Wololo - Ethereum Wallet Simulator

Noordzee Ventures

An extension that emulates Ethereum wallet functionality, enabling users and developers to test app interactions without a real wallet. It offers an easy way to simulate wallet connections with either a randomly generated Ethereum address, ENS names like vitalik.eth, or a custom address you specify—ideal for testing features or checking airdrop eligibility safely. Network supported: Ethereum Mainnet and Testnets, Arbitrum, Base and Optimism.
