Here are some major developments across the crypto and DeFi space this week:
1) SBI Holdings’ institutional market maker subsidiary, B2C2, has chosen Solana as its primary network for processing and settling stablecoin transactions.
B2C2, which provides liquidity to major firms and has partnerships with companies like Standard Chartered and Anchorage Digital, will route large-scale flows through Solana, for institutional stablecoin activity.
----------
2) Keyrock has announced a new Series C funding round at a $1.1B valuation, underscoring continued investor support for established digital asset infrastructure firms despite a weak broader venture backdrop.
The round is being led by SC Ventures, the investment arm of Standard Chartered, with additional participation from Ripple, an existing backer
While the company did not disclose the amount raised so far, management indicated the round remains open and could ultimately reach $100M.
----------
3) Anchorage Digital and Chainlink Labs have backed the launch of the Blockchain Leadership Fund, a new crypto-focused political action committee aimed at supporting candidates advancing digital asset and blockchain policy ahead of the US midterm elections.
For Anchorage, the move marks its first direct involvement in funding a PAC, while for the industry more broadly it underscores a continued effort to shape the regulatory environment through more coordinated political advocacy.

4) International payments network Swift has completed the design of its blockchain-based shared ledger and is now building the first version to enable continuous cross-border payments using tokenised bank deposits, with live transactions expected to begin this year. It is working with banks globally to expand functionality and support the transition to digital finance.
Swift will operate and coordinate the ledger, while banks retain control over their assets and settlement processes. The initiative sits alongside broader efforts to improve payment speed, transparency, and reliability for consumers and businesses.
The system builds on existing Swift infrastructure, adding a shared layer that records and validates payment commitments while supporting compliance processes and multiple settlement methods. Developed using open-source, EVM-compatible technology, it is designed to integrate with the broader digital asset ecosystem and scale over time.

5) The Google Quantum AI team at Google Research has published a new whitepaper warning that future quantum computers could break the elliptic curve cryptography used by most cryptocurrencies, including Bitcoin, which is used in digital signatures to secure transactions and wallets.
The research estimates this could be achieved using under 1,200–1,450 logical qubits and ~70–90M Toffoli gates, implying roughly a 20× reduction in the number of physical qubits required compared to prior estimates.
The paper calls on the crypto industry to begin transitioning to post-quantum cryptography, new cryptographic schemes designed to remain secure against quantum attacks, to ensure long-term security and stability. While still beyond current hardware capabilities, Google emphasizes the threat is becoming more feasible.

6) Lido DAO is considering a one-off $20M LDO buyback as the token trades close to record lows, framing the move as an opportunistic use of treasury capital rather than a routine intervention.
The proposal, published on Friday, would allow the DAO to deploy up to 10,000 stETH to repurchase LDO, potentially absorbing a meaningful share of the circulating supply at current prices.
----------
7) Nakamoto disclosed that it sold 284 BTC for approximately $20M in March, at a price materially below its average holding cost.
Based on the company’s filing, the sale was executed at roughly $70,400 per BTC, representing around a 40% discount to its reported average purchase price.
----------
8) BNP Paribas is expanding its exchange offering by introducing 6 crypto-asset exchange traded notes (ETNs) indexed to Bitcoin or Ether, to its French retail investment offering, enabling clients to gain exposure without directly holding the assets.
These ETNs are available from March 30, 2026, for retail, entrepreneurial, private banking, and Hello bank! clients in France, with plans to extend access to wealth management clients internationally.
----------
9) In its latest 10-K, filed this week, GameStop disclosed that it did not sell the 4,709 BTC position worth roughly $324M as of 31 January.
Instead, the company pledged the bitcoin as collateral with Coinbase Credit and used part of the position in a covered-call strategy with strikes set at $105,000-$110,000.
----------
10) U.S. authorities have charged 10 foreign nationals linked to firms including Gotbit, Vortex, Antier, and Contrarian for allegedly running coordinated crypto “pump-and-dump” schemes. Prosecutors say the group artificially boosted token prices and trading volumes through structured trading, then sold at inflated levels, leaving investors with losses.
The FBI uncovered the scheme through “Operation Token Mirrors” by creating its own token, NexFundAI, and presenting it as a legitimate project to engage market-making firms.
----------
11) Digital asset treasury company, Bitmine Immersion Technologies (BMNR) has launched MAVAN (Made In America Validator Network), its proprietary staking platform initially built to support its Ethereum treasury.
As of March 24, 2026, the company has staked 3,142,643 ETH (worth $6.8B at $2,148 per ETH via Coinbase), with expected annual staking rewards of $300M once fully deployed at a 2.83% 7-day yield.

EDGE is the native token of the decentralized derivatives protocol, edgeX.
Total supply is set at 1 billion EDGE. Of this, 30% is allocated to early users, split between:
alongside:
The EDGE token is used for:
Governance: allowing holders to vote on protocol decisions such as market listings and fee structures.
Staking: to earn a share of trading fees generated on the platform.
Trading fee discounts
Incentivizing traders, liquidity providers, and other ecosystem participants.
In the future, it may also have a role in supporting the network’s infrastructure and security.
The release schedule differs by category:
genesis tokens are fully unlocked at genesis
Pre-TGE rewards unlock 24 hours later
ecosystem and community tokens and foundation tokens are locked for 12 months after TGE before 24 months of linear monthly vesting
future reserve tokens are locked for 18 months before 24 months of linear monthly vesting
core contributor tokens are locked for 24 months before vesting begins.
Another important feature of the token is the 30% future reserve.
For token holders, that reserve is therefore both a source of strategic optionality and a potential source of dilution risk.
