Hand Switcher

Move supply from seller wallets to buyer wallets in bundled sell-and-buy pairs. Solana only.

Hand Switcher rotates supply between two sets of your wallets: sellers sell, the task's buyers buy, and each pair lands in one bundle. Buyers spend their own SOL. Solana only.

Wallets#

Each side is picked one of three ways: Custom wallets (pick by hand), Role wallets (every wallet with a role), or Role + custom.

  • Sellers — source of supply. With a role, the set is re-read every cycle, so wallets given the role later join in.
  • Buyers — the task's own wallets; they need coin. Min buyer SOL (Advanced) skips poor buyers.
  • A wallet on both sides only sells. An empty side stops the task before its first cycle.

Sizing and pacing#

  • Spend limit per buy — largest single buy, per cycle. The matching sell is capped by the seller's holdings.
  • Min/Max SOL reserve (Advanced) — random reserve each buyer keeps.
  • Min/Max delay between cycles; Max cycles (0 = until sellers are empty).
  • Max supply per wallet — skips buyers at the ceiling; a mounted plan sets it.
  • Advanced: Jito tip, slippage, confirm timeout, max consecutive errors.
After a bundle

Add a Bundle and a Hand Switcher in the wizard, click Use bundle wallets as sellers, pick separate funded buyers, enable autostart, and set a finite cycle limit for a test.

  • Max supply per walletnumberdefault 0 %0–100 %
    Hard ceiling: a wallet already holding this % of supply is skipped instead of buying more. A mounted supply plan sets it. 0 = off.

  • Simulatetoggledefault off
    Check the task without sending transactions or spending funds.

Hand Switcher trades for real — there's no Simulate on the Tasks page. Added to a launch, it rehearses with the launch's Simulate.

Non-SOL quotes may need conversion transactions, kept in the same atomic bundle. A rehearsal checks each transaction on its own and can't carry a prior transaction's new quote balance forward, so a split route may report an unfunded leg even when the live atomic bundle would execute.
