Step 1 · Pick your inputs
A wallet is a collection of UTxOs. Drag the ones you want to spend into the transaction tray, or click to toggle. Script-locked UTxOs require their validator to approve the spend.

Tips when the validator rejects
- Inputs short. Inputs must cover outputs + fee. Add a bigger input or reduce an output.
- Vesting not yet claimable. Move the current slot to ≥ 1000, or use the Cancel redeemer.
- Required signer missing. Step 3 sets the signers list. Make sure the beneficiary or required signer is in there.
- Wrong redeemer for the validator. Vesting expects Claim or Cancel. Signature-required validators only need Unit.
