summary
Shows concrete scripts using py-substrate-interface (Python) and the polkadot-js api (JavaScript). Python example reads a file of addresses, sends existential deposits then BILD transfers (Kusama Asset Hub asset IDs 2–3), composes a utility.batch of transfer_keep_alive calls, signs and submits extrinsics and checks hashes/events. JavaScript example scans bags to pick the top 22,500 nominators, issues permissionless put_in_front_of extrinsics to reorder accounts, estimates fees with paymentInfo, runs daily before elections, and reduces costs from ~11 DOT first run to ~1–3 DOT/day after optimizations.
