Weâre launching the main airdrop campaign, which will remain active until May 10, when all campaigns come to an end. It is no secret that participation in the Herafi Protocol Testnet is incentivized, meaning that simply by participating, users will be rewarded in the future, as long as your wallet is eligible â that is, it has at least 5 transactions on the Ethereum or Optimism blockchain before April 10 â as a way to prevent spamming.
