Token Distribution Alerts.
Engage users with live webhook feeds for loyalty token and utility transfers.
Keep your users updated in real time. Standardize native and ERC-20 transfer event structures across every supported chain to power client-facing dashboards and activity feeds.
Why custom RPC listening loops break in production
Web3 apps, loyalty platforms, and mobile wallets need to display real-time feeds of reward transfers, utility token mints, and token distributions. Creating these feeds requires parsing raw blockchain log topics, decoding ABI events, and filtering them by user address. Doing this at scale for thousands of concurrent users requires building and scaling custom indexers, running stateful databases, and managing persistent websocket connections, which strains server resources and degrades application performance.
How Blockferry Solves It
Blockferry normalizes token transfers (ERC-20, ERC-721, and ERC-1155) into a single unified JSON schema. Using our SDK Router, you can define clear event-routing logic to dispatch live updates to frontend dashboards, notification servers, or pub/sub clients like Pusher. By offloading event filtering and ABI decoding to Blockferry, you can build responsive, real-time user feeds with zero indexing infrastructure.
Build it with the SDK & CLI
| 1 | import { BlockferryRouter } from "@blockferry/sdk"; |
| 2 | |
| 3 | const router = new BlockferryRouter(); |
| 4 | const LOYALTY_TOKEN = "0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984"; |
| 5 | |
| 6 | // Route loyalty token transfers to user dashboard feed |
| 7 | router.onTokenTransfer(LOYALTY_TOKEN, async (event) => { |
| 8 | await pusher.trigger(`user-${event.toAddress}`, "transfer", { |
| 9 | from: event.fromAddress, |
| 10 | amount: event.valueInDecimals, |
| 11 | token: event.tokenSymbol, |
| 12 | txHash: event.txHash, |
| 13 | }); |
| 14 | }); |
| 15 | |
| 16 | // Also catch native transfers for the same users |
| 17 | router.onNativeTransfer(async (event) => { |
| 18 | await pusher.trigger(`user-${event.toAddress}`, "transfer", { |
| 19 | from: event.fromAddress, |
| 20 | amount: event.valueInDecimals, |
| 21 | token: "ETH", |
| 22 | txHash: event.txHash, |
| 23 | }); |
| 24 | }); |
| 25 | |
| 26 | await router.handle(payload); |
