Background and Context

The Rise of Decentralized Finance

Decentralized Finance has evolved from a niche experiment into a full-fledged movement. By eliminating intermediaries like banks and financial institutions, DeFi empowers users with direct control over their assets, thanks to blockchain-based smart contracts. Ethereum, the pioneer smart contract platform, has paved the way, but high gas fees and network congestion have led to the need for improved solutions.

What is Arbitrum?

Developed by Offchain Labs, Arbitrum is one of the most prominent Layer 2 scaling solutions built for Ethereum. By using optimistic rollups, Arbitrum processes transactions off-chain and only resorts to the Ethereum mainnet to resolve disputes or finalize data. This method decreases transaction congestion and reduces gas fees drastically. For a more technical breakdown, visit How Does Arbitrum Work.
