Oh! Is it finally deployed on a testnet? I’ve been waiting for that, as that is a good indication the spec of likely done changing. Plus it enables trying it out to test it. :)

Initially this will be available on signer._authorization() and once official, will be signer.authorization().

@ricmoo it's deployed on Pectra Devnet, Odyssey and a few others. Looking forward to this

Thanks! Yes, I have a local implementation (in BaseWallet and Transaction) ready to release on the 24th once I can test it out. :)

@ricmoo let me know if this requires any contribution, as I've already tested this out on mekong
