  • Tim Berners-Lee: ‘Web3 is not the web at all’
    14 projects | | 4 Nov 2022
    The "app" (Distributed App / DApp) is some arbitrary thing written by a developer, running in a sandbox in a tab in your browser.

    The "wallet" (Metamask) is a browser extension containing a set of pairs of (RPC gateway URI for a given blockchain, cryptographic private key for an account on said blockchain.) It can also proxy through to other such "wallets", e.g. "hardware wallets" (smart cards.)

    "web3" is an API (like any DOM API) that the browser extension exposes to app, allowing the app to ask the wallet to do things (where the wallet then asks the user to confirm that they want to do those things); and, through the wallet's connection to blockchains, to watch for things to happen on a blockchain.

    Together, these additional APIs allow web3 "DApps" to transact on blockchains, and to observe what happens in response to their transactions.

    Example DApps:

    - Gnosis Safe ( — an interface for deploying and managing multi-signature smart contracts (i.e. trusts whose assets are controlled by M-of-N voting)

    - Sushiswap ( — an interface for creating and managing Automated Market Maker liquidity pools

    - OpenSea ( — a marketplace for buying and selling NFTs

    On all of these websites, you'll notice that instead of registering an account, there is a button that CTAs you to "Connect a Wallet." This is requesting permission to communicate with the web3 agent installed as an extension in your browser.

    Approving transactions on your wallet. This is crucial. Approving a transaction on your wallet should not be something you speed through. This is where you can sign away all of your assets if you're interacting with a malicious contract. If you are trying to sell your NFT on OpenSea, it will ask you for approval. Take a look at the photo below. Make sure it says at the top. If you approve this same transaction on a malicious website/contract - you can say goodbye to your NFTs.

    Can there be malicious contracts on the legit site? Does that require opensea to be malicious themselves or can sellers do some dodgy shiz by listing their stuff?

  • DO THIS IF YOUR ACTIONS (listing, cancel listing, buying, etc..) ARE STUCK:
    2 projects | | 21 Oct 2022
    Did you try listing or buying something on and the "waiting for confirmation" would just spin infinitely? Well this happened to me too. I could not cancel or create new listings at all and this went on for two days until I decided to look up what could cause this issue.

    Looks like your last confirmed transaction is from 13 mins ago. Are your actions on still blocked?
