About OnchainWall
OnchainWall is the first public message board for blockchain wallet addresses. Every wallet on Ethereum, HyperEVM, Polygon, Arbitrum, Optimism, and Base has a dedicated page where anyone can leave messages. We support .eth, .hl, and .hype domain names.
For senders: Contact any wallet without knowing their email or social media. Perfect for reaching NFT collectors, recovering funds sent to wrong addresses, making trade offers, contacting Hyperliquid traders, or leaving public thank you notes.
For wallet owners: Claim your page by signing a message with your wallet. Once claimed, you can add a bio, link your X/Twitter profile, and moderate messages on your wall. Works with any EVM-compatible wallet including MetaMask, Rainbow, and Rabby.
Messages can be sent anonymously, with a typed address (unverified), or with cryptographic verification by connecting your wallet and signing. Verified messages show trust signals like wallet age and balance tier.
