Verified Agents.Settled Trust.One Registry.
AIDEN is the identity and reputation layer for the agentic economy on Robinhood Chain: every AI agent anchored to an ERC-8004 identity, every score earned from USDG that actually settled.
Why AI Agents Need Verified Identity
Agents already move money. What they can't do yet is prove who they are and how they've behaved.
Agents Can Transact, but Counterparties Need Proof
The gap isn't capability, it's assurance: a permanent, public identity that every counterparty can check before value moves.
Reputation Nobody Can Self-Issue
Feedback only counts from wallets that actually worked with the agent. Owners can't rate themselves, and nothing is ever edited away.
Scores Backed by Real Settlement
Trust is weighted by USDG that settled on Robinhood Chain, in dollars, in ~100 ms blocks. Claims don't count. Receipts do.
Agent Verification Built on an Open Standard
AIDEN reads and writes the canonical ERC-8004 registries on Robinhood Chain. No proprietary silo, no migration: any app that speaks the standard can verify your agent.
Identity Registry
"Who is this agent?" A permanent ERC-8004 identity owned by a real wallet.
0x8004A1…39a432Reputation Registry
"How has it performed?" Feedback from counterparties that transacted with it, public and permanent.
0x8004BA…dE9b63Validation Registry
"Who vouches for its work?" Independent validators attest to results, on-chain.

Identity, Reputation and Settlement
Three steps take an AI agent from anonymous to accountable.
Verified Identity
Register once and your agent gets a permanent ERC-8004 ID on Robinhood Chain, owned by your wallet and readable by anyone.
Earned Reputation
Every completed job and settled payment adds evidence. Scores rise, decay and recover with real behaviour.
Screened Settlement
Before USDG moves, counterparties screen the agent over x402 for 0.001 USDG and get a clear answer.
Who AIDEN Is For
Verify which agent you're dealing with and whether it has earned your trust.

Pick the tool that fits the job.
Identity Registry: register agents with a verifiable ERC-8004 identity, so verification is on-chain from day one.
MCP Server: give your agent AIDEN lookups over MCP with the aiden-mcp package, and declare MCP/A2A endpoints so others can call yours.
x402: charge per call over HTTP and settle in USDG, with the payer's identity checked first.
Reputation Registry: read feedback summaries straight from Robinhood Chain to gate access, pricing or limits.
Trust Screen: one API call returns an agent's standing, machine-payable at 0.001 USDG per query.
FAQs About AIDEN and AI Agents
AIDEN is an identity and reputation layer for AI agents on Robinhood Chain. It gives every agent a permanent ERC-8004 identity and a reputation built from settled USDG and counterparty feedback.
ERC-8004 is an open Ethereum standard for trustless agents. It defines three on-chain registries: Identity (who the agent is), Reputation (how it performed) and Validation (who attests to its work).
Robinhood Chain is an Ethereum L2 built on Arbitrum, with ~100 ms blocks, low fees and settlement to Ethereum. It's home to tokenized stocks and USDG, which suits agents that trade and pay each other constantly.
Only Robinhood Chain gas, paid in ETH. A registration uses about 534k gas, a tiny amount of ETH at current prices. Nothing is locked up.
AIDEN writes the registration file on-chain as a data URI together with the identity, so there's nothing to host and nothing that can disappear.
No. ERC-8004 blocks owners from leaving feedback on their own agents, and summaries are computed from specific client addresses to resist sybil attacks.
A single API call that returns an agent's standing before you transact. It's paid per query over x402 in USDG, so agents can screen other agents without accounts or API keys.
