Sweeps
A sweep moves accrued fees out of the curve or hook and into the Pons Fee Escrow, where a recipient can claim them. Plouto cannot perform a sweep, cannot force one, and cannot predict when one will happen.
This is the most significant external dependency in the design.
Who can sweep
| Operation | Caller | Where |
|---|---|---|
sweepPoolFees(poolId, minQuoteOut, minTokensOut) | Pons feeSweepOperator | Meme hook |
rescuePoolFees(poolId) | Pons-permissioned | Meme hook |
rescueCurveFees(token) | Pons factory owner | Factory |
None of these is callable by Plouto or by a Plouto role.
What the delay means in practice
- Revenue is earned but unavailable
Fees exist and are owed. They cannot be claimed, split, spent on buybacks or paid to stakers until the sweep happens.
- Rewards are lumpy
Stakers do not receive a smooth stream. They receive whatever arrives when a sweep lands and the router is called.
- A long gap looks like nothing happening
From the outside, an unswept period is indistinguishable from a period with no trading. The distinction is not visible on chain from Plouto's side.
Post-graduation this gets worse
Hook fees may be held in the memecoin rather than in ETH. Converting them to the quote asset happens during the sweep, and sweepPoolFees takes slippage parameters — meaning the operator must choose them sensibly for the sweep to succeed.
If the operator stops running, or runs with parameters that cause reverts, fees accumulate indefinitely.
What Plouto does about it
Three things, all of them honesty rather than mitigation:
- Unswept fees are shown as unknown, never estimated. See fee accrual.
- Claiming is permissionless, so the moment a sweep lands anyone can pull the fees — no Plouto operator needs to be awake.
- The dependency is documented here, in the threat model, and in Pons dependency.
Monitoring
pnpm keeper:route prints the escrow balance every run. A rising escrow balance means sweeps are happening; a flat one at zero means either no trading or no sweeping, and the two cannot be distinguished from Plouto's side.
The status page shows the same figure live under Fees credited in escrow.
