Split paymaster cells

The example/paymaster.ts demonstrates how to use @rgbpp-sdk/ckb SDK to split multiple cells and you can set the parameters as blow:

• receiverAddress: The receiver ckb address
• capacityWithCKB: The capacity(unit is CKB) of each cell, for example: 316CKB
• cellAmount: The amount of cells to be split

cd packages/ckb && pnpm splitCells

RGB++ xUDT Transfer on BTC

The method genBtcTransferCkbVirtualTx can generate a CKB virtual transaction which contains the necessary inputCells/outputCells for RGB++ xUDT transfer and the commitment to be inserted to the BTC tx OP_RETURN.

export interface BtcTransferVirtualTxResult {
  // CKB raw transaction
  ckbRawTx: CKBComponents.RawTransaction;
  // The rgbpp commitment to be inserted into BTC op_return
  commitment: Hex;
  // The needPaymasterCell indicates whether a paymaster cell is required
  needPaymasterCell: boolean;
  // The sum capacity of the ckb inputs
  sumInputsCapacity: Hex;
}
