Running master (which has PR#21500 merged), then the above can be
done with:
1. create a descriptor wallet
bitcoin-cli -signet -named createwallet wallet_name=descwallet descriptors=true load_on_startup=true
2. get the associated bip32 tprv private key
TPRV=$(bitcoin-cli -rpcwallet=descwallet -signet listdescriptors true | jq '.descriptors | .[].desc' | sed 's/^.*(//;s/[)/].*//' | uniq | head -n1)
(This step requires PR#21500 to extract the wallet's tprv; you'll need to
be running an updated version of bitcoin-cli here as well as bitcoind. You
could also generate the tprv some other way.)
3. construct the taproot descriptor per BIP 86
DESC="tr($TPRV/86'/1'/0'/0/*)"
CHK="$(bitcoin-cli -rpcwallet=descwallet -signet getdescriptorinfo "$DESC" | jq -r .checksum)"
4. import the descriptor
bitcoin-cli -rpcwallet=descwallet -signet importdescriptors "[{\"desc\": \"$DESC#$CHK\", \"active\": true, \"timestamp\": \"now\", \"range\": [0,1000], \"next_index\": 1}]"
5. get an address
bitcoin-cli -rpcwallet=descwallet -signet getnewaddress '' bech32m
You can then use the signet faucet to send a few million ssats to that
address directly.
Same stuff works with testnet, though I'm not sure if any testnet faucets
will accept bech32m addresses directly.
This is all a bit deliberately cumbersome prior to taproot activating on
mainnet; once that happens and PR#22364 is merged, you'll only need to
do steps (1) and (5).
Cheers,
