Fireblocks has officially launched support for the Sui, the blockchain built for mass adoption, enabling institutional clients to securely custody SUI assets and access the growing range of applications built on the network via WalletConnect. Sui joins the expanding list of blockchains supported by Fireblocks, reinforcing our commitment to bring our customers the ability to participate in the industry’s most exciting protocols.
Expanding Secure Access—Without Rebuilding Infrastructure
Fireblocks is built to scale as crypto ecosystems grow. Our platform provides a consistent security and governance layer across blockchains, allowing institutions to adopt emerging networks like Sui without introducing new operational risk.
With Fireblocks’ Sui integration, institutions can:
- Custody SUI and Sui-based tokens using MPC-based wallets with policy control
- Securely transfer SUI within the Fireblocks Network and to connected exchanges via our native integrations.
- Access Sui DeFi protocols via WalletConnect (coming soon)
- Prepare for staking through Fireblocks Trust (in development and approval phase)
These capabilities are available with zero new infrastructure lift for customers already on Fireblocks.
Meeting Customers Where They’re Headed
We prioritized support for Sui based on direct customer demand. Institutions, investment funds, fintechs, web2 gaming studios and infrastructure providers see strong potential in Sui’s high-throughput design and suitability for:
- Payments
- Trading
- Tokenized asset issuance
Sui’s ecosystem is strong, with stats to prove it, including over $1.7B in TVL, ranking 9th among all chains, and Sui’s 30-day DEX volume at over $8.1B, 8th amongst all blockchains in June 2025. After establishing clear product-market fit across multiple DeFi verticals, institutional interest in the Layer 1 has swelled since Q4 of last year. Institutions such as Grayscale, Franklin Templeton, and VanEck are already building on the network, while 21Shares and Canary Capital both recently filed with the SEC to issue SUI ETFs.
Fireblocks enables institutions to adopt Sui confidently—with secure custody, risk controls, and a production-grade platform.
