Educational only. Do not paste real funded keys. This page scans a numeric range of private scalars and tests derived addresses against the local bloom filter.
Sequential keys use fast pub + G point steps after the first full multiply.
SPIN picks a uniform random key in [start, start+width\u22121] (clamped below curve order). Max width 100,000,000. Auto mode steps sequentially and saves progress every 5000 keys.
