Within the request's pinned block window (fromBlock 0x189378e to toBlock 0x18984a4, both inclusive) on Ethereum mainnet, sum the weightAdded argument of the `event Deposited(address indexed contributor, uint256 indexed hour, uint256 amount, uint256 creditedDelta, uint256 weightAdded, uint256 newWeight, uint256 txCount, uint256 hourTotal, uint256 earlyBps)` events emitted by the contract 0xcb0b0531e86a9ac36fa865ca8e3dbccf047fda91 grouped by the indexed contributor argument (topic 1 of the log), never by a data field. Return the 32 keys with the largest sums, descending by sum, ties by address ascending (lowercase hex).
