# Supported Networks Source: https://docs.chain.link/cre/supported-networks-ts Last Updated: 2026-09-18 > 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 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. ## Mainnets | Network | CLI | Go SDK | TS SDK | | -------------------------------------------------------------- | -------- | -------- | -------- | | ADI Mainnet | v1.16.0+ | v1.10.0+ | v1.8.0+ | | Arbitrum One | v1.0.0+ | v1.0.0+ | v1.0.1+ | | Avalanche | v1.0.0+ | v1.0.0+ | v1.0.1+ | | Base | v1.0.0+ | v1.0.0+ | v1.0.1+ | | BNB Chain | v1.0.0+ | v1.0.0+ | v1.0.1+ | | Celo | v1.5.0+ | v1.6.0+ | v1.3.0+ | | Ethereum | v1.0.0+ | v1.0.0+ | v1.0.1+ | | Gnosis Chain | v1.5.0+ | v1.6.0+ | v1.3.0+ | | Hyperliquid Mainnet | v1.7.0+ | v1.7.0+ | v1.4.0+ | | Ink | v1.5.0+ | v1.6.0+ | v1.3.0+ | | Jovay | v1.3.0+ | v1.4.0+ | v1.3.1+ | | Linea | v1.5.0+ | v1.6.0+ | v1.3.0+ | | Mantle[\*](/cre/concepts/finality-ts#using-confidence-levels) | v1.5.0+ | v1.6.0+ | v1.3.0+ | | MegaETH | v1.5.0+ | v1.6.0+ | v1.3.1+ | | Monad | v1.29.0+ | v1.17.0+ | v1.18.0+ | | OP Mainnet | v1.0.0+ | v1.0.0+ | v1.0.1+ | | Pharos | v1.3.0+ | v1.4.0+ | v1.3.1+ | | Plasma | v1.5.0+ | v1.6.0+ | v1.3.0+ | | Polygon[\*](/cre/concepts/finality-ts#using-confidence-levels) | v1.0.0+ | v1.0.0+ | v1.0.1+ | | Scroll[\*](/cre/concepts/finality-ts#using-confidence-levels) | v1.5.0+ | v1.6.0+ | v1.3.0+ | | Sonic | v1.5.0+ | v1.6.0+ | v1.3.0+ | | World Chain | v1.0.11+ | v1.2.0+ | v1.0.9+ | | XLayer | v1.3.0+ | v1.4.0+ | v1.1.3+ | | ZKSync Era | v1.0.6+ | v1.1.3+ | v1.0.7+ | \* Safe and finalized reads are not reliably supported on these networks.

See [Finality and Confidence Levels](/cre/concepts/finality-ts#using-confidence-levels). ## 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 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).
