Overview​

Vision & Mission​

reply.cash is the first universal stablecoin sender: enabling anyone to send and receive stablecoins directly to social or messaging accounts—no wallet required. All you need is a handle.

Our mission: Make stablecoin payments as easy and universal as messaging, unlocking financial access and utility for billions.

The Problem​

Stablecoins are the fastest-growing asset for payments and savings, but onboarding is broken.

The Fragmented Stablecoin Landscape​

The stablecoin ecosystem is increasingly fragmented across chains and issuers. In 2025, with the GENIUS Act passage, major financial players have entered the space. PayPal's PyUSD, Visa's stablecoin initiatives, and Cloudflare's NetCoin are joining established players like USDC and USDT, creating a complex landscape for users to navigate.

According to McKinsey, stablecoin transaction volume has grown at 65% annually since 2020.

Key Friction Points​

Everyday Payment Friction​

P2P payments through traditional banks still take 2-3 business days to clear, while stablecoins settle in minutes. However, sending stablecoins requires technical knowledge most users don't have.

Cross-Chain Complexities​

Even crypto-native users face challenges with chain preferences. Chainalysis reports that 68% of crypto users have assets on multiple chains, creating friction when sending payments to others with different chain preferences.

Regional Stablecoin Preferences​

Different regions have varying stablecoin adoption patterns. In Asia, USDT dominates with 85% market share, while North America prefers USDC. CoinGecko's 2025 report shows these regional preferences create significant payment barriers.

Creator Economy Fragmentation​

Content creators maintain multiple payment profiles across Buy Me a Coffee, Ko-fi, Patreon, and others, forcing fans to register on multiple platforms. According to Influencer Marketing Hub, the average creator maintains 4.3 separate payment accounts.

Core Barriers​

  • Universal Access Challenge: Everyone wants access to dollars or their local currency-backed stablecoins, but infrastructure barriers exist.

  • Wallet Requirement Barrier: You can't send stablecoins to people without crypto wallets, creating a significant adoption hurdle. Statista data shows only 6.7% of internet users have crypto wallets in 2025, despite stablecoin interest.

  • Limited "Walletless" Solutions: Even in walletless solutions like Coinbase email or Mini Pay for Celo, users still need to know email or phone number, revealing personally identifiable information and adding friction.

  • Identity and Security Issues: People are impersonating social accounts for governance and phishing attacks, highlighting the need for real authentication tied to established social identities.

The Contact Information Problem​

Digital Amnesia​

  • In the US, over 82% of parents couldn't recall their child's phone number in an emergency, and over half of men couldn't dial their parents' numbers by memory1
  • Only 62% of emails submitted to validation services in 2024 were valid, reflecting the rapid turnover and lack of permanence in email contacts2

Social Identity Dominance​

People primarily identify contacts through social profiles rather than phone numbers or emails, yet payments still rely on these legacy identifiers.

Social Platform Proliferation​

The average internet user maintains accounts on 8.4 different social platforms in 2025, according to DataReportal's Global Digital Overview.

  • Social-First Connection: 78% of Gen Z and Millennials report sharing social media handles instead of phone numbers when meeting new contacts, according to Pew Research.

  • Cross-Platform Relationship Management: 65% of users report losing contact with friends who switch primary social platforms, creating fragmented social graphs that complicate payments.

  • P2P Transaction Growth: P2P payment volume has increased 37% year-over-year globally, reaching $785 billion in 2025 according to Business of Apps, yet crypto represents only 3% of this total despite superior features.

  • Social Media vs. Banking Access: 72% of global adults use social media (5.6 billion people), while only 69% have bank accounts (5.4 billion), per World Bank Global Findex and DataReportal, creating an opportunity for social-based financial services.

  • Changing Payment Patterns: Micropayments, creator support, and cross-border remittances have grown 43% since 2022, areas where stablecoins excel but lack easy onboarding, according to McKinsey's Payments Report.

  • Settlement Time Frustration: Traditional bank payments take 2-3 days to settle, while stablecoin transactions complete in under a minute, creating significant time value potential.

Core Onboarding Problems​

  • Non-Wallet Users: Most users don't have wallets and can't receive stablecoins. Statista confirms that while 5.8 billion people have smartphones, only 420 million have crypto wallets.

  • Limited Walletless Solutions: Existing walletless solutions (Coinbase, MiniPay) still require emails or phone numbers, which are often forgotten, rotated, or phished—revealing personally identifiable information.

  • Identity Security Issues: Impersonation and phishing are rampant—users need real authentication tied to their actual social identities.

Security Vulnerability Differences​

  • SIM Swap Attacks: Increased 400% in 2024 according to FTC data, while social platforms with 2FA have 99.9% lower successful account takeovers.

  • Advanced Identity Protection: Major social platforms have invested billions in identity verification and 2FA security, creating more secure authentication than email or SMS-based systems. According to Microsoft's 2024 Security Insider Report, platforms with strong MFA implementation experience 99.7% fewer account compromises than those relying on email or SMS verification alone, with Meta spending $5.1B on security infrastructure in 2024.

The Reality: Addresses, Emails, and Phone Numbers Aren't Built for This Generation​

  • Contact Information Unreliability: Over 82% of parents in the US can't recall their child's phone number in emergencies, and only 62% of emails submitted to validation services in 2024 were valid12

  • Social Platform Scale: Social has outpaced traditional banking—billions have WhatsApp or Facebook, but not a bank account.

  • Messaging App Dominance: 91% of internet users globally use at least one messaging app, with WhatsApp alone reaching 3 billion users in 2025, according to Business of Apps.

  • Direct Social Communication: 76% of internet users communicate with friends primarily through social messaging apps rather than SMS or email, per Pew Research.

  • Global Social Media Scale: 5.6 billion people use social media globally (72% of the world population), creating massive potential for social-based payments, according to DataReportal's 2025 Digital Report.

  • Friend Network Distribution: The average person has contacts spread across 5.3 different communication platforms, creating significant friction for payments, according to GWI's Social Media Trends 2025.
