This is a sample smart contract that connects to the Translucent Oracle on Goerli and retrieves a dynamic list of strings from a JSON API.

| Below are a bunch of resources that help you grok error handling in Go. | |
| * Listen to Go Time Podcast #16, specifically the parts on error handling https://changelog.com/gotime-16/ | |
| * Read http://dave.cheney.net/2016/04/27/dont-just-check-errors-handle-them-gracefully | |
| * Read http://dave.cheney.net/2016/06/12/stack-traces-and-the-errors-package | |
| * Use the errors pkg for some syntactic sugar... https://godoc.org/github.com/pkg/errors | |
| Use Dave Cheney's "rules"... either handle the error locally and then never again (e.g. log to stderr) OR | |
| pass the error up the call stack. Consider annotating the error... errors.Wrapf(err, "Unable to access %s upload folder", account) | |
| before passing it back up the stack. |
