Below are the two alternative approaches you can use to transition seamlessly: ## Option 1: Use Jiffyscan Subgraphs Directly Jiffyscan provides subgraphs for querying blockchain data directly. Each subgraph corresponds to a specific EVM blockchain. ### Subgraphs | Network | Subgraph Name | Subgraph Endpoint | | ---------------- | ------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------- | | mainnet | [SUBGRAPH\_LINK](https://thegraph.com/explorer/subgraphs/FrwziBsTDBogUj57ts4U1kx5X5hDMkpX5STpUXphomyV?view=Query\&chain=arbitrum-one) | `https://gateway-arbitrum.network.thegraph.com/api/{API_KEY}/subgraphs/id/FrwziBsTDBogUj57ts4U1kx5X5hDMkpX5STpUXphomyV` | | matic | [SUBGRAPH\_LINK](https://thegraph.com/explorer/subgraphs/Ga4gCEvJGuu7Y2oXCbpa3R9KMNBXWYLg1kJPxnfeu5fb?view=Query\&chain=arbitrum-one) | `https://gateway-arbitrum.network.thegraph.com/api/{API_KEY}/subgraphs/id/Ga4gCEvJGuu7Y2oXCbpa3R9KMNBXWYLg1kJPxnfeu5fb` | | optimism | [SUBGRAPH\_LINK](https://thegraph.com/explorer/subgraphs/HxvH1S81KFam6J7etqtxngjLPhZMS5QcHKwPa7LVz1no?view=Query\&chain=arbitrum-one) | `https://gateway-arbitrum.network.thegraph.com/api/{API_KEY}/subgraphs/id/HxvH1S81KFam6J7etqtxngjLPhZMS5QcHKwPa7LVz1no` | | optimism-sepolia | [SUBGRAPH\_LINK](https://thegraph.com/explorer/subgraphs/AZR6rSiFMk3bTU4EhYKpTxYuAXNcU9m354nPbnp9JMcT?view=Query\&chain=arbitrum-one) | `https://api.studio.thegraph.com/query/45842/opt-sep-jiffy-scan/version/latest` | | arbitrum-one | [SUBGRAPH\_LINK](https://thegraph.com/explorer/subgraphs/4YM6vwSP4Mx38qXsVh6TFyrWrKgm7zvX4mFGPS2L6afk?view=Query\&chain=arbitrum-one) | `https://gateway-arbitrum.network.thegraph.com/api/{API_KEY}/subgraphs/id/4YM6vwSP4Mx38qXsVh6TFyrWrKgm7zvX4mFGPS2L6afk` | | avalanche | [SUBGRAPH\_LINK](https://thegraph.com/explorer/subgraphs/ALNXErAtAfjQU8TP39nitk6ej9ZtrDYmnXRYRdWiFuGZ?view=Query\&chain=arbitrum-one) | `https://gateway-arbitrum.network.thegraph.com/api/{API_KEY}/subgraphs/id/ALNXErAtAfjQU8TP39nitk6ej9ZtrDYmnXRYRdWiFuGZ` | | avalanche-fuji | NOT\_PUBLISHED | `https://api.studio.thegraph.com/query/45842/avalanche-fuji-jiffy-scan/version/latest/` | | base-sepolia | [SUBGRAPH\_LINK](https://thegraph.com/explorer/subgraphs/FiEADiC5WBsZ7jSgLdAQSzFR44zAt7jeT51bpaGVDxdi?view=Query\&chain=arbitrum-one) | `https://api.studio.thegraph.com/query/45842/base-sep-jiffy-scan/version/latest` | | fuse | [SUBGRAPH\_LINK](https://thegraph.com/explorer/subgraphs/86D6T6o7YmB5MrSJhMU2Syeqt7r927yecSYcmJrpkTXn?view=Query\&chain=arbitrum-one) | `https://gateway-arbitrum.network.thegraph.com/api/{API_KEY}/subgraphs/id/86D6T6o7YmB5MrSJhMU2Syeqt7r927yecSYcmJrpkTXn` | | base | [SUBGRAPH\_LINK](https://thegraph.com/explorer/subgraphs/9KToKxWC5uRS5ecCFgAxrScDPU2rVMy3hp7abAkt6BED?view=Query\&chain=arbitrum-one) | `https://gateway-arbitrum.network.thegraph.com/api/{API_KEY}/subgraphs/id/9KToKxWC5uRS5ecCFgAxrScDPU2rVMy3hp7abAkt6BED` | | sepolia | [SUBGRAPH\_LINK](https://thegraph.com/explorer/subgraphs/2M32xcbPjStNzTUe8vhtQ29aDyRgb6TfeezA68kHohtM?view=Query\&chain=arbitrum-one) | `https://api.studio.thegraph.com/query/45842/sepolia-jiffy-scan/version/latest` | | arbitrum-sepolia | [SUBGRAPH\_LINK](https://thegraph.com/explorer/subgraphs/8bh2bxiNysQJtqwp1HbEMKPpKDYe5JYGnykGTpmprDWZ?view=Query\&chain=arbitrum-one) | `https://gateway.thegraph.com/api/1afd1a1d48e26c2c6fed3465adb9b876/subgraphs/id/8bh2bxiNysQJtqwp1HbEMKPpKDYe5JYGnykGTpmprDWZ` | | polygon-amoy | [SUBGRAPH\_LINK](https://thegraph.com/explorer/subgraphs/7Nfkhneum5YhB9FKGG6xs3KrmkZHiaDZxLQwiuMxaEYT?view=Query\&chain=arbitrum-one) | `https://api.studio.thegraph.com/query/24129/polygon-amoy-jiffy-scan/version/latest` | | Bsc | [SUBGRAPH\_LINK](https://thegraph.com/explorer/subgraphs/8S8KDUFTAXaV5JEyFesQp3Rwxr5QqbkjyphbjNR7zjBk?view=Query\&chain=arbitrum-one) | `https://gateway-arbitrum.network.thegraph.com/api/{API_KEY}/subgraphs/id/8S8KDUFTAXaV5JEyFesQp3Rwxr5QqbkjyphbjNR7zjBk` | ### Querying the Subgraph Subgraphs allow you to fetch data using GraphQL queries. Below is an example of how to make a query: #### Sample Query ```graphql theme={null} query GetUserOpHash($userOpHash: Bytes) { userOps(where: {userOpHash: $userOpHash}) { verificationGasLimit userOpHash transactionHash } } ``` #### Sample `curl` Request ```bash theme={null} curl -X POST -H "Content-Type: application/json" \ -d '{ "query": "query GetUserOpHash($userOpHash: Bytes) { userOps(where: {userOpHash: $userOpHash}) { userOpHash transactionHash } }", "variables": { "userOpHash": "0x7e4ba0a376476010d3e4ade7b5e5783a74174d3672c620c3148ddcc0f3a58e01" } }' \ https://api.studio.thegraph.com/query/45842/sepolia-jiffy-scan/version/latest ``` Replace the URL with the appropriate subgraph link for the blockchain you are querying. ## Option 2: Use Our TypeScript Library We have created a TypeScript library that implements the top two most-used APIs from Jiffyscan. This library is easy to integrate into your projects. ### Resources * **GitHub Repository:** [Library GitHub](https://github.com/jiffy-labs/graph-wrapper) * **npm Package:** [jiffyscan-graph-wrapper](https://www.npmjs.com/package/jiffyscan-graph-wrapper) ### Installation ```bash theme={null} npm install jiffyscan-graph-wrapper ``` ### Usage Example Below is an example of how to use the library: ```typescript theme={null} import { JiffyscanGraphClient } from "jiffyscan-graph-wrapper"; // Initialize the client with your Graph API key const graphApiKey = "your-graph-api-key"; const client = new JiffyscanGraphClient(graphApiKey); // Fetch network status async function fetchNetworkStatus() { try { const response = await client.getNetworkStatus("base"); console.log("Network Status:", response); } catch (error) { console.error("Error fetching network status:", error); } } // Fetch user operation details async function fetchUserOpDetails() { try { const response = await client.getUserOp("sepolia", "0x7e4ba0a376476010d3e4ade7b5e5783a74174d3672c620c3148ddcc0f3a58e01"); console.log("User Operation Details:", response); } catch (error) { console.error("Error fetching user operation details:", error); } } // Fetch address activity async function fetchAddressActivity() { try { const response = await client.getAddressActivity("sepolia", "0x2bbac9aad155c87343070feedfd03a855c77e695", 1, 0, 0, 0); console.log("Address Activity:", response); } catch (error) { console.error("Error fetching address activity:", error); } } // Call the functions fetchNetworkStatus(); fetchUserOpDetails(); fetchAddressActivity(); ``` Refer to the GitHub repository for complete documentation and advanced usage. *** If you have any questions or require further assistance, please reach out to our support team.
