# Follow the users Source: https://blog.spindl.xyz/p/follow-the-users ## Summary Spindl, an onchain growth measurement firm, used first-touch attribution data from August 9 to September 7 to show which Base dApps brought in their users. Since Base launched to mainnet in early August, about 1,200,000 wallets have onboarded and roughly half a billion dollars in tokens have been bridged. The analysis found that the Onchain Summer site's mints, particularly anotherblock and FWB, were among the biggest drivers of Base adoption. The article says FWB's mint had a Base retention rate of 38%, and that Friend.tech drove little other Base usage. It also argues that the onchain ecosystem has a publisher problem, since few paid media options exist to drive user growth. ## Article All the Base dApps whose users’ first touchpoint was Onchain Summer.

Text within this block will maintain its original spacing when published Reluctantly crouched at the starting line Engines pumping and thumping in time The green light flashes, the flags go up Churning and burning, they yearn for the cup Cake, 'The Distance' We at Spindl have been very excited about Base. Built on the open-source OP Stack and incubated by Coinbase, with integrations into Coinbase products, the new L2 Base is the perfect storm of consumers, functionality and blockchain infra to indeed make ‘onchain the new online.’ But how’s it doing? Since launching to mainnet in early August, Base has seen almost 1,200,000 wallets onboard to the chain, and about half a billion dollars in tokens bridged. Dozens of projects have announced Base support (including Spindl), and the chain has taken its place alongside more established ecosystems like Arbitrum and Polygon as a place you need to deploy. Such meteoric growth among competing dapps on a new chain presents an interesting case study for what Spindl specializes in: onchain growth measurement. It’s rare to have developers arranged at a starting line, raring to go like in the Cake song above, and then see how far they get given the various growth strategies deployed. It’s also a showpiece for what Spindl does best: onchain measurement and attribution. Forget for a moment the flurry of regular actions users constantly do, like page views, clicks, and game plays (all of which Spindl also tracks). Even limiting ourselves to transactions on a new blockchain, a user will transit a unique journey—mints, swaps, bridging—until landing on the virtual doorstep of your application. How did they get there, and whom do we thank for their arrival? That function is described by the oft invoked (and misused) term of ‘attribution,’ a core concern of the Spindl product. Everything in the Web 3 timeline is the reverse of Web 2: infra comes before consumer adoption, intricate economics before viral usage. It may well also be that precise attribution precedes the eventual advertising models that emerge. What’s the tl;dr? In Web 2, attribution providers like Branch or AppsFlyer would run a simple ‘last touch’ attribution model to crown the winner of the CPA (cost-per-action) bounty for the desired user action (e.g. a purchase or install). Whoever touched the user last got the prize for acquiring them, and centralized intermediaries like Facebook and Google built trillion-dollar valuations based on winning attribution showdowns. Simple as. In Web 3, since the attribution winner will often be rewarded with an ongoing percent of user revenue, advertisers seem more comfortable with a first touch model that privileges whoever first brought in the transacting user1. If a project is running a multi-channel strategy of referrals, organic Twitter poasting, regular paid ads and whatever else the marketing person cooked up, only an attribution system can disentangle the touchpoints into something causal and actionable. Take a relatively simple growth hack: theOnchain Summer site that Base launched to celebrate mainnet. By mapping each featured mint to an onchain action, we permissionlessly measured the efficacy of the growth campaign. Mints are on the left, and all the dApps those mints drove users to are on the right2. Spindl data shows that anotherblock and FWB were the biggest drivers of Base adoption. An attribution Sankey for Base dApps: On right, the dApp that gained a user; on left, the mint who first onboarded the user (per a first-touch attribution model). Data from August 9th to September 7th. Looking beyond the Onchain Summer site, we can look at all the dApps that onboarded users on Base, and do the same first-touch attribution analysis. This is any smart contract that was a user ‘first touch’ for eventual Base usage, pivoted by the downstream dApp3. If you’re asking the ad-tech boomer question of “you mean to tell me that in a properly-attributed ads model, assuming there was some sponsored app discovery thing running, everyone on the left would be paid by everyone on the right, proportionate to the thickness of the line connecting them?” A dApp-to-dApp attribution Sankey: on right, the dApp which gained a new user; on left, the dApp that onboarded the user to Base, per a first-touch attribution model. Data from August 9th to September 7th. Yes, that’s exactly what this Sankey diagram shows. Each flowing line is the attributional weight of an end user for a dApp on the right to someone on the left who first brought them onchain and eventually to that final dApp. If that leftmost NFT or dapp were an ad in Web 2 land, it’s who you’d pay for the user. This is the user acquisition graph for the most popular dApps and NFT projects, during the first three weeks of Base. As is clear, some first-touch dApps are much better at keeping users onchain than others. Friend.tech, the viral social app, does not drive a lot of other Base usage, even as the app itself has grown in popularity (this is while still joining to the original user wallet, not just the app-specific wallet). The Friend With Benefits (FWB) mint on On Chain Summer was particularly good at driving Base users to other dapps, with a Base retention rate of 38%. First-touch attributional comparison of Layer 3 Base-related quests and the Onchain Summer mint site. ‘Other’ is any other upstream user source. Data from August 9th to September 7th. Layer 3, a questing platform, ran a collection of Base-specific quests. As you can see from the left-hand side of the Sankey above, the Layer 3 campaigns drove about as much Base usage as the Onchain Summer website itself (‘others’ was every source except Layer 3 or Onchain Summer). We’ve measured the retention and return-on-advertising-spend (ROAS) of Layer 3 quests before, and have shown they can be an effective user acquisition mechanism. There will clearly be a role for third-party publishers to permissionlessly (and gainfully) onboard new users onchain. Right now however, with the possible exception of quests, the onchain ecosystem has a serious ‘publisher problem’. Even projects with marketing budget have little (if any) onchain paid media they can buy to drive growth. Like it or not, publishers like Facebook and Google were the engines for Web 2 growth, and even in decentralized form, nothing has really emerged at that scale (yet) in Web 3. Spindl solves the measurement and referral payout problem, but there isn’t much to measure without a publisher sending users down the funnel. It’s our hope that by providing just that measurement, interesting collaborations can emerge between onchain-native publishers good at making users stick around, and apps looking to give those users something to do onchain. Everything in the Web 3 timeline is the reverse of Web 2: infra comes before consumer adoption, intricate economics before viral usage, everything literally the reverse order of Web 2 history. It may well also be that, the reverse of Web 2, precise attribution precedes the eventual advertising models that emerge, mapping out the trails that both users (and money) followed.
