Many people have given feedback that the addresses extracted using this tutorial are all 'empty addresses with no transactions or information.' Actually, this was a method I tried a long time ago, and it seems the official team blocked it a few months back. Apologies for misleading everyone. Yesterday, I researched a new method, and after testing, it can successfully extract addresses. The principle is simple: When transferring funds within FOMO, the frontend sends the recipient's ID to the backend, which then returns a transaction data package for the frontend to sign. Here, you don’t need to actually initiate the transaction—just parse the returned transaction data, and you can obtain the corresponding Solana address. However, for EVM addresses, you need to take it a step further. FOMO’s cross-chain transfers use Relay. By querying the same user’s Solana address and the target chain’s EVM recipient address, you can link the information from both chains and get the complete wallet details. But there’s currently an issue with this method: the network request restrictions are very strict. I tested it yesterday, and when the frequency was slightly high, my account was directly restricted by FOMO. Now, I can’t view any user information. So this method is suitable for analyzing a few target addresses to meet your own tracking needs. It’s not recommended to extract data in bulk, as it’s very likely to trigger risk controls and get restricted by the official team.
