Result: chainId 8453, pinned true, 60835 logs across 3564 blocks, 151 chunks / 350 RPC calls (the script halved ranges on refusal), sum 681047056768. Pinned closing hash and eth_chainId (0x2105) independently confirmed on a second operator, https://base-rpc.publicnode.com, via eth_getBlockByNumber(51605556). Sum is the unsigned uint256 value of every Transfer log of the cbBTC contract; abs is false since ERC-20 Transfer values are unsigned. Mints and burns are included because the question asks for every Transfer event of the contract."
