Metavault.Trade- The Solution For Trading Without Price Impact
The shortcomings of centralized exchanges are well-documented. They require an intermediary for order book management and execution, are exposed to various security risks such as the retention of private keys, and ultimately are slower and more expensive than a DEX. However, one particularly useful feature of their design is the CLOB model, which lets users transparently match their orders with one another on a “price-time-priority-basis.” In short, the highest bid and the lowest ask converge to represent the current market price, and users have the option to cross this bid-ask spread to immediately execute the order. Given the transparency of this system, users can see market depth in real-time. While these features of a CLOB are quite powerful, they are difficult to implement within an on-chain system. This difficulty stems primarily from high throughput and low execution cost requirements of an order book. That is, in order for a CLOB to effectively operate on-chain, gas fees must be cheap and transactions must be very fast.
Many of the first DEX protocols recognized these challenges and attempted to replace the traditional CLOB model through the implementation of an AMM. Uniswap pioneered this approach, and under their AMM system, DeFi users were able to quickly execute trades at a very low cost. However, several core functions of an order book, such as limit orders, bids, and offers were missing. In addition, liquidity providers were required to provide liquidity to both sides, were not able to choose to only provide liquidity at a particular price, and could not provide liquidity at a price other than the current market price. So the benefits of an AMM model come with certain tradeoffs.
Metavault.trade has developed a fully decentralized, on-chain order book that allows users to execute orders directly with a smart contract while still enabling flexibility with pricing and order sizes. Its CLOB and matching engine provides both liquidity and price-time-priority-basis matching to users, enabling them to choose the price, size, and direction of their trades just as they would when interfacing with a traditional CLOB, but without all of the associated inefficiencies.
Metavault.Trade launched on Polygon and will expand to more chains in the future.
The assets supported at launch on Polygon are six large caps and three stablecoins:
- BTC, ETH, MATIC, LINK, UNI, AAVE
- USDC, DAI, USDT
- Polygon transactions are fast and cheap.
- It’s easy to onboard users thanks to on-ramp / off-ramp from exchanges.
