For vault & treasury strategies
DeFi vault rebalancing
Rebalance a strategy that holds positions on several rollups without ever routing treasury assets through a bridge vault.
A yield vault with legs on Optimism, Base, and Arbitrum has to move capital between rollups as APYs shift. Doing that through a bridge means the treasury spends part of every rebalance sitting inside a custodial lock contract — exactly the surface that has produced nine-figure exploits.
- 01
The rebalance is modelled as an atomic swap group: reduce on the over-weighted rollup, add on the under-weighted one, in one settlement.
- 02
Assets never enter a shared vault — they move native-to-native on each chain, so there is no honeypot balance for an attacker to drain.
- 03
If any leg cannot resolve inside the deadline, the whole rebalance refunds and the strategy is exactly where it started — no partial, stranded position.
- 04
Every leg routes a protocol fee through the on-chain FeeCollector, so cost is transparent and auditable rather than hidden in bridge spreads.
