We've added HyperEVM mainnet to the Moralis Streams API. You can now listen to real-time blockchain activity on HyperEVM - perfect for notifications, indexing, and on-chain automation.

What you get​

  • 🔔 Real-time events: contract logs, native & token transfers, NFT mints/transfers, wallet activity
  • ⚡ Low-latency webhooks with retries & idempotency
  • 🧩 Works with your existing stream filters and ABIs
  • 📈 Scales with your traffic

How to use​

  1. Create or update a Stream in your dashboard or via API.
  2. Select HyperEVM (mainnet) as a chain.
  3. Add your address filters/ABIs and save - webhooks start flowing instantly.

Great for​

  • Alerting users on transfers or mints
  • Powering indexers/search for your dapp
  • Triggering off-chain workflows from on-chain events

If you're already streaming other chains, just add HyperEVM to that stream (or create a new one) and you're set. 🚀

We've made Streams more cost-efficient!

  • 🔄 Pricing has been reduced from 50 CUs per record → 10 CUs per record
  • 📉 This means up to 5x more data for the same cost
  • 🚀 Applies to all chains and all Streams starting today

No action needed on your end - your existing Streams are already benefiting from the new pricing.

Up until now, Streams and API pricing have been separate. And all accounts on Moralis have had a certain number of Stream records included in their plan.

Today we're announcing the streamlining of Streams and API pricing. Both Streams and API moving forward will be priced in Compute Units.

Each Streams record will have a fixed price of 15 Compute Units. Which means that the amount of Streams records included in your plan will be a lot higher than today for the vast majority of clients.

The change will go live on October 16th. For all Streams user it will be a seamless transition without the need for any action on their side.

As an example, a Pro plan user who solely uses Streams would go from having 50,000 records included in their plan to have over 660,000 records included.

A business plan user who solely uses Streams would go from having 50,000 records included to have over 2.3 million records included.

Any separately purchased Streams plan will be compensated with the same amount of Compute Units being added to their Moralis plan.

If you have any questions about this transition please contact our 24/7 support at hello@moralis.io.

nftApprovals in webhooks becomes deprecated. A new list nftTokenApprovals is introduced. The new field will not split between ERC1155 and ERC721 instead it unifies the NFT Approvals.

  ...,
  nftTokenApprovals: [
   {
     transactionHash: "0xf0c7542c73e2d26cc0b249da63426643263463463646345",

Stream blockchain data into your backend via webhooks. Ethereum, Polygon, Avalanche, BNB Chain, Fantom, Cronos and all testnets are supported. We’re working on adding more networks every day! 🚀🎉

Moralis’ Streams API is the latest addition to the Moralis API suite (which includes our popular NFT API, EVM API, Solana API and more). With this new API, you can get real-time on-chain events sent directly to your backend via webhooks! What does this mean? It means seamless access to:

  • See every time a specified address receives, sends, swaps, stakes, or burns assets
  • Track when battles or events start in your Web3 game or metaverse
  • Monitor when an address joins your token sale
  • That’s not all! In true Moralis style, the Streams API is fully configurable. Set custom filters to capture the exact on-chain event you need for your project as soon as they fire.

Moreover, each event comes enriched with important data, such as “tokenName”, “tokenSymbol”, “contractType” (for NFTs), “decimals” (for ERC-20 tokens), and more enriched data events will be added soon.
