EthCC | SUSHI developer Joseph Delong introduces the next generation AMM: Trident

At the EthCC Ethereum Community Conference on the 20th, SushiSwap developer Joseph Delong announced a new generation of AMM: Trident.

It has many features, here are some key points:

• The new generation AMM, Trident, will bring the best efficiency for capital
• Trident will serve as a native application on the BentoBox platform
• BentoBox is the underlying layer that allows tokens to be put into financial strategies to achieve capital efficiency
• SushiSwap's liquidity will enter BentoBox, making over $2 billion in assets available for financial strategy utilization, and SushiSwap will become the largest interest rate aggregator
• Trident has four pools: three new pools and one traditional 50/50 token pair
• Trident will have its own version of centralized liquidity, concentrate liquidity
• There is a new pool called hybrid, which is suitable for tokens like USDT, USDC, RenBTC, WBTC, and it has no admission mechanism, allowing you to create liquidity pools for up to 32 assets
• Liquidity pools will have a 15% gas fee efficiency optimization
• Tines: routing engine, can find the best trade among the four pools, reducing slippage

Trident's Four New Liquidity Pools

• Constant Product Pool: The Constant Product Pool, a 50/50 pool where liquidity providers contribute 50% of token X and 50% of token Y, is a familiar pool for users. Its pricing curve follows the classic x*y=k constant product formula.
• Hybrid Pool: The Hybrid Pool allows users to use stableswap curves to reduce price impact, making it suitable for exchanging similar assets. Up to 32 assets can be configured in a Hybrid Pool.
• Concentrated Liquidity Pool: The Concentrated Liquidity Pool enables users to specify the price range of tokens X and Y when providing liquidity, maximizing trading fee revenue.
• Weighted Pool: Similar to the Constant Product Pool, the Weighted Pool allows custom weights. While the Constant Product Pool has a 50/50 weight for tokens X and Y, the Weighted Pool supports setting any weight, reducing price impact on the pool through custom weight settings.

All four pools can customize transaction fees.

Tines: Routing Engine

Tines is a newly designed frontend routing engine, an efficient multihop, multiroute exchange router. Tines queries various pools, considering factors such as gas cost, price impact, and graph topology to find the best price.

• Multihop: Tines facilitates exchanges across multiple pools to find the best price.
• Multiroute: Tines horizontally distributes trades to reduce price impact (slippage).

In essence, it helps users find the best trading price within the platform.

Next Goals: Compliance, Storage Proof

After launching Trident, SushiSwap has further plans:

• Franchise Pools: Franchise Pools allow institutions to provide liquidity on decentralized exchanges while meeting compliance requirements. These pools will be distinct from the main Trident AMM, where institutions can set liquidity providers and traders on a whitelist.
• Storage Proof TWAP: Trident will allow two concurrent (cumulative price) snapshots to be displayed in a single storage proof. To achieve this, users of TWAP prices need to submit a Merkle proof within the latest 256 block heights. On-chain, smart contracts will verify the validity of the storage proof and values to allow real-time TWAP snapshots. Kashi, deployed on Polygon, is a new implementation. We are also developing a low gas fee version to be deployed on Ethereum later.
