* add helpers & tests for erc20 eth_call query & transfer * make encoding config public * add evm client & raw evm signer to account * test eip712 signing and broadcast * update for cosmos v46 * update kvtool * temporarily disable ibc tests & skip shutdown * disable all but eip712 test and massively simplify * add EIP712 tx builder & setup basic MsgSend test * reenable all tests * add eip712 test that deposits erc20 into earn * update kvtool to master branch
