Sei Support

We’re excited to announce that the Sei blockchain is now fully integrated as a Tier-1 blockchain within the Wallet-as-a-Service platform of Dfns. This integration expands our ecosystem of partners and delivers enhanced functionality for developers and users using the Sei blockchain, opening up new opportunities for decentralized finance (DeFi) and appchain integration.

What is the Sei blockchain?

Sei is a Layer 1 blockchain built on Cosmos, designed for decentralized exchanges (DEXs) and high-performance financial apps. It addresses common issues like front-running and transaction delays that affect decentralized markets. Sei provides institutional-grade infrastructure, including:

• High Throughput: Fast transaction processing with low latency, ideal for high-volume trading.
• Parallelized Order Matching: An innovative engine that processes trades in parallel, speeding up transactions.
• Fast Finality: Transactions are confirmed quickly and reliably.

Sei is more than just fast, it’s tailored for decentralized trading. Its built-in order matching engine, with features like order bundling and frequent batch auctions, optimizes trade execution, while front-running prevention ensures fair trading. For developers, Sei offers tools to easily build fast, scalable DeFi apps. 

As part of the Cosmos ecosystem, Sei benefits from the Inter-Blockchain Communication (IBC) protocol for seamless interaction with other blockchains. But Sei has also been working on Ethereum Virtual Machine (EVM) compatibility for a while now, enabling developers to bring Ethereum-based apps to its network. This integration expands the platform’s capabilities and user base, supporting more DeFi applications and accelerating ecosystem growth.

Dfns unlocks tier-1 status for Sei

Our Tier-1 integration with Sei offers full wallet and transaction features via Dfns, including:

• Automatic Asset Detection: Wallets automatically show SEI tokens, removing the need for manual updates and making it easier to manage portfolios.
• On-Chain Transfer History: Complete tracking of transaction history for assets within the Sei ecosystem, ensuring transparency and simplifying record-keeping and audits.
• Transaction Management: Securely generate signatures, transfer assets or broadcast transactions all through one wallet interface.
• Webhook Notifications: Get real-time alerts for balance changes and transaction updates, helping dApps and blockchain services respond quickly and efficiently.

By supporting Sei as a Tier-1 blockchain, Dfns provides developer teams, financial institutions and users with secure and compliant wallets, especially useful for DeFi markets and high-level trading, but also for use cases related to payments, banking, tokenization, and other financial services.

Cosmos SDK and appchain support

To integrate Sei, we developed a Cosmos SDK that extends our wallet platform to support other Cosmos appchains. Cosmos lets developers build blockchains (appchains) for specific use cases like trading, payments, and banking. The SDK is designed for SEI assets, but it can also allow any ECDSA key to work across all Cosmos appchains. This will give users more flexibility in key management and allow easy transitions between appchains without compromising security. Projects on MANTRA, Osmosis, Juno, dYdX, and other appchains will get the same strong wallet features that Sei users enjoy.
