// See https://github.com/cosmos/cosmos-sdk/issues/15317 for description of bug.
// Basically, in cosmos SDK, there is an account address cache that will ignore the bech32 prefix setting.
// This will cause the AccAddress.String() to print out unexpected prefixes.
// If this function fails you are on an unsafe SDK version that should NOT be used with the relayer.
