GuestbookETH

The value is that it cannot be undone.

GuestbookETH is an on-chain guestbook for people who want their words—and the value placed behind them—to remain publicly verifiable.

What it is

Most online messages are rented from a platform. They can be edited, moderated, lost with an account, or removed when a company disappears. A GuestbookETH message is written directly to a smart contract on Ethereum. The contract records the wallet that signed it, the time, and the exact message.

Each payment is also emitted in the contract’s public event history. GuestbookETH presents those commitments beside the words, turning the guestbook into a transparent ledger rather than an anonymous comment feed.

How it becomes permanent

  1. 1. Write and review. The message is public. There is no private mode or edit button after confirmation.
  2. 2. Approve the transaction. Your wallet shows the contract payment and a separate network gas fee.
  3. 3. Ethereum confirms it. The smart contract appends the message to its ledger and emits the amount paid.
  4. 4. The record remains. The contract has no function that lets its owner edit or delete an existing entry.

Who it is for

GuestbookETH is for public dedications, milestones, collectors, patrons, communities, and anyone who sees permanence as part of the meaning. The ETH amount is visible because commitment is not incidental here; it is part of the message’s public provenance.

This is not the right medium for secrets, personal information, reversible purchases, or words you may later want removed. Immutability is the product, not a technical footnote.
