Apologies if this is a silly question, but I've searched around and have found no obvious way to select an Ethereum testnet while developing an application to support Coinbase Wallet. Am I missing something obvious or is only Mainnet supported? Thanks
This is something I wanted to find out myself and found a solution for both the mobile and the desktop chrome wallet.
on the Desktop Coinbase Wallet you can switch to a testnet with below steps:
Open the settings from the top right
Enable the Developer Mode checkbox
In settings under 'Default Network' you can now find a section with multiple testnets
For the coinbase mobile wallet:
Open Settings in the bottom right
Open Advanced Settins
Switch Network from Mainnet to Testnet
Go back to settings and choose testnet under 'Default Network' setting
In both examples I am referring to the non-custodial wallets from Coinbase, not the managed custodial wallet apps.
You cannot. Most mobile wallets do not support testnets.
For different wallets, check this answer. For mobile wallets supporting testnet, ask help in WalletConnect Discord.

I am trying to make a website that interacts with solana and ethereum blockchain, are there wallets that can handle assets on both of these blockchains and are there any libraries like phantom wallet that supports this
You can do some of your own research, but from a quick search, the following support both Ethereum and Solana:
Exodus
Brave
Torus
There's probably many others! You'll have to try out some and see.
I have already deployed a contract on the ropsten test network and also have the contract address.
But, How do I interact with it through something like an android project?
I know I have to add the dependencies first and all. But, here's the confusion -
I have deployed the contract on etherscan's ropsten testnet through the remix IDE
Deployed a project on infura
Created a metamask wallet which now has 1 eth on the ropsten testnet
now, how do I combine all this such that I can access it in my android studio or any other project for that matter?
All I need is to know how anybody would interact with a contract.
Even getting to know the basic requirements steps would be more than enough.
Any help will be appriciated...
its getting harder and harder to find answers on the net and I don't have much time. Appriciate the help, thank you...
I somehow found a blog with a Github sample project which is simple enough to figure out what does what inside the project.
It is an extremely simple hello world project.
If you are like me and haven't been able to make any progress for the past 4-6 hours because of lack of info, then this will surely help.
here's the Github Link if you are in a hurry.
We recently implemented the webHID API for one of our sites (it is such a godsend) and have the client asking if they can use the devices over a Microsoft RDP connection?
I imagine this would depend on the RDP client and whether they can/do send HID events over the RDP connection.
From some initial research it looks like you can redirect USB over RDP but don't think this will work for us as I couldn't get my device mapping done with the webUSB API.
If anyone has any input on this it would be greatly appreciated.
Thx
WebUSB, WebHID and Web Serial should work with a remoted USB device.
That said, there may be bugs if these devices don't appear to applications like Chrome in quite the same way they do when connected locally. If they don't, it would be interesting to get logs from chrome://device-log and see how the device appears in the Windows Device Manager.
Please file a bug at https://crbug.com/new and let us know so that we can keep track of this issue.
it's my first post here. I would like to ask, what's the possible errors that a developer can face while trying to deploying their smart contract into the Ethereum network.
For example, can it be "Out of gas"? and why does this happen? Could you please let me know or summarize any errors that will prevent them of properly deploying their contracts to the network?
Thank you in advance.
so far so many Dapp developers have made so many Dapps which are integrated with MetaMask or other similar extensions like Parity and Web3.js.
Is there any idea or suggestion about developing one without all those extensions mentioned above ?
Thank you.
There are mostly two reasons these extensions exist:
The user shouldn't need to trust the website to provide their. blockchain data source, and more importantly, users should never have to trust a web app with their account's private key.
Of course you can make sites without those guarantees, but to do that kind of misses the point of decentralizing trust.
I've recently came across a project in alpha: https://fortmatic.com
It gets rid of the need to use DApps without extensions. Docs seems pretty good, was able to get things working pretty fast. It triggers a modal in an iframe for user auth (similar to Stripe or Plaid) - imo this feels like a better ux as the end users never have to leave the main dapp experience
