@Rajil1213 these are the only ones missing here apart from the superblocks that we're not backporting.

Looks good. But since we're at it, we might want to add a few more RPCs that are relevant to the bridge for the Testnet I impl:

• submit_package (for CPFP in core 28.0)
• gettxout(to check if a particular utxo exists)

This is not too urgent at the moment though so feel free to create separate tickets for these if there are other tasks of higher priority that you might want to be doing instead.

[storopoli]

@bibek thanks for the review. I also added the submit_package RPC.

EDIT: this PR is really easy to review if you check the commits, they do follow a very a good logic and are atomic in a sense.

[bewakes]

Looks good, minor query. And a very nice commit history indeed !

[Rajil1213]

Nice work! Requesting a few additional test cases though.

@bewakes and @delbonis just look at the last two commits.
These changes were needed to support One Parent One Child Relay (1P1C), see the first example in https://bitcoinops.org/en/bitcoin-core-28-wallet-integration-guide/
