# Chainstack Self-Hosted v2.14.0: July 29, 2026

> Tempo Mainnet and Tempo Testnet are now available as deployment targets.

This release adds Tempo Mainnet and Tempo Testnet as deployment targets, running as non-validator nodes in archive mode.

## Tempo support

Tempo Mainnet and Tempo Testnet are now available as deployment targets, running as non-validator nodes in archive mode.

* Tempo Mainnet — chain ID 4217, explorer at [explore.tempo.xyz](https://explore.tempo.xyz)
* Tempo Testnet — chain ID 42431, explorer at [explore.testnet.tempo.xyz](https://explore.testnet.tempo.xyz)
* Endpoints — HTTP and WebSocket JSON-RPC, with the `eth`, `net`, `web3`, `debug`, and `trace` namespaces enabled

Testnet carries considerably more history than mainnet — provision about 1,100 GiB of storage for Testnet against 70 GiB for Mainnet. See [System requirements](/docs/self-hosted/requirements) for the full specification and [Supported clients and protocols](/docs/self-hosted/supported-clients-and-protocols) for the deployment catalog.
