Choice of relayer to connect any heterogeneous blockchain to a Cosmos chain

[MiguelRocha2001]

Hello.

I am trying to connect a blockchain to the IBC ecosystem, by implementing the IBC protocol on an external state-machine. Now, I need a relayer, so when the state-machine produces IBC packets, they need to be relayed by the relayer, among other things, such as receiving IBC packets, sending and submitting proofs, make the IBC handshake, etc.

What options do I have? Can I use your relayer? Hermes and Relayer-Go seem to be supported only for Comos chains.
Maybe Hyperspace can be used?

In particular, I want to o connect an heterogeneous blockchain (where the IBC state machine will be handled by external validators), to any Comos chain, such as Gaia.

If anyone could help me on this matter, I would be appreciated.

Thanks in advance.
