PlatON compatibility

Investigate compatibility with ERC20 deployment in PlatON1.5.0 compiler

  1. Compatibility between Smart Contract Language and Compilers:
    ERC20 smart contracts are typically written in Solidity language. Solidity is a contract programming language for Ethereum virtual machines. Generally speaking, The Solidity code needs to run on a blockchain platform that supports EVM (Ethereum Virtual Machine). Different blockchain platforms may have their own compilers or interpreters to handle Solidity code, such as the Ethereum main network Binance Smart Chain, Polkadot, etc. Although they all follow the EVM standard, there may be differences in the implementation and support of certain specific features, which may affect the compatibility of the contract.

  2. Version differences between different compilers:
    Similar to traditional programming languages, Solidity compilers also come in different versions, each of which may have varying levels of support for language features. For example, some compilers may not support the latest version of the Solidity feature, which requires developers to consider the version compatibility of the target compiler when writing code.

  3. Differences in cross platform compilers:
    When using third-party compilers or libraries, such as the OpenZeppelin library, there may be compatibility issues between different platforms. Some third-party libraries may have been optimized for specific platforms, resulting in unexpected behavior when running on other platforms.

  4. Compatibility between ABI (Application Binary Interface) and binary code:
    The binary code (bytecode) and its ABI generated by smart contracts after compilation may vary on different compilers and chains. This may affect the interaction of contracts, especially when deploying contracts in different blockchain environments or interacting with contracts.

  5. Differences in network environment:
    The environment and transaction cost mechanism of different blockchain networks may also affect the deployment and operation of smart contracts. For example, deploying and running contracts in certain fast and low-cost network environments may be more cost-effective.

  6. Security and optimization issues:
    When the compiler converts Solidity code to EVM bytecode, it may optimize the code to improve efficiency or ensure security. Different compilers or compiler versions may adopt different optimization strategies, which may affect the behavior and compatibility of the contract.
