Hanji Protocol Review 2026: On-Chain Orderbook DEX

Hanji Protocol is a decentralised exchange built around an on-chain central limit order book. According to its DeFi listing, it runs on Etherlink, Base and Monad, and it describes itself as a CLOB DEX and prop-AMM. The site was listed in March 2025.

The pitch is trading conditions closer to a centralised exchange: 0% maker fees, low taker fees, and a matching engine designed to keep gas costs down. The homepage shows about $4.15 million in daily volume and about $378 million in cumulative volume, which are self-reported figures.

Total value locked is around $1.0 million, so the venue is small. There is no native token listed. The homepage includes an Audits section but does not name an auditor in the text, and the DeFi data lists no audits.

A central limit order book matches buy and sell orders at specific prices. Traders who post limit orders add liquidity to the book (makers), and traders who accept an existing price take liquidity (takers). Most DEXs use AMM pools instead, so an on-chain orderbook is a different design that gives traders control over price and order type.

Running an orderbook on-chain is gas-intensive, because each placement, cancellation and match changes stored data. Hanji says it uses radix trees to organise orders so matching cost grows logarithmically, and reuses storage slots from cancelled orders to cut costs.

For users who do not want to manage orders, LP vaults run automated market-making strategies. Depositors can choose single-token or multi-asset vaults and earn yield from the strategy. The DeFi data also calls Hanji a prop-AMM, which suggests that proactive market-making logic supplies liquidity alongside the book. Vault returns depend on market conditions and are not guaranteed.

Hanji advertises 0% maker fees, so placing limit orders that add liquidity to the book costs nothing in protocol fees. Taker fees are described as low, but its homepage does not give a specific percentage. Users should check the trading interface or documentation for the current rate.

On top of protocol fees, each trade or order action pays network gas on Etherlink, Base or Monad. Hanji says its storage optimisation reduces gas across operations, but actual costs depend on the chain and congestion. Vault fees, if any, are not stated.

Hanji is non-custodial in the usual DEX sense: users trade from their own wallets and interact with smart contracts. That means the main risks are smart-contract bugs, oracle or strategy failures in vaults, and the usual wallet and phishing risks. The homepage has an Audits heading but names no auditor, and the DeFi data lists zero audits, so users should look for audit reports in the official docs.

Hanji does not publish a team or legal entity in the text available beyond a credit saying the site was made by Relate. No incidents are reported in the information available. With TVL around $1 million, a small venue can have thin liquidity and be more exposed to price impact. Only deposit what you can afford to lose.

Hanji is best for active traders, market makers and DeFi users who prefer limit orders over pool swaps and are comfortable with smaller, newer venues. It is less suited to beginners who want simple swaps or users who require published audits and deep liquidity before trading.
