Institutional crypto custody just got a new on-ramp to Cardano. Fireblocks, one of the largest digital asset infrastructure providers in the space, has integrated its RAW signing technology with Iagon’s enterprise-grade Cardano nodes and Insights API, giving approved customers a fully operational method for interacting with ADA and Cardano Native Tokens (CNTs).
Instead of relying on pre-built transaction templates, RAW signing lets institutions construct and sign custom transactions directly, all while keeping private keys locked inside Fireblocks’ multi-party computation (MPC) architecture. Pair that with Iagon’s Cardano-specific node infrastructure, and you get a pipeline purpose-built for institutions that want to touch Cardano without building their own plumbing.
What the integration actually enables
The collaboration bundles native staking, on-chain governance participation, and CNT operations into a single institutional-grade workflow. Firms can now delegate ADA to stake pools, vote on Cardano governance proposals, and manage native tokens, all from within Fireblocks’ custody environment.
Fireblocks has actually supported ADA since August 2021. The earlier implementation was more of a basic custody-and-transfer setup. This integration represents a meaningful upgrade, layering in the staking and governance features that make Cardano’s ecosystem distinct.
Fireblocks Trust, the company’s qualified custody arm overseen by the New York Department of Financial Services (NYDFS), provides the regulatory backbone here. It combines self-custody with what the company describes as zero counterparty risk.
Iagon’s bet on institutional adoption
Iagon operates decentralized storage solutions powered by AI-driven resource sharing, but its enterprise node and API services are what landed this Fireblocks partnership.
In March 2026, Iagon secured a $1.5 million loan denominated in ADA, using 54 million IAG tokens as collateral to fund ecosystem infrastructure development.
Notably, Iagon’s CEO publicly disclosed abstaining from certain votes related to the integration, citing conflicts of interest. Community discussion around the integration has also raised concerns about whether deeper institutional integration could centralize elements of a blockchain that prides itself on decentralization.
What this means for investors
The immediate implication is improved ADA liquidity. When institutions can custody, stake, and govern through a platform they already use for other assets, the friction cost of adding Cardano exposure drops significantly.
The names being floated as potential beneficiaries of this pipeline — firms like Revolut, Grayscale, and BNY Mellon — are speculative at this point. But the infrastructure is now in place for firms of that caliber to engage with Cardano’s ecosystem without custom solutions.
Cardano’s delegated proof-of-stake model lets token holders earn rewards without locking up assets or running validator hardware. The ability to delegate to stake pools directly through Fireblocks, rather than through a separate workflow, removes a real operational headache for institutional players.
As Cardano moves deeper into its Voltaire era of decentralized governance, the ability for institutional holders to participate in on-chain votes could shape the network’s evolution.
Iagon’s $1.5 million ADA loan collateralized by IAG tokens introduces token-level risk. If IAG’s value drops significantly, that collateral position becomes more precarious.
