I've said before that a working litecoin covenant wallet would put a lot of concerns to rest

- Potential for Spam Transactions

While OP_CTV is designed to create more efficient transaction types, there's a risk that it could be misused to generate spam transactions, potentially clogging the network1. Adversaries might exploit this to conduct denial-of-service attacks on the Bitcoin network.

- Recursive Covenant Concerns

Although OP_CTV itself is non-recursive, its implementation could potentially enable the creation of complex scripts that lead to recursive covenants2. This could result in transactions that reference each other in circular chains, consuming network resources and causing scalability issues.

- Fragmentation of the Ecosystem

There's a risk that OP_CTV could lead to the creation of "walled gardens" within the Bitcoin ecosystem1. This could potentially fragment the network, with certain transactions only permitted within specific parameters, departing from Bitcoin's open and permissionless nature.

As usual
