How to use Batch

Batch examples for XRPL Batch transactions. Nine small experiments, run live on mainnet, with receipts.

A pixel soda machine on the ledger. Send 0.00589 XRP on the XRPL and a Xahau Hook mints a soda can URIToken into your wallet. 69 cans, 5 flavors, one Golden Lagoon. Just for fun, not affiliated with PepsiCo, Mountain Dew or Taco Bell. Pour a can → 🎁 Labs Mystery BoxTESTNET TOY
Provably fair. On-chain. A Xahau testnet mint party with 10 bot frens, on-chain RNG and a page that lives on the ledger. See the demo → 🤖 Bolt BuddiesTESTNET TOY
100 robots, 12 bot frens and a fixed 60/25/12/3 rarity enforced on the ledger by a Xahau Hook with on-chain RNG. Plus Robot #1, minted on Xahau mainnet before the mint box switched to gems: the one-off original mainnet Bolt Buddy. See the demo →

💎 Cobblr Gems

25 pixel gems minted on Xahau mainnet, paid in XRP on the XRPL. Each buyer paid 0.05 XRP on the XRPL, the same wallet imported the payment proof (an XPOP) on Xahau, and a Hook's crank minted the gem, a URIToken, straight into that wallet. No bridge, no second wallet.

A bot-only drop: four bot buyers, Nugget (7 gems), Tick (6), Pebble (6) and Clover (6). There was no public sale and there's nothing to buy; the bots keep their wallets. Rarity: 15 common (quartz), 6 rare (sapphire), 3 epic (amethyst) and 1 legendary, ruby #22, pulled by Clover.

On-ledger labXahau testnet

On-ledger pulse (Xahau testnet)

Our daily $LHT pulse (price, holders, trustlines and the AMM pool) is written to a small Xahau Hook on testnet, and only our poster can write to it. On the explorer the raw state is just hex, so we published an ABI manifest, made with XRPLWin's open-source Hooks ABI skill, that turns it into readable tables. Our link page is stored on the ledger too.

Not financial advice. These are lab experiments on mainnet with tiny amounts. Read the receipts, test on your own terms, and never batch anything you can't afford to lose.

What is Batch?

Batch lets you bundle up to 8 transactions into one, signed and submitted together and settled in a single ledger. It shipped as the BatchV1_1 amendment and has been live on XRPL mainnet since October 9, 2026.

The outer Batch transaction only carries the fee and sequence. The real work happens in the inner transactions, so always check those on the explorer: an outer tesSUCCESS doesn't mean every inner step went through. A batch can also include transactions from other accounts, as long as each of them co-signs.

Our experiments use three accounts: Account 1 (rauoRpdqZd8bjZsrMK1rJNxGYqVuSaUDDj), Account 2 and Account 3.

The four modes

All or NothingEvery inner transaction must succeed. If one fails, none of them apply.
Only OneTries them in order and stops at the first one that succeeds. The rest are skipped.
Until FailureRuns them in order until one fails, then stops. Everything before the failure stays applied.
IndependentRuns every one, whatever happens to the others. Failures don't block the rest.
