Rehype Doppler Hook

When to use

• Tasks mention Rehype, buybacks, fee distribution, or claimAirlockOwnerFees

• You are working in src/dopplerHooks/RehypeDopplerHook.sol

• You are troubleshooting hook-driven swap behavior for pools managed through DopplerHookInitializer

Prerequisites

• Pool asset address

• Access to DopplerHookInitializer.getState(asset)

• Correct signer (buybackDst for fee distribution updates, airlock.owner() for owner-fee claims)

Core workflow

• Resolve pool context from initializer state and derive poolId .

• Read hook state:

• getFeeDistributionInfo(poolId)

• getHookFees(poolId)

• getPoolInfo(poolId)

• Apply operation:

• Update distribution with setFeeDistribution(...) from buybackDst

• Collect beneficiary-directed fees with collectFees(asset)

• Claim 5% owner fees with claimAirlockOwnerFees(asset) from airlock.owner()

• Validate storage resets and token balance deltas after each action.

Quick facts

Item Detail

Initializer integration Uses DopplerHookInitializer.getState(asset)

Distribution authority buybackDst only

Airlock owner fees Separate 5% bucket, claimable via claimAirlockOwnerFees

Primary tests test/integration/RehypeDopplerHook.t.sol

Failure modes

• Distribution does not sum to WAD

• Non-authorized caller for distribution update

• Non-owner caller for owner-fee claim

• Assuming hook fees equal transferable balances without checking internal buckets
