We're excited to announce the launch of our new spam detection feature to EVM Streams API!

Property called possibleSpam for the following items in the webhook: erc20Transfers, erc20Approvals, nftTokenApprovals, and nftTransfers. This property can be true or false,depending on whether the contract address is associated with spam, phishing attempts, or suspicious activities.

Check out our docs for more information about this feature including which endpoints it's active on.

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.

Stream blockchain data into your backend via webhooks. Ethereum, Polygon, Avalanche, BNB Chain, Fantom, Cronos and all testnets are supported. We鈥檙e working on adding more networks every day! 馃殌馃帀

Moralis鈥 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鈥檚 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 鈥渢okenName鈥, 鈥渢okenSymbol鈥, 鈥渃ontractType鈥 (for NFTs), 鈥渄ecimals鈥 (for ERC-20 tokens), and more enriched data events will be added soon.
