Requested by Anu Hariharan · ycombinator.com/rfs

Build a compliant, AI-native stablecoin financial platform for global businesses that bridges regulated finance and crypto-native capital efficiency. Objective: Create a programmable treasury and financial services layer built on stablecoins that: - Moves money globally in real time - Unlocks yield and capital efficiency unavailable in traditional banking - Provides access to tokenized real-world assets - Operates within emerging regulatory frameworks - Feels as safe and compliant as traditional finance This is not just a payment processor. It is the financial services layer on top of stablecoin infrastructure. Core vision: Businesses should not have to choose between: - Safe but slow, low-yield traditional banking - High-risk, unregulated crypto tools This platform sits in the regulatory middle ground and offers: - Compliant stablecoin treasury accounts - Yield-bearing cash management - Access to tokenized real-world assets - Programmable cross-border settlement - Transparent on-chain traceability Core capabilities: 1. Compliant Stablecoin Treasury Accounts - KYB onboarding with jurisdiction-aware compliance workflows - Custodial and non-custodial wallet options - Segregated treasury accounts per entity - Double-entry internal ledger synced with on-chain records - Full auditability for regulators and finance teams 2. Programmable Cross-Border Payments - Invoice creation in fiat with stablecoin settlement options - Real-time payment routing across chains and liquidity venues - FX quoting and settlement preview - Smart routing based on speed, cost, and reliability - Full traceability from invoice to on-chain confirmation 3. Yield and Capital Efficiency Layer Instead of idle treasury balances: - Route stablecoin balances into compliant yield sources - Offer transparent yield strategies (e.g., tokenized T-bills, regulated lending pools) - Display risk tier per strategy - Daily liquidity view and instant withdrawal options - Automated yield allocation based on treasury policy 4. Tokenized Real-World Asset Access Allow businesses to allocate excess treasury into: - Tokenized short-term government debt - On-chain credit instruments - Compliant RWA funds - Structured yield products All access must include: - Risk classification - Liquidity terms - Counterparty transparency - Jurisdiction compliance mapping 5. Treasury Control and Risk Management - Real-time view across chains and wallets - Liquidity forecasting - Counterparty exposure tracking - Stablecoin depeg monitoring - Automated rebalancing rules - Policy-based approval thresholds Roles: - org-admin - finance-manager - accountant - approver - auditor - compliance-officer 6. Compliance and Safety Infrastructure - Jurisdiction-aware transaction screening - Sanctions monitoring - Manual review queue for high-risk transactions - Suspicious activity workflow - Full audit log for every movement - Reporting exports aligned with traditional accounting systems 7. Unified Ledger and Reconciliation - Double-entry internal ledger - On-chain reconciliation mapping - Fiat-stablecoin equivalence tracking - Settlement lifecycle tracking: invoice → payment intent → on-chain transaction → reconciliation status 8. Observability and Controls - Alerting for failed settlements - Compliance hold notifications - Stablecoin risk alerts - Yield strategy risk changes - Liquidity stress monitoring Data model: - organizations - wallets - counterparties - invoices - payment-intents - settlements - exchange-quotes - treasury-positions - yield-allocations - rwa-positions - approvals - compliance-cases - audit-logs - ledger-entries Infrastructure requirements: - Secure custody integrations - Strong permissioning - Segregated tenant architecture - Deterministic ledger replay - High-availability payment routing - Regulatory reporting readiness Positioning summary: This platform is not just faster payments. It is a compliant, programmable financial layer built on stablecoins that enables: - Real-time global settlement - Yield-bearing treasury accounts - Access to tokenized real-world assets - Transparent and auditable capital movement It bridges the gap between traditional banking and crypto-native financial infrastructure — giving businesses both safety and upside. Create a modern startup design inspired by Y Combinator (YC) companies. Choose one bright primary color and build a clean, minimal color scheme around it. The design should feel bold, simple, and product-focused with strong typography, generous whitespace, and clear hierarchy.
