In this section we'll have a look at some examples using the Optimism Transfers API.

This Optimism API is part of our Early Access Program (EAP), which is intended for evaluation purposes.

This program allows you to test the data and its integration into your applications before full-scale implementation. Read more here

subscription {
  EVM(network: optimism) {

Sender is a particular address

This websocket retrieves transfers where the sender is a particular address 0xEbe80f029b1c02862B9E8a70a7e5317C06F62Cae. For this subscription query we use where keyword and in that we specify {Transfer: {Sender: {is: "0xEbe80f029b1c02862B9E8a70a7e5317C06F62Cae"}}} to get the desired data. You can find the query here

subscription {
  EVM(network: optimism) {
    Transfers(
      where: {Transfer: {Sender: {is: "0xEbe80f029b1c02862B9E8a70a7e5317C06F62Cae"}}}
