At Chorus One, we aim to provide users with a best-in-class experience across a wide variety of networks. To maintain this standard, we periodically assess our supported networks for current and future viability. After a comprehensive review where we also consulted with clients, Chorus One has made the strategic decision to offboard 7 protocols from our staking services portfolio. These include:
This move reflects our commitment to operational excellence and client value maximization and does not reflect on the capability, performance, or potential of these protocols. Each has merit and continues to serve the broader ecosystem effectively.
We are proud to have supported these networks and their users. However, there are a few trends we have observed that have led to our decision:
Market Conditions: The volatility and price movement of the affected networks’ tokens have impacted their sustainability from a node operation perspective. In uncertain market conditions, it’s crucial for us to prioritize networks that show resilience and consistent growth.
Low Network Activity: Despite their early potential, the applications and user adoption on these networks have not reached the levels necessary to justify continued support. In our commitment to delivering the best experience to our users, we believe it’s important to focus on networks with higher engagement.
If you’re currently staking tokens on any of these networks, we kindly ask that you migrate them to a different validator by July 31, 2025. After this date, staking rewards from our public nodes will no longer be guaranteed. Please ensure your tokens are unstaked or re-delegated before then.

This decision allows us to allocate more resources and attention to the networks that show the most promise in terms of activity, user growth, and long-term sustainability. As we continue to grow and evolve, we remain committed to offering the best staking services and supporting the most innovative and active networks in the industry.
If you have any questions or need assistance with unstaking your tokens, our support team is here to help. Feel free to reach out to us via support@chorus.one.

Earlier this year, Chorus One (“Chorus”) introduced TON Pool – TON staking, built for institutions. TON Pool redefines staking on TON by combining security-first architecture, performance optimization, and seamless developer-ready integrations to eliminate the friction that once defined, and hindered, staking on TON.
Today, Chorus is pleased to announce the launch of the TON Pool dApp, making TON staking even simpler, more accessible to all.
Chorus’ TON Pool is the most secure pooled staking solution in the TON ecosystem with smart contracts fully audited by Spearbit, and ongoing optimizations aimed at maximizing annualized staking returns (ARR).
This makes TON staking more accessible by removing its high barriers to entry–
In addition, Chorus One has consistently outperformed in staking rewards for TON Pool since its launch. We do this by optimizing our bidding process for election cycle participation.
When TON Pool was first launched, it was accessible only via SDK and API. Now, anyone can easily access TON Pool through Chorus’ new dApp, no technical skills needed!
Start staking TON with just a few simple steps.

As announced earlier this year, Chorus One is proud to have launched TON Pool, an institutional-grade pooled staking solution on Telegram Open Network (TON) that enhances the staking experience with a focus on security and addressing technical risks.
TON Pool has been based on the work of the Ton Whales team. As part of our commitment to offering institutional-grade solutions, Chorus One partnered with Spearbit to complete a smart contract audit that revealed the underlying Ton Whales contracts lack adequate risk mitigation, potentially leading to users' staked tokens being lost.
Our audit identified two critical risks:
Both of these issues have been mitigated in the Chorus One’s TON Pool. These issues have not been mitigated in the original Ton Whales contract, and users staking to Ton Whales should be aware that if either of these above risks occurs, their stake may be lost.
Efforts to help secure Ton Whale stakers
Chorus One has proactively engaged the Ton Whales team in an effort to protect the community, and as a good community member, to respect the Ton Whales smart contracts. Chorus One initially sent the smart contract findings in early March and again reached out to them before making our updated smart contracts publicly available and publishing this article. Up till the time of writing, we have not heard back from the team behind those contracts, which brings concerns as ignoring these risks puts the stake and the ecosystem at a vulnerable position. As of now, Ton Whales has not addressed the issues found, at least not in the open-sourced contracts.
Assuring the continued security of the Chorus One Ton Pool
Chorus One continues to test and, where necessary, improve the security of the Chorus One TON Pool. This is done by actively testing proprietary solutions internally and with our partners.
A Commitment to the Community
At Chorus One, we aim to deliver innovative products and advocate for a safer digital assets environment. We are committed to leading in security and challenging the status quo.
In conclusion, our TON Pool staking solution sets a higher standard for security and trust. We encourage users to evaluate their options carefully and build a safer future for digital assets together.

Coindesk and others reported on today's launch of the REX-Osprey SOL + Staking ETF, highlighting its pioneering approach as the first U.S. exchange-traded fund to combine crypto exposure with on-chain staking rewards. Trading on the CBOE and structured under the Investment Company Act of 1940 (‘40 Act), the fund offers investors access to Solana (SOL) while earning yield from staking. This is a watershed moment in digital asset finance because staking yield is no longer limited to wallets and validators.
To sidestep the long regulatory bottlenecks of the ‘33 Act spot ETF route, Osprey and REX opted for the more nimble ‘40 Act structure. They created a C-corporation that owns a Cayman-based subsidiary, which in turn acquires and stakes SOL tokens. This clever structuring enabled the ETF to launch faster and earn SEC clearance with a “no further comment” letter.
The result? Institutional-grade exposure to SOL, with staking yield, wrapped inside a regulated, listed fund. It’s a huge step forward in making staking mainstream and accessible via trusted financial rails.
While fast, this C-corp route has its drawbacks. As The Block outlines, C-corporations are subject to corporate tax, meaning some of the staking rewards could be liable for taxation before being realised by shareholders. And while the SEC had no further comment about the fund’s launch, this sparks an intriguing dialogue about the opportunities for innovation in fund compliance with ‘40 Act requirements, especially around asset composition and disclosure.
Ultimately, it's a practical solution that allows for the introduction of staking to the market right now, with exciting opportunities for future enhancements.
Encouragingly, the Osprey ETF may only be the beginning. Bloomberg’s James Seyffart recently noted that grantor trusts, the structure used in today’s spot Bitcoin and Ethereum ETFs, may soon be permitted to include staking. If approved by the IRS, this would allow ETF sponsors to pass staking income directly to shareholders without triggering corporate tax obligations.
This would remove the biggest efficiency drag from staking ETFs and enable more streamlined product designs with broader market appeal.
This shift toward efficiency is being propelled by a wave of pending legislation. Chief among them is the CLARITY Act, introduced in May 2025, which aims to:
Alongside this, other crypto-relevant bills are gaining momentum:
Of course, not all of these bills will become law, but it is clear that the legislative and regulatory environment is increasingly pro-clarity, pro-infrastructure, and pro-innovation. Osprey is the vanguard, but the next generation of staking ETFs will likely be faster, simpler, and more tax-efficient.
Bottom Line: The Osprey SOL + Staking ETF is an exciting breakthrough. It unlocks staking yield for ETF investors using creative structuring and regulatory navigation. Even better, a suite of legislative and tax changes is lining up to make these kinds of products simpler, leaner, and more mainstream. This is how crypto goes institutional.
