Interact with a Smart Contract

Suggest Edits

In this guide, we will interact with a deployed smart contract using APIs. If you haven't deployed a smart contract, head over to the deploy a smart contract tutorial.

1. Retrieve the Smart Contract's Functions

To fetch the new Contract object, make a GET /contracts/{id} request that includes the contractId object returned from your deployment request. The functions property returned in the successful request contains a list of all of the functions on the contract:

curl --request GET \
     --url 'https://api.circle.com/v1/w3s/contracts/{id}' \
     --header 'accept: application/json' \
     --header 'authorization: Bearer <API_KEY>'

Smart contract functions are defined using the Application Binary Interface (ABI). Some important ABI properties are:

  1. name: The function name. This is used in the abiFunctionSignature to select which function to call when reading from or executing a function on a smart contract.
  2. inputs: The names and types of the arguments to the function. These parameters are passed to the contracts/read or developer/transactions/contractExecution APIs via the abiParameters property.
  3. outputs: The output values when the function returns. Some functions do not return anything.
  4. stateMutability: Defines how the function interacts with the blockchain.
    1. view and pure functions do not change the state of the blockchain, so these are read functions.
    2. nonpayable and payable functions update the state of the blockchaim, so these are execute functions. nonpayable is the default for a function if no stateMutability property exists.

2. Contract Read Function

Once you have selected a read function from the list, you can send an API request to POST /contracts/{id}/read. The example below is making a request to the owner() function to check the current owner of the contract

  • Note: The abiFunctionSignature is derived from the function name and the parenthesized list of parameter types. For instance, the abiFunctionSignature for a function named testFunction that takes an address and an uint256 would be testFunction(address,uint256).
  • Note: Read interactions do not require gas on the blockchain, so you are not required to a specify a wallet.
curl --request POST \
     --url 'https://api.circle.com/v1/w3s/contracts/{id)/read' \
     --header 'accept: application/json' \
     --header 'content-type: application/json' \
     --header 'authorization: Bearer <API_KEY>' \
     --data '

  "abiFunctionSignature": "owner()"

      "0x1bf9ad0cc2ad298c69a2995aa806ee832788218c"
    ]
  }
}

3. Contract Execution Function

Once you have chosen an execute function you can make a request to POST developer/transactions/contractExecution or user/transactions/contractExecution, for developer-controlled and user-controlled wallets, respectively. The example below uses the developer-controlled endpoint to call the safeMint() function to mint an NFT. The function takes in two parameters: the to address and the assigned tokenId for the NFT. The abiFunctionSignature is safeMint(address, uint256).

  • Note: The safeMint function must be called by the owner of the contract. We specified this function modifier when generating the contract earlier.
  • Note: Write functions do require gas on the blockchain, so a walletId must be specified in the request.
curl --request POST \
     --url 'https://api.circle.com/v1/w3s/developer/transactions/contractExecution' \
     --header 'accept: application/json' \
     --header 'content-type: application/json' \
