Sei Network: Bringing High Throughput Decentralized Blockspace to Millions of Developers
Today, we're excited to announce that Alchemy infrastructure is now available on Sei Network, bringing together two builder-obsessed teams to deliver parallel transaction processing so you can build your biggest ideas.
Why This Partnership Matters
For developers who've been held back by blockchain's technical limitations, this partnership delivers a powerful combination: Sei's high-performance parallel execution model paired with Alchemy's reliable infrastructure.
Sei stands out with its ability to process multiple transactions simultaneously, enabling unprecedented throughput without sacrificing decentralization. With the upcoming Giga upgrade, Sei will deliver an impressive 5 gigagas per second—50x more computational power than existing EVM chains.
Why Leading Chains Choose Alchemy
Sei Network's collaboration with Alchemy builds on our proven track record of empowering the most innovative blockchain ecosystems. Here's why performance-focused chains like Sei consistently select Alchemy as their infrastructure partner:
Unmatched Reliability: With enterprise-grade infrastructure trusted by thousands of developers, Alchemy delivers the stability needed for mission-critical applications.
Developer Experience Obsession: Our comprehensive tooling eliminates infrastructure headaches, allowing builders to focus on what matters—creating groundbreaking applications.
Ecosystem Acceleration: Chains partnering with Alchemy benefit from our extensive developer reach and proven ability to catalyze ecosystem growth.
Performance at Scale: Our infrastructure is built to handle explosive growth, supporting projects from prototype to global adoption without missing a beat.
What Builders Get
Starting today, you can build on Sei with Alchemy's Node API. Our integration brings you:
Reliable Node Infrastructure: Build with enterprise-grade stability
Reduced Development Time: Focus on creating rather than maintaining infrastructure
Seamless EVM Compatibility: Deploy existing Ethereum smart contracts without modifications
This is just the beginning. We're working to bring our full suite of developer tools to Sei, including Subgraphs, Token API, Transfers API, and Webhooks in the coming months.
Why Build on Sei?
Sei Network offers unique advantages for developers:
1. Unmatched Performance & Scalability: With the upcoming Giga upgrade delivering 5 gigagas per second, Sei provides 50x more computational power than existing EVM chains.
2. Seamless EVM Compatibility: Deploy existing Ethereum smart contracts without modifications, leveraging familiar tools while unlocking higher performance and lower fees.
3. Developer-First Infrastructure: Comprehensive documentation, technical resources, and milestone-based funding opportunities support builders at every stage.
The combination of Sei's performance capabilities with Alchemy's reliable infrastructure creates an environment where developers can finally build without compromise.
What This Means for Builders
This partnership removes technical limitations that have historically held back blockchain applications. Developers can now build applications that weren't previously possible onchain—high-frequency trading platforms, AI-driven protocols, and real-time games.
Whether you're building in DeFi, gaming, AI, or other verticals, the Alchemy + Sei combination provides the foundation you need to bring your most ambitious ideas to life.
The Giga Upgrade: Scaling the Future
The upcoming Giga upgrade represents a major leap forward for Sei, designed to unlock its full performance potential. With 5 gigagas per second and an optimized EVM client, Giga will scale Sei's throughput by 50x, enabling more complex, data-intensive applications to thrive.
Key highlights include:
Rebuilt EVM Client with ahead-of-time compilation for ultra-fast transactions
Revolutionary consensus with asynchronous execution to maximize throughput
Next-gen storage eliminating traditional state update bottlenecks
