OPALE

Sweep

A sweep is a bulk-buy at the floor: you set a budget and a max unit price, and OPALE buys the cheapest listings first until either limit is hit. It’s the fast way to scoop a token without specifying the amount yourself.

The button flow

Section titled “The button flow”

  1. From the home screen tap 🛒 Buy, then tap 🧹 Sweep floor. Sweep is also reachable directly from any token’s listings view.

    Sweep menu with ticker chips and Browse all.
    Sweep menu with ticker chips and Browse all.

  2. Pick a ticker. Tap one of the chips, or 🔎 Browse all to search.

  3. Set a budget. Two ways:

    • Tap a 1-tap preset (⚡ $50 / ⚡ $100 / ⚡ $500) — only shown when the floor is known; cap is auto-set to floor +10 %.
    • Tap a currency button — 💵 Custom $, ⚡ Custom sats, or 🟠 Custom BTC — then type just the number (e.g. 100, 500000, 0.005). The unit you picked is locked, so a bare 100 is unambiguous.
    • Or type a full sweep like $100 @90, 0.001btc @90, or 1000000sats @90 (the currency must be included).

  4. Set a max unit price (in sats per token). Anything above this is excluded.

  5. Read the sweep quote. OPALE shows the listings it picked, the total tokens you’d receive, the total BTC cost, the 5 % fee, and your change.

  6. Tap ✅ Confirm Sweep. OPALE rebuilds and signs each transaction and broadcasts the batch.

    Sweep quote: depth (e.g. 3/12 listings under cap), total BTC, fee, change, Confirm Sweep + Cancel.
    Sweep quote: depth (e.g. 3/12 listings under cap), total BTC, fee, change, Confirm Sweep + Cancel.

The Confirm screen has ❌ Cancel alongside ✅ Confirm Sweep, and a 💰 Wallet button if you need to top up before confirming.

/sweep LOL $100 @90

Spend up to $100 on LOL, paying no more than 90 sats per token. Accepted budget forms: $100, 100$, 0.001btc, or 1000000sats — always include the currency. A bare 100 is read as $100 (the small-decimal 0.001 shorthand is read as BTC), but explicit is always safer.

How it picks listings

Section titled “How it picks listings”
  1. Sort cheapest-first on WhiteNode.
  2. Filter to listings within your cap. Anything above is excluded immediately.
  3. Add until adding the next one would cross your budget. OPALE accumulates BTC cost as it goes and stops the moment the next listing would push the total over.
  4. Show the quote. Total tokens, total cost, fee, change.
  5. On confirm, broadcast each transaction. Distributed locks on every listing prevent OPALE from racing itself across users.

Honesty about races

Section titled “Honesty about races”

Sweeps are made of many listings. Each listing is its own transaction, and any individual one can be raced by another buyer. OPALE handles this by:

  • Locking every listing in the batch before broadcasting. Two OPALE users sweeping the same listings can’t both win — the lock decides who gets which.
  • Stopping early on race-loss. If a listing falls out (raced, cancelled, or fails to broadcast), OPALE moves on; it doesn’t promise a fixed total.

The total tokens you receive is at most what was quoted. If listings race away during broadcast, your sweep ends earlier than expected and you keep the unused BTC.

When sweep shines

Section titled “When sweep shines”
  • Floor scooping — clearing the cheapest listings during a quiet moment.
  • Predictable budget — you know exactly the maximum you can spend.
  • Long-tail tokens — a thin orderbook fills in one go instead of dozens of round-trips.

When 🛒 Buy is better

Section titled “When 🛒 Buy is better”
  • Targeting a specific quantity — LOL 1000 50000 says “exactly 1 000, no more, no less.”
  • Tight cap with patience — for a single listing at a specific price, a limit buy is closer to what you want.
