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.
