This week on DIN's highlight, we turn our attention to Sei, a high-performance Layer-1 blockchain built for parallelized execution, Ethereum compatibility, and scalability at Solana-level speed. This is currently live on MetaMask Developer Dashboard via Infura and decentralized by DIN.

Origin Story
Sei Network originally launched as a high-speed Cosmos-based chain focused on DeFi. But with most developers building in Solidity, Sei's team evolved the protocol to speak the language of the EVM. The result is Sei v2, an upgraded Layer-1 that embeds a fully-integrated Ethereum Virtual Machine inside the Sei core, all while preserving blazing-fast performance (~390ms finality). It marks the first EVM chain to support true parallel execution natively.
Tech Stack
Sei combines the Cosmos SDK with a Geth-based EVM, making it fully Ethereum-compatible. Core components include:
-
Parallel execution engine: Optimistically runs transactions in parallel, falling back to sequential execution on conflict.
-
Twin Turbo consensus: Optimized Tendermint variant tuned for sub-second block times.
-
SeiDB: A new storage model splitting state into a compact consensus-critical commitment and a full, fast-access store.
-
Integrated EVM: Solidity contracts deploy out-of-the-box using Ethereum tooling like Hardhat and MetaMask.
Feature Spotlight
-
First Parallelized EVM: No need for developers to annotate transactions—the network handles conflict detection and scheduling.
-
EVM + CosmWasm: Supports both Solidity and Rust contracts; enables cross-VM calls.
-
MEV-aware plugins: Validators can run customizable MEV strategies; extraction is transparent and auditable.
-
SeiDB: Nodes use 20x less storage and sync 10x faster than legacy Cosmos chains.
-
Native restaking integrations: Designed for AVS participation via EigenLayer and Symbiotic.
Ecosystem Overview
As of mid-2025:
-
Over 2 billion transactions processed.
-
$200M+ TVL across DeFi, NFT, and gaming dApps.
-
dApps like Vortex DEX, NFT marketplaces, and on-chain games live.
-
Sei's L2-compatible bridge supports USDC, swETH, and other cross-chain assets.
-
Builders have deployed via Gitcoin grants and the $50M Sei Ecosystem Fund.
Why DIN?
Sei v2's performance makes RPC a mission-critical component. DIN integration ensures:
-
High uptime via a federated network of providers.
-
Low latency thanks to geo-routed access.
-
Load balancing for 28K+ TPS workloads. This gives developers a resilient backend to match Sei's frontend speed.
Roadmap & Governance
-
Sei Giga upgrade will boost TPS to 250K with a new "Autobahn" consensus layer and fully parallelized VM.
-
Governance remains on-chain via SEI stakers, with grants, fee tuning, and upgrade approvals managed by community proposal.
-
The Sei Foundation and Labs support core dev, but validators and users shape long-term direction.
Community & Developer Onboarding
-
Sei supports all standard EVM tooling.
-
Devs can deploy with Hardhat, test with Foundry, or use Keplr for CosmWasm.
-
Grants available via Gitcoin and ecosystem fund.
-
Educational campaigns and "Accelathon" events foster new ideas and cross-chain collaborations.
