Every DeFi protocol has a marketing budget. Some of it goes to X ads that get scrolled past. Some goes to sponsored posts that get forgotten. And some goes to things like Galxe campaigns, quest platforms, and Discord bots.
Very little of it goes where the developers actually are: GitHub.
Here is a fact that should stop you mid-scroll. Anthias Labs, a $21.86M boutique risk advisory firm, has never raised venture capital, runs no ad campaigns, and has a single-page website with no blog. And yet it counts Aave, Compound, Euler, the Uniswap Foundation, Arbitrum, Optimism, and the Solana Foundation as partners.
How? Through open-source tooling that builds developer mindshare while the rest of DeFi fights over Twitter impressions.
Three tools that do more marketing than most Twitter accounts
Anthias Labs maintains three original open-source projects plus several research papers, all on its GitHub. Each one functions as a silent lead-generation engine.
Flare, a CLI for developers on Solana, is the clearest example. Flare was built with a grant from the Solana Foundation and lets developers send transactions, check balances, generate keypairs, and call Anchor program methods from the command line. It has 28 GitHub stars and 76 commits. Every developer who pulls Flare’s repo or runs flare balance has Anthias’ brand on their terminal.
Flare’s README describes its origin plainly: “The development of Flare was originally funded by a grant from the Solana Foundation to Anthias Labs.” A one-sentence origin story that functions as a partner endorsement, a credibility signal, and a case study, all at once.
Arbiter, described as an “advanced agentic simulation toolkit and sandbox tool for Ethereum”, has 46 GitHub stars on its template repo. It gives Ethereum developers fine-grained control over an EVM to simulate complex DeFi scenarios. Its template shows up when developers search for Rust-based EVM simulation. That is search engine optimisation for a developer audience, and it costs nothing in ad spend.
Arena, a framework to help liquidity providers “refine their liquidity strategies through robust market simulation and analysis”, tackles the same problem from the LP side. If you are a DeFi protocol worried about your liquidity depth, Arena is the tool that positions Anthias as the people who understand LPs better than anyone else.
Between these three, Anthias has built a developer-education funnel that most protocols would pay an agency $20k/month to approximate.
The Uniswap connection
The Uniswap Foundation lists Anthias Labs as one of its grant recipients for research, and Anthias’ research paper on Liquidity Providers Taking Position of Volatility, available on GitHub, directly examines Balancer pools and Uniswap v3’s concentrated liquidity model. This is not theoretical work. Practical, data-grounded research that the Uniswap ecosystem uses internally.
When a developer reads that paper and sees Anthias as the author, that developer has just been marketed to. No ad, no banner, no pop-up. Just a 12-page PDF that makes the reader smarter.
The pattern: build what your clients already need
Most Web3 teams approach marketing as a separate function. You hire someone to write tweets, someone else to run Discord, and someone else to manage your Galxe campaigns. The marketing function sits apart from the product function.
Anthias Labs reveals a different model. The tools they open-source (simulation frameworks, CLI tools, LP models) are the same tools they built to service their advisory clients. When Aave needed help with risk parameterisation, Anthias built the simulation infrastructure. When Uniswap Foundation needed LP research, Anthias wrote the analysis. They open-sourced the byproducts of their paid work, and those byproducts now do the marketing.
As the Anthias Labs GitHub README puts it: “Anthias maintains several open-source public goods aiming to enhance the simulation and modeling infrastructure in the decentralized finance ecosystem.”
“Public goods” is a framing that earns trust. When you open-source a simulation toolkit, you are not saying “hire us.” You are saying “we know what we are doing, and we want the ecosystem to benefit.” The hiring happens downstream, in the mind of the developer who runs the tool.
How this maps to your protocol
Not every protocol needs a Rust EVM simulation framework. But every protocol has internal tooling that could be open-sourced for developer mindshare. The question to ask is: what did your engineering team build in the last six months that other teams in your ecosystem would find useful?
