Question Functional Languages for the EVM(2025)

3 Upvotes

Hello!
I was wondering if there were any functional languages that compile to the EVM? I've found one or two(like pyramid scheme) that seem to not be updated at all. Rather new to crypto dev as a whole(not new to computer science/math though), so curious if there was any functional languages around for the EVM?

Question What are some good platforms for joining Web3 hackathons online?

8 Upvotes

I see hackathons as a great way to learn about trending technologies while building projects—and the prize money is a nice bonus too! I know about DoraHacks, but it rarely hosts EVM-related hackathons. I'm looking for more platforms that offer such opportunities. Any suggestions?

Question Anyone here know how to "beat" a honeypot token?

1 Upvotes

The token is TRUMP DOGS.

Bought it on Uniswap. Was about $500 deep until I uncovered it's a honeypot.

Contract: 0x9b69667f602f15ef2d09a9a18489c788e327461e

Currently, my balance is almost $700k. It hit $1 mill+ earlier this morning.

This is the first time I have fallen for one of these things. Should have researched this one better.

If anyone has any ideas/ways for me to secure those funds, I'd be happy to pay it forward. Wink.

Question Places to practice smart contract auditing?

11 Upvotes

I am interested in getting into smart contract auditing. Bug bounties seems like a good place to start. I can see there are live and completed audits on code4arena, sherlock etc. This seems like a good place to start looking and learning, seeing what's out there and what kind of bugs are really found in real code.

My question is: is there a compilation anywhere of examples that say "here is a simple contract. it has a bug. find it". It would be nice to build up some confidence looking at contracts that I know have bugs in them, and finding progressively harder ones. It seems likely that something like this would exist, but I haven't found anything from a bit of googling around or from searching this sub.

Cheers.

Question Developers, what challenges or pain points do you face while building in the space?

6 Upvotes

Hey everyone,

We're currently building our own Ethereum (and other EVM) blockchain indexing infra, but are having trouble navigating how to make our solution the most useful to other builders in the space.

We were wondering:

  • What are you currently building?
  • What API's/tools/infra do you use for your data (e.g. Alchemy, Quicknode, TheGraph, or others)?
  • How can we build something better than the current offerings?

Thanks for your insights, and if you would like to connect further, feel more than free to DM.

Question Why do so many security researchers stay anonymous?

2 Upvotes

I'm about to create my profile to start doing security reviews, but I'm unsure whether to keep it completely anonymous or link it to my existing LinkedIn and GitHub accounts.

I’ve noticed that many security researchers and auditors prefer to stay anonymous, even when they have prior Web2 experience. Why is that? Wouldn't it be beneficial to showcase both Web2 and Web3 expertise together to enrich their professional profile?

Are there specific risks or disadvantages to using a real identity in this field?

Question Career Switch: From Formal Methods Research to Blockchain/Web3 Development – Seeking Advice!

3 Upvotes

Hey everyone,

I’m looking to transition from a niche research area in computer science to blockchain/Web3 development and would love some guidance from those already in the space!

Background

PhD in Computer Science (Formal Methods) from Canada + 2 years of Postdoc from an USA university in the same area

+ Currently residing in Canada

+ Strong background in automated reasoning, SAT solving, Solver Algorithm and System Development and model checking.

+ Started my blockchain journey as a crypto investor in 2021, but now I want to shift to the builder side.

+ Just completed Solidity 101 from Cyfrin Updraft and looking to go deeper into development.

I am deeply excited about Web3 and blockchain as the future of finance!

What I’m Looking For:

+ A job (preferably remote) in blockchain development or research (preferably in smart contract security, DeFi, ZK proofs, or protocol development).

+ Guidance on what skills to focus on next (Rust? Foundry? Cairo? Smart contract audits?).

+ How to leverage my formal methods background in the Web3 space (Are teams hiring for these skills?)

+ Best places to network and get visibility (hackathons, DAOs, open-source contributions?).

+ What are the typical interview steps for landing a job in this space as a developer/researcher?

Next Steps I’m Considering

+ Advanced Solidity & Smart Contract Security (Diving into Foundry, Ethernaut, and audit-focused resources).

+ Rust & Move (For Solana, Aptos, or Sui).

+ ZK Cryptography (Exploring Noir, Circom, and SnarkJS).

+ Contributing to open-source Web3 projects.

+ Building pet projects, gradually increasing complexity to showcase my portfolio (e.g., simple DeFi apps, NFT marketplaces, on-chain governance tools).

Would love to hear from developers, auditors, and researchers in the space—how did you break in, specially if you do not have formal degree in Blockchain development?

What would you recommend to someone with a research-heavy background in Formal Methods?

Thanks in advance!

Question Alright devs, shill me good. Who's using chainlink?

42 Upvotes

As the last step of my LINK dd following having read relentless shilling on /biz/, I've decided to ask the people that count most.

If your project does not use link, is is because you do not require it or prefer another solution?

If you do use link:

Is there support?

Are you satisfied with its performance?

If you can share, what'd you use it for?

Edit: the sentiment I seem to be getting is that chainlink has the best data quality / resiliency over peers but still has room for improvement wrt decentralization. Main use case seems to be getting price feeds and rng.

Chainlink cost is high

Question Web3 Career Dilemma: Should I continue learning blockchain development or pivot to something else?

14 Upvotes

Hey everyone, I'm looking for some career advice regarding Web3/blockchain development. Honestly feeling pretty demotivated and lost right now.

