`computeAccountAddress` may not work on all EVM chains
GitHub
https://github.com/Cyfrin/2024-07-biconomy/blob/9590f25cd63f7ad2c54feb618036984774f3879d/contracts/factory/K1ValidatorFactory.sol#L111
Summary
The computeAccountAddress function calculates the expected address of a Nexus contract using the factory's deterministic deployment algorithm. It derives the deployment address from the EVM create instruction and returns it.
However, some chains, such as ZkSync Era, have different address derivation methods for create and create2, leading to incorrect address calculations by this function.
Impact
The function may not work correctly on all EVM-compatible chains.
Recommendation
Consider storing the account address directly to ensure compatibility across different EVM chains.
