with startingTime = 0

Failure modes

• Curve shares not summing to WAD
• Missing max-tail position (max curve to infinity)
• Tick spacing misalignment
• Using base multicurve instead of scheduled multicurve for new integrations
• Setting nonzero startingTime unintentionally and delaying launch start
• Choosing migrable lifecycle when non-migrating posture is intended
• Wrong assumptions about scheduled start or decaying fee behavior
