Why Sei’s parallelized EVM and sub-second finality matter now

The migration to an EVM-only architecture

The migration to an EVM-only architecture removes the barrier to entry for developers who prefer using ubiquitous tools like MetaMask, Hardhat, and Solidity instead of learning the complex and specialized Cosmos-specific programming languages required for the original architecture. This transition, which moved the network away from its Cosmos-based layer, allows developers to port applications without modification. The Giga upgrade supports this shift through the Ares execution engine and the Eidos storage engine. Ares aims for a 10x throughput increase, while Eidos replaces Merkle trees with a flat key-value store. These components work to reach the target of 200,000 transactions per second and 5 gigagas per second of throughput. Sei provides 400ms block times, which is 30 times faster than Ethereum. The network uses a parallelized execution engine that processes transactions simultaneously to eliminate bottlenecks. This parallelized execution engine uses an optimistic model that assumes transaction independence and only re-executes specific conflicting transactions sequentially. To achieve this, the Twin-Turbo consensus utilizes Intelligent Block Propagation and Optimistic Block Processing. Intelligent Block Propagation allows proposers to transmit a proposal containing only a hash for each transaction, which validators then reconstruct using their local mempool. Optimistic Block Processing allows validators to process state changes as soon as they receive a block proposal.

Institutional infrastructure and the Giga roadmap

Institutional support for Sei follows partnerships with Jump Crypto and Crypto.com. Crypto.com provides a regulated, cold storage solution for the SEI token. Bhutan deployed a Sei Network validator in the first quarter of 2026 through a collaboration with Druk Holding and Investments. This collaboration expands the global validator footprint and supports projects in payments and finance. Xiaomi also integrates a native Sei wallet on millions of devices to enable peer-to-peer payments. You probably already know that institutional interest follows these types of validator and hardware partnerships. The Giga roadmap includes the Autobahn consensus, which uses a multi-proposer architecture to allow validators to propose transactions in parallel lanes. This architecture helps reach the target of 200,000 transactions per second. In this system, validators vote on data availability using compact cryptographic proofs rather than downloading full blocks. Will the Autobahn consensus deliver the 200,000 TPS target on the mainnet?

Performance targets and market competition

Sei competes with high-performance chains like Solana, Monad, and Aptos. While Sei claims 200,000 transactions per second on its internal devnet, the network has not yet proven these throughput levels under live economic activity on the mainnet. The network saw a TVL exceeding $1 billion in June 2025, but current stablecoin capitalization sits at approximately $306.96 million. Within that stablecoin supply, USDY accounts for 84.38% of the total. The network also recorded $85.65 million in 24-hour volume and a 98.68% increase in futures open interest over 30 days. The SEI token has a fixed total supply of 10 billion tokens. The ecosystem reserve receives 48% of this supply, while the core team and contributors receive 20%. The network also allocates 20% to investors and 3% to community programs. Current usage includes platforms like DragonSwap and Yei Finance, with Yei Finance holding over 60% of the DeFi TVL. The network supports gaming projects like World of Dypians and Archer Hunter, which saw a 79% spike in activity in Q1 2025. The SEI price sits at $0.07341, which is 93.56% below the all-time high, while direct protocol monetization stays low because chain fees reached only $94 in a 24-hour period. Staking SEI tokens requires a 21-day unbonding period before users can access their funds.
