Safe · interactive mechanism simulation

Owners sign transactions off-chain → the Safe proxy tallies signatures against a threshold → once k-of-n is met it delegatecalls the singleton to execute, passing through an optional guard. Try compromising the frontend to see why the Bybit hack bypassed none of this.

Illustrative simulation. Models Safe's k-of-n signature threshold, singleton delegatecall verification, and optional transaction guard; the "compromise" button illustrates how a breached signing frontend (as in the Feb 2025 Bybit theft) can get real owners to blind-sign a malicious payload the guard may not catch — the contracts were never exploited. Timing and amounts are randomized for visualization — not live onchain data. Part of The Onchain Experiment Atlas.
