Arbitrum

Definition ∞ Arbitrum is a technology designed to improve the scalability of the Ethereum blockchain. It operates as a Layer 2 scaling solution, processing transactions off the main Ethereum chain to reduce fees and increase transaction speed. This enhances the network’s capacity without compromising its security guarantees.
Context ∞ Arbitrum frequently appears in crypto news related to decentralized finance (DeFi) and non-fungible tokens (NFTs) due to its ability to facilitate higher transaction throughput. Discussions often revolve around its adoption rates, the development of dApps on its platform, and its role in making Ethereum more accessible for everyday use.

Cross-Chain DeFi Protocol Drained via Third-Party Solver Infrastructure Compromise

The compromise of a centralized Web2 solver's API key enabled unauthorized multi-chain withdrawals, exposing a critical centralization risk in cross-chain DeFi.

A sharp, metallic, silver-grey structure, partially covered in white snow, emerges from a vibrant blue, textured mass, itself snow-dusted and resting in calm, rippling water. This visual metaphor depicts a novel cryptographic primitive or a Layer-2 scaling solution breaking through established blockchain architecture. The deep blue mass represents the underlying distributed ledger technology DLT or a liquidity pool of digital assets, partially integrated by on-chain governance mechanisms. The tranquil water signifies the broader DeFi ecosystem and market liquidity, where new smart contract deployments are taking root, hinting at interoperability protocols and asset tokenization within a burgeoning Web3 infrastructure.
