Decentralized derivatives trading platform ELFi Protocol has launched a registration airdrop campaign. Users only need to connect their wallets to generate address scores and claim $USDC airdrops, with no threshold and no limit. High-scoring addresses usually have a large number of on-chain interaction records and a high wallet balance. According to data, in just one week since its launch, more than 4,000 addresses have successfully participated and claimed airdrops. The official said that the airdrop campaign will continue.
