Between January and February 2025, Ethos introduced and then relaunched @ethosAgent save, a way for anyone on X to reply to a tweet and have it stored onchain as a review on Ethos. The point was simple: once a tweet was saved, deleting it on X wouldn’t erase the record.
For a reputation network, that matters. Ethos describes its aim as “credibility & reputation onchain,” and the agent let a public statement on X be stored there permanently as a review.
January 19, 2025: a response to deleted tweets
On January 19, 2025, Ethos posted about @RyanAFournier, describing what it saw as “a lack of accountability, continued scams & grifts, and more deleted tweets.” Ethos thanked @RyanAFournier “for setting an example for the class.”
In the same post, Ethos pointed to its answer: replying with “@ethosAgent save” to permanently put tweets on the blockchain “for everyone to see, forever.” Ethos summed up the idea as “credibility & reputation onchain.”
January 30, 2025: the agent was live again
On January 30, 2025, Ethos announced that its agent for storing tweets onchain was live again. To use it, you replied to a tweet with one of two commands:
- “@ethosAgent save”
- “@ethosAgent save target @handle”
Ethos said it would store those tweets as reviews, and shared what it called “a lousy example”: a tweet saved onchain to Ethos by the Ethos agent.
Ethos stressed that anyone could do this. It also warned that the agent might stop responding. If that happened, Ethos said, it had probably been rate limited by Twitter, which wanted $5,000 a month to move up to the next API tier. Ethos said at the time that it expected to have a fix for that within a couple of days.
February 19, 2025: a fuller explanation
By February 19, 2025, people had been using the agent to save tweets, and Ethos laid out three points about it:
- Anyone can do this.
- Saved tweets are stored onchain forever, which preserves them even if they are later deleted.
- The goal is accountability. Saved tweets were meant to add a layer of accountability to Twitter.
Ethos quoted a post from @ethosAgent that repeated the two commands, using “@ethosAgent save target @targetOfTweet” for the second, and explained that they should be posted as a reply to a tweet. According to @ethosAgent, it would reply within 3 minutes with a link to the information saved onchain.
Ethos also published a help article: How do I use the @ethosAgent to save tweets to Ethos?
Still experimental
In the February 19 posts, Ethos noted that the agent was still experimental. It was sometimes rate limited by Twitter and might not always respond.
Ethos added that the whole workflow had been built by an intern, @0x5f_eth, entirely in a workflow tool rather than in code.
Why saving tweets fits a reputation network
Deleting a tweet can make a public statement disappear from X. Saving it to Ethos as a review kept it onchain, attached to the reputation record that Ethos users rely on when deciding whom to trust. And because anyone could trigger a save, the record didn’t depend on the original poster keeping the tweet up.
