TRON Testnet (Shasta) – Performance Expectations

The Tron Testnet used by Tatum is Shasta, a public test network operated and maintained by the Tron Foundation. Unlike many other blockchains, Shasta nodes cannot be run by external parties. This means that all providers, including Tatum, rely on the same public Shasta infrastructure

What This Means For You

Intermittent errors are expected: At present, neither Tatum nor any other third party can run Shasta nodes. Only the Tron Foundation can. As a result, requests may occasionally fail with errors such as:
```
{"id":1,"jsonrpc":"2.0","error":{"code":-16500,"message":"Invalid response from upstream"}}
```
Error rates can vary: In practice, some users may encounter failure rates when calling methods on the Shasta network. These failures typically resolve on retry.
Retries are recommended: If you are testing on Shasta, implement automatic retry logic in your application for failed requests. This is considered best practice across all chains.
Not production-grade: Shasta is intended for testing only. It does not guarantee uptime, performance, or stability.

Official Reference

From Tron developer documentation:

“The Shasta test network does not support adding new nodes run by anyone.”
