Beyond Throughput: Performance and UX on Sei

Sei is accelerating forward, not just by scaling throughput, but by becoming the most performant and user-friendly Layer 1 blockchain for real-world applications.

In December 2024, Sei Labs published 'Giga: the Path to 50x Improvements on the EVM' a technical roadmap for scaling to 5 gigagas per second. This milestone represents a breakthrough in EVM-based performance, enabling applications to operate with Web2-level speed and efficiency. As part of this effort, Sei Labs successfully achieved 5 gigagas of throughput in an internal devnet using Autobahn, a new consensus protocol designed for high throughput and low latency in globally distributed validator networks.

But raw performance alone isn't enough.

If users can't onboard, access stable assets, or interact with protocols easily, performance won't matter. The gap between Web3's capabilities and user expectations remains wide and Sei Development Foundation is closing this gap through strategic ecosystem-level upgrades to the Sei network.

Creating a Better Web3 Experience

Three ecosystem-level upgrades have recently launched on Sei, led by teams building user-centric products that improve how people access, use, and navigate Web3.

Sei Global Wallet– Embedded Wallets That Just Work

Built by Dynamic, Sei Global Wallet transforms ecosystem access with a seamless, embedded experience. Users can sign in with familiar credentials (Email, Google, X, or Telegram) and access the same wallet across every integrated Sei dApp.

This eliminates the setup complexity that has kept mainstream users away from Web3, replacing it with login methods familiar to anyone who's used a modern application.

For users, this means:

• Simple, one-click access using familiar credentials.
• A single wallet that follows you across the Sei ecosystem.
• No onboarding friction, just sign in and go.

For developers, Sei Global Wallet delivers:

• Frictionless onboarding without directing users to external wallets
• Faster activation of new users, with fewer steps and drop-off points
• A seamless experience that works across all Sei dApps, by default

USDT0 – High-Speed, Unified Stablecoin Liquidity for Sei

Now live on Sei, USDT0 delivers deep, composable stablecoin liquidity to the network, enabling faster, more cost-efficient experiences across DeFi, payments, and beyond.

Built on LayerZero's OFT (Omnichain Fungible Token) standard, USDT0 is backed 1:1 by USDT enabling seamless cross-chain movement of stablecoin liquidity without traditional bridge dependencies.

For users, this means:

• Low-cost stablecoin transfers across chains
• Ability to redeem 1:1 with native USDT
• A better DeFi experience powered by fast execution and unified access

For developers, USDT0 offers:

• Deep, composable liquidity for Sei-based protocols
• Native integration that supports scalable user flows

Symphony – Onboarding and Trading, Streamlined

Symphony serves as both an entry point for new Sei users and a DEX aggregator that finds optimal trading routes. It provides guided onboarding flows that help users begin their Sei journey with clarity and confidence.

For users, Symphony offers:

• Clear, guided onboarding that shows exactly how to get started on Sei
• Accessibility for those with no prior crypto experience
• Smart trade routing that pulls in the best prices it sources from multiple liquidity pools

For developers, Symphony provides:

• Improved user retention through clear onboarding experiences
• Access to aggregated liquidity through Symphony's DEX routing
• A plug-and-play experience designed to complement any Sei dApp

Technical Performance Meets User Experience

These UX initiatives are designed to complement the upcoming performance breakthroughs of the Giga upgrade. Together, they align Sei’s technical scale with intuitive design, creating an environment where developers can build faster and users can onboard without friction.

Giga Upgrade performance on Devnet

The Giga upgrade includes:

• Execution improvements: A rebuilt EVM client optimized for speed, intelligent parallelization of non-conflicting transactions, and a new encoding format to minimize processing overhead
• Consensus enhancements: Powered by Autobahn, Sei’s next-generation hybrid consensus protocol designed for global scale. Autobahn enables asynchronous execution by decoupling transaction ordering from execution, introduces multiple concurrent proposers for better censorship resistance, and includes a highly efficient data propagation layer, all contributing to low-latency, high-throughput finality.
• Storage optimizations: Asynchronous state root generation, enhanced asynchronous disk writes with write-ahead logs, and an optimized key-value database for faster data retrieval

Building the Complete Web3 Stack

The Sei Development Foundation's vision extends beyond pure speed, it's about empowering your ideas to come to life onchain without limitations.

While the Giga upgrade removes technical barriers with unprecedented performance, these latest ecosystem developments eliminate UX friction, creating a complete stack where both builders and users can thrive without compromise.

There’s no better time to build on Sei than today.
