Secure Storage & Reward Distribution Architecture

Autopilot uses a dedicated contract the RewardsVault to manage reward storage and distribution. All rewards, once converted to USDC, are held in this contract until claimed by users. The vault operates independently from voting logic and follows a strict on-chain accounting model.

Key Properties

Isolated Reward Storage The RewardsVault is separate from the contracts responsible for voting, claiming, and swapping. No external party — including the protocol team — has access to the funds.

Tracked Balances All USDC balances are recorded under:

solidityCopyEdittotal_tokens_stored

This allows the protocol to maintain accurate reward accounting across epochs.

Built-in Validation The contract includes a withdrawNonAccounted() function to resolve rare inconsistencies (e.g., incomplete swaps or edge-case rounding errors). This ensures the stored reward pool matches expected balances.

Proportional Limits User withdrawals are capped based on their voting share from the previous epoch. Claims are enforced using fixed formulas tied to veAERO vote weight, preventing overclaiming or manipulation.

The RewardsVault is a non-custodial rewards contract. Funds are allocated transparently, based on voting power, and can only be withdrawn by the rightful wallet.
