Arbitrum (ARB): A Leading Ethereum L2 para DeFi Brasileiro

Arbitrum é a largest Ethereum Layer 2 por TVL e activity — making Ethereum DeFi affordable para everyone. Com Optimistic Rollup technology, Arbitrum offers 10-100x cheaper transactions que Ethereum mainnet while maintaining security. Para brasileiros, Arbitrum é o best L2 para accessible DeFi.

O Que É Arbitrum?

Launched em 2021 por Offchain Labs (Ed Felten, Steven Goldfeder, Harry Kalodner):

  • Optimistic Rollup — Assumes transactions are valid, challenges if not
  • EVM-compatible — Runs Ethereum smart contracts directly
  • ~10x cheaper — Gas fees 10-100x lower que mainnet
  • Growing ecosystem — Largest L2 TVL (~R$ 15B+)
  • ARB token — Governance token (launched March 2023)
