How to run index custom data?

To deploy your subgraph on movement mevm devnet.

Step 1. Create Subgraph

Create your subgraph: https://thegraph.com/docs/en/developing/creating-a-subgraph/

Once done, Make sure to set network to devnet

NOTE: Set your network to devnet in your subgraph.yaml file manually. It will not be listed in the graph init command because mevm is not yet supported by thegraph.

Your subgraph.yaml should look something like this:

specVersion: 0.0.4
schema:
  file: ./schema.graphql
dataSources:
  - kind: ethereum
    name: ERC1155
    network: devnet
    source:
      abi: ERC1155
      address: "0x4114e6516413c5ba631002a0cf95e828714f8f18"
      startBlock: 1785835
    mapping:
      kind: ethereum/events
      apiVersion: 0.0.6
      language: wasm/assemblyscript
      entities:
        - NFT
        - NftData
        - NftApprovalForAll
      abis:
        - name: ERC1155
          file: ./abis/ERC1155.json
      eventHandlers:
        - event: TransferBatch(indexed address,indexed address,indexed address,uint256[],uint256[])
          handler: handleTransferBatch1155
        - event: TransferSingle(indexed address,indexed address,indexed address,uint256,uint256)
          handler: handleTransferSingle1155
        - event: URI(string,indexed uint256)
          handler: handleURI1155
        - event: ApprovalForAll(indexed address,indexed address,bool)
          handler: handleApprovalForAll1155
      file: ./src/mapping.ts

info

NOTE: This is just an example no need to copy it as it is.

Step 2. Get AUTH TOKEN from LYNC team

Get your AUTH TOKEN from LYNC Team

Step 3. Set your AUTH TOKEN to prepare for deployment

In your subgraph directory run:

graph auth https://api.mevm-devnet.lync.world/deploy

This will prompt you to enter your deploy key. Pass the AUTH TOKEN in there.

Step 4: Create a new subgraph

graph create --node https://api.mevm-devnet.lync.world/deploy <PROJECT>/<NAME>

warning

Note: Replace the <PROJECT>/<NAME> accordingly. Example lync/nfts

If you have properly setup the correct AUTH TOKEN and subgraph name you should see output like this

If you get any error(s) refer to the Troubleshooting section

Step 5: Deploy you created subgraph:

In the subgraph directory after completing the above steps run:

graph deploy <PROJECT>/<NAME> --node https://api.mevm-devnet.lync.world/deploy --ipfs https://ipfs.lync.world

Note: Replace the <PROJECT>/<NAME> accordingly. Example lync/nfts

If everything goes right you will see output like:

info

Note: Currently we do not have any validations on version label so it can be anything.

Also, you can ignore the HTTP queries endpoint that is shown in the output.

The subgraph will be deployed on:

https://mevm-devnet.lync.world/subgraphs/name/<PROJECT>/<NAME>

Note: Replace the <PROJECT>/<NAME> accordingly. Example lync/nfts

You can use this endpoint to query your subgraph data using graphql.

Troubleshooting

If while deploying the subgraph you face any errors like:

x graph create --node <https://api.mevm-devnet.lync.world/deploy> lync/nfts
 ›   Warning: In next major version, this command will be merged as a subcommand for `graph local`.
✖ HTTP error creating the subgraph: 480

Node.js v20.14.0

Here, take a look at the error code. 480 in the output above.

ERROR CODE	REASON	SOLUTION
401	Request Unauthorized	Make sure the AUTH TOKEN is correct and run the graph auth command again.
470	Naming format not followed properly	The name of the subgraph should be in the format /
480	Name already taken	Reuse of the subgraph name is not allowed. Use a different name.
500	Internal Server error	Contact LYNC Support
