Alex 0ddaf1c5cc Fix incorrect getRemoteInterchainAccount derivation (#2446 ) ### Description A minor change to how we deploy InterchainAccountRouter's and a fix for remote ICA address derivation. The fix is outlined clearly in #2383 by Nam but essentially by assigning the `implementation` & `bytecode` variables in the constructor of `InterchainAccountRouter`, we are unable to correctly access them in `getRemoteInterchainAccount` if using a proxy. By moving initialisation of these variables to `initialize` we correctly store the values in the proxy storage, not the implementation storage. ### Drive-by changes The `InterchainAccountRouter` should no longer be used unproxied. ### Related issues - Fixes #2383 ### Backward compatibility No, new ICA deploy ### Testing - [x] Unit Tests --------- Co-authored-by: Yorke Rhodes <yorke@hyperlane.xyz>		1 year ago

Middleware Contracts

Interchain Accounts

An interchain account is a smart contract that is deployed on a remote chain controlled exclusively by the origin chain's deployer account. Interchain accounts provide developers with a transparent multicall API to remote smart contracts. This avoids the need to deploy application specific smart contracts on remote chains while simultaneously enabling cross-chain composability.

See IBC Interchain Accounts for the Cosmos ecosystem equivalent.

Interchain Query System

The interchain query system generalizes view calls to contracts on remote chains. It is a transparent multicall API that can be used to query remote smart contracts. This avoids the need to deploy application specific smart contracts on remote chains while simultaneously enabling cross-chain composability.
