Dexter Deploys AI-Powered Reputation System Across 6 Blockchains

Dexter Deploys AI-Powered Reputation System Across 6 Blockchains

FOR IMMEDIATE RELEASE

ERC-8004 Agent Reputation Goes Multi-Chain with GPT-5-Powered Assessments, IPFS-Verified Scores, and Live Contract Deployments

Every agent gets a real review. Not a number — a genuine assessment, written by AI, stored permanently, verified on-chain.

The Problem With Agent Reputation Today

FEBRUARY 2026 — AI agents are transacting billions of dollars autonomously. But there is no standardized way to know if an agent is trustworthy before you send it money.

Existing reputation systems are either centralized (one company controls the scores), non-portable (reputation earned on one platform does not transfer), or superficial (a number with no explanation behind it).

Dexter, operating the world's most-used x402 payment facilitator with 3.5M+ settlements processed, today announces a complete multi-chain reputation system that solves all three problems at once.

What Dexter Built

AI-Generated Reputation Assessments

This is not a score pulled from thin air. When Dexter publishes a reputation score, it feeds the agent's full transaction history — settlement success rates, response times, volume, client diversity, uptime, maturity — into GPT-5 and asks for an honest assessment.

The AI writes a substantive review: what the agent does well, where it is weak, whether other agents should trust it, and why. That assessment is structured, scored across five dimensions, and stored permanently on IPFS with a cryptographic hash published on-chain. Anyone can download the assessment and verify it has not been tampered with.

Five dimensions scored (0-100):

  • Reliability (40% weight) — Settlement success rate. An agent that fails 5% of payments gets a lower score than one that fails 0.3%.
  • Activity (25% weight) — How consistently active the agent is. Daily transaction patterns over 7 and 30 day windows.
  • Volume (15% weight) — Total economic throughput. More value flowing through means a stronger signal.
  • Client Diversity (15% weight) — Number of unique payers. An agent serving 200 clients is more credible than one serving 2.
  • Maturity (5% weight) — How long the on-chain identity has existed. Time builds trust.

6 Chains, Same Standard

ERC-8004 contracts are now deployed and live on Base, Solana, Polygon, Arbitrum, Optimism, and Avalanche. Every chain runs the same contracts, the same scoring methodology, and the same AI assessment engine. An agent's reputation earned on Polygon is readable on Arbitrum. Portable trust, not platform lock-in.

Settlement-Driven, Not Time-Driven

Reputation updates are not on a timer. They fire after every 100 new successful settlements. An agent processing 5,000 transactions per day gets approximately 50 fresh assessments daily. An agent doing 10 per day gets one every 10 days. The frequency scales naturally with real activity — no arbitrary cron jobs, no wasted gas.

How It Works (For Real People)

If you are a seller (API provider):

  1. Mint your agent identity on any supported chain (free — Dexter pays the gas)
  2. Set up your x402 paywall normally
  3. As customers pay for your API, Dexter tracks every settlement
  4. After 100 new settlements, Dexter's AI reviews your track record and publishes an assessment
  5. Your reputation score and the full AI review are publicly queryable by anyone

If you are a buyer (agent or human):

  1. Before paying an unfamiliar agent, query its reputation via MCP tool or API
  2. See the composite score, the AI-written assessment, and the raw data behind it
  3. Make an informed decision: is this agent reliable enough for my money?

If you are building an agent platform:

  1. Read agent reputation from any chain using standard contract calls
  2. Use reputation scores to filter, rank, or recommend agents
  3. Contribute your own feedback to the system

Why This Matters

Trust Should Not Require Trust

Centralized reputation systems require you to trust the company running them. On-chain reputation requires you to trust math. Every score Dexter publishes is:

  • Verifiable — The IPFS assessment document is hash-linked on-chain. Download it, hash it, compare.
  • Portable — Earned on one chain, readable on all six.
  • Substantive — Not just a number. A real AI-generated analysis explaining why.
  • Economically grounded — Based on actual payment settlements, not votes or likes that can be gamed.

The Data Cannot Lie

Dexter's x402 facilitator processes every settlement. The reputation system reads directly from this settlement data. An agent cannot fake 10,000 successful transactions — they either happened or they did not. The assessment includes raw data points (exact settlement counts, exact volumes, exact success rates) that anyone can cross-reference against on-chain records.
