🗓️ Day 49 – Smart Contract Journey 🚀
🔹Topic: Calldata Decoding & Signature Verification Pitfalls
📚Key Learnings:
✅ Learnt how to decode arbitrary calldata using cast decode
✅ Completed the Elliptic Token challenge
💡Security Mindset:
If a contract pass unhashed data into ECDSA.recover, the signature is no longer bound to a specific message.
This allows an attacker to reuse a valid signature by altering the input data while still recovering the same signer, effectively making the signature authorize unintended actions.
💡Reflection:
Signatures are only as strong as the message they commit to. If the message isn’t explicitly hashed when the contract tries to recover the signer via ECDSA.recover , the signature can be reused in unintended contexts.
🎯Next Step:
Move on to the next Ethernaut level

@timxdesign People don't understand that a tool is infact...just a tool.
Why the banter over which is better?
There must be a competition for who can complain the most
Use it if it works for you, or don't. It doesn't matter.
I'll scroll down now and na wordpress matter I go still read🤦♂️

There are others to explore as well though, like emergency and banani
