I agree with your opinion that it might be criteria for their anticipated airdrop. I have been actively participating in its test net campaigns and completed all necessary task required to qualify for Scroll network airdrop. I am hopeful that announcement will probably made in first quarter of 2024.
but anyway maybe a multiplier to the airdrop possible.
This seems possible since they had 3 phases, who deployed contract early got different nft, so it could be used as criteria with early deployers getting highest multiplier. Out of 1.1M, significantly less would have deployed early.
Also, unique contract deployers may get better allocation, almost every one of these 1.1M would have used those online contract deployers, which ofc helped in completing task but may not help in qualifying for much Scroll tokens. Let's see how this goes.
