Verified Signatures Tool

Note: Moonriver (MOVR) on Kusama is a companion network to Moonbeam and provides a permanently incentivized canary network. New code ships to Moonriver first, where it can be tested and verified under real economic conditions. Once proven, the same code ships to Moonbeam on Polkadot.

Polygon PoS (polygonscan.com) is an EVM-compatible environment optimized for high throughput and low transaction fees while Polygon zkEVM (zkevm.polygonscan.com) is an EVM-equivalent ZK rollup designed for security.

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 Blastscan!

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.
