# Chainstack updates: February 22, 2023

> Harmony moves from devnet to testnet for a better developer experience, and you can now manually retry failed Chainstack billing payments via crypto or card.

* **Billing**. You can now settle your failed payment by manually retrying either via topping up your crypto balance or via paying directly from your credit card.
