BACKGROUND
This paper introduces Fiatrouter, a fiat-to-crypto onboarding solution built on Solana, and Framp Relay, an infrastructure layer that enables gasless, token-agnostic utility for on-chain assets. We analyze their architectural design, evaluate usage metrics, and present real-world applications. By leveraging Jupiter DEX’s liquidity routing, these tools extend the utility of on-chain assets beyond basic trading, enabling users to pay for services and goods directly with SPL tokens. Preliminary data from 273 users and early integrations with platforms like Airbills Pay and Itiza demonstrate the feasibility and demand for broader token utility.
1. Introduction
1.1 Problem Statement
The vast majority of on-chain tokens are currently idle, utilized mostly for speculative trading, governance, or holding for future value. There is very little real-world utility. Despite Solana’s high liquidity, users often experience a fundamental limitation—they cannot utilize non-native tokens (e.g., meme coins, microcaps, specialized community tokens) for ordinary transactions like subscriptions, airtime, or e-commerce.
This is more than simply a user experience issue; it is an infrastructural gap.
A wide range of dApps and services only accept a limited range of payment tokens, forcing users to manually trade their assets or leave their tokens unused. In several known cases, it is due to complexity, slippage worries, or a lack of integration. Mainstream users cannot utilize assets for transactions; millions of tokens are stuck. There ought to be a solution for mainstream users to utilize these tokens for different on-chain transactions.
1.2 Overview of Fiatrouter
Fiatrouter was developed to simplify fiat-to-crypto onboarding, using card-based flows familiar to mainstream users. Integrated with Jupiter DEX, it allows seamless conversion to any SPL token with deep liquidity. To enable users to perform token transfers and payments without holding SOL, Fiatrouter builds on this integrated Jupiter DEX by providing a gasless swap mechanism to users. This is called the Framp Relay. Framp relay enables token spending across various real-world scenarios by abstracting transaction complexity away from the user.
2. Related Work
Several platforms aim to bridge fiat and crypto, including:
-
MoonPay and Ramp: These focus on fiat-to-crypto onboarding with limited token flexibility and centralized compliance.
-
Stripe Crypto APIs: Support USDC-based payments but restrict usage to stablecoins.
Unlike these systems, Fiatrouter and Framp Relay are fully integrated with Jupiter DEX to provide flexible liquidity routing and support for any SPL token, coupled with fee abstraction for the end-user.
3. Architecture
3.1 Fiatrouter
Fiatrouter connects traditional card payment infrastructure to the Solana blockchain. Upon user payment, funds are routed via an off-ramp to stablecoins, then converted to the user-selected SPL token using Jupiter’s smart liquidity routing. This process abstracts away the complexity of token selection and conversion.
3.2 Framp Relay
Framp Relay enables users to perform transactions using any SPL token, without holding SOL. It does this via a relayer mechanism:
-
The user signs a transaction in which the relayer pays the SOL fees.
-
In return, the user transfers an equivalent value in their preferred SPL token.
-
Jupiter’s gasless swap infrastructure is used to instantly convert tokens as needed.
This architecture makes even illiquid or non-standard tokens usable for direct payments, while maintaining speed and security.
4. Use Cases
4.1 Token-Based Payments
Framp Relay allows users to
-
Pay for airtime, bills, and bets using any SPL token.
-
Book flights and hotel rooms (in partnership with Airbills Pay, in pipeline).
-
Make merchant payments for digital or physical goods.
4.2 Itiza Integration
Itiza Luxury Store integrated Framp Relay to:
-
Allow token-based gifting (e.g., meme coins as luxury item credits).
-
Send airtime or data bundles as token-wrapped digital gifts.
5. User Adoption and Metrics
-
Total Users: 273 unique wallets
-
Daily Active Users (DAU): 150+
-
Average Monthly Volume: $2,000
These early-stage figures show promising retention and indicate a niche but growing demand for real-world token utility.
5.1 Usage Patterns
Users primarily interact with the platform via:
-
Microtransactions (airtime, data)
-
Subscription-like recurring payments
-
Gifting via niche tokens
5.2 Feedback and Constraints
-
Users appreciate fee abstraction.
-
Constraints include initial liquidity for low-cap tokens, and onboarding merchants who accept token-based payments.
6. Challenges & Future Work
6.1 Liquidity Scaling
Enabling payments in any SPL token requires sufficient liquidity on Jupiter DEX. Long-tail token support depends on ongoing market maker participation.
6.2 Merchant Ecosystem
Expanding to more merchants will require standardized tooling and incentives, potentially through SDKs and partner APIs.
6.3 Security
Ensuring relayer integrity and preventing transaction manipulation is critical. Future versions may introduce additional cryptographic guarantees or decentralized relay networks.
6.4 Regulatory Environment
Cross-border fiat integration and token usage in payments will need to navigate evolving KYC and compliance requirements.
7. Conclusion
Fiatrouter and Framp Relay demonstrate the potential for extending token utility beyond trading and speculation. By abstracting transaction fees and leveraging Solana’s DEX infrastructure, these tools transform idle tokens into spendable assets. Early use cases and adoption trends show real-world viability, though scalability and compliance remain challenges to address.
This case study represents a foundational step toward making web3 wallets function as complete financial instruments, not just trading accounts.
