# Sentora Curator Gas‑Efficiency Review: Unlocking $2.5 B TVL Savings

## Sentora Curator Gas‑Efficiency Review

Sentora Curator, a cross‑chain curation protocol with a total value locked of roughly $2.5 B, has undergone a detailed gas‑optimization audit. The audit, completed in late September 2026, focused on the most frequently executed contract paths—deposit, withdrawal, reward claim, and curator state updates—identifying opportunities to reduce transaction costs and enhance user experience on both Ethereum L1 and L2 roll‑ups.

## Key Findings

The audit revealed that several core functions operate well above industry gas benchmarks. Typical gas costs for major actions are:

- Deposit (ERC‑20): 115 k vs. an ideal 80 k (≈ 30 % higher)
- Withdraw (ERC‑20): 108 k vs. 75 k (≈ 30 % higher)
- Claim Rewards: 140 k vs. 95 k (≈ 32 % higher)
- Curator State Update (batch): 210 k vs. 130 k (≈ 38 % higher)
- Factory Deploy: 1 200 k vs. 950 k (≈ 21 % higher)

These inefficiencies translate into substantial cost savings: a 10 % reduction in gas for every transaction would save millions of dollars annually for users and the protocol.

## Primary Gas‑Cost Drivers

- Repeated storage reads/writes inside loops, especially for `curatorInfo` and `rewardInfo` structs.
- Unnecessary `address(this).balance` checks during ERC‑20 transfers.
- Redundant `require` statements that duplicate earlier validation steps.
- Inefficient handling of dynamic arrays that grow or shrink with each transaction.
- Missing `unchecked` blocks that could safely skip overflow checks for arithmetic operations in Solidity 0.8.x.

## Security Implications of Gas Overuse

Beyond cost, excessive gas can expose the protocol to denial‑of‑service attacks. Attack vectors such as unbounded loops in reward distribution allow malicious actors to inflate transaction sizes, causing higher gas consumption and potential front‑running. The audit identified specific functions—`claimRewards()`, governance‑controlled token arrays, and batch updates—that require careful handling to maintain economic safety.

> “Optimizing gas not only lowers fees but also hardens smart contracts against economically motivated exploits,” notes the audit team.

## Recommendations

- Introduce loop‑bounding limits for reward token enumeration.
- Replace `address(this).balance` checks with token‑specific balance validations.
- Consolidate `require` statements to eliminate redundancy.
- Pre‑allocate dynamic arrays or use storage slots efficiently to reduce per‑tx resizing.
- Apply `unchecked` blocks where arithmetic is proven safe.

Implementing these changes would bring Sentora Curator’s gas profile in line with leading DeFi protocols, improve L2 competitiveness, and protect users from unnecessary fee exposure.
