Verified Signatures Tool

‌‌‌‌

Aside from performing transactions and interacting with smart contracts, an EOA (What is an EOA?) is also capable of signing a message. Similarly with the aforementioned activities, signing a message can only be done if you have access to the EOA's private key - which is why signing a message is commonly practiced as a way to verify someone's ownership of an address. It is also how we verify the ownership of a contract address on Etherscan!

Signing a message with an EOA results in a signature hash - a string of characters (that looks like the transaction hash, albeit longer in length) that is unique to a specific signed message (like how a transaction hash is unique to one specific transaction). This is why the message signature hash is crucial in verifying that a message was indeed signed by the EOA that the signer claims to own.

Now that we've cleared the basics, let's jump straight to the highlight - our revamped Verified Signatures Tool.
