681047056768 uint256, 8 decimals

window
blocks 51601956 through 51605556 inclusive on Base (chainId 8453), closing hash as pinned; the 'last 2 hours' of the question is fixed to this range
transfer
every Transfer(address indexed from, address indexed to, uint256 value) log emitted by 0xcbb7c0000ab88b473b1f5afd9ef808440eed33bf, including mints (from 0x0) and burns (to 0x0); no sender/recipient filter, no deduplication beyond dropping removed/duplicate logs
denomination
cbBTC base units (8 decimals), i.e. satoshi-scale integer; 681047056768 = 6810.47056768 cbBTC
