self-custodial wallet Apple App Store
When you try to download a crypto wallet on your iPhone, you might notice something odd: many popular decentralized exchanges (DEXs) and self-custodial wallets are missing from Apple's App Store. This isn't an accident — Apple actively rejects self-custodial wallet and DEX apps based on strict policies
bitcoin inheritance
What if your Bitcoin could automatically transfer to your heirs without involving a single lawyer, judge, or custodian? While traditional estate planning requires legal intermediaries and months of probate proceedings, Bitcoin's OP_CSV (CheckSequenceVerify) time-lock mechanism enables completely trustless inheritance through cryptographic smart contracts that execute automatically after
Cardano Bitcoin DeFi

Layer 2 security risks
The Wormhole Bridge hack of 2022 wiped out $325 million in a matter of hours. The Ronin Bridge exploit drained over $600 million. These weren't smart contract bugs or cryptographic failures — they were multisig wallet compromises caused by human operational failures, not mathematical flaws. Despite Layer 2 protocols
Ethereum layer 2 security
When JPMorgan launched their $5 billion MONY tokenized money market fund in February 2026, they made a telling decision: deploy directly on Ethereum mainnet, not Layer 2. Their reasoning? "Security settlement layer considerations." This wasn't just corporate conservatism—it was recognition of a fundamental vulnerability plaguing
layerzero
On April 18, 2026, the crypto world witnessed one of its most sophisticated infrastructure attacks when North Korea's Lazarus Group drained 116,500 rsETH ($293 million) from Kelp DAO's liquid restaking protocol. What makes this layerzero security vulnerability particularly alarming isn't just the massive
layerzero
On April 18, 2026, the crypto world witnessed one of the most sophisticated cross-chain bridge attacks in DeFi history. The LayerZero bridge vulnerability — a failure in single-verifier configuration combined with RPC infrastructure compromise — enabled hackers to drain 116,500 rsETH ($290 million) from Kelp DAO without exploiting smart contract code.
cross-DEX tracking
The $5.4 billion daily DEX trading volume across 1,100+ platforms creates a fragmented liquidity landscape that traditional analytics tools struggle to track. While individual DEX data is readily available, monitoring cross-platform activity, MEV extraction, and liquidity migration patterns requires sophisticated on-chain analysis techniques that most traders and developers
cross-DEX tracking
The $412 billion monthly DEX volume across multiple chains in 2025 created a new challenge: cross-DEX tracking requires monitoring 450+ protocols across 45+ blockchains to correlate trading activity, liquidity flows, and user behavior when assets move seamlessly between Uniswap, PancakeSwap, SushiSwap, and dozens of other protocols. Traditional single-chain analytics fall
domain hijacking crypto
Key Takeaways:CoW Swap lost $1.2 million in 90 minutes on April 14, 2026, when attackers hijacked swap.cow.fi through forged documents submitted to Finnish domain registry Traficom, according to KuCoin News.Domain hijacking in crypto exploits DNS infrastructure weaknesses to bypass blockchain security—smart contracts remained secure
defi yield farming
Imagine your money working for you 24/7, earning returns while you sleep. That's the promise of DeFi yield farming — a revolutionary way to generate passive income by lending your cryptocurrency to decentralized protocols. DeFi yield farming allows users to earn 3-50% APY by providing liquidity to decentralized
