# Supported Networks
Source: https://docs.chain.link/cre/supported-networks-ts
Last Updated: 2026-07-13

> For the complete documentation index, see [llms.txt](/llms.txt).

This page lists networks supported by CRE workflows, along with the minimum CLI and SDK versions required for each network. CRE supports two [chain families](/cre/capabilities#chain-families): EVM-compatible chains and Solana.

> **TIP: Check chains enabled for your tenant**
>
> The tables below show minimum version requirements for each network. To see which chains and mock forwarder addresses
> are enabled for **your** organization, run [`cre workflow
>   supported-chains`](/cre/reference/cli/workflow#cre-workflow-supported-chains) after `cre login` (or with `CRE_API_KEY`
> set). Use `--output json` for machine-readable output.

## Version Requirements

Network support depends on your CLI and SDK versions. The tables below show the minimum versions required for each network.

- **New projects:** Run `cre update` to get the latest CLI, which includes compatible SDK versions.
- **Existing projects:** You may need to update your SDK dependency. See [Updating Dependencies](/cre/reference/project-configuration-ts#5-updating-dependencies) for instructions.

## Forwarder Addresses

For EVM forwarder contract addresses and chain names, see the [Forwarder Directory](/cre/guides/workflow/using-evm-client/forwarder-directory). Forwarder addresses are used when building consumer contracts that receive workflow reports onchain. Learn more about [EVM Onchain Write](/cre/guides/workflow/using-evm-client/onchain-write/overview-ts).

Run [`cre workflow supported-chains`](/cre/reference/cli/workflow#cre-workflow-supported-chains) anytime to list the chains and mock forwarder addresses currently enabled for your tenant.

## Solana Networks

Solana support is currently **write-only**. Read and Log Trigger capabilities are in development. Solana write requires
**CRE CLI v1.24.0 or later** (`cre version` / `cre update`).

| Network        | CLI      | Capabilities | Chain Selector         |
| -------------- | -------- | ------------ | ---------------------- |
| Solana Mainnet | v1.24.0+ | Write        | `124615329519749607`   |
| Solana Devnet  | v1.24.0+ | Write        | `16423721717087811551` |

In TypeScript, use `SolanaClient.SUPPORTED_CHAIN_SELECTORS['solana-mainnet']` (returns `124615329519749607n`) or pass the selector directly as a `bigint`.

For Solana forwarder program and state account addresses (simulation and production), see the
[Solana Forwarder Directory](/cre/guides/workflow/using-solana-client/forwarder-directory-ts).

Learn more in the [Solana Chain Interactions guide](/cre/guides/workflow/using-solana-client/overview-ts).
