ADA batch tools

Cardano batch tools: balances and one-to-many payments. Cardano is UTXO-based, so a single transaction can pay many recipients for one fee. Transactions are built and signed in your browser; the server only reads the chain and relays.

How to use

  1. Balance mode takes addresses only, no keys
  2. Multi-send: paying address, its payment key, then one "address amount" per line
  3. Submit, then follow the transaction on Cardanoscan

FAQ

Where does the key come from?
Derive one with the wallet generator (pick Cardano), or paste your wallet's exported payment key (bech32 ed25519_sk1…). It is used in this page only.
Why does one transaction pay everyone?
A UTXO transaction can carry many outputs, so a multi-send is naturally one transaction and one fee — unlike account-model chains.
What if the address has many UTXOs?
A transaction can only hold so many inputs, so the server hands the browser the 40 largest UTXOs for coin selection.
