“Earlier this year, we decided to focus on improving trading features – make trading easier, more social, and more fun for everyone. Choosing an API provider was easy - we went with 0x because we already trusted the brand and knew it would let us focus on creating a great UX instead of building infrastructure from scratch. Over the past few weeks, we’ve been growing massively, and the timely support from the 0x team has been amazing.”

- Wijuwiju, Co-Founder of Interface

Highlights

• Interface, a Web3 social app for Ethereum, uses Swap API v2 to power swaps and copytrades directly in the social feed. Copytrading on Interface allows anyone to repeat a swap after someone else, with the transaction visible to all Interface users in the feed.
• Wide coverage: With support for 7+ million tokens across 10 chains, 0x v2 provided Interface with the wide coverage needed for users looking to seize the latest onchain opportunities.
• Powerful monetization: Interface has been able to easily implement and experiment with swap fees thanks to 0x v2’s powerful out-of-the-box monetization features.
• Easy integration: From start to finish, the Interface team was able to integrate 0x v2 in under 1 month.‍
• Rapid Adoption: Interface has gone from $0 to over $3.5M in social trading volume in just 70 days since the launch of swaps, with daily volume hitting $500k near the end of November.

What is Interface?

‍

‍

Interface is social network and block explorer all wrapped into one - offering a new social experience for the way onchain users interact with the Ethereum ecosystem.

Interface enables users to easily discover what’s happening onchain, including:

• Following wallets and tracking their activity from a single feed
• Syncing their social graph, such as importing friends from Farcaster, and finding new connections
• Discovering opportunities, copytrading, and making friends along the way

In this case study, we’ll take a deeper look at how Interface is transforming Ethereum into a user-friendly social network and how 0x v2 helps enable a new tool for onchain discovery by powering swaps and copytrading directly in the social feed.

‍

Onchain discovery

Ethereum is a complex ecosystem, full of endless opportunities, challenges, and exploration.

Navigating Etherscan, tracking wallets, and aggregating all of this onchain activity is difficult, requiring deep knowledge of the Ethereum ecosystem. Ethereum itself is a form of a social network, with users able to trade tokens, share art, and connect with new people.

However, this experience is still fragmented across many different tools and interfaces. On top of that, the crypto space can be overwhelming, with new tokens, drops, NFTs, and more on daily basis.

Interface was built with the goal of connecting people through a readable, navigable, and discoverable Web3 interface - bringing together all of this activity with a universal frontend tailor-built for social use cases. Interface, along with SocialFi more broadly, presents a new way for people to discover what’s happening onchain.

‍

‍

Similar to how 0x aggregates liquidity, Interface aggregates wallet activity across sources (chains, protocols, and platforms), indexes and parses it individually, and then turns in into a user-friendly, discoverable social feed - aiming to surface and visualize the social graph of Ethereum.

What does this enable? Instead of relying on complex analytical dashboards and tools, users can rely on their community - tracking what they are interacting with, what tokens they are buying, how they are performing, copy trading them, and much more. By making information onchain more intuitive and accessible, Interface helps level the playing field.

Initially launched in 2022, Interface started with a simple transaction feed where users could see what wallets swapped, how they voted, and what contracts they interacted with. In August, the team began looking at integrating trading directly within the app, realizing that swaps offered the potential for a new sort of onchain discovery.

But, just as social information is fragmented across the Ethereum ecosystem so too is liquidity - spread across many different chains, DEXs, and tokens.

Interface was looking for a trustworthy DEX aggregator that would enable them to quickly integrate powerful swaps with wide market coverage and deep aggregated liquidity, without the need for additional engineering resources. Interface also needed the ability to easily collect and pass through fees on swaps.

Their search for a swap provider with deep expertise in the DEX aggregation and a holistic feature set that met their needs led them to 0x. With 0x building in the space since 2017, the team trusted 0x’s reputation for providing reliable, industry-leading aggregation products.

Social trading powered by 0x

Interface launched swaps powered by 0x v2 in September. With the integration, users can swap tokens on Ethereum, Base, and Optimism directly in the Interface social feed - bringing the power of DeFi together with a decentralized social network. To access swaps, users can tap on any token in the transaction feed or on any user profile. Leveraging 0x’s trust in the space, Interface clearly displays 0x as the swap provider in their UI.

‍

‍

With a single integration, v2 provides Interface with the:

• Best all-in prices across every trade size.
• Widest coverage with support for 7+ million tokens across 10 chains, providing the coverage needed for users looking to seize the latest opportunities. And with v2, new chains and liquidity sources are integrated rapidly, enabling Interface to offer continuously improving coverage.
• Powerful monetization features that make implementing and experimenting with swap fees easy.

Following the success of its swap feature, Interface also wanted to offer the ability for users to copytrade the wallets they track and surface the underlying social interaction between users.

Here’s how it works: Copytrading on Interface allows anyone to repeat a swap after someone else. The person being copytraded gets notified of the copytrade and the transaction is visible to all Interface users in the feed.

‍

‍

Copytrading has already proven to be a powerful new onchain discovery tool, allowing users to easily see who copied whom and navigate to the source of the original signal. With one seemingly simple new feature, a new social graph was born, enabling an entirely new way to explore Ethereum.

‍

‍

Experimenting with novel monetization strategies

Swaps and copytrading have also given Interface the ability to experiment with novel monetization strategies. Interface collects a 0.69% fee on regular swaps. For copytrades, that 0.69% fee is distributed to the wallet being copied, which can all be seen from an app-wide leaderboard that allows users to both track and discover new wallets based on who is being copytraded the most.

‍

‍

In the future, Interface plans to fairly reward every participant of the swap, from the application layer to all of the swap participants, believing that people are willing to pay a small fee for the value of discovery.

Copytrading on Interface has taken off, with over $3.5M in volume in just 70 days since the launch of swaps, and daily volume hitting $500k on Base near the end of November. Thanks to copytrading, Interface has seen the rapid dissemination of new coins on the app, with some new tokens starting on Interface and eventually reaching the top of DEXScreener.

Offering seamless swaps for millions of tokens to users has been a major unlock for Interface, enabling Interface to launch social trading, drive novel token discovery mechanics, and monetize their app.
