Transfers

Bitquery transfers API allows you to retrieve currency or token transfers from cronos Blockchain.

Here's an example query that retrieves the first 10 transfers of USDT tokens between June 17th and June 18th, 2023. The results are sorted based on the timestamp of each transfer in descending order.

query {
  ethereum(network: cronos) {
    transfers(
      currency: { is: "0x01445c31581c354b7338ac35693ab2001b50b9ae" }
      date: { between: ["2023-07-17T00:00:00Z", "2023-07-18T00:00:00Z"] }
      options: { desc: "block.timestamp.iso8601", limit: 10 }
    ) {
      amount
      block {
        timestamp {
          iso8601
        }
      }
      currency {
        address
        name
        symbol
      }
      gasValue
      receiver {
        address
        annotation
      }
      sender {
        address
        annotation
      }
      transaction {
        hash
      }
    }
  }
}
Filtering Transfers

Data retrieved using transfers can be filtered using following arguments:

  • amount: Filter by amount of tokens transferred in a transfer

    Available comparision operators are between, gt, gteq, in, is, lt, lteq, not, notIn.

  • currency: Filter by currency used in a transfer. Currencies supported are native tokens like ETH/ETC, ERC20, ERC721 tokens. For native currencies you can use symbols of them, for contract use address of that contract.

    Available comparision operators are in, is, not, notIn

  • date: Filter by date on which transfer happened. Date should be in ISO8601-encoded datetime string. Ex, June 17th, 2023 will be 2023-07-17T00:00:00Z

    Available comparision operator are after, before, between, in, is, not, notIn, since, tiil.

  • entityId: Filter by ERC-721 entity Id

  • external:

  • height: Filter by height of Block where transaction happened.

    Available comparision operators are between, gt, gteq, in, is, lt, lteq, not, notIn.

  • options: Filter returned data by ordering, limiting and constrainting transfer data.

    Available fields: asc, ascByInteger, desc, descByInteger, limit, limitBy, offset

  • receiver: Filter by receiver of the transfer.

    Available comparision operators are in, is, not, notIn

  • sender: Filter by sender of the transfer.

    Available comparision operators are in, is, not, notIn

  • success: Filter by if transaction is successful or not

  • time: Filter by time when transfer happened. Time should be in ISO8601-encoded datetime string. Ex, June 17th, 2023 will be 2023-07-17T00:00:00Z

    Available comparision operator are after, before, between, in, is, not, notIn, since, tiil.

  • txFrom: Filter by the address responsible for creating the transaction. Available comparision operators are in, is, not, notIn.
