To make this easier, today I added a "Proof of Liabilities" button which only shows you information pertinent to proving that (1) an address on bitcoin has enough money to pay you your liabilities (2) you have a key in that address (3) you have enough signatures from the operator to let you withdraw your money unilaterally after a timelock

These items are sufficient to prove that the reserves exist and that the liabilities toward you exist...but they do not prove you will actually be paid, because a malicious operator could steal the money from the proof_of_reserves address with help from a prior holder of your statecoin
