Hi Andreas,

You can construct a taproot-capable wallet in Bitcoin Core as follows:

* Have or create a descriptor wallet (createwallet RPC, with descriptors=true).

* Import a taproot descriptor (of the form "tr(KEY)"), as active descriptor (with active=true), where KEY can be a tprv.../* or any other supported key expression.

* Get a new address with addresstype=bech32m

I've also created one myself for testing: tb1p84x2ryuyfevgnlpnxt9f39gm7r68gwtvllxqe5w2n5ru00s9aquslzggwq

If you send testnet coins there email me an address, I'll return them.

Cheers,

Pieter
