chains VS metamask-extension

VladChernenko posted on Feb 26, 2023

chainId: An integer greater than zero that defines a unique id for your private network. The main network has ID 1. If you supply your own custom network ID which is different than the main network, your nodes will not connect to other nodes and form a private network.. You can find a community-run registry of Ethereum networks at https://chainid.network.

The current ChainID of the PlatON mainnet is 100, which conflicts with that of other networks registered in ethereum-lists/chains. To better support DApps like MetaMask, another ChainID is needed, one that is unique and registered by a unified third-party platform under the EVM framework. As the PlatON mainnet has been running for nearly a year, the existing ecosystem tools (wallets, browsers, etc.) cannot be immediately migrated or adapted to the new ChainID. It is therefore proposed that the PlatON mainnet should support two ChainIDs at the same time for a certain period.

ETH-like-chain - What some call "ethereum" could refer to many different chains. For example ETH is chainId: 1, ETC is chainId: 61 and MATIC is chainId: 137. Here's a list of the 100s of chains Trezor could access.

Ofc it's good to always double-check. But the tool is based on legit open repository: https://github.com/ethereum-lists/chains

a list of which can be found here https://chainid.network/

Make sure your Metamask is on the Binance Smart Chain network and not the Main Ethereum Network. Please verify the chain ID, it must be 56 for Binance. Source: https://chainid.network/

Have an Ethereum wallet, preferably Metamask installed.

A  Metamask Account.

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].
