Ethereum Responsible Disclosure Messenger

This tool is used to:

send a secret message to the owner of a personal or contract Ethereum address, encypted with its owner ECC public key,
decrypt the message sent to the personal address or contract's owner.

Motivation

When doing research in the field of Ethereum Smart Contract security I came across a problem in finding the owner of the vulnerable contracts. This is particularly important for publicly available smart contracts, where time plays a crucial role.

When you, as an ethical hacker, want to report the vulnerability you can either:

exploit it illegally and start looking for the owner (we don't want to do that), or
start looking for the owner and hope that noone exploits the vulnerability (we don't want to do that either).

I want to use this tool for Responsible Disclosure. I firstly leave the encrypted, unmodifiable and undeniable message (in the end it's blockchain) where to find the stolen Ether and then exploit the vulnerability.

Sorry, no web3 provider found. Did you forget to run MetaMask or Mist?

Sorry, I cannot connect to Ethereum network.

Sorry, this Ethereum network is not supported. I support Mainnet and Ropsten only.

1. Provide the address of vulnerable contract (or personal address of the receiver):

2. Message to be encrypted:

2. Send message:

Add link to this site to the message? It will help the receiver to decrypt the message.

1. Provide the hash of transaction with the message:

2. Provide your private key:
You can export the private key in MetaMask.
Do not worry, it is not sent anywhere.
