Ethereum contractual installation problems with Binance Smart Chain (BSC)
As a developer, he works with Ethereum-based intelligent contracts and is likely to know the installation of different networks. At the same time, the Binance on an intelligent chain (BSC) is not uncommon with the problems that arise when attempting to try its contract.
In this article, we are immersed in the reasons behind installation issues and give guidance to solve them.
Understand the error
The error message indicates that there is a problem with the found “header” found. This suggests that the contract code or ABI (application binary interface) results in incorrect or incomplete, and results in a missing or invalid header file.
Troubleshooting steps
Let’s go through a few steps to troubleshoot and solve these questions:
1. Check the contract code and ABI
Make sure your contract code and ABI are correct and up to date.
- Double check the source code of the contract (such as truffles, remix or Etherscan) for any syntax error.
- Check the ABI of the contract against Ethereum SDKs provided by BSC (such as BSC-APIS/ABI
) or other compatible sources.
2. Refresh the truffle configuration
When installing in different networks, you may need to update your truffle configuration files to ensure compatibility with the new network. Specifically:
- To BSC:
* Update “Network” in the configuration file of the truffle project (buffle.js’) to point to BSC.
`Javascript
// truffle.js
Module.Exports = {{
Networks: {
BSc: {
HOST: '127.0.0.1',
Port: 8545,
Network_id: 56,
},
},
};
3. Check network-specific configurations
Make sure that the truffle configuration file has appropriate BSC-specific settings, for example:
Gasprice
: Set to the appropriate value of BSC’s gas price.
Maxgas
: set according to the height and gas limit of the BSC block.
4. Ropsten and BSC Testnet Specifications
If you have already installed the contract on a Testnet, such as Ropsten or other BSC, make sure that:
- The truffle configuration file is updated to the testnet.
- Use the up -to -date version of the truffle.
5. Review BSC MainNet settings
Finally, read the Binance Smart Chain Mainnet settings to make sure they meet the truffle configuration file:
- Update
Network_id
in the truffle configuration file if necessary.
Conclusion
Installing contracts can be a complex process on different networks. If you follow these troubleshooting steps and update your truffle configuration files as needed, you should be able to solve the problems and successfully install the contract on the main network of BSC.
If you continue to have problems or have further questions, consider contacting the Ethereum community or helping online forums or documentation sources.
