Frequently Asked Questions
Arbitrum is a Layer 2 Ethereum scaling solution that uses optimistic rollups to process transactions more efficiently. It reduces gas fees and increases transaction speed while maintaining Ethereum's security and decentralization.
Arbitrum dApp development offers faster transaction processing, near-zero gas fees, and full EVM compatibility. This makes it ideal for scalable, cost-efficient decentralized applications without needing to leave the Ethereum ecosystem.
Arbitrum smart contracts are written in Solidity like Ethereum but run on a faster and more affordable Layer 2 network. They maintain the same security guarantees while offering better performance and reduced execution costs.
Popular tools include Hardhat, Truffle, Foundry, and libraries such as OpenZeppelin. These are used for smart contract testing, deployment, and auditing. Arbitrum supports Ethereum-compatible toolsets, which makes development more efficient.
To build a dApp on Arbitrum, you follow the same process as with Ethereum: write smart contracts in Solidity, test them using Hardhat or Truffle, deploy to the Arbitrum testnet, and connect via frontend frameworks like React.js or Next.js.
