## Assets

- [Sei (SEI)](https://thegrid.id/profiles/sei): SEI is the native token of Sei Network, a Layer 1 blockchain optimized for trading applications. It is used to pay transaction fees, stake with validators to secure the network through proof-of-stake consensus, participate in governance, and serve as collateral in applications. The token benefits from parallel transaction processing enabled by Optimistic Concurrency Control, which allows SEI-denominated transactions to settle in 400ms by executing non-conflicting operations simultaneously across multiple CPU cores. (Native)
