1、关于 cat_20_output_to_split，需要查询对应地址的对应 cat20 的 utxo，找到想拆分的 utxo，然后用对应 utxo 的 txId 和 outputIndex 进行拼接

查询地址参考(请替换 tokenIdOrTokenAddr 和 ownerAddrOrPkh)

• testnet url
• mainnet url

拆官方的 cat20

如果你有使用官方的 cat20 充值的接口，那么你也可以使用这个接口拆分你充值进来的 cat20。

• 首先调用充值接口 /create_deposit_cat20_psbtv2的时候，你可以设置参数not_split:true。

• 充值成功之后，/create_deposit_cat20_order_by_psbt会返回 receiver_addr和txid。

这个时候你可以用如下参数来调用拆分接口

参数示例

{
  // 这两个参数请默认写为true
  "is_ofc_token": true,
  "is_average_split": true,

  // 这是你用于充值的钱包
  "user_addr": "bc1psx048lgxx9qlgnw2yjn6vw7ndz07f5rdlfxraqpxkr84tqa7670sagd4k8",
  "user_pubkey": "03c22e2f276e66c24e515b24a0c6bcf53852b046b31bbaf98d3f3075c005729691",

  // 准备拆分的代币（和你充值的代币名称保持一致）
  "tick": "dog:b1071ae617c66050d518587f67564885ca1a618b387a15f84001e3fa244ef3d6_0",

  // 这个是充值接口返回的 txid + :1（:1是固定的）
  "cat_20_output_to_split": "3c92ae8ce3fd6377ac9316a28ded9ca5daef835dd3cf2613b8047c1ee9bbf530:1",

  // 这是充值接口返回的receiver_addr
  "token_addr": "bc1plsm7wgedgkguhk5xyllhyml2zstu0z7zs353hq7h6jlvu5puf4sqhc2l5t",

  // 数量请大于4
  "split_num": 5,

  "fee_rate": 9
}
