Sei has launched its own oracle to support exchange rate pricing for tradable blockchain assets. A unique mechanism for placing and sorting orders allows decentralized exchangers to operate on top of the Sei blockchain. The matching mechanism will provide the functionality. The system allows you to create both market and limit orders.

Orders from one market will be combined into a single contract and, thanks to the matching mechanism, they will all be executed within the block. However, the engine does not charge any fees at the base chain level at startup. This allows exchanges to independently regulate the size of the commission by setting fees at the smart contract level. More detailed information about how the ecosystem works is available at https://docs.sei.io.
