+
+- research ICA
+- integrated ICA in evmos - tested interchain bank transfers and it works
+- designed ICA precompile in Ethermint, to be used for bridges
+
+```solidity
+interface InterchainAccountsPrecompile {
+    function emitTx(bytes32 chainId, bool storeResponse, bytes memory input) external returns(bytes memory success);
+    function getResponse(bytes32 txHash) view external returns(bytes memory response, bytes memory error);
+}
+```
+- tedious manual testing and debugging, a lot of trial and error work
+- integration tests were started
