• SharpLink buys 10k ETH from EF.

• BTCT announces a $1m ETH reserve.

• Ethereum Time Capsule opens submissions.

• Dynamic single-click smart wallets on ZKsync.

SharpLink Gaming has acquired an additional 10,000 ETH at an average price of $2,572.37 per ETH. With this purchase, SharpLink has become the largest publicly traded company to maintain a strategic ETH treasury reserve and now ranks as the second-largest ETH-holding entity after the Ethereum Foundation. The transaction was conducted over the counter directly with the Ethereum Foundation. Proceeds from the sale will fund the Foundation’s core operations, including protocol research and development. SharpLink Gaming now holds a total of 215,957 ETH in its treasury.

BTC Digital Ltd. announced the creation of a $1 million strategic Ethereum reserve, making it the latest company to shift from Bitcoin mining to Ethereum. The company aims to engage in DeFi, stablecoin issuance, and asset tokenization as part of its broader strategy. The $1 million ETH purchase represents just an initial step, with plans to increase holdings over time. CEO Siguang Peng highlighted Ethereum’s role as the leader for stablecoin transactions, high-volume onchain payments, and innovative financial applications. ETH Strategy, an autonomous treasury protocol, also acquired 6,900 ETH for its ETH treasury.

In celebration of Ethereum’s 10th anniversary, the Ethereum Time Capsule is accepting encrypted digital messages from the community. Anyone can contribute stories, memories, or messages until submissions close on 30 July 2025. All entries will stay encrypted and will be publicly revealed one year later on 30 July 2026. Each submission costs 0.001 ETH on Ethereum Mainnet, with all proceeds going to the Protocol Guild. The capsule uses Shutter Network’s encryption to secure messages until the unlock date.

Wallet Provider Dynamic launched one-click smart wallets on ZKsync, featuring Single Sign-On (SSO). The integration enables the creation of embedded wallets secured by onchain passkeys using email or social login. As part of Dynamic’s Global Wallet solution, the embedded wallets are portable across any chain in the Elastic network.

• Path to a zkEVM on Ethereum L1.

ETH is up 11% in the last 24 hours, currently trading above $2,900 at the time of writing.

The U.S. Treasury and IRS removed a crypto broker rule, issued during the Biden Administration, which would have required certain decentralized finance protocols to report digital asset sales similarly to centralized exchanges. Since Congress and the President disapproved the rule under the Congressional Review Act (CRA), it has no legal force or effect and is treated as though it never took effect. As a result, the Treasury and IRS are reverting the regulations to their prior form. DeFi protocols that facilitate digital asset sales are no longer required to collect and report information to the IRS about their users.

HSBC, a major global bank, conducted an experiment under the Hong Kong Monetary Authority’s Project e-HKD+ to explore technical and commercial possibilities for a digital Hong Kong dollar. The experiment tested how digital money could operate on public networks such as Ethereum, Arbitrum, Linea, and Polygon, as well as a private blockchain developed on Hyperledger Besu. The tests focused on storing, transferring, and settling tokenized assets, exploring scalability, and examining privacy and security solutions using Privacy Enhancing Technology (PET) and Decentralized Identity. HSBC recently launched Hong Kong’s first bank-led tokenized deposit service for its corporate clients.

Rollup-as-a-service infrastructure provider Caldera introduced $ERA, its native token for gas fees, staking, security, and governance. $ERA has a total supply of 1 billion tokens, with 7% of the supply allocated for an initial airdrop. Eligible users must pre-register before July 16, 2025, to receive their allocation. $ERA will serve as the gas token for the Metalayer, Caldera’s interoperability protocol that unifies chains, enabling shared liquidity and secure, intent-based cross-chain bridging. Caldera supports custom rollup deployments on Arbitrum Orbit, OP Stack, and ZKsync through its modular Rollup Engine. Chains deployed via Caldera collectively secure over $400 million in TVL.

Ethereum researcher Sophia Gold published a post on paths to deploying a zkEVM on Ethereum L1. The post outlines proposed standards from the Ethereum Foundation’s zkEVM team, which defines real-time proving as achieving proof generation within 10 seconds for 99% of mainnet blocks. She believes several zkVM projects could achieve real-time proving before Devconnect ARG in November 2025. The proposed standards aim to make it feasible to run zk provers at home. L1 zkEVM would allow Ethereum to significantly raise the gas limit and support native zk-rollups, without sacrificing censorship resistance.

• Solidity celebrates 10 years.

• GMX suffers an exploit.

• Tokenized RWA TVL hits $25b.

• SEC statement on tokenized securities.

Solidity, the most widely used language for developing smart contracts on the EVM, is celebrating 10 years since the release of its high-level programming language and compiler in 2015. Solidity enables developers to write contract logic that compiles into EVM bytecode. Marking the milestone, Solx, a new alternative Solidity compiler, launched its LLVM-based compiler to beta. Solx automatically spills variables into memory. Looking ahead, the Solidity team aims to simplify the core language and shift more complexity into standard libraries, paving the way for a leaner and formally defined language.

GMX, the second-largest protocol on Arbitrum by TVL, suffered a $40 million exploit on its V1 instance. An attacker manipulated leverage-enabled functionality by opening a large short position just before redeeming the protocol’s LP tokens. It artificially inflated the vault’s Assets Under Management (AUM), allowing the attacker to redeem more funds than the GLP was worth. The root cause was that the executeDecreaseOrder function accepted a smart contract as its first parameter, instead of restricting it to an externally owned account, enabling the attacker to execute arbitrary code and manipulate the vault’s internal state. GMX V1 forks are urged to disable leverage and restrict GLP minting.

The market capitalization of tokenized real-world assets (RWAs) has surpassed $25 billion. Over 58% of tokenized RWAs reside on the Ethereum mainnet. ZKsync is the second-largest network by RWA TVL with more than $2.2 billion in tokenized assets. BlackRock’s BUIDL fund is the largest tokenized RWA with $2.8 billion in TVL.  According to data from rwa.xyz, the ecosystem includes 288,596 asset holders and 249 issuers. Meanwhile, stablecoin demand continues to surge, with the supply of stablecoins on Ethereum reaching an all-time high, reaching $131 billion in stablecoin market cap.

SEC Commissioner Hester M. Peirce issued a statement on the tokenization of securities, noting that while tokenized securities can enhance capital formation and asset use as collateral, they are still subject to federal securities laws. Peirce emphasized that tokenized instruments must meet the same legal requirements as traditional securities, and tokens could be classified either as distinct securities or as security-based swaps. Her statement follows Robinhood’s launch of Token Stocks, which are not yet available to U.S. users.
