Summary: CryptoSwift is Travel Rule workflow middleware. The useful part is the messaging, scoring, rule-engine, and self-hosted-wallet-verification layer in front of ordinary transfers. Small but real. Not a settlement rail and not some grand new protocol.
What it does:
Sends and receives Travel Rule messages between VASPs through an API and dashboard layer designed to fit alongside existing onchain transaction flows
Returns delivery status, counterparty risk signals, and rule-engine outcomes so customers can automate approvals, holds, reviews, or blocks
Supports both pre-transaction and post-transaction Travel Rule workflows depending on how tightly the customer wants compliance checks coupled to fund movement
Provides self-hosted-wallet verification flows with signature-based, visual-proof, self-declaration, and other evidence options that can be embedded in onboarding, withdrawal, or deposit journeys
Publishes developer-facing operational guidance, workflow docs, and references to an open-source Travel Rule protocol called STRIP
Key claims:
The homepage says CryptoSwift is an end-to-end Travel Rule compliance solution for secure VASP-to-VASP data transmission, counterparty-risk evaluation, and automated compliance decisions
The About page says CryptoSwift was founded in 2022 to help crypto service providers comply with Travel Rule and Transfer of Fund regulations through a simple, secure API
The product FAQ says the platform supports secure message exchange, risk scoring, configurable Rule Engine policies, self-hosted-wallet verification, and easy REST API integration
The workflow docs say CryptoSwift provides the messaging and verification layer while customers retain policy decisions, approvals, customer communication, data collection, and risk thresholds
The self-hosted-wallet-verification page says evidence options can be matched to risk level and customer capability, with signature-based support spanning EVM networks, Bitcoin, Solana, Tron, and more
The product materials explicitly mention support for multiple Travel Rule protocols including STRIP, TRP, TRUST, Sygna Bridge, TRISA, and VerifyVASP
Whitepaper: A white-paper landing page exists, but in this pass it behaved more like a resource hub than a standalone downloadable technical paper. The clearest current sources of truth were the official homepage, About page, product FAQ, developer portal, and workflow documentation; see ../whitepapers/cryptoswift-primary-sources-2026-04-30.md.
