How to install Solana on Windows?

Asked 2022-Apr-01 at 07:50

I ran:

curl https://release.solana.com/v1.8.3/solana-install-init-x86_64-pc-windows-msvc.exe --output C:\solana-install-tmp\solana-install-init.exe --create-dirs

In my Windows command prompt and it showed up like this:

It seemed like it installed - so then I did solana --version and this is what happened:

'solana' is not recognized as an internal or external command, operable program or batch file.

I ran solana --version in Powershell, Git Bash, VS Code Terminal, and Command Prompt and it gives the same output.

How do I install Solana?

Thank you!

QUESTION

How can I validate a Solana wallet address with web3js?

Asked 2022-Mar-30 at 08:18

I'm trying to validate that the input text I get from a user is a valid Solana address.

According to the web3.js documentation, the method .isOnCurve() does that:

I've managed to make it work with this code:

...

ANSWER

Answered 2022-Feb-21 at 04:02

To validate a Solana public key may be a wallet address, you should both use isOnCurve() and the PublicKey constructor like you are doing.

The error thrown makes sense. If the address is not a public key, it should not be able to be instantiated.

Perhaps there could be another function made native to @solana/web3.js that takes care of validating wallet addresses for you in the future.

How to transfer (using Program instructions) custom SPL token from my own account to another user's wallet?

Asked 2022-Mar-10 at 16:02

This is my situation:

I have created a wallet

solana-keygen new
I have created my own custom SPL Token

spl-token create-token
Then I created an Account for this SPL Token

spl-token create-account
The SPL token is now in my wallet A

In the Solana Program, I would like to programmatically transfer the custom SPL token from Wallet A to Alice(user) wallet when certain conditions are met (for example, when Alice answered a quiz correctly, she will be awarded some custom SPL token).

How do I authorise the Solana Program to deduct from Wallet A (which I had created) and transfer the tokens to Alice wallet?

Please advise me how to go about doing this. Really appreciate this.

...

ANSWER

Answered 2022-Mar-10 at 16:02

To transfer an SPL token within a program, your best option is to have wallet A owned by a program-derived address, and then your program can transfer the tokens from wallet A based on any logic it wants.

So first, transfer the ownership to your program-derived address:

Get NFTs by CandyMachineId always returning an empty array

ANSWER

Answered 2022-Mar-07 at 08:30

You are probably using the wrong CMID. Find one of your NFTs on solscan and use the first verified creator ID in the metadata as your CMID. (as seen below).

This would explain why the ID also returns an empty array on the magic eden and pentacles sites.

This address is not the same as the CMID in your .cache file.

You need to provide a recentBlockhash in your transaction in order for it to be signed. Most likely, you need to fetch a blockhash and add it before signing the transaction using getLatestBlockhash, ie:

Unable to generate .so file for solana deployment. (No errors)

ANSWER

Answered 2022-Feb-28 at 11:09

.so file are signifies solana files, right?

so stand for shared object, also known as a dynamically relocatable library or dylib in Cargo.toml.

What do we mean by cargo build-bpf?

BPF is a virtual machine inside the kernel, so this should instruct cargo to build for that target.

Is there any reason, why 2021 edition didn't work for the solana example?

I don't know, but I suspect it's a simple fix.

Finally, why does the above command not output my .so file?

Could it be that you are missing the lib section in Cargo.toml:
