# Chainstack Self-Hosted v2.16.0: July 30, 2026

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

This release adds Plasma Mainnet and Plasma Testnet as deployment targets, running Reth for execution alongside the PlasmaBFT consensus client as non-validator nodes in full mode.

## Plasma support

Plasma Mainnet and Plasma Testnet are now available as deployment targets. Each deployment runs two components — Reth for execution and the PlasmaBFT consensus client — as non-validator nodes in full mode.

* Plasma Mainnet — chain ID 9745, explorer at [plasmascan.to](https://plasmascan.to)
* Plasma Testnet — chain ID 9746, explorer at [testnet.plasmascan.to](https://testnet.plasmascan.to)
* Endpoints — HTTP and WebSocket JSON-RPC, with the `eth`, `net`, `web3`, `txpool`, and `debug` namespaces enabled

Both networks sync from genesis over the network's public peers rather than restoring from a snapshot. Provision about 350 GiB of storage for Mainnet and 250 GiB for Testnet across the two components. 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.
