 * `ConsensusClients`:
 This is a tuple of types that implement the `ConsensusClient` interface, it defines all the consensus algorithms supported by this deployment of the protocol.
 
-* `Mmr`:
- This type allows us to use mmr tree as an overlay for cheaper proofs for requests and responses instead of the merkle patricia trie proofs.

 Pallet ISMP offers a two different approaches to transaction fees.
 
 ### Unsigned
- 
+
 This essentially means all cross-chain messages received are executed for free as unsigned transactions. The upside to this is that it cannot be exploited as a spam vector, since the transaction pool will check if the submitted extrinsics are valid before they are included in the pool. This validity check ensures that the transaction can be successfully executed and contains valid proofs. Malformed messages or those with invalid proofs are filtered out by the transaction pool validation logic preventing unnecessary processing and potential network congestion.

 In this method, relayers and users will need to pay the native token for executing cross-chain messages. This is likely more preferrable but requires that the token be widely available.
