How Sei Works
Sei is a layer 1 blockchain designed specifically for decentralized finance (DeFi) applications. It aims to provide a high-performance infrastructure tailored for trading and financial use cases.
The project utilizes a parallelized Ethereum Virtual Machine (EVM) to optimize for speed and scalability. This allows it to process transactions in parallel rather than sequentially, improving throughput and efficiency.
What Moves the Sei Price
Sei's price is influenced by its adoption within the DeFi ecosystem, particularly among traders and developers seeking faster and more efficient transaction processing.
The project benefits from its backing by prominent investors like Coinbase Ventures and Multicoin Capital, which can drive interest and investment.
As a layer 1 blockchain, its success depends on attracting developers to build applications on its platform, which in turn depends on its performance and ease of use compared to other blockchains.
Market conditions in the broader cryptocurrency space, especially those affecting DeFi and layer 1 blockchains, will impact investor sentiment and demand for SEI.
Regulatory developments could also play a role, particularly if they affect the DeFi sector or blockchain technology in general.
Sei Tokenomics & Supply
Sei has a circulating supply of 6,733,333,333 SEI with no fixed maximum supply, and a total supply of 10,000,000,000 SEI. Its fully diluted valuation is R$3.73B.
Sei has no fixed maximum supply, so new SEI can continue to be issued — its supply model is inflationary rather than capped. Current total supply is 10,000,000,000 SEI, of which 6,733,333,333 is circulating. Watch the issuance/burn rate rather than a hard cap to judge future dilution.
Its fully-diluted valuation is R$3.73B ($741.10M) versus a R$2.10B ($416.42M) market cap.
