op-attestations-subgraph

Subgraph for Optimism's Attestation Station. Deployed with the Graph Protocol's hosted service here.

This subgraph just tracks AttestationCreated events from the AttestationStation. To enable pagination through all attestations, by address, key, or both, we also track attestation counts and indicies.

To query for all attestations, in order

query {
    attestations(
      orderBy: index,
      orderDirection: desc,
      first: numRows,
      where: {
        index_lte: start,
      },
    ) {
        id
        about
        creator
        key
    }
}

To query by key:

query {
    attestations(
      orderBy: index,
      orderDirection: desc,
      first: numRows,
      where: {
        and: [
          { indexForKey_lte: start },
          { key: key },
        ],
      },
    ) {
        id
        about
        creator
        key
    }
}

To query by address:

query {
    attestations(
      orderBy: index,
      orderDirection: desc,
      first: numRow>,
      where: {
        or: [
          { about: address, indexForAbout_lte: start },
          { creator: address, indexForCreator_lte: start },
        ],
    ) {
        id
        about
        creator
        key
    }
}

Or both

query {
    attestations(
      orderBy: index,
      orderDirection: desc,
      first: numRow>,
      where: {
        or: [
          { about: address, indexForAbout_lte: start, key: key },
          { creator: address, indexForCreator_lte: start, key: key },
        ],
    ) {
        id
        about
        creator
        key
    }
}
