SEI Smart Contract – Blockchain Security

SEI Smart Contract

Cross-chain topics continue to fill our narrative airwaves. Will there be a clear leader of cross-chain solutions in the cryptocurrency market, or will a powerful interaction infrastructure be built? SEI Network is well aware of the community’s fundamental importance for the project’s development; therefore, recruitment for the project’s ambassadors is open.

This year the Cosmos ecosystem shows a brilliant pace of development. Blockchain internet protocol and highly scalable, fault-tolerant POS are doing their job and attracting developers to the next generation of the ecosystem. SEI Network can boast of this, including these developments and its upgrades and adaptations for the uniqueness of its L1 solution.

SEI technology makes sense in principle and can change the whole way financial services operate.

SEI Shot Review

Most layer 1s fall into two extremes. On the one hand, these are general-purpose circuits like Solana or Ether, and on the other hand, these are application-oriented circuits. SEI opens up a design space between these two chains for specific use cases, allowing you to create an environment specifically for DEX applications.

This technology and interaction with smart contracts set SEI apart from the competition or Tendermint Core while focusing on security, reliability, and throughput, which allows you to create a completely new DeFi product.

Therefore, SEI aims to become the best first-level blockchain for DeFi applications. How do they do it? They embed order-matching technology into the chain itself, and every application built on top of it can use it.

SEI technology makes sense in principle and can change the whole way financial services operate. The mission of SEI is to create the best DeFi infrastructure.

Sei Features

SEI has carefully chosen a unique set of trade-offs that make tier 1 the optimal environment for DeFi applications. Designed from the bottom up to scale with DeFi needs, SEi opens up new possibilities through optimizations, including:

  • Built-in order book and shared liquidity hub
  • SEI – the fastest chain, before the completion of the transaction in ~ 600 ms
  • Single Compatibility – All applications are built on the same blockchain
  • Social Coordination
  • Insistency of chains around one application
  • Multichain Compatibility

SEI is currently validating a testnet of 250 validators divided into five groups. The mainnet will launch with 50 validators. However, this number may change depending on the final results.

SEI reports that the current block time is around 0.9 seconds, making them the fastest Cosmos SDK network to date if the figure is kept on the mainnet.

SEI Network Technologies and Differences

SEI focuses on reliability, security, and high throughput, creating a whole new echelon of ultra-high-performance DeFi products built on this network. SEI’s Central Order Book (CLOB) and Oracle data collection engine provide deep liquidity and price-time prioritization for traders and applications. Applications built on top of SEI benefit from a built-in order book infrastructure, high liquidity, and fully decentralized analysis service. Users benefit from this exchange model with the ability to choose the price, size, and direction of their trades, combined with Maximum Retrievable Block Value protection. To improve performance, SEI uses two important mechanisms:

Combining orders

SEI uses two levels of order consolidation. In the first case, market makers can send multiple orders within a single transaction, reducing gas costs. The second level includes an order pooling algorithm: all orders for one market (for example, ATOM) are executed together by a smart contract, which leads to the initialization of only one virtual machine and an increase in throughput.


In a typical blockchain, orders are usually executed sequentially. SEI has implemented a parallel order system, which essentially allows the simultaneous distribution of orders for different markets (trading pairs).

DEX Module

SEI Network has an Oracle module to support asset exchange rate pricing for use by other modules and contracts. Order data analysis requires involvement as an Oracle to provide the most reliable and accurate asset valuation.

Smart Contracts

The built-in order book allows smart contracts to access general liquidity. SEI uses the wasmd module to make things easier for developers. This gives two benefits:

  • CosmWasm is used in many blockchains. It is a very stable library with no bugs and an extensive developer ecosystem.
  • CosmWasm was created to solve many development problems other ecosystems face. Easier than Solana development and offers better security guarantees than Solidity.

Partners and Finance SEI

The SEI announced a funding round led by Multicoin Capital, Coinbase Venture, Delphi Digital, HRT, FlowTraders, and Kronos. The team says the new capital will be used to support the project as it approaches mainnet launch and further develops the more than 20 centralized applications already built in the SEI ecosystem.

It is important to say that Multicoin Capital played an important role in the early growth of the Solana ecosystem, which made them reliable partners and gave a certain percentage of confidence in the project’s progress.


There is currently no public information on the tokenomics of the SEI token. We expect the team to share these details soon because the information is missing, making it very difficult to predict something. But as with any project, we expect a new token, a new player in the market, and an influx of new customers for a fresh product.


SEI joins the growing DEX group with an exchange stack on Cosmos. Unlike the DeFi space on Ethereum, Cosmos developers are moving away from the AMM DEX trend and instead focusing on creating a decentralized trading experience similar to what centralized TradFi exchanges typically offer. This, along with the growing number of real-yield-focused protocols, could be the catalyst for the entire Cosmos ecosystem. SEI plans to benefit from a high-performance exchange-priority blockchain at its core. Thanks to this, we can conclude that new developments can be expected from the team, and the development of tokenomics is very soon.


What is SEI?

SEI is a first-level blockchain with a built-in limit order book. Sei serves as the infrastructure and common liquidity hub for DeFi applications.

What is a DEX module?

Allows smart contracts to use a basic order matching mechanism to easily and quickly create new markets.

How promising is the SEI?

It’s hard to say since the community is just forming around this project. Still, funding and partnerships with industry giants like Multicoin Capital and Coinbase Venture give hope for the development and competitiveness of SEI.