The answers are usually hiding in plain sight. A liquidation monitor you built for internal use. A liquidity depth calculator. A gas optimisation script. A position health dashboard. Anthias has monitoring systems it built for protocol partners that track “individual position health scores, position correlation matrices, protocol bad debt, and collateral at risk of liquidation.” These were built for clients. They open-sourced nothing that was directly client-specific, but the patterns, the frameworks, the way of thinking about risk, those become Arbiter.
You do not need to open-source your competitive advantage. You need to open-source the tools that demonstrate you have one.
The Solana Foundation model
The Solana Foundation grant that funded Flare is a particularly instructive case. The Foundation did not hire Anthias to do marketing for Solana. It funded a developer tool because Solana needed better CLI infrastructure and Anthias had the expertise to build it.
This is the grant-funded open-source model that protocols should study. Instead of sponsoring a hackathon booth or buying a banner at a conference, fund the open-source tools your ecosystem actually needs. The return is not immediate; you will not see it in this month’s DAU numbers. But the developer who hits flare send from their terminal and gets a clean UX is more likely to build on Solana than one who fights with RPC endpoints.
For Anthias, the Solana Foundation logo appearing on its website alongside Aave, Compound, and Euler is an endorsement that no ad campaign can match. A $21.86M advisory firm with no marketing team has a better partner page than most protocols with a full-time comms function.
The numbers count
Anthias Labs manages $21.86M in TVL, all of it on Base, according to DefiLlama. The firm has zero token, zero venture raise, and zero observable fee stream on-chain. It earns its revenue through advisory retainers and project-based consulting.
In a market where most protocols measure success by price action, Anthias is a counter-example. Its growth is purely reputation-driven. A developer runs Arbiter, reads the research, sees the partner logos, and picks up the phone. No ads. No quests. No token.
Over the past 30 days, Anthias’ TVL has declined 13.4% from $25.26M to $21.86M, with a sharp 25% dip on 24 May that recovered within 72 hours. The volatility suggests a single large client position being managed, not customer churn, and the recovery speed speaks to the stickiness that reputation-based business models produce.
What this means for marketing in DeFi
Open-source tooling is a distribution channel that most protocols do not even know they have. It is not a replacement for a marketing strategy, but it reaches an audience no ad campaign can touch.
The typical Web3 marketing budget breakdown (60% on social, 25% on events, 15% on content) allocates almost nothing to developer tooling. Developer tooling has the best retention curve of any marketing channel. A Twitter ad survives three seconds. A GitHub star lasts as long as the repo stays alive. A developer who forks a tool and integrates it into their workflow has been marketed to every time they run it.
Anthias Labs did not set out to build a marketing engine. It set out to solve real problems for real clients, and open-sourced the results. The marketing was a side effect.
The question for your protocol is: what are you building that could have the same side effect?

Frequently asked questions
Why is open-source tooling better for Web3 marketing than traditional ads?
Traditional ads require constant spend to maintain visibility. A GitHub repo, if it solves a real problem, continues attracting developers, forks, and stars without ongoing investment. Open-source tooling also builds credibility: a developer who evaluates your protocol sees the code, audits the quality, and forms a trust signal that no ad can replicate.
How do I know which tools to open-source from my protocol?
Look at what your engineering team built internally to solve a specific problem. Liquidation monitors, token calculators, gas estimators, MEV analysis scripts, position health dashboards, if it solves a developer pain point and does not expose your competitive advantage, it is a candidate. The test: would another team in your ecosystem find this useful?
Does open-source tooling replace a marketing team?
No – it supplements a marketing strategy by adding a distribution channel that most protocols ignore. The protocols that combine open-source tooling with traditional marketing, Uniswap, Aave, Compound, outperform those that do only one or the other.
Can a small protocol afford to maintain open-source tools?
You do not need a dedicated open-source team. The most effective tools are byproducts of paid work. If your engineering team builds a position health dashboard for an advisory client, cleaning it up for open-source release takes days, not months. The maintenance burden is minimal if the tool is already stable.
How does the Solana Foundation grant model work for open-source development?
The Solana Foundation, like several other ecosystem foundations, issues grants to external teams that build infrastructure benefiting the Solana developer experience. Anthias Labs received one of these grants to build Flare. The arrangement gives the Foundation a useful tool and gives the builder a funded project with a credible partner logo.
