Ethereum is moving ahead with EIP-8141 while Coinbase-backed Base backs EIP-8130, leaving wallets and apps that span both networks facing different transaction systems.
Security firms traced the $7.8 million loss to a helper contract the wallet owner had authorized, not to Safe itself.
OneKey demonstrated how an outdated Ethereum app could sign a transaction different from the one shown on a Ledger device, but the wallet maker says the vulnerability had already been fixed.
Coinkite's latest firmware requires users to add their own randomness when generating wallet seeds and fixes additional security issues uncovered during a three-week review.
The StopAndProtect operation used compromised WordPress websites to spread malware, steal crypto wallet files, and deploy ransomware.

Overview
A crypto wallet is a software or hardware tool that stores the cryptographic keys needed to send, receive, and manage digital assets. It does not hold coins or tokens directly; instead, it holds the private keys that prove ownership and authorize transactions on a blockchain. Wallets are the primary entry point for most users into the Web3 ecosystem.
How It Works
A wallet generates a pair of cryptographic keys: a public key, which becomes the wallet address others use to send funds, and a private key, which signs transactions to prove you own the address. Software wallets (hot wallets) run on phones, browsers, or desktops for convenience, while hardware wallets (cold wallets) keep keys on a dedicated offline device for stronger security. Most wallets also derive keys from a seed phrase so a user can restore access on any compatible device.
Why It Matters
Because private keys are the only thing standing between a user and their funds, wallet security determines the safety of every interaction in Web3. Losing a private key means losing the assets it controls forever, with no recovery mechanism. Choosing the right wallet type and handling keys carefully is therefore the most fundamental security decision a crypto user makes.

Wallets connect to the broader security and identity landscape: the Private Key and Seed Phrase they store, smart contract wallets enabled by Account Abstraction, and services like ENS that turn addresses into readable names.
