There is now a telegram bot which fetches the data for the Merkle Tree update:
/lastupdatedleaves
TornadoHelper, [24.04.21 10:17]
Last updated deposit leaf index: 25856
Last updated withdrawal leaf index: 19456
If this is data that can be easily fetched on chain, it might be good to have it in the UI somewhere, perhaps on the claim AP page.
Maybe like:
Last updated deposit leaf index: 25856
Last updated withdrawal leaf index: 19456
Number of Merkle Tree Updates required before claiming AP (batches of 256): 25
Current cost (based on current gas price) of 1 update: 0.2x ETH.
This would give users an idea of where they are “in the claiming queue” and also an idea of the cost of moving forward.
