On-Chain Data

The ISME SDK wraps many query functions for on-chain data, currently including:

  • tokens - tokens held by DID users
  • txs - transaction records of DID users
  • poaps - POAPS records for DID users
  • ens - ENS records of DID users
  • timeline - On-chain transaction data timeline for DID users, currently supports txs and poaps
  • ensTextRecords - query ENS records by address
  • opensea - OpenSea assets held by DID users

Steps​

To use the data query function, you only need to create a queryer instance. For more details, please refer to the API documentation.

import { ISMEQueryer } from '@ismelabs/client'
import { useISME } from '@ismelabs/did-manager'

export default function VerifierDemo() {
  const { client, identifier } = useISME()

  const queryer = useMemo(() => {
    return new ISMEQueryer(client, 'https://t0.onebitdev.com/nft3-queryer/')
  }, [client])

  const query = async () => {
    const data = await queryer.query({
      tokens: {
        did: identifier
      },
      txs: {
        did: identifier
      }
    })
    console.log(data)
  }
}
