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 and 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 |
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.
