Universal Financial Abstraction: The router treats all financial platforms the same way, whether you’re moving between Chase and Coinbase or Ethereum and Solana.
What is the Router?
The Transfer Router is Fellow’s proprietary infrastructure that creates a universal abstraction layer over the entire financial ecosystem, enabling seamless money movement between platforms that were never designed to work together. The Router triggers a seamless flow-of-funds that to the user appears as an instant transfer but involves an intricate set of moving parts.Intelligent Routing
Automatically selects optimal paths between any two financial platforms based on speed, cost, and liquidity availability
Protocol Translation
Seamlessly converts between traditional banking rails (ACH) and cryptocurrency networks without user complexity
Instant Settlement
Provides immediate access to funds through short-term credit instruments while background settlement occurs
Universal Connectivity
Single API that works with 10,000+ banks, exchanges, and financial platforms through unified infrastructure
Router Architecture
The Fellow Router operates across multiple interconnected layers to provide seamless cross-platform transfers:
How Routing Works
The router handles four main transfer types with specific pathways for each:- Fintech → Fintech
- Fiat → Crypto
- Crypto → Crypto
- Crypto → Fintech
Fintech to Fintech (Robinhood, etc.)
- User initiates an ACH transfer from a Fintech to their Fellow bank account
- Router captures the intent (destination: Robinhood account)
- We make instant transfer using user’s credit card for immediate settlement
- Funds arrive in Robinhood instantly with minimal latency
- When ACH settles (2-4 days), it pays off the credit card balance
Technical Implementation
Settlement Layer Architecture
The router operates on a three-tier settlement system that provides instant user experience while managing backend complexity:- Tier 1: Instant Layer
- Create 2-4 day credit instruments backed by pending ACH
- Real-time credit assessment via Fellow’s AI
- Provide immediate fund availability in destination accounts
- User experience identical to instant transfers
- Tier 2: Settlement Layer
- Traditional ACH/wire transfers initiated automatically
- Blockchain transactions queued and optimized
- Cross-platform API calls for balance updates
- Settlement monitoring and exception handling
- Tier 3: Reconciliation
- Credit instruments retired upon ACH completion
- Failed transfers trigger standard collection processes
- Profit/loss allocation to liquidity providers
- Regulatory reporting and compliance documentation

Liquidity Pool Integration
Single Pool Architecture

- Universal Coverage: USDC pool handles conversions for all transfer types via our integration partners
- Simplified Management: One pool means clearer economics and easier risk management
- LP Deposits: Users stake USDC to earn yield from transfer fees
- Credit Backing: Pool provides instant liquidity when users request transfers
- Settlement: Pool gets repaid when ACH transfers complete (2-4 days)
- Yield Distribution: Transfer fees flow back to LPs proportional to their stake
- Dynamic Rates: Interest rates adjust based on pool utilization
- Risk Controls: Per-user credit limits and automated default recovery
- Reserve Management: Portion of fees held in reserve for stability
