The XRP Ledger (XRPL) may be on the verge of a significant upgrade in how it handles transaction fees, thanks to a recent proposal from Ripple’s Chief Technology Officer, David Schwartz. His idea? A fee refund model that returns unused portions of transaction costs to users—potentially reshaping fairness, efficiency, and user experience on the network.
This forward-thinking suggestion emerged from an ongoing technical discussion within the XRPL developer community, centered around the Xahau Hook engine—a powerful feature enabling smart contract-like functionality on XRPL. While Hooks offer enhanced programmability, they come with a notable trade-off: users pay a fixed execution fee calculated based on worst-case computational scenarios, regardless of actual resource usage.
The Problem with Current XRPL Fee Mechanics
When a user triggers a Hook on the Xahau network, the system pre-calculates a maximum compute cost and adds it as a fixed fee on top of the base transaction fee. This design ensures predictability but often results in overpayment.
As Mayukha Vadari, a key XRPL ecosystem developer, pointed out:
“The transaction fee is just the worst-case scenario compute on the hook, so you’re almost always paying too many fees.”
This stands in contrast to Ethereum’s gas model, where users set a gas limit and are refunded for any unused portion. On XRPL, however, every extra drop of XRP spent is permanently burned—even if it wasn't needed.
This has led to growing concerns about cost efficiency and user fairness, especially as decentralized applications (dApps) increasingly leverage Hooks for complex logic. Vet, co-founder of the NFT platform XRP Cafe, posed a simple yet powerful question: Why can’t XRPL refund overpaid hook fees?
While Vadari explained that the static fee is intentional—designed to simplify consensus and prevent computational abuse—the debate highlighted a clear tension between system stability and user equity.

A New Vision: Dynamic Fee Refunds
Enter David Schwartz. Weighing in on the conversation, he proposed a novel solution that could reconcile both priorities: charge users upfront but refund any excess fees beyond what’s necessary to include their transaction in the ledger.
His model works like this:
- All transactions specify a maximum fee they’re willing to pay.
- After consensus determines the final transaction set, the network calculates the minimum fee required to get into that ledger.
- Every included transaction pays only that minimum rate.
- Any amount above it is automatically refunded to the sender.
“Compute the fee level required to get one more transaction into the ledger after the consensus transaction set is determined and rebate any fee above that level.”
— David 'JoelKatz' Schwartz
This approach maintains incentive alignment—users who bid higher still gain priority during congestion—while eliminating unnecessary burn. It introduces a form of dynamic pricing without sacrificing XRPL’s speed or finality.
Schwartz acknowledged potential challenges, particularly around consensus integrity. Since validators must agree on which transactions make it into each ledger, disagreement over the "minimum required fee" could theoretically lead to ledger forks—a critical risk in any blockchain.
To mitigate this, he suggested a fallback mechanism: instead of calculating the exact marginal cost, refund any fee above the median of all accepted transaction fees in a given ledger. This method is simpler, more predictable, and avoids inter-validator disputes.
He also recommended disabling refunds during periods of low network activity—say, when fewer than 10 transactions are included per ledger—to prevent edge cases and maintain economic stability.
Why This Change Could Be Game-Changing
At its core, this proposal addresses a fundamental issue in blockchain economics: efficiency vs. fairness.
Currently, XRPL burns all transaction fees, contributing to deflationary pressure on XRP supply. While beneficial for tokenomics in theory, this model penalizes users for prudent overestimation—something Ethereum avoids through its refund mechanism.
Schwartz isn’t advocating for eliminating fee burns altogether. Instead, he envisions a smarter system where only the necessary portion of a fee is burned, and surplus is returned. This preserves scarcity while improving user experience.
For developers building on XRPL, especially those using Hooks for DeFi protocols, NFT marketplaces, or cross-chain applications, this change could drastically reduce operational costs. It would also make gas estimation less stressful and more forgiving—similar to the UX users expect from modern dApp environments.

Frequently Asked Questions (FAQ)
Q: Will this proposal eliminate all transaction fees on XRPL?
A: No. Users will still pay fees to secure network resources. Only excess amounts above what’s needed for inclusion will be refunded.
Q: How will refunds affect XRP’s deflationary model?
A: The overall impact depends on implementation scale. Since only unused portions are rebated, the burn mechanism remains active—but becomes more efficient and user-friendly.
Q: Could this lead to spam attacks or network abuse?
A: Unlikely. Transactions still require a minimum fee to enter the mempool, and validators retain control over ledger inclusion rules.
Q: Is this idea officially part of XRPL’s roadmap?
A: Not yet. It’s currently a community-discussed proposal led by David Schwartz. Formal adoption would require extensive testing and consensus among node operators.
Q: How does this compare to Ethereum’s EIP-1559?
A: While both aim to improve fee predictability, Schwartz’s model focuses on refunds rather than base fee burning. It’s more aligned with dynamic market pricing than fixed base fees.
Q: When might such a change go live?
A: There’s no timeline yet. As with all protocol upgrades, it would need thorough review, simulation, and approval via XRPL’s decentralized governance process.

Final Thoughts
David Schwartz’s fee refund concept isn’t just a technical tweak—it’s a philosophical shift toward greater user empowerment on the XRP Ledger. By aligning incentives between users, developers, and validators, it offers a path to a more equitable and sustainable ecosystem.
While still in early stages, the fact that such ideas are being openly debated—and originate from Ripple’s top technologist—signals strong momentum behind continuous improvement on XRPL.
As blockchain networks mature, small changes like this can have outsized impacts. If adopted, this model could position XRPL as one of the most user-centric Layer 1 blockchains in existence—balancing innovation with integrity, and efficiency with fairness.
