CAT Token Transaction Limits
For a CAT Token protocol transaction, the maximum number of inputs is 6
, and the maximum number of outputs is also 6
.
Since we need to calculate the txid of the previous transaction, we must ensure the previous transaction’s data is within 520
bytes.
This is because the maximum byte limit for an element on the Bitcoin Virtual Machine (BVM) stack is 520. The corresponding constant name is MAX_SCRIPT_ELEMENT_SIZE
.
