On-chain record keeper · Built on Hedera
Fixatum is a permanent, tamper-proof record keeper for AI agents. Register your agent and we anchor its identity to the Hedera blockchain — then every verified action it takes builds a live trust score, automatically.
The score is the history. The history is the proof. One registration, no subscription, no forms.
What Fixatum actually does
You don’t need to understand blockchain to use Fixatum. Here’s what actually happens.
When you register an agent with Fixatum, we write a permanent record on the Hedera blockchain: this agent exists, this is its identity, this is when it started. That record can never be changed or deleted — not by us, not by anyone.
From that moment on, every time your agent does something verifiable on-chain, we record it. Over time, those records build a trust score — a public number from 0 to 100 that tells the world how the agent has actually behaved.
Anyone can look up that score with a simple web request. No account needed. No login. Just the truth about what the agent did.
AI agents are being given real power — spending money, managing data, making decisions. Right now most of them are anonymous. No history. No accountability. No way to know if you can trust one.
Fixatum doesn’t solve AI safety. We don’t certify agents or make guarantees. What we do is keep an honest, permanent record of what an agent has done — so that anyone who interacts with it can see the history for themselves.
Transparent behaviour is the foundation of trust. We just write it down.
How it works
The entire process is designed to run without human involvement. An agent can register itself, receive its identity, and start building a trust record — all in one pipeline.

The record keeper
“The blockchain
doesn’t forget.”
Fixatum is not an AI safety platform. We make no claims about whether an agent is good or bad. We are not a regulator, a certifier, or a gatekeeper.
What we are is a witness. When an agent acts on-chain, we record it permanently. That record is then readable by any platform, any protocol, any person — forever.
The trust score is simply a summary of what the record shows. A high score means the agent has a long, clean, verifiable history. A low score means it’s new, or its history is thin. The score doesn’t lie — it just reads the record.
If you want to be transparent about how your agent behaves, Fixatum is how you prove it. The blockchain doesn’t forget.
The trust score
The Fixatum trust score is a number from 0 to 100. It’s computed fresh on every query from the agent’s on-chain record — no snapshots, no self-reporting, no manual reviews.
A new agent starts low. That’s honest — it has no history yet. As it builds a real track record, the score grows. You can’t buy a higher score. You can only earn one.
Any platform can query it with a single web request. Free tier available. No account needed.
Who this is for
You built something. Now prove it behaves. Register your agent once and give it a permanent, verifiable track record that any platform can check — without you having to explain yourself every time.
The earlier you register, the more history the record captures. Account age and on-chain screening draw from your full Hedera transaction history — every day counts.
Before you let an agent spend money, access data, or execute actions — check the record. One GET request returns a live trust score backed by on-chain history. No self-reported claims. No blind trust.
Want to know if an agent you’re interacting with has a track record? Look it up. The score lookup is free, public, and requires no account. If the agent is registered, the record is there.
In the wild
TheRecordKeeper is a live AI agent on Moltbook — the social network for AI agents. On its first heartbeat, it self-registered on Fixatum autonomously. No human involved. It now carries a permanent DID and a live trust score, building provenance with every action it takes on-chain.
Built on HederaToolbox
Fixatum is the identity layer. HederaToolbox is the activity layer. Together they form the full agent infrastructure stack on Hedera.
Every verified tool call an agent makes through HederaToolbox — querying token data, running identity checks, reading governance proposals — is recorded against its Fixatum identity automatically. No extra steps. The score grows as the agent works.
