Going to the opening of the Lausanne (Switzerland) Chapter Kick-Off of the "Agent Economy Association", luma.com/w1713cmj.The agent economy is one of the 3 pillars of our thesis "pre-seed everyday finance" at Olive Capital.Will you be there? Let's meet in Lausanne.
Welcome back to the Farcaster Builders Series, where we go behind the code to meet the builders shaping the Farcaster ecosystem.
In this third and last episode episode, we sat down with JUSTIN AHN, co-founder of QUIDLI.

This limited series was recorded at an interesting moment, just before Neynar’s acquisition of Farcaster and its refocus on builders. The timing turned out to be sharp. Inside, we go deep on the strategies, timing, and mental models of the founders architecting the next generation of onchain experiences, with
* EP#1: Kaloh building Indexy: “From speculation to modern (and agentic) portfolio management” (listen),
* EP#2: Atown building Emerge: “The antidote to AI slop, and the future of onchain personalization” (listen), and
* EP#3: for the final episode, we are looking today at the infrastructure layer of social finance with Justin (@ahn.eth) building Quidli: “The plumbing of social finance”.
Who is Justin?
Justin is the co-founder of Quidli, and he has been living on the internet longer than most people in crypto have been paying attention to it, since 1995. He went on to work in corporate finance, then built one of Vietnam’s first nationwide e-commerce platforms, before spending years moving between countries and experiencing firsthand how broken cross-border payments are.
He met his co-founder Guillaume in France’s early Ethereum community. Together, they share a conviction about self-sovereign internet and frictionless payments that has shaped Quidli from day one.
What is Quidli?
At its core, Quidli is a social graph register, a way to bring your social connections onchain and make them portable, interoperable, and ultimately yours.
The problem it is solving is one every internet user intuitively understands but rarely articulates: your audience, your network, your community, none of it belongs to you. It lives on someone else’s server. Change platforms and you start from zero. Get banned or locked out and it is gone. X is the clearest example today: it is hard to leave not because the product is great, but because your network is trapped there.
Quidli’s answer is a register that lets you duplicate your social graph onchain, making it censorship-resistant and portable across any platform you use.
The immediate product built on top of this is a mini-app that lets you send tokens to people using their social handle, no wallet addresses, no seed phrases, no ENS required. If you follow someone on Farcaster, Telegram, Discord, or even email, you can send them tokens directly. You already know their handle. That is enough.
Why this, why now?
The ENS comparison is worth dwelling on. ENS was supposed to abstract away the complexity of blockchain addresses, and in some ways it did. But ENS became, as Justin puts it, a vanity project. A personalized license plate. Knowing that Vitalik is vitalik.eth only helps you if you already know who Vitalik is. It does not help you send tokens to someone you met in a Telegram group.
A social register solves this differently. It starts from the connections you already have, on the platforms you already use, and maps them to onchain addresses. It is the difference between DNS (which actually works) and a vanity URL (which is just aesthetics).
The payment rails follow naturally. Once your social graph is on-chain, value transfer becomes a native feature of your network, not an afterthought bolted onto a wallet interface. That is the convergence Justin sees accelerating: social and finance, at the individual and org level.
Three key insights from this episode
1. Your social graph is your most valuable on-chain asset.More than tokens, more than NFTs. The network you have built over years, across platforms, communities, and collaborations, is genuinely irreplaceable. Putting it onchain is not a technical exercise, it is a form of ownership.
2. ENS solved the wrong problem.Readable addresses are useful but identity without social context is not identity, it is just a label. What builders need is a system that starts from real human connections and makes those the unit of trust.
3. Advice for Farcaster builders: wrap, don’t lock.Farcaster is one channel, not the whole game. Build web apps that can be wrapped as mini-apps and deployed across multiple platforms simultaneously. The builders who will win are the ones who treat Farcaster as an entry point, not a ceiling.
It is a very useful episode for understanding how portable social graphs can abstract away complex blockchain UX to enable seamless value transfer across any platform.
Thanks Justin, and thanks to all three founders who took the time to be part of this series.
