5.4.4.6 Invoke Smart Contract API Public Key Upload Mode

When the off-BSN system invokes the node gateway, it should follow the API descriptions to add the corresponding parameters. After invoking the node gateway, the node gateway returns the execution result of the smart contract. In the transaction of Public Key Upload mode, the private key of the transaction on the chain is generated and saved by the user. Then the client performs the assembly and signature of the data locally. The signed data is uploaded to the node gateway, which forwards the data to the corresponding blockchain node to initiate the transaction request. Data assembly in this pattern requires information such as the contract ABI, which is compiled when developing the contract, and the contract address, which is available on the application details page. In the SDK of the gateway, the assembly method of the data on the link has been implemented, which can be directly called.
