# Streams Supported Chains

> Blockchains supported by Moralis Streams for real-time onchain event and activity monitoring.

### Streams Supported Chains

Moralis Streams provide **real-time onchain data delivery** via webhooks, allowing you to react to blockchain activity as it happens.

Streams support a subset of chains where:

* Real-time indexing is available.
* Finality and reorg handling meet production requirements.

Use the tables below to see which chains are supported for Streams and what types of events can be monitored.

### Non-EVM Chains

Bitcoin and Solana streams have their own API groups and chain-specific configuration. See [Bitcoin Streams](/streams/bitcoin-streams) and [Solana Streams](/streams/solana-streams) for details.

| Chain Name      | Type    | Chain ID         | Streams Supported | Confirmation Threshold |
| --------------- | ------- | ---------------- | ----------------- | ---------------------- |
| Bitcoin Mainnet | Mainnet | `btc-mainnet`    | ✓                 | 2 blocks               |
| Solana Mainnet  | Mainnet | `solana_mainnet` | ✓                 | 100 slots              |

<Note>
  `Internal Txs` is an EVM-only concept and does not apply to Bitcoin or Solana. On Solana, the time unit is the **slot** rather than the block — most slots produce a block.
</Note>
