microservice-key-rotation
AWS Lambda function responsible for updating the Fluidity contract oracle addresses. Generates the keys, updates AWS parameters, then pushes a log to S3. For each token, the log contains previousKey.Sign(newAddress), where newAddress is a 20 byte address that's been left padded with zeros to be 32 bytes long. Additionally creates and signs transactions to transfer the Ether balance from the old to new oracles, then uploads them internally to Discord.
