Transaction Relay (TX)

Read Contract and View Functions

For your convenience, we've added a simple way to invoke view functions on already deployed contracts. These functions will fail if they modify the blockchain in any way.

DO NOT use this API to:

  • Modify state variables.
  • Emit events.
  • Deploy contracts.
  • Send ether.
  • Call any function which is not marked view or pure.
