TL; DR
- Fire blocks says it has launched ETH Staking Link, a standardized interface for institutional Ethereum integrations.
- The company says that more than 36 million ETH, roughly 30% of the circulating supply, is now invested in Ethereum.
- Fireblocks says Ethereum staking on its platform has more than doubled in the past six months.
- The update also highlights post-Pectra compounding validators, which can support balances up to 2,048 ETH instead of the original limit of 32 ETH.
Fireblocks says institutional Ethereum staking is moving into a more standardized phase as the amount of ETH committed to validators continues to grow across the network.
In a June 11 post, the cryptocurrency custody and infrastructure company unveiled the ETH Staking Link, a standardized interface intended to make it easier for stakeholders to connect their validator infrastructure to Fireblocks’ institutional platform. The company framed the launch as part of a broader effort to make stake operations more consistent for asset managers, custodians, exchanges and other professional crypto firms.
Ethereum Staking is becoming an institutional infrastructure
The numbers behind the shift are significant. Fireblocks said more than 36 million ETH have now been invested, representing roughly 30% of Ethereum’s circulating supply, with around a million active validators securing the network.
That scale has changed the way institutions approach the role. For smaller users, staking may seem like a simple yield mechanism. For large platforms and custodians, it becomes an operating system that includes validator selection, slicing controls, key management, liquidity planning, reporting and client-level permissions.
Fireblocks said the volume of stakes on its own platform has more than doubled in the past six months. While this is a platform-specific figure, it fits a broader trend of stakes becoming part of institutional exposure to Ethereum rather than a niche technical feature.
New providers added to Fireblocks Staking link
The company said ETH Staking Link is expanding support to Blockdaemon, P2P.org and MAVAN, while existing providers Figment and Kiln remain available. Fireblocks described the interface as a way to reduce friction for providers and institutions that need consistent integration standards across the stake infrastructure.
The announcement described Blockdaemon securing more than $110 billion in blockchain infrastructure, while P2P.org was described as backing more than $10 billion. MAVAN is presented as the largest single staking operation globally.
The main point for Ethereum is not only the number of service providers. Staking is becoming a modular infrastructure, with custody, validator operations, and institutional controls increasingly performed via standardized rails.
Pectra replaces Validator Math
Fireblocks also pointed to a post-Pectra validator environment. Ethereum’s Pectra upgrade, activated on the mainnet in May 2025, introduced support for complex validators, sometimes called 0x02 validators.
According to the original stake model, validator balances are built around a structure of 32 ETH. The newer design of the combined validator can support balances of up to 2,048 ETH, making it easier for larger operators to manage stake positions without splitting capital across as many separate validator units as possible.
For institutions, this can simplify work and reduce fragmentation. It may also make staking more attractive to larger ETH holders who want yield exposure but need cleaner infrastructure and reporting.
Why this is important
Ethereum staking is now a key part of the network’s economy. As more and more ETH is dedicated to validators, the investment infrastructure becomes increasingly important for both security and institutional access to the market.
Fireblocks’ update does not itself change the Ethereum protocol. But it shows how service providers are building an operational layer around the network. For institutions, the next stage of stake may be less about whether they can invest ETH at all and more about whether they can do so with the controls, integrations and risk standards expected in professional finance.
