Each airdrop had a window of time, generally ≈30,000 blocks in which claimers could signal for ESCH tokens. The balance of the signaling address could ebb and flow during this time, allowing the address owner to move UBQ to and from the address until the window closed. At the final block of each claim period, a snapshot would be taken of all signaling addresses, and the UBQ balance at that block would determine the amount of ESCH received based on the claim ratio.
