DeFi breaks on accounting, not ambition. Fixed-point discipline, oracle deviation bands, slippage and deadline guards, and emergency pause design — with staking-rewards math worked through line by line.

The guarded rollout

  • Fork simulation — mainnet state, adversarial sequences, worst-case receives.
  • Capped launch — limits small enough to survive surprise.
  • Monitored raises — caps rise only when reconciliation and support load read green.
  • Full open — with pause drills completed and signers rehearsed.

Exactness is a process, not a property. Build the process and positions stay exact.
