 The IBC Apps repo has [`ibc-hooks`](https://github.com/cosmos/ibc-apps/tree/main/modules/ibc-hooks) middleware, which has similar functionality and the Memo structure is compatible with the one defined here. IBC App hooks only support cosmwasm procedures: the instruction is defined in the `Memo.wasm` field and fallback is fully handled by the CW contract. This implementation is compatible with IBC Apps: in the future we can support IBC Apps `wasm` hooks, without breaking our `Memo` struct.
 
+### Limitations
+
+- The current protocol requires that the IBC receiver is same as the "operator" (supplier, liquidator) in the `Memo.messages`.

 ## IBC ICS20 Quota
 
 Hack or lending abuse is impossible to stop once the funds leave the chain. One mitigation is to limit the IBC inflows and outflows and be able to stop a chain and recover the funds with a migration.
