Ostium · interactive mechanism simulation

Traders open synthetic RWA perps priced by an oracle signer → PnL settles against the Liquidity Buffer first, then the public OLP vault. Try compromising the oracle key.

Illustrative simulation. Defaults mirror the researched Ostium mechanism (two-tier liquidity: buffer absorbs routine PnL, OLP vault as backstop, custom RWA oracle feeds), but trade sizes and timing are randomized for visualization — not live onchain data. The failure button reenacts the July 2026 exploit where a compromised oracle signer key authorized fabricated future-dated prices, draining the vault in minutes. Part of The Onchain Experiment Atlas.
