# 与以太坊EVM的差异
## 未实现的Opcodes
- CREATE/CREATE2
长安链上创建合约需要权限,不是谁都可以创建的,比较稀少。且实现复杂度比较高。故未实现。
- CALLCODE
callcode指令从solidity 5.0开始被[禁用](
https://docs.soliditylang.org/en/v0.8.17/050-breaking-changes.html)。这个指令(现改用delegatecall),仍然可以通过内联汇编使用它。我们希望在我们的layer2上也禁用这个指令,故未实现。
- SELFDESTRUCT
该指令自solidity 0.8.18已经标记为[deprecated](https://soliditylang.org/blog/2023/02/01/solidity-0.8.18-release-announcement/),我们希望在我们的layer2上也禁用这个指令,故未实现。
