RattlerAI

Verification

Automated security audit for Solidity and EVM smart contracts, returning a Markdown report with findings by severity, proof of concept snippets and remediation notes. $2 USDC per call on Base or Solana.

Pay from $2.00 in USDC on Base / Solana, settled onchain via the x402 protocol, no signup, no API key needed.

ASSESSMENT

updated 5h ago

Evidence-backed signals, not a single score. Click any chip for the proof. Measured values stay read-only; unknown is honest.

compliance A (11/11)

11 of 11 x402 conformance checks pass. Full checklist below.

category percentile (min): p93 in Verification
endpoints / prices: 1 / 1

stability: 100%

risk clean

No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.

traction $1.53 30d · 2 buyers

volume 30d: $1.53
buyers 30d: 2
settlements 30d: 13
last settlement: 2026-07-21
top buyer share: 63% of 30d volume
trend 7d vs 30d: 0.40x the 30d daily rate
networks: eip155:8453, solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdpKuc147dw2N9d

Attributed pro-quota: this payout address is shared, so volume and buyers are the operator-level figure divided by the services sharing it. A declared convention, not an individually observed measure, and still a conservative undercount.

Top buyer share is a concentration signal, not part of the ranking score.

OVER TIME

All charts share the 24h window selected here. Every series is also served as JSON at /api/v1/services/rattlerai/price, /scores, /volume and /buyers. On-chain volume and distinct buyers are measured over the service's settlement address and are a conservative undercount (only settlements that reach a measured facilitator are counted).

PRICE (captured 402, USD)

SUB-SCORES (uptime + x402 compliance)

VOLUME (on-chain settlement, USD)

Shared payout address (45 other services). These bars are the full shared address (operator-level), so do not sum them across the services that share it. Where a per-service figure is attributed, the assessment block and the ranking, it is the address total divided pro-quota by the 46 services sharing it: a declared convention, not an individually observed measure.

DISTINCT BUYERS

Shared payout address (45 other services). These bars are the full shared address (operator-level), so do not sum them across the services that share it. Where a per-service buyer count is attributed, the assessment block and the ranking, it is divided pro-quota by the 46 services sharing the address and can be fractional: a declared convention, not an individually observed measure.
