I write a easy taproot-based script in bitcoinjs, like:
<pk1> OP_CHECKSIG <pk2> OP_CHECKSIGADD <pk3> OP_CHECKSIGADD OP_2 OP_EQUAL
It must be a 3-2 threshold account, that require 2 signature. Nonetheless, it truly required 3 signature, if we solely signal it with 2 keypair, it’ll happen:
Operation not legitimate with the present stack dimension
So how do I in a position to spend this taproot tackle, with solely 2 legitimate keypair?
