Fireblocks Broadens Institutional Reach to 150 Public Blockchains

Digital asset infrastructure provider Fireblocks has expanded its platform to support 150 public blockchains following the integration of 46 additional networks over the course of 2025. The move positions the company as one of the most extensive institutional access points to the increasingly complex multi-chain ecosystem. With the blockchain sector continuing to diversify, Fireblocks is aiming to simplify access for financial institutions that want exposure to new networks without rebuilding custody and transaction infrastructure each time a new chain gains traction.

The company’s expansion strategy is built around the idea that institutional players prefer a single integration that unlocks access to a wide range of blockchains. As new layer-1 and application-specific networks continue to emerge, Fireblocks is attempting to reduce operational friction by offering broad coverage through a unified platform.

Strategic Network Additions in 2025

Among the newly supported networks are several that hold particular relevance for institutional use cases. Canton was added as a privacy-focused blockchain designed to meet the needs of regulated financial institutions managing tokenized assets. Its architecture emphasizes confidentiality while maintaining compliance, making it attractive for enterprise and financial market participants.

Sui was also included, reflecting growing interest in blockchains that support parallel transaction execution. This feature has drawn decentralized finance developers seeking faster processing times and lower latency. HyperEVM was another notable addition, as it provides direct connectivity to Hyperliquid, a derivatives-focused decentralized exchange that has seen high levels of trading activity. This integration is especially relevant for trading desks and market makers engaged in perpetual futures strategies.

The expansion also brought support for Circle’s Arc Testnet, which enables transaction fees to be paid directly in USDC rather than native blockchain tokens. This capability is seen as a practical improvement for payments-focused institutions, as it reduces operational complexity and foreign token exposure.

Beyond these headline additions, Fireblocks integrated a broad mix of emerging and specialized networks, including those targeting gaming, real-world asset tokenization, and next-generation decentralized applications. While not all of these chains are expected to achieve long-term relevance, institutional clients benefit from having access without needing to predict which ecosystems will ultimately succeed.

Infrastructure Upgrades Supporting Scale

Fireblocks has indicated that scaling support to 150 blockchains required significant internal infrastructure upgrades. The company reported rebuilding core systems using a multi-node architecture supported by automated failover and self-recovery mechanisms. These changes were intended to maintain transaction reliability and throughput as the number of supported networks increased. The firm also noted improvements in overall latency, although it did not publish specific performance benchmarks.

The company’s focus on security and resilience traces back to its founding in 2018, which followed an investigation into a major Bitcoin theft. That experience influenced Fireblocks’ use of multi-party computation as a foundation for its custody and transaction security model.

Institutional Adoption and Broader Strategy

Fireblocks has raised more than $1 billion in funding to date, including a major round in early 2022 that valued the company at $8 billion. Its client base includes major financial institutions and global payment firms, suggesting that institutional adoption of digital asset infrastructure is continuing to progress.

Broad multi-chain coverage provides institutions with flexibility. When a specific blockchain becomes relevant for a new asset class or market opportunity, firms with existing access can move quickly rather than spending time and resources on new integrations. This optionality is increasingly important as blockchain innovation accelerates.

The company’s broader ambitions extend beyond custody and transaction management. The launch of its Global Stablecoin Payments Network in late 2025, covering more than 100 countries and dozens of currencies, indicates a growing focus on cross-border settlement and payment infrastructure.

While it remains uncertain how many of the 150 supported blockchains will attract sustained institutional capital, platform breadth is becoming a baseline requirement for infrastructure providers. For trading desks and financial institutions evaluating long-term partners, Fireblocks’ expanding network support reflects a bet that comprehensive access will be essential as digital asset markets continue to evolve.
