I’m currently developing a Dapp in React Native expo and I wanted to use MetaMask SDK to connect wallets and use ethers.js to handle transactions.

I found that integrating MetaMask SDK is really buggy and i’ve been running into the same issue and MetaMask support isn’t very helpful with this either. I have been trying to find suitable alternatives but have found nothing.

If anyone has any other options or a solution please could you share.

This is the issue by the way: The package at "node_modules/@metamask/sdk-react/dist/react-native/es/metamask-sdk-react.js" attempted to import the Node standard library module "node:crypto". It failed because the native React runtime does not include the Node standard library.

I’ve found ways to bypass this but its only resulted in my redux Provider not working or its a copout fix and still doesnt initialise the SDK properly.

Hey all,

I created a tool called Whallet to track ethereum wallet: https://www.whallet.app/ . It's still an early preview but I'm planning to add more features as I go.
For now you can add an address to a wallet and check their transactions, their net worth, and when they were last active.
I'm planning on adding support for other chains, better analytics, and better support for transactions (alerting, setting filters, etc...)

I would be happy to receive any feedback :D

Hello, everyone!

I’ve been practicing with smart contracts in Solidity on Ethereum, and I came across a question: is it possible to encrypt data directly within a smart contract?

My goal was to use the blockchain itself to encrypt information using someone else's public key. However, I noticed that Ethereum doesn’t seem to have native support for this.

So, my question is: is there any way to encrypt data within Ethereum using another person's public key, whether with RSA, ECC, or some other approach? Has anything been developed to achieve this?

So I got some great ideas for a game which is going to be very simple and enjoyable with a potential to create a market. I can't code so I am looking for someone who could put my ideas into practice and of course get a big share from the fees the game would make.

I need sepoliaETH for learning blockchain and creating a crowdfunding platform.

Is there any contract-oriented explorer where for example most OpenZeppelin interfaces are integrated? Specifically, I'm looking for a service that supports OpenZeppelin's TimelockController contract — allowing users to view and execute pending transactions while also parsing them to display the underlying (target) contract calls with parameters.

Blockchain explorers aren’t particularly good for contract-specific interactions; they only support basic ABI actions and provide a generic event list. Currently, we use scripts to extract and format pending transactions, but having a UI for this would be much more convenient.

How do you manage contracts like this?

Hey everyone,

I’m looking to stay updated on upcoming blockchain/Web3 hackathons. Are there any good platforms, websites, or communities where I can regularly find hackathon announcements?

Would love to participate, learn, and collaborate with others. If you know of any ongoing or upcoming events, please share!

If you own a project or are currently building one, I would love to connect with you and work on the overall UI/UX and Frontend Development of your Project. I have recently worked with several Crypto Projects on their Websites, Landing Page, Wallets, Browser Extensions and so on.

My core Expertise is in Figma, React, Next.js, Node.js, Python, PHP and more.

I will be looking forward to your messages.

Thank you!

Group of us, international team working on this CEX. Experience crossing blockchain dev, biotech, engineering and potentially having a quantum physicist on board. Top 5 global universities. Can verify all this elsewhere.

We’re about bringing more people on chain while providing an outlet for $3.5trn+ of crypto to be deployed in a useful way.

Already talking to VCs with a white paper being released soon. Had an interest from a big name in the field - won’t name drop, but can verify privately.

Will be US-based but offering remote work.

Looking for serious devs with experience on chain/offchain as an expression of interest.

i started looking for ways to use my eth without converting it, and i’ve been testing out this marketplace called correkt. picked up some home stuff and a keyboard for work, and it felt nice not having to deal with banks for once.

but i’m still figuring out how to make managing crypto income less annoying overall. do you guys have any tools, tips, or platforms you use to make spending or managing crypto income easier?"

Hey everyone! I recently put together a quick tutorial on building a decentralized React app that lets you swap EVM-compatible assets for Bitcoin, all powered by THORChain for seamless cross-chain liquidity. I'm using RadzionKit to provide a solid TypeScript monorepo with reusable components, which really speeds up development.

