A P2TR deal with encodes a public key utilizing Bech32m, which you’ll be able to straight decode. This public secret’s typically (as really helpful by BIP341) the results of taking a special key (referred to as “inner key”) and tweaking it with the dedication to a taproot script tree. The inner key shouldn’t be a part of the deal with so it can’t be decoded from it and is simply revealed when spending through the script path. Since protocols utilizing taproot often goal to make use of the important thing path each time attainable and a few even make the script path unspendable (e.g. BIP86), you won’t be able to find out the interior key for many taproot addresses (and even decide whether or not it exists in any respect).
