The SEI cryptocurrency has officially launched on OKJ, a licensed domestic crypto exchange in Japan, marking a significant milestone for both the platform and the Sei network. With this addition, OKJ now supports 46 different digital assets, expanding access for Japanese investors to one of the fastest-growing Layer 1 blockchains designed specifically for trading efficiency.
The deposit and withdrawal functionality for SEI will go live on July 8, 2025, at 17:00 JST, with full trading operations commencing on July 11, 2025, at 17:00 JST. Trading will be available through both the exchange service—where users interact via an order book—and the simplified instant buy/sell “sales counter” (販売所), catering to both experienced traders and newcomers alike.

What Is SEI Cryptocurrency?
SEI is the native token of Sei Network, a Layer 1 blockchain engineered for speed and scalability in digital asset trading. Unlike general-purpose blockchains, Sei is optimized specifically for decentralized exchanges (DEXs), trading platforms, lending markets, and NFT marketplaces—making it a powerful infrastructure choice for financial applications in Web3.
The network powers a growing ecosystem that includes major platforms such as MagicEden, one of the leading NFT marketplaces, which has deployed its services on Sei to leverage its high-throughput capabilities. Other DeFi protocols, including DEXs and lending protocols, are also building on Sei to deliver faster execution and lower latency.
As the foundational currency of the Sei ecosystem, SEI serves multiple critical functions:
- Paying transaction fees on the network
- Participating in staking to secure the blockchain and earn rewards
- Engaging in governance by voting on protocol upgrades and proposals
This multi-role utility ensures that demand for SEI grows alongside the expansion of its ecosystem—making it not just a speculative asset but a functional component of a live, working blockchain economy.
Who’s Behind the Sei Network?
Sei was co-founded by former executives from top-tier financial institutions, including Goldman Sachs and Robinhood Markets, blending traditional finance expertise with cutting-edge blockchain innovation. This unique background has helped position Sei at the intersection of institutional credibility and decentralized technology.
Their vision was clear: build a blockchain that doesn’t compromise on speed when it comes to executing trades. By integrating features like twin-turbo consensus and parallelized transaction processing, Sei achieves some of the fastest finality times in the industry—often under half a second.
This performance focus has attracted attention beyond the crypto-native community. Notably:
- The Wyoming Stablecoin Project in the U.S. has explored integration with Sei
- Canary Capital filed an application for a SEI-based ETF (Exchange Traded Fund) in the United States, signaling growing institutional interest
These developments underscore Sei’s potential to bridge decentralized finance with regulated financial markets—an increasingly valuable proposition as global regulators seek compliant frameworks for digital assets.
Why SEI Stands Out in the Layer 1 Landscape
While many Layer 1 blockchains aim for broad use cases, Sei differentiates itself through specialization. Think of it as a sports car built for the racetrack rather than an all-terrain vehicle. Here’s what sets it apart:
⚡ Ultra-Fast Transaction Finality
Sei leverages a novel consensus mechanism called Twin-Turbo Consensus, combining a leader-based voting system with a pre-consensus layer that reduces message complexity. The result? Faster block propagation and near-instant trade settlement.
📊 Order Matching Engine Built into the Blockchain
One of Sei’s most innovative features is its on-chain order matching engine, which allows decentralized exchanges to process trades directly at the protocol level—reducing reliance on off-chain infrastructure and improving transparency.
🔗 EVM and CosmWasm Compatibility
Developers can build on Sei using either Ethereum Virtual Machine (EVM) tools or CosmWasm smart contracts, giving them flexibility to deploy applications from both Ethereum and Cosmos ecosystems.
🌱 Growing Ecosystem Adoption
With platforms like MagicEden launching on Sei and new DeFi projects choosing it as their base layer, the network is rapidly gaining traction. Its developer grants program and startup incubators further fuel innovation within the ecosystem.
