I’m not talking about issuing claim (an expensive operation) for all addresses, I’m talking about taking a snapshot of user stAAVE balance at some point, nulling them and then airdropping registered amount to each address on ETH network or on Matic network. If done on ETH network, is a regular ERC20 transfer covering at least 100 to 110 adressess in one transaction.
And if done on Matic, it will cost less than 100$ even it needs to be sent to 10k addresses.
