SurplusSplitter

API reference: SurplusSplitter · TareEngine · sTARE

ELI5: When TARE surplus is skimmed, this contract splits it — most to savers (sTARE), a slice to Keep for reinvestment.

What you can do

Function	Effect
split / skim hooks	Route surplus per configured bps
View params	senior_bps, emission_bps

FLYWHEEL 2.0: emission slice → Keep vault (not veForge).

Flywheel fit

Closes reinvestment loop: TARE revenue → Keep → CoilMakerStrategy → more fees.

Contract walkthrough

SurplusSplitter.vy:

• Senior bps (≥70%): TARE to sTARE vault
• Emission bps (≤30%): TARE to Keep / CoilMaker path

Only moves surplus already in engine or released — respects invariant.

What can go wrong

Risks

• Misconfigured bps → wrong yield split (governance/owner risk).
• Does not create surplus — only routes existing surplus.

Deep dive: FLYWHEEL 1.0 → 2.0

Emission slice previously targeted veForge emissions; 2.0 redirects to Keep for Coil market-making reinvestment.
