Web3 · sub-niche
MEV protection libraries.
MEV protection + private order flow for DeFi traders + protocols.
Reading the two labels: team-sized build build cost means only makes sense as a team bet, multiple quarters of salary before any revenue, the kind of project incumbents are better positioned to start. Trickle, one deal per quarter deal velocity means few rounds land in this category in a given year, buyers are rare.
Quick take: MEV protection libraries is a team-sized build-cost, trickle, one deal per quarter-velocity opportunity inside Web3, with 3 public reference points. Niche, technical. Fund only with crypto-native team. The moat is the protocol partnerships + the MEV-blocker accuracy.
Why now
MEV extraction is a $500M+/year tax on DeFi. Protection is a real wedge.
What the signal looks like
Repos with private-pool adapters, MEV-blocker libraries, and order-flow auction integrations.
Public examples
We name publicprojects + categories only, never founders we track inside the paid product. The buyer’s edge stays inside the product.
- Flashbots Protect shape
- MEV Blocker
- Open-source MEV-protection libraries
What this displaces
A public-mempool transaction + sandwiched.
How to validate it in an afternoon
Before committing build time or a thesis memo to mev protection libraries, run three cheap checks against public engineering activity. Each takes minutes and none require access to private data.
- Count active builders. Search GitHub for repositories matching this category, then check how many accepted commits in the last 14 days. More than a handful of active teams means the category has energy, not just mentions.
- Look for the trickle, one deal per quarter pattern in funding. If funded companies keep appearing here, few rounds land in this category in a given year, buyers are rare. Cross-check the web3 leaderboard to see whether any of the accelerators sit adjacent to this niche.
- Test the team-sized build cost assumption honestly: only makes sense as a team bet, multiple quarters of salary before any revenue, the kind of project incumbents are better positioned to start. If your calendar cannot absorb that, the opportunity is real but not yours yet.
The weekly signal feed tracks 10 Web3 sub-niches including this one, so the cohort side of this check can run continuously instead of manually.
