Hi there!
We’re only a few days into April, and the drama is already peaking. From hackers losing stolen ETH to phishing scams (karma, maybe?) to founders bargaining with exploiters just to keep their DeFi dreams alive—it’s been a wild ride. Meanwhile, adoption is growing, regulators are stirring, and big names like BlackRock and Trump are making crypto moves.
As usual, here is a roundup of the stories that shook the blockchain world this past week.
Enjoy!
DeFi protocols zkLend and SIR.trading have recently suffered major setbacks following targeted exploits that highlight the sector’s persistent vulnerability to attacks.
zkLend lost $9.6 million in a flash loan attack. In an unusual twist, the hacker later admitted—via an on-chain message—to accidentally sending most of the stolen ETH to a phishing site mimicking Tornado Cash. The attacker expressed regret and urged zkLend to pursue the scammers instead. Despite offering a 10% white-hat bounty and a $500,000 reward for information leading to an arrest, most of the stolen funds remain unrecovered.
SIR.trading, a protocol designed for safer leveraged trading, was exploited for $355,000 due to a vulnerability introduced by Ethereum’s recent Dencun upgrade. The founder, Xatarrer, appealed directly to the attacker, offering $100,000 as a “fair share” if the remaining funds were returned. Built with community support and no VC funding, the platform’s survival now hangs in the balance.
These incidents come amid a broader uptick in DeFi exploits. According to CertiK, nearly $29 million was lost to attacks in March alone—underscoring the urgent need for stronger security practices across the space.
According to data from CoinGecko, these are the five biggest gainers of the week:

Shardeum Gears Up for Mainnet Launch, Promises Scalable and Accessible Blockchain
Shardeum, the world’s first Ethereum Virtual Machine (EVM)-based autoscaling Layer 1 blockchain, will launch its mainnet on April 15, 2025. Powered by Dynamic State Sharding, the network can scale transaction throughput automatically as more validators join. With over 171,000 validators and 81M+ testnet transactions, Shardeum aims to solve blockchain’s scalability trilemma without sacrificing decentralization or security.
Why It Matters
Shardeum’s approach could redefine blockchain infrastructure by making scalability native and validator participation accessible. Its lightweight hardware requirements and decentralized design may help onboard emerging markets and support global Web3 growth.