I’d be thrilled if you checked it out and shared any thoughts or questions. Here’s the video: YouTube

And if you want to dive into the code, it’s all open source: GitHub

Thank you so much for your support, and I hope this project sparks some creative ideas for your own dApp journeys!

Any advice?

I'm using Tenderly to simulate my transactions after one failed when I deployed on ethereum mainnet.

Failed transaction: https://etherscan.io/tx/0xb42b2a9c4f4daa62f58118553af9619c6afd59cf70e9a4cd612f72c77b8e1750
Tenderly (see picture) shows absolutely everything succeeding on the Tether contract right up until my contract reverts the transaction for some reason. This was working perfectly on Sepolia testnet, and it is currently working perfectly on Polygon, but on Ethereum it is failing.

The balance of the sender is high enough, as well as the allowance, as shown by the debug section of tenderly

What else can I do to find out what's causing this error?

Hey guys,

I am a frontend/fullstack developer (but recently more focused on frontend in recent years) and I do have few projects behind me in web3 and I am looking to find some more oportunities for hackathons/collaborations/jobs/clients. I am guessing there are many blockchain devs that need a good frontend dev in their team, but I wasn't able to travel as much to meet people on hackathons in previous few years..

So I was wondering if there is any good online place for this like discord/whatsup groups or something other, better?

I'm going to be launching a utility token on ETH and would like to bridge it to TON and SOL but have not found anythjng suitable.

There will be transaction fees built into the ETH SC, and would ideally like fees to be applicable on the Ton and SOL tokens.

Is any of this currently possible?

Please help me. I need Mumbai Polygon testnet token. If anyone can help me.

Hi all, I'm an artist and I have an NFT project of a collection of 5555 of unique NFTs. Art is 100% done, discord all set up, but need an advisor to advise on what to do next, utilities, which blockchain, and all the etc.

I've read alot but I haven't kept in touch with the news since a couple of days ago.

DM if you think you can help or comment if you think you know someone who could.

P.s: I've already checked fiverr but not really fond of the teams there. Consulting firms are really high priced for me.

Does anyone know how to work vault contracts on arbitrum?

The Problem:
OpenAI, Meta, and Orange recently announced efforts to build AI for African languages. But here’s the catch: Africa has 2,000+ languages, many with little to no digital data. Without datasets, even the best AI models can’t bridge this gap.

What We’re Doing:
We’re a nonprofit team building a blockchain and tokenomics-powered solution to crowdsource, validate, and incentivize the creation of African language datasets. Think decentralized data ownership, community-driven contributions, and equitable AI access.

Who We Are:

A team of 4 founders with 27+ combined years in product development, startups, and AI/data systems.

Backgrounds: AI engineer, Data Engineer, Statistician, Product Engineer, Non-profit and Funding

Committed to impact over profit (nonprofit structure).

We Need You:

- Blockchain/tokenomics expertise (Solana, Polygon, smart contracts, token design).

- Technical enough to lead protocol development.

- Aligned with the mission: Solve the data desert for African languages.

- Comfortable with early-stage uncertainty (we’re pre-funding).

No Fluff:

- This isn’t a “get rich quick” project, it is for the long haul. If you want hype, look elsewhere.

- We’re not here to compete with OpenAI or any other AI war-lord—we’re solving the foundational problem they can’t ignore.

- Remote work, no location preference.

If This Resonates:
DM me with:

- Your experience with blockchain projects

- Why you would like to join us.

- A brief intro about yourself

Let’s build something real.

P.S. Already working on African language datasets, blockchain for social impact, or decentralized AI? Let’s collaborate, not compete.

Hey everybody, i'm doing freecodecamp solidity course and i need some sepolia ETH

(Wallet:0x6576aEC1ddB7068Bc9aE5Be17C7bC79Fe99A99b9)

If will be very useful for me if someone would help or is there a faucet without a minimum balance like alchemy ?

Thanks
