🚨 SharpLink Deploys $400M in ETH to Earn Yield
.@Sharplink has deployed $400M worth of ethereum:native across @ether_fi and @LidoFinance to improve returns on its ETH treasury
• $200M allocated to Lido for staking, receiving wstETH
• The remaining ETH deployed through Ether.fi to Linea, with EigenCloud restaking to pursue additional DeFi yields and incentives
Institutional ethereum:native adoption is moving beyond simply holding and staking. Companies are increasingly exploring restaking and DeFi to make their ETH treasuries more productive
The opportunity is bigger yield, but it also comes with additional smart contract and protocol risks

The institutions building the future of finance are building on @ethereum.

What does it mean to be a “frontier blockchain”?
It means that, through dozens of upgrades, we're upgrading past the name blockchain. No other innovates its own fundamental parts so regularly without even a second of downtime. While others chase adoption through compromises, Ethereum remains confident users follow the most robust chain.
Ethereum Institutional is making that case clear. Institutions will build on Ethereum not because it optimizes for the highest bidders, but because it is the only blockspace capable of meeting the highest standards. The cryptographic world computer will have no equal. Read more here about where we've been and where we're headed on EI's visualization of Vitalik's blog post.
1 / @ethereum is still called a blockchain. By 2030, that word won't cover it.
We turned @VitalikButerin's essay "The cryptographic world computer" into a visual reading: every block checked with one proof, final in seconds, built by many.

🏆 After more than two months of building, we’re excited to announce the winners of the EAG Global Buildathon (Online).
Some projects had previously joined our IRL hackathons and continued to build and improve, while others joined online and stood out with what they built.
Here are the 5 winning projects🧵:

Nethermind Client 2.0.0 is out. It changes how the node stores Ethereum's state: archive nodes drop from ~30 TB to ~2 TB, you choose the history you keep, and blocks process 2–3× faster than the previous release on a fresh node.
Nine years since the first commit. The fastest execution software we've ever built.
Breaking changes; read the notes before upgrading. Release: github.com/NethermindEth/net…
Más de 25 hackers para construir en menos de 48 horas más de 14 proyectos que usan tecnologías de @ethereum, inteligencia artificial, Smart devices y Open source software. 🦾
Esto fue posible por el apoyo de @HashKeyGroup, @EthAppsGuild, @icesi, @EFDevcon y @ekinoxis.
Es muy inspirador ver cómo jóvenes se animan a construir en estas tecnologías de frontera, donde menos del 2% del mundo entendiendo cómo funciona para
construir valor para las generaciones actuales y futuras.
Los ganadores están elegidos, esperen pronto ser anunciados. 👀
