“Gasless swaps have helped us create a simpler trading experience, where users can focus more on trading and less about network fees. Network fees have been a top pain point for the past few years, and giving users more flexibility around network fees is a huge UX unlock.”

- Claudia Haddad, Product Manager at Coinbase Wallet

Challenge: Optimizing the user experience

Coinbase has been an industry leader in onboarding users into Web3 by building products with real-world utility and best-in-class user experience. In 2021, Coinbase wanted to upgrade their Wallet experience to allow users to trade any token from day 1.

Their search for a swap provider with expertise in DEX markets and a deep understanding of API infrastructure, reliability, and enterprise-grade security led them to 0x.

"0x has the most extensive and reliable DEX API service in the Web3 ecosystem, backed by a professional and responsive team. It’s been a pleasure working with them to launch our DEX features on Coinbase Wallet." - Sid Coelho-Prabhu, Director of Product at Coinbase

As Coinbase Wallet evolved and matured, their team began investigating opportunities to optimize the user experience, particularly in the trading flow funnel. The expansion of our multi-chain world has increased the burden on users, requiring them to hold and maintain balances in multiple native tokens to cover gas as they move from ecosystem to ecosystem.

Insufficient gas is a major source of friction in DeFi with a significant impact on conversion. According to Coinbase Wallet, 69% of Ethereum swaps encounter a ‘not enough gas’ error when the user starts the trade, a large impediment to conversion. Coinbase Wallet was looking for a solution to abstract away the complexities around decentralized trading.

Solution: Gasless swaps and approvals

Gasless API enabled Coinbase to build on the foundation of a user-friendly experience by offering another powerful option in their trading flow: gasless swaps and approvals.

We’ve all been there - you go to make a trade only realize you don’t have enough gas when you go to submit it.

Gasless API works to supplement the existing trading experience in Coinbase Wallet powered by Swap API. When a user goes to complete a transaction and doesn’t have enough gas, Coinbase Wallet will automatically switch over to the gasless experience, allowing them to quickly complete the trade without the need to top up for gas.

When a gasless trade is made, Gasless API covers the gas fee up front, and token approvals are combined into the transaction. This cost is then wrapped into the trade and paid by the user in the form of the token they’re trading, significantly simplifying the trading experience and eliminating one of the top causes of incomplete trades.

On top of the benefits of gasless swaps, Gasless API also helps improve the trading experience for Wallet users with:

• Improved trade reliability: On average, 8-10% of DEX transactions fail, and during periods of network congestion that can spike to as high as 20%. Gasless API can stop potentially bad transactions before they’re even sent, saving the user gas fees and headaches.
• Faster trade confirmations: Sometimes just a few cents in gas fees can be the difference between a transaction going through quickly and or getting stuck in the mempool. Gasless API dynamically adjusts gas fees in real time by optimizing for speed, making trades 2x more likely to land in the next block.
• Protection from MEV attacks: Sandwich attacks target transactions in the public mempool, resulting in worse prices and a poor experience for users. Gasless API protects users from sandwich attacks by leveraging the latest advancements in the MEV space.
