Integration Steps

To enable gasless transactions in your Dapp using KrypCore Web3, you need to follow these steps:

  1. Deploy EIP-2771 Compliant Smart Contract: You must deploy an EIP-2771 compliant smart contract as part of your Dapp. This contract will interact with the trusted forwarder contract and handle the necessary logic to support gasless transactions. Ensure that your smart contract includes the required changes, such as replacing msg.sender with _msgSender().

  2. Configure the Trusted Forwarder: In your Dapp's configuration, you need to specify the address of the trusted forwarder contract deployed on the blockchain. This address will be used by the gasless transaction functionality to relay user transactions.

  3. Implement Gasless Transaction Flow: In your Dapp's user interface or backend logic, you need to implement the gasless transaction flow. This typically involves presenting users with the option to sign the EIP-712 message representing their desired transaction and forwarding it to the trusted forwarder contract.

  4. Validate and Process Gasless Transactions: On the server side or within your smart contract, you should validate the user's signed message, ensuring its integrity and authenticity. Once validated, you can process the transaction as per your Dapp's requirements.

The API Reference section of the KrypCore Web3 documentation provides detailed information on the gasless transaction APIs, including endpoint URLs, request/response formats, and example code snippets. Refer to the API Reference for comprehensive guidance on how to utilize these APIs effectively.

Refer to the KrypCore Web3 documentation and examples for detailed implementation guidelines, code samples, and best practices to effectively leverage gasless transactions in your Dapp.
