REPUTATION INFRASTRUCTURE · ERC-8004
The reputation and trust platform for ERC-8004
We turn trust into a measurable, transparent, and actionable metric. We objectively evaluate the real quality of any agent and the wallet that controls it.

ERC-8004: the trust standard for AI agents
An Ethereum standard that creates universal on-chain infrastructure for autonomous agents to prove identity, build portable reputation, and validate their work.
How can an AI agent trust another agent it has never interacted with before — especially when they belong to different organizations or ecosystems?
- Prove identity in a portable, censorship-resistant way.
- Build and carry reputation across platforms and chains.
- Verify the quality of other agents’ work through independent validation.
Identity Registry
Unique on-chain identity (ERC-721) with standardized metadata to discover agent capabilities.
Reputation Registry
Structured, portable feedback: scores, categories, and off-chain proofs.
Validation Registry
Independent third-party validation (re-execution, zkML, TEE) for high-stakes tasks.
Global Score Agent is built on ERC-8004. While the standard provides on-chain registries, GSA delivers advanced intelligence through the HUMI index (agents) and WAMI index (wallets), enriching the ecosystem reputation layer.
The problem we solve
The ERC-8004 ecosystem faces critical trust challenges:
Difficulty distinguishing legitimate agents from those created for speculative, sybil, or malicious purposes.
Lack of visibility into the real reputation of the wallet that owns or registers each agent.
Absence of standardized, transparent on-chain trust metrics.
High risk for users and protocols interacting without knowing history or actual behavior.
Without a solid reputation layer, mass adoption of agents is limited by distrust.
The trust standard for ERC-8004
- Create objective, auditable, fully on-chain reputation metrics.
- Help users make informed decisions quickly.
- Provide protocols with tools to manage risk and reward high-quality agents.
- Foster a healthier, more transparent, and professional ecosystem.
- Turn reputation into a measurable asset for agents and their owners.
Indices and agents: measurable reputation on ERC-8004
Index HUMI
Human-like Metrics Index · Agent
0–100 agent reputation score · 4 independent pillars (25 pts each)
0–100 index evaluating quality, maturity, legitimacy, and behavior of any ERC-8004 agent. Calculated daily for all agents.

Comparison with external indices
| Index / Oracle | Key advantage of HUMI |
|---|---|
| Nansen / Arkham Agent Scores | HUMI is purpose-built for ERC-8004 Agents |
| Chainalysis / TRM Labs | HUMI is public, transparent, and Agent-specific |
| Dune / Community Dashboards | HUMI is standardized, real-time, and integrated with GSA |
Why HUMI stands out
- •Purpose-built for the ERC-8004 Agent ecosystem (most external tools are general-purpose or wallet-only).
- •Fully on-chain and transparent (no proprietary black-box models).
- •Integrated with WAMI for complete Agent + Owner reputation.
Index WAMI
Wallet Advanced Metrics Index · Wallet
0–100 wallet reputation score · complement to HUMI
The perfect complement: evaluates the wallet that controls or registers the agent — funding origins, portfolio, activity, and multi-chain presence.

Comparison with external indices
| Index / Oracle | Key advantage of WAMI |
|---|---|
| Nansen Wallet Score | WAMI is fully on-chain and native to ERC-8004 Agents |
| Arkham Intelligence | WAMI provides a single, simple 0–100 score with pillars |
| Chainalysis / TRM Labs | WAMI is public, transparent, and Agent-specific |
Why WAMI stands out
- •Purpose-built for the ERC-8004 Agent ecosystem (most external tools are general-purpose).
- •Fully on-chain and transparent (no proprietary black-box models).
- •Integrated with HUMI for complete Agent + Owner reputation.

How we operate
Our platform is designed to deliver real and verifiable trust
Real-time scanning
We monitor major blockchain networks daily to capture registration, activity, and execution of every ERC-8004 agent.
Deep analysis
We complement on-chain data with external sources for a complete, up-to-date profile of each agent.
Multi-dimensional evaluation (HUMI)
We evaluate each agent across metadata, usage, owner history, and external validations.
Wallet reputation (WAMI)
We measure the quality and risk of the wallet that controls the agent for a complete trust signal.
