How Attestyx compares
The integrity layer for any payment.
The closest comparisons fall into five categories.
Per-transaction risk and KYC/KYB orchestration
Sardine, Alloy, Sift, Unit21 - the closest functional comparisons.
| Dimension | Sardine / Alloy / Sift / Unit21 | Attestyx |
|---|---|---|
| Per-transaction risk score | Yes | Yes (Tier 1) |
| KYB orchestration | Yes | Yes (Tier 2) |
| Cross-customer registry | Limited or absent | Yes (cross-network bad-actor registry) |
| Court-portable evidence | No | Yes (Tier 2 CREB bundle, FRE 902(14)) |
| On-chain forensics built in | No (or limited) | Yes |
| Forensic engagement (Tier 3) | No (separate vendors) | Yes |
| No-custody architecture | Implicit | Productized |
| Public pricing | Mostly opaque | Fully public (5 bps + $0.25 floor) |
| Free Forever tier | No | Yes |
| Network compounds | Modestly | Yes, by design |
We subsume the per-transaction-scoring + KYB-orchestration role and add three layers above it (cross-network registry, court-portable evidence, forensic Tier 3).
Sanctions-only screening
ComplyAdvantage, Refinitiv World-Check.
| Dimension | ComplyAdvantage / Refinitiv | Attestyx |
|---|---|---|
| Sanctions screening | Yes (their entire product) | Yes (8 of 39 Tier 1 checks) |
| PEP screening | Yes | Yes (2 of 39) |
| Per-transaction integrity verdict | No | Yes |
| Per-transaction signed receipt | No | Yes |
| CREB attestation | No | Yes (Tier 2) |
On-chain forensics
Chainalysis, TRM, Elliptic.
| Dimension | Chainalysis / TRM / Elliptic | Attestyx |
|---|---|---|
| On-chain forensics depth | Excellent (their entire product) | Yes (Tier 3) |
| Per-transaction wallet integrity check | Yes (basic) | Yes (Tier 1, in milliseconds) |
| Fiat-rail coverage | None | Full |
| Per-transaction signed receipt | No | Yes |
| CREB attestation | No | Yes |
Stablecoin payment rails
ProofPay.net and adjacent. Structurally different - they are a payment rail, we are not.
| Dimension | ProofPay.net (stablecoin rail) | Attestyx |
|---|---|---|
| Core product | A payment rail | A verification API that runs on top of any rail |
| Custody | Funds transit through their infrastructure | Never holds, routes, or transmits funds |
| Rail coverage | Stablecoin only, corridor-limited | Any rail |
| Buyer | Enterprise AP teams | Banks, fintechs, acquirers, networks, marketplaces, foundations, payroll, insurance, treasury |
| Pricing | Spread on FX and stablecoin conversion | Flat 5 bps + $0.25 minimum on Tier 1, flat fees on Tier 2 / 3 |
| Compliance posture | Asserted in marketing | Productized: 39 deterministic checks, signed receipt, FRE 902(14) admissible |
| Evidence output | Blockchain transaction hash (generic) | CREB bundle |
| Network effect | None apparent | Cross-network registry compounds with every customer |
| Regulatory exposure | High (likely money transmitter) | Low (no custody, no MTL trigger) |
ProofPay.net is a cheaper rail. Attestyx is the integrity layer that any rail can plug into. Customers can use both. Use ProofPay.net (or Wise, or your own banking partner) for the rail. Use us for the integrity verdict before sending. The two flows do not overlap.
Equivalency-determination law firms
| Dimension | Equivalency-determination law firms | Attestyx |
|---|---|---|
| One-time legal opinion | Yes ($5K to $15K per opinion) | Yes (Tier 2 verification, flat fee, reusable) |
| Ongoing monitoring | No | Yes (Tier 2 monitoring) |
| Reuse across foundations | No | Yes |
| Court-portable evidence | Bespoke, expensive | Yes (CREB bundle, automated) |
DIY internal stacks
| Dimension | DIY | Attestyx |
|---|---|---|
| Time to first value | 18 to 36 months | 24 hours |
| Engineering cost | $5M+ | $0 to integrate |
| Network effect | Single-platform intelligence | Cross-network |
| Coverage of 148 checks | Whatever you build | All 148, locked, audited |
| Court-portable evidence | Build it yourself | Productized in CREB |
What we are explicitly not
- Not a charity rating service
- Not a giving platform
- Not a money transmitter
- Not a fiduciary
- Not a card network
- Not a payment rail
- Not a contingency-fee recovery firm
- Not a replacement for your existing fraud-modeling team
When you would use us alongside something else
- Tier 1 + your existing fraud model:you keep your model for behavioral signal, we give you the deterministic signal and the evidence layer.
- Tier 2 + a law firm:we handle verification at scale, the firm handles the bespoke legal opinion when one is genuinely needed.
- + Chainalysis:us for the per-transaction integrity layer, Chainalysis for deep crypto-forensics work that exceeds Tier 3 scope.
- + your existing payment rail (Stripe, Adyen, ProofPay.net, your bank, Visa Direct, Mastercard Send): us for the integrity verdict; your existing rail for the money movement.
