During latest tests, we realized smoldot can't make transfer on parachain anymore with the following message:
[tx-service-shibuya] Failed to validate transaction 0xb4f0…bff4: Error in call proof: UnusedProofEntry

The connection is well established with relay (tokyo) and para (shibuya).
Transfers work for any relay chain.
Transfer don't work with parachain.

How to reproduce

Shibuya tokens can be obtained just requesting the faucet here: https://portal.astar.network/shibuya-testnet/assets

I will check it out 👍

For what it's worth, a similar issue was found two months ago (#154) and fixed by paritytech/substrate#13284

If you don't have paritytech/substrate#13284 in, then unfortunately that'd be the cause.

Thanks @tomaka so that may be it, Astar is not yet uplifted to polkadot-v0.9.39 including this fix.
We'll uplift soon and check the issue again as soon as upgrade is made.

For what it's worth, this was a bug in Substrate that happens when you transition the chain to state_version = 1. This is most likely why it used to work in the past but now no longer.
