"summary": "This PR involves a minor update to the dependencies list in pyproject.toml. The changes from specific versions (4.3.1 and 6.3.0) to more general versions (eth_typing>=4.0.0 and web3>=6.3.0) are likely to be non-breaking and do not introduce significant risks. The update is focused on flexibility and compatibility, which aligns with the 'BLUE' category, indicating a low complexity PR.",

We want to add an upper bound version to enforce semver to avoid randomly breaking our installation.
