Introducing ETHYS
The Trust Layer for the Agent Economy

ERC-8004 and the Future of Agent Registries
How blockchain-based agent registration creates permanent, publicly verifiable identities for the autonomous economy

Reputation in a World Without Faces
We evolved to read trustworthiness in eyes, handshakes, and voices. What happens when trust becomes a number? You've done it a thousand times without thinking about it. Someone walks into a room and within milliseconds—before a word is spoken—your brain has already rendered a verdict. Trustworthy or suspicious. Safe or dangerous. Friend or threat. This isn't prejudice (though it can become that). It's evolutionary hardware.

Most AI developers don’t want to become blockchain experts just to prove their agents are trustworthy. Managing wallets, gas fees, and on-chain transactions shouldn’t be a prerequisite for building great AI.
That’s exactly the problem ETHYS solves.
Instead of forcing developers to learn blockchain complexity, we handle everything behind the scenes. You just send simple JSON payloads, and we take care of the rest.
Traditional agent trust systems require developers to:
Create and manage ETH wallets
Handle gas fees and transaction failures
Deploy and interact with smart contracts
Implement cryptographic signatures
Monitor blockchain state and confirmations
For most AI developers, this is onerous - too much complexity for what should be simple trust tracking.
Instead of blockchain complexity, ETHYS gives you simple REST endpoints.
Here’s everything you need to do:

Generate an API key from your Ethys dashboard in 30 seconds. That’s it - no wallet creation, no gas fees, no blockchain setup.
Clicks “Create Agent”
• Fills out form with name, capabilities, metadata
• ETHYS auto-generates agentId and creates custodial wallet for your agent

// Just send your agent's performance data
const telemetry = await fetch('https://api.ethys.io/v1/telemetry', {
method: 'POST',
headers: {
'Authorization': `Bearer ${ETHYS_API_KEY}`,
'Content-Type': 'application/json'
},
body: JSON.stringify({
agentId: "customer-support-bot-v1",
batch: [
{
timestamp: 1703123456,
type: "task",
data: {
operation: "customer_inquiry",
duration: 2300,
outcome: "resolved",
customerSatisfaction: 4.8
}
},
{
timestamp: 1703123460,
type: "success",
data: {
status: 200,
responseTime: 2100
}
}
],
metadata: {
runtime: "node-18.17.0",
host: "support-server-1",
version: "1.0.0"
}
})
});
// Get your agent's trust score instantly
const trustScore = await fetch(`https://api.ethys.io/v1/trust/score?agentId=customer-support-bot-v1`, {
headers: {
'Authorization': `Bearer ${ETHYS_API_KEY}`
}
});
const score = await trustScore.json();
// Returns: { agentId: "...", rs: 85.2, ci: 78.9, updatedAt: "..." }
That’s it. No blockchain complexity, no wallet management, no gas fees.
While you’re sending simple JSON, here’s what we’re doing automatically:
Wallet Management: Auto-create agent wallets with secure key storage
Blockchain Transactions: Submit trust updates to Base blockchain
Gas Fees: Pay all transaction costs from our treasury
ERC-8004 Compliance: Maintain full standard compliance
Cryptographic Signatures: Handle all signature verification
Mathematical Trust Scoring: Calculate RS and CI using proprietary algorithms
With ETHYS, developers can:
Focus on AI: Build better agents instead of learning blockchain
Ship Faster: No blockchain setup delays
🔒 Trust Mathematics: Real trust scoring, not marketing claims
🔗 Stay Compliant: Automatic ERC-8004 compliance
Sign up at ethys.dev
Generate API key in dashboard
Register your agent with one API call
Send performance data as JSON
Read trust scores instantly
No blockchain knowledge required. No wallets to manage. No gas fees to worry about.
Just build great AI agents, send us their performance data, and we’ll handle the trust infrastructure.

Building AI agents? Recording trust onchain is now as easy as calling an API https://blog.ethys.dev/the-api-first-approach-to-ai-agent-trust?referrer=0x4445bDBb45A05417cEA5bBC1c5705497B279AfC1
Is there a way to recover keys if something is lost? Could this become an attack vector down the road?
Great question! The ETHYS agent wallets are just for proving identity and tracking trust scores—your payment systems stay exactly as they are. You can access agent keys through the management area, and we’ve got wallet rotation capabilities coming to keep things secure. It’s all about verifiable trust without disrupting your operations.
