Crypto.com has unveiled a strategic collaboration with the Sei Network, a high-performance Layer 1 blockchain tailored for digital asset markets. Announced on September 19, 2025, this partnership aims to deliver institutional-grade custody solutions for the Sei Network’s native SEI token, addressing the growing demand for secure asset management in a fast-evolving ecosystem.
As more institutions explore regulated avenues into blockchain technology, this collaboration positions both Crypto.com and Sei Network at the forefront of scalable and compliant cryptocurrency infrastructure. Based in Singapore and founded in 2016, Crypto.com has built a substantial user base exceeding 100 million globally, offering a broad spectrum of financial services while emphasizing security and regulatory compliance.
Crypto.com Custody, the firm’s custody division, specializes in end-to-end solutions for eligible institutions and high-net-worth individuals. Its offerings include cold storage vaults, multi-signature protocols, and continuous monitoring to protect digital assets from cyber threats. With the integration of Sei, Crypto.com enhances its custody services to encompass SEI tokens, facilitating secure storage necessary for treasury operations, validator staking rewards, and wider participation in the Sei ecosystem.
At the heart of this integration is the Sei Network, an ultra-fast Layer 1 blockchain launched in 2023. The network has rapidly gained recognition as a dominant player in high-frequency trading and decentralized finance (DeFi) applications, distinguished by its parallelized Ethereum Virtual Machine (EVM) compatibility. This innovative feature empowers developers to create scalable decentralized applications with sub-second finality and throughputs that exceed 20,000 transactions per second. To date, Sei has processed billions of transactions across over 45 million wallets, receiving backing from prominent investors including Multicoin Capital, Jump Crypto, and Coinbase Ventures.
Sei is currently in the Devnet testing phase for its V3 Giga upgrade, a significant scaling initiative inspired by Ethereum’s ecosystem, aiming to manage even larger transaction volumes. The integration with Crypto.com enables seamless access to Sei’s rapid capabilities while ensuring a secure custody framework for institutional users. This allows institutions to deposit and manage SEI tokens in a regulated cold storage setting, mitigating risks common with hot wallets or self-custody options in volatile market conditions.
The new system promises to enhance low-latency operations critical for Sei’s use cases, such as decentralized exchanges and perpetual futures platforms, without sacrificing security. Validators and ecosystem developers stand to benefit from reliable asset management for rewards distribution, while treasury managers will gain access to compliance tools that align with global standards such as SOC 2 and ISO 27001.
Eric Anziani, Crypto.com’s President and Chief Operating Officer, articulated the partnership’s broader relevance, stating, “Institutional custody is a critical foundation for scaling blockchain ecosystems. We’re pleased to support the Sei Network’s mission to power high-frequency, low-latency applications with secure infrastructure that meets the highest standards of compliance and operational integrity.”
Justin Barlow, Executive Director at the Sei Development Foundation, voiced enthusiasm over the collaboration, noting, “We’re thrilled to see another leading provider of institutional-grade custody solutions choose to support the Sei Network. Through Crypto.com Custody, institutional investors will have yet another tool to interact with Sei in a secure and regulated way.”
This strategic partnership arrives during a crucial period for the cryptocurrency industry, marked by heightened regulatory scrutiny. Regulations such as the EU’s MiCA and U.S. SEC guidelines require enhanced custody standards, and by providing a compliant on-ramp, Crypto.com and Sei aim to reduce barriers for traditional finance players cautious about self-managed blockchain exposure. This could lead to faster adoption of SEI and increased liquidity and innovation within Sei’s DeFi hubs, such as Astroport and DragonSwap.
For Crypto.com, this move strengthens its competitive position against rivals like Coinbase Custody and Fireblocks, highlighting a trend toward specialized, network-agnostic custody solutions. Looking forward, the integration may inspire similar collaborations across Layer 1 chains, fostering a more interconnected landscape for institutional cryptocurrency investment.
As blockchain and distributed ledger technology initiatives transition from speculative ventures to foundational infrastructure, secure custody solutions remain critical. With Sei’s V3 Giga on the horizon, the crypto space anticipates heightened activity that could attract more capital and talent, further empowering the ecosystem’s growth.
