Lens vs. Farcaster

From Bankless By William M. Peaster

There's big news in the crypto social scene today. Lens just launched permissionless signups 👀

This means that anyone can now create a Lens profile without needing an invite, opening up the decentralized social network to a broader audience. 

Accordingly, this update brings Lens to par with Farcaster, which rolled out permissionless access in October 2023 and is the current king of the hill among crypto social platforms. 

Farcaster has seen explosive growth since then, particularly after the launch of  Farcaster Frames —interactive postable apps—earlier this year. 

So the main question right now is clear: can Lens catch up to Farcaster’s traction with its own second wind now that it’s gone permissionless?

So the main question right now is clear: can Lens catch up to Farcaster’s traction with its own second wind now that it’s gone permissionless?

I think it’s possible, so let’s dig in and compare the two rising networks to see why. 

The Main Philosophical Similarities

Lens and Farcaster are decentralized social graph projects and share several similarities as they both aim to redefine the landscape of social networking. Here’s how they are most alike:

The Main Architectural Differences

The smart contracts of Lens are deployed on Polygon, while Farcaster's smart contracts are deployed on the Optimism Layer 2 (L2) scaling solution. These networks allow for bypassing the congestion and higher costs that can come with using Ethereum directly while still being anchored to the L1. 

Beyond their differing chain foundations, both Lens and Farcaster also approach handling data in unique ways via Momoka and Farcaster Hubs, respectively:

Decentralized Identity and Account Creation

Lens and Farcaster also rely on distinct systems for identity management. Here's a quick overview of their approaches:

Farcaster: Accounts and Usernames

Lens: Profiles and Handles

The Onboarding Flows

As of today, anyone can visit  lens.xyz  to create a Lens profile. There is a flat fee of 10  MATIC —or roughly $10 USD at the time of writing—to mint a profile, which can optionally be paid via credit card. With a profile in hand, you can start using apps around the Lens ecosystem. 

In-kind, Farcaster currently allows  free signups  via its most popular front end, Warpcast, for mobile users in supported countries. For others outside of this scope, there’s a $5 USD onboarding fee to get started in the app. 

Comparing the Lens and Farcaster Apps 

Developed by the Farcaster team, the aforementioned  Warpcast  is the Twitter-like flagship app of the Farcaster ecosystem and was built to demonstrate and become a hub for the social protocol’s early capabilities. It’s complemented by a growing scene of alternative third-party apps, like  Farcord  and  Supercast . 

In contrast, the Lens team purposely hasn’t created a main frontend for its protocol in order to leave the Lens app scene entirely up to community builders. There are a handful of projects that have been gaining early traction here, namely  Hey  (a desktop Lens client),  Orb  (a mobile Lens client), and  Buttrfly  (a Lens social explorer).

Lens Open Actions vs. Farcaster Frames

Last month, Farcaster took the crypto social landscape by storm when it released support for Frames. Built as an extension of Facebook’s old  Open Graph  protocol, Frames enable embedding interactive apps directly into Farcaster-based social feeds, with actions triggered by button presses that can update a Frame’s content in real-time. 

This design offers a blend of front end experience rigidity and backend execution flexibility, where the frontend is defined by embedded URLS, and the execution logic is handled under the hood via custom functions. As such, Frames can be used for posting anything – from one-tap NFT mints to voting polls. 

Lens has its own native answer here,  Open Actions , and this architecture is used to enable smart contract calls to be embedded directly into Lens onchain publications, e.g., comments. This capability allows developers to integrate specific contract calls, parameters, and even sophisticated logic like token-gating or follow-gating within a social context. 

The “Tipping” Open Action is an early example, through which a poster can include a module that directs tips to a specified receiver address. Yet, as is the case with Frames, the possibilities around Open Actions are wide open. 

Of course, it’s worth noting that ultimately neither of these systems are siloed from each other and can be used interoperably, e.g., chaining actions through both Lens and Farcaster. The  Open Frames  effort, which allows a lighter version of Frames to work outside Farcaster, also suggests more interoperability is coming at this crossroads. 

Future Outlooks

Farcaster currently has a base of  +200,000 users , many of whom have joined over the past month as onboarding has become smoother and Frames have become more popular. The protocol’s permissionless foundation has proven itself amid this ramping up, and it seems that breakout success could be on the horizon. 

Now, it’s time for Lens to also prove itself in the wild. To be sure, Farcaster had a head start, but Lens has already racked up  +125,000 profiles  before going permissionless, indicating it has a solid base to lean on. And since Lens offers some of the same general ingredients as Farcaster, Farcaster’s early success suggests Lens can also surge thanks to similar tailwinds. 

Will one eventually win out over the other? Maybe so. Farcaster’s decidedly the king of the hill for now, and that hill is widening to other ecosystems like  Solana . But keep in mind that the crypto social scene is still very nascent, so it seems likely that the rising popularity tide here will lift both boats through the foreseeable future. 

Additionally, web3 crossposting apps like  Yup —which lets you post across Twitter, Farcaster, and Lens simultaneously—and projects like Open Frames suggest that Farcaster and Lens can grow in parallel and in a complementary fashion, at least over the near term. 

Whatever happens, the prospects are looking good for both projects right now, so don’t write off Lens just yet!
