Yesterday, we finished first place in the @base track at @MBC_Conference with our project BaseLens! I'd like to give a huge thanks to: @Evanzsolomon @college_xyz @coinbase It was my first time in the US, an incredible experience. Feel free to reach me, DM open. Thread ↓

Back to back @ETHGlobal 🥸 May - Open Agents: 1 of 7 finalists, 468 projects, solo. Today - ETHOnline: 1 of 8 finalists, 814 projects, 1,462 hackers, 89 countries, with @Robe_Mule. And @UniswapFDN's Best Uniswap Stack Contribution. TARE measures what a @Uniswap v4 hook really takes from your swap. You pick the route on a @Ledger, with what each hook takes on screen, and only then does @MetaMask open. Rates are attested on @hedera. So you see what a hook takes, three seconds before you sign. 🔗 tare-hooks.tech Thanks @42Blockchain_, @42Network, @42born2code, @42Perpignan

You sign a swap. The hook takes its cut. Nobody shows you the number. TARE does. Our @ETHGlobal #ETHOnline project, built for @42Blockchain_ with @Robe_Mule. Same association, same obsession: ship Web3 from @42born2code . Round 1 async judging: cleared. Round 2 live judging today, let's go. ▶️ tare-hooks.tech

Proud to share the result of this project, started 2 months ago after we identified a real demand for Web3 courses within 42. I built the platform from scratch and co-hosted the launch event with our president @Robe_Mule. Huge thanks to @Kr4t0s4s who framed the pedagogy of the path. 🙌 Big thanks to @Ledger and @AntoineM_eth for the trust and support. 🔥 👉 elearning-42bc.xyz Since launch on Friday June 19th, we're already at 100+ signups, first feedback already coming in. The goal: make it THE reference for learning Web3, aiming for hackathons !!! 🎁 The Ledger contest is live: ship your build, help us grow the platform, and walk away with a Ledger device. #Web3 #blockchain #Ledger

#LedgerSponsor Built GuardLens on @Ledger's Agent Stack 🔐 for @42Blockchain_ An AI agent turns plain English into an Ethereum tx, but it holds no key. A policy engine vets it; only the Ledger device can sign. Agent proposes, device confirms and the tx lands on-chain. DMK + Speculos 👇 github.com/JeanBaptisteDuran… #Sponsored

First @ETHGlobal hackathon. Straight to Open Agents finals. Solo dev for @42Blockchain_ 1 of 7 finalists, out of 468 projects, 750 hackers across 72 countries. LPLens is an autonomous agent on @0G_labs that diagnoses why your @Uniswap LP position is bleeding, replays the last 1 000 mainnet swaps swap-by-swap through every V4 hook to find the winner, then migrates you in a single Permit2 signature. What makes it different: - ERC-7857 iNFT on 0G Chain, agent's memory + reputation update on every run, intelligence verifiably embedded - Per-position @ensdomains records under lplensagent.eth, queryable by any other agent - 6 MCP tools, 3 gated by on-chain mintLicense (0.1 OG / 24h, 80/20 royalty), 3 free verifiers - 5 independent paths to verify every signed report. Same hash, five sources. No LPLens server in the trust path. Try it: lplens.xyz Huge thanks @0G_labs @UniswapFND @ensdomains @ETHGlobal and Kartik for running an unreal finale. #ETHGlobal #OpenAgents

New cohort. New builders. Same obsession. 42's next Web3 wave is on the way, and they're built different. Keep your eyes open 👀 Thanks to our president @Robe_Mule for presenting @42Blockchain_ to all the newcomers at @42born2code 🫡

Finished first at the @SharkPoolSol Season 2 competition @42Blockchain_ took the club win with 50+ members competing GG to everyone who battled on the leaderboard #SharkPool #Solana

What a day at @signalweek 2026 Carrousel du Louvre. 10,000+ people from finance, crypto and policy all in one room From building at #HackTheBlock this weekend to attending the main conference today, this week has been unreal @42Blockchain_ #ParisBlockchainWeek #PBW2026

Incubation program by @SharkPoolSol this is how you build the next wave of Solana builders. @42Blockchain_ staying close to this

Why @solana leads? Simple - thousands of TPS, near-zero fees, and a builder ecosystem that never stops shipping. From DeFi to education with @SharkPoolSol, everything moves faster on Solana #Solana #Web3 #SOL

Last week of @SharkPoolSol Season 2 and @42Blockchain_ is fighting for the top 🦈 What makes SharkPool different? They actually back university blockchain clubs, delegating stake to student-run validators and connecting campus builders across 15+ universities on @solana. #SharkPool #Solana #Web3

Presenting CorLens - what the @42Blockchain_ team built in 36h at #HackTheBlock 2026 XRPL has 2,400+ fiat-to-fiat corridors. Nobody mapped them. Until now. CorLens is 2 things: Corridor Atlas - the first public map of every fiat-to-fiat corridor on XRPL with real-time liquidity and health status Safe Path Agent - an AI agent that finds the safest route for any currency pair and flags on-chain risks nobody else catches, thanks to inner tools like our entity audit Second place on the Data Visualisation track.
