The CLVM currently supports BLS12-381 group 1 point operations which it
uses to support taproot which I think is enough to support PTLCs but
obviously isn't compatible with secp. In the future there will likely be a
soft fork to include a complete set of BLS12-381 operations mostly to
support ZK implementation.
