eth-gasnow-extention VS metamask-extension

Gas fees are not at 1000 gwei all the time, as some screenshots might suggest. You can see the historic average gas price on gasnow.org

Just noticed https://www.gasnow.org/ now redirects to www.bitcoin.org

Yesterday someone posted about alternatives to gasnow.org since they are calling it quits. The gas estimator service from Blocknative (blocknative.com/gas-estimator) was mentioned.

There are ways to estimate fees in realtime, such as https://mempool.space/ for BTC, https://www.gasnow.org/ for ETH, etc., if you want to go to the bother. But as above you can pick a low-traffic time such as Sunday morning and you'll probably end up with as low a fee as you're going to get.

what's going on with https://www.gasnow.org/ ?

It costs about $5 to move ERC20's currently.

GWEI

https://www.gasnow.org/ lists the estimated cost of different kinds of transactions, including uniswap swaps.

Wait till ‘rapid’ gas fees are below 100 (https://www.gasnow.org/)

Ethereum fees are unpredictable unlike other crypto currencies. check http://www.gasnow.org for the current prices

Plenty of projects are source-available, but not open source, and get tons of issues, and even contributions (https://github.com/MetaMask/metamask-extension off the top of my head)

You can create an attestation based on an existing schema or create your own. Schemas define the format in which attestations will be made, and in this case, we will use the Is Human schema to attest that the owner of a certain address is human. For this example, you only need to connect your Metamask wallet (or any wallet) to Scroll Sepolia, then enter the address you want to attest and click Make attestation. You can choose whether you want the off-chain attestation, i.e., free, obtained only by signing a transaction. Alternatively, you can choose to make it on-chain and pay for the transaction to make it public and connect it to smart contract logic. In this case, you will need to obtain funds in Scroll Sepolia through a Scroll Sepolia Faucet.

For this tutorial you will need Metamask or other wallet of your choice, with Scroll Sepolia funds that you can get from a Sepolia faucet and then bridge them to L2 using the Scroll Sepolia bridge. Alternatively, you can use a Scroll Sepolia Faucet to get funds directly on L2.

16) Open Metamask app. In this instruction we will use Metamask extension for Chrome browser.

> I get a 3-5 sec lag on launch [0] as it prepares the browser to block ads.

uBO is typically ready in a fraction of second, so "3-5 sec" is not normal. In Firefox all extensions sit in the same process, so it's possible another extension is preventing uBO to be ready in a timely manner, this has happened[1].

That’s where the Form xChange open source tool comes in. It gives you the ability to easily create and use feedback forms on Web3. And it’s pretty easy to implement and use. The solution connects to a MetaMask wallet (which users most likely already have) and allows application users to vote anonymously using one or more forms — with each form allowing for multiple questions.
