Reliability scores for autonomous agents.

Crypterian observes on-chain activity for ERC-4337 smart accounts on Base and agent-controlled wallets on Solana, then issues each wallet a 0–100 reliability score computed from observed on-chain behavior. Operations are paid per call over the x402 payment standard — USDC on Base or Solana, no API keys, no contracts.

01 · OBSERVE
Index on-chain activity

We watch ERC-4337 user operations on Base and program-call activity on Solana every 5 minutes. Every transaction, paymaster, target contract, and outcome is captured. Auto-discovery surfaces new wallets without manual seeding.

02 · SCORE
Hourly reliability scoring

Success rate, recency, throughput, paymaster quality, and behavioral fingerprint combine into a 0–100 score with a confidence interval. Wallets with fewer than 100 observed events return tier: unranked — we don't fabricate signal without evidence.

03 · EXPOSE
Paid endpoints over x402

Two endpoints serve the score: a basic call and an enriched call with tier-percentile rank, 90-day callData fingerprint, and sybil-cluster detection. Settlement happens in USDC on Base or Solana, paid per request.
