PassimPay is a cryptocurrency payment processor and Web3-enabled payments service founded in December 2022, that enables businesses to accept, manage, and settle crypto payments through application programming interfaces (APIs), plugins, payment links, and wallet-connected checkouts.

Operated from Warsaw, Poland, the service emphasizes automatic conversion options, multi-asset support, mass payout tools, and merchant account controls aimed at business payment workflows. ^{[1] [2]}​

• or QR-based payment requests, alongside connectivity with popular Web3 wallets. Its product positioning focuses on fast integration, configurable conversion to stablecoins, report and account management features, and optional white-label and brand customization. ^{[1] [2]}​

Services and features

PassimPay’s service offering centers on crypto payment acceptance and merchant tools designed for operational control. Core features described on the official site include:

• API and CMS plugins — payment integration for WordPress, Shopify, and other platforms.
• Multisender — a tool for executing multiple simultaneous payouts in a single transaction, used for payroll, affiliate rewards, and mass distributions.
• Auto-Conversion — automatic conversion of incoming assets into stablecoins such as USDT or USDC upon receipt, intended to reduce exposure to market volatility.
• SEPA Integration — conversion of cryptocurrency earnings into EUR with direct transfers to bank accounts via the SEPA network.
• Invoicing — generation of digital invoices and QR codes for crypto payment processing.
• KYC/AML compliance — identity verification and anti-money laundering procedures in accordance with industry standards, alongside transaction analytics tools. ^{[2] [1]}

Security, compliance, and risk management

PassimPay states that it employs Know Your Customer (KYC) and Know Your Business (KYB) procedures and asserts compliance with anti-money laundering (AML) requirements, supported by an in-house compliance function. The company describes transaction risk assessment processes intended to flag anomalous payment activity. It also claims annual cybersecurity audits conducted by third-party firms, naming 10Guards and Hacken; however, the consulted pages do not provide linked audit reports, dates, or scopes. The site includes risk disclaimers about the storage and transfer of digital assets and indicates that the irreversibility of blockchain transactions eliminates chargebacks. ^{[1] [2]}​

A prominent company-stated assurance on the site characterizes client funds as “at users’ disposal and [can] be returned on first demand.” This is presented as the company’s own guarantee rather than a third-party attestation. The site explicitly disclaims responsibility for losses stemming from unauthorized account access and warns of the inherent financial risks of cryptocurrencies. Readers should note that, for the materials consulted, there were no posted independent certifications (e.g., SOC/ISO) or detailed audit publications available to corroborate the audit claims. ^[1]​

Integration and developer tooling

The service provides a server-side API for custom integrations and lists plugins for common content management and e-commerce platforms. For checkout flexibility, it offers payment links and invoices, QR code generation, static deposit addresses for repeated payers, and Web3 wallet-based payments that connect with MetaMask, Trust Wallet, and Coinbase Wallet.

The About page references white-label and brand customization, a Telegram bot delivering statistics, and an on-site AI assistant for support and guidance. PassimPay further mentions a mobile application for operational access, though low-level technical documentation (e.g., custody model, supported chain list, and protocol specifics) is not detailed on the consulted pages. ^{[1] [2]}​
