Between May 13 and July 28, 2025, a group of independent developers built a run of tools on top of Ethos. They added Ethos scores to token trackers, measured how often people return reviews and mapped reputation networks as graphs. Along the way, Ethos launched a Built on Ethos page to collect their work in one place.
Ethos is a reputation network where people review each other, its data is onchain, and users have an Ethos score. These projects matter because they put that score where people are already making decisions, such as deciding whether to buy a newly launched token, instead of keeping it on a single website.
Ethos scores on a Believe launch tracker
On May 13, 2025, @0x_ultra posted that they had spent an hour coding a live feed for launches on @believeapp, available at believe.xultra.fun. According to @0x_ultra, the feed showed:
- The latest tokens
- Their creators
- Creator stats powered by @getmoni_io
Users could also set specific thresholds for highlights. Ethos called @0x_ultra “the legend himself” for “continuing to add ethos scores everywhere,” and noted that Ethos scores now appeared directly on the tracker.
On May 15, 2025, @0x_ultra described a major infrastructure overhaul of the site. Average latency from launch to fetch dropped from 20 seconds to about 3 seconds, and the tracker began indexing and storing all Believe token and creator information. Ethos pointed out that the Believe/Launchcoin leaderboard could now be sorted by Ethos score, and that @0x_ultra, “unsurprisingly,” had the highest score of any token so far.
An Ethos Responsiveness Score
On May 23, 2025, @1ncrypto released the Ethos Responsiveness Score (ERS) at erscard.xyz. As @1ncrypto described it, the tool tracked mutual reviews on Ethos and measured how responsive a user really was: who left reviews, who ghosted and who was “truly based.” Users entered an EVM address to see how many reviews they still owed.
@1ncrypto called it the first dApp on Ethos and quoted @0x5f_eth describing it as “a native thing just for Ethos that actually solves a problem.” @1ncrypto also noted the project was still under development and that bugs might happen.
Ethos shared the tool by asking people for their responsiveness score, singling out @benwalther256 at 3.1% responsiveness. Shortly after, Ethos noted that the attention looked to have overloaded @1ncrypto’s server a bit.
A graph of your reputation network
On May 26, 2025, @memoJG_ shipped a weekend app called Ethoscope, powered by the Ethos API. According to @memoJG_, users entered an ETH wallet to explore a full graph of who had reviewed them and who was connected to them through trust.
Ethos highlighted that the graph could be filtered by score, showing examples featuring @icobeast and @CrypSaf, and called it “incredible tech.” In the same thread, Ethos told would-be builders that all Ethos data is onchain, but that an API was also available for easier access at developers.ethos.network. Ethos invited them to join its Discord and chat in the builders channel.
The Built on Ethos page
On July 14, 2025, Ethos shipped a new page called Built on Ethos, highlighting developers, integrations and agents built on top of its social infrastructure. Ethos described it as its “first stab at a mini app store.”
At launch, the page featured apps from:
- @buz_eth
- @0x_ultra
- @memoJG_
- @1ncrypto
- @Fookin_No_Wan
The page also included links to documentation, communities and code samples.
Teathos and an open API
On July 25, 2025, Ethos summed up its pitch to developers: “You can just build things. On Ethos.” It listed three points:
- 100% API coverage
- No API keys required
- Reviews can be written directly onchain
The post quoted @serpinxbt, who explained that after @DancingEddie_ tweeted about bribing for Tea reviews on Hinge, they vibe coded an app on Ethos during a stream. Called Teathos and hosted at teathos.deno.dev, it did, in @serpinxbt’s words, “80% of what Tea does.”
Ethos scores on ZoraScan
On July 28, 2025, @0x_ultra added Ethos to another of their dashboards, writing that it “wouldn’t be an ultra dashboard without an @ethos_network integration.” On ZoraScan, at zorascan.xultra.fun, users could check an Ethos score before purchasing new Zora creator coins. According to @0x_ultra, the feature was also available in a Telegram channel.
Ethos’s response was two words: “ethos everywhere.”
