Summary
The user is looking for an example of how to pass account keys to a transaction in Go, noting that the previous method using flow.NewTransaction() and AddRawArgument() is no longer working due to changes in the Cadence API in C1.0. They mention that RLP encoded account keys are obsolete and suggest that if the utility still exists in the Go SDK, it should be removed. The recommended solution is to pass the Cadence account.keys.add parameters individually instead of using a single RLP encoded key argument.
