Important Notes

1. After obtaining the unsigned PSBT, the user must sign it within 30 seconds.

2. The checksum field should use the value from the previous request, even though the field name may differ.

3. Use the same address for both btc_address and address.

4. For user_public_key, provide the parameter as public_key:public_key for a wallet with one address, or btc_public_key:ordi_public_key for a wallet with two addresses.