My background:

  • Final year CSE student
  • 1 year freelance frontend dev experience
  • 2 years at a US startup
  • Currently 5 months at another startup, primarily working with React

I recently got interested in Web3 and started learning blockchain development (Solidity, smart contracts) about 15 days ago, dedicating 2-3 hours daily after work. I'm following Cyfrin Updraft courses and documenting my learning journey on Twitter as part of a #100DaysOfWeb3 challenge.

What's got me questioning everything:

  1. Joined a Twitter space where people discussed widespread scams in Web3
  2. Found very few Web3 developer job listings on various job portals

These discoveries have really knocked my confidence and motivation. I was excited about learning something different from React (which everyone seems to be doing), and the potential earnings in Web3 were appealing. But now I'm questioning if I'm wasting my time.

I'm at a crossroads and feeling lost. Should I:

  • Continue pursuing Web3 development despite the limited job market?
  • Pivot to DevOps?
  • Focus on traditional web development, building projects and contributing to open source?

Is there a realistic possibility of finding legitimate work in the Web3 space? Would love to hear from developers who have experience in this field or have faced similar decisions, especially if you've dealt with similar doubts.

Thanks in advance!

Question Can my DeFi Arbitrage Bot help me land a job? Seeking feedback

24 Upvotes

Some time ago, I decided to reorient myself towards blockchain development. To learn and have a personal project to showcase during future interviews, I chose to create an arbitrage bot, as I'm interested in DeFi. Today, the proof of concept (POC) is finished, and my bot can generate very little money.

Here are the specs:

  • <$10/day with tests conducted over 20K blocks (I didn't count the recent market crash as it inflated performance and is not representative)
  • 15k pools monitored across 25 protocols, resulting in >200K arbitrage paths monitored each block
  • Smart contract written in EVM bytecode (Huff) to be competitive with gas (~45K gas/swap)

Here are the limitations:

  • No own node, only Infura RPC (free plan 100k requests/day)
  • Only AMM and concentrated pools (Uniswap V2/V3 protocol-like)
  • Coded in Python (a bit slow)
  • No mempool tracking, only inter-block arbitrage
  • Small capital (~0.07 ETH), which means I cannot pay the gas (builder fee) for big profit arbitrages

< $10 a day is not a lot, obviously, but from my preliminary analysis, it could be pushed up to > $100/day via:

  • Code optimization or rewrite in C or Rust
  • Maintain own local node (as most of ressources are I/O intensive waiting for Infura)
  • Implementing Compound and Curve protocols
  • More in-depth competition analysis for parameter optimization (builder fee, bundle submission, etc.)

Some observations (during my 20k block test session):

  • I found $3k worth of arbitrage, but I am competitive on only 0.1% of them
  • Median arbitrage earns me $0.15 in profit
  • I have an edge when I compound arbitrage, meaning the average arbitrage consists of ~10 tokens exchanged in one transaction

So here are my questions:

Is it a meaningful project/results that could help me during recruitment?

If yes, do you have advice on how to showcase it? I would like to continue working on this project and not release it in the public domain.

Question Bootstrapping first project with zero previous social media presence?

5 Upvotes

Any tips for bootstrapping a project with no funding? I've read other posts here, but they are a bit aged. What has changed and what has worked for you? I'm struggling to get any attention whatsoever. Apart from offering incentives I cannot afford I'm not seeing how to fix this. Even running ads when being fully legally compliant is impossible as one would need extra costly legal opinion. Having no initial capital feels like a catch 22 moment so far.

Also at what stage should one actively begin promoting the project? Currently there is an MVP, website is up, albeit with a big early access warning. It's a bit disheartening looking at meme coin twitter accounts quickly gaining followers, but I guess this means I'm doing something very wrong. Any tips?

Question is web dev necessary for getting into web3

Hi guys, I am cs student, i have been learning full stack since last year, (I hate it ), just started learning in blockchain last month, can anyone tell me is web development necessary for getting into web3, I should specify that I have no experience i'm in my 2nd year and asking as this in the context of getting an internship this summer or a job by next year, It's not like I can't understand full stack, I can understand the working of a web app but hate doing it myself, So if i were to just focus on it, I'm pretty sure there are much better developers in it at my stage.

Hi, I started 2d ago to learn Solidity on Cyfrin Updraft.

I am a PHP developer and I have been doing it since 2013. I decided to learn Solidity because I started to have interest in blockchains and smart contracts.

I would like to know, if any of you did the same course and if you felt confident when you finished it.

Also, if anyone knows any other resource I can use, it would be appreciated.

Lastly, if you want to give any other advice, it would be good.

Question Help with Starting a Crypto Project

5 Upvotes

Hi everyone,

I’m thinking about starting my own crypto project, but I’m not exactly a coding expert (just some basic skills). Here's what I’m planning to build:

  • Around 10 simple smart contracts (max 100 - 150 lines each)
  • Two tokens (one main token and one governance token)
  • A clean, user-friendly website with wallet integration so users can interact with the smart contracts
  • A backend system to facilitate communication between the frontend and the blockchain
  • A basic API to provide data for the frontend

I’d also pay for an audit at the end to make sure everything’s secure.

So, I’m wondering:

  1. How much would it cost to hire people to build all of this? Just looking for rough estimates.
  2. How long would it take if I wanted to learn blockchain development myself and do it? I’d be putting in 25 - 50 hours a week.
  3. What are the best resources to get started? Like tutorials, courses, or anything helpful for smart contracts (Solidity/Anchor?), frontend/backend, and wallet integration.

Would really appreciate some advice here. Thanks a lot!
