Contract Call

Contract call refers to the operation of executing a smart contract on the blockchain. Through a contract call, users can interact with the target smart contract and execute the functions or methods defined within the contract.

Command​

You can contract call using the following command:

  npm run contract:call -- --skfile {privateKey-path} \
                         --contract {smart-contract-address}  \
                         --abi ./build/contract/xxx.abi   \
                         --method {method-name}  \
                         --args [..] \
                         --gas 200000

options：

  • --abi : contract abi path.
  • --contract: smart contract address.
  • --method: method name.
  • --skfile : privateKey path for sender. (optional,default value ./privateKey.txt).
  • --args : If your contract's constructor requires input parameters, use --args '[1, "a"]' (optional).
  • --gas : like 200000,(optional,default value 7000000).

Example​

## usage 1: call a contract 'xxxx.sol' with hello() method, using default private key './privateKey.txt'
npm run contract:call --  --contract 0xa1ab92B67C4Bd8bb0fa1C08F29A90b375c260185 \
                          --abi ./build/contract/xxxx.abi \
                          --method hello
                        
## usage 3: call a contract 'xxxx.sol' with 'add(int32 num)' method, using private key './privateKey2.txt'.
npm run contract:call --  --contract 0xa1ab92B67C4Bd8bb0fa1C08F29A90b375c260185 \
                          --abi ./build/contract/xxxx.abi \
                          --method add \
                          --args 100
                    
## usage 3: call a contract 'xxxx.sol' with 'unbind(address aspectId, address account)' method, using private key './privateKey2.txt'.
npm run contract:call --  --contract 0xa1ab92B67C4Bd8bb0fa1C08F29A90b375c260185 \
                          --abi ./build/contract/xxxx.abi \
                          --method unbind \
                          --args 0xCE3ccD4a308f25B4c1B36cC883A9bEd76Bc24627 0xA90927a72F1A6c8EFAfa0cc1b432f75eCc2086d8 \
                          --skfile ./privateKey2.txt

Customize​

The logic for the create-account command is written in the scripts/contract-call.cjs file, primarily relying on the implementation provided by the @artela/web3 API.
If needed, you can modify the logic within this file to achieve your specific functionalities.

Furthermore，you can modify the project.config.json in the project root folder to set the network configurations..
