Zomma Protocol Review 2026: On-Chain Options on zkSync

Zomma Protocol is a decentralized options platform that launched on zkSync Era and later added an Arbitrum app. DefiLlama has tracked it since May 2023 under the Options category. It presents itself as an options protocol with high capital efficiency that brings traditional options features on chain.

The product centers on European-style calls and puts, traded with cross margin. The project highlights tight spreads and the ability to pay gas in USDC or other ERC-20 tokens on zkSync. It also describes plans for staking, yield mining and settlement products.

The team section lists co-founders who previously co-founded the JOYSO exchange, plus a chief scientist who is a university mathematics and quantitative finance academic and a strategist with a long derivatives trading background. These are the project's own claims. The homepage lists ecosystem partners including Syncswap, Perpetual Protocol and ZKsync.

Activity looks small. DefiLlama shows about $80,000 in TVL and a flat seven-day change, and the homepage footer is dated 2023-2024. Anyone considering it should check recent activity in the app and docs first.

Zomma is an on-chain options protocol. Traders buy or sell call and put options, which are contracts that give the right to buy or sell an asset at a set price on a set date. The options are European-style, meaning they settle at expiry rather than at any time before.

The project says it combines traditional options features with DeFi mechanics, including cross margin, where a single pool of collateral backs several positions. It claims this keeps collateral requirements minimal and capital efficiency high. The detailed pricing and liquidity model is described in the docs rather than on the homepage.

The protocol runs smart contracts on zkSync Era and Arbitrum. On zkSync, a paymaster integration lets users pay gas in tokens other than ETH. The roadmap also names staking and yield mining alongside options trading.

The homepage does not publish a fee schedule. It states that the protocol offers minimal call and put spreads, but gives no figures for trading, settlement or exercise fees.

Beyond protocol charges, users pay network gas on zkSync Era or Arbitrum. On zkSync, gas can be paid in USDC, Hold or other ERC-20 tokens through the paymaster. Exact costs are shown in the app and in the docs before you confirm a trade.

DefiLlama lists two audits for the protocol, and the homepage says an audit was completed, but its homepage does not name the auditors or link the reports. Review them in the docs before depositing. Smart-contract risk remains for any options protocol, including pricing errors, liquidation logic and oracle dependence.

Users keep funds in their own wallets and interact through smart contracts, so there is no centralized custodian, but collateral locked in the protocol is exposed to contract bugs. Regulatory status is not stated. The team's identities are published, which is a plus for accountability. The very low TVL and 2023-2024 copyright suggest limited recent activity, so confirm the app is still operating before using it.

Zomma is aimed at traders who already understand options and want on-chain exposure on layer-2 networks. It is less suited to beginners, to anyone who needs deep liquidity, or to users who want a protocol with clearly published fees and recent activity.
