I have read many places in the forum and I have come to conclusion that majority of the forum members do not trust closed source code wallets. I advice my friend to migrate from trust wallet to an open source non custodial wallet. He agreed to do so and I will have to help him do that. But as he left my house, one question rang in my head:
What if as he is coming from closed source non custodial wallet and let's say the guys at the backend knows his seed phrase (if possible). He then imported his seed in a closed source non custodial wallet. The guys who I supposed know his seed phrase from the closed source now steal his bitcoin while it is in the new open source wallet. Is it possible and what will be the role of the closed source non custodial wallet to ensure the security of seeds imported into it.

Do not let anyone knows your seed phrase. Open source or close source wallet can not help against the person that knows your seed phrase because the person can steal your coins.
The benefit of open source wallet is that the public know its source code, unlike close source wallet that its source code is only known to the developers that created the wallet, and vulnerabilities can be included which the public can not know about.

With importing your seed phrase from the close source wallet to a trusted open source wallet, you don't really increase the security of your fund. Create a new wallet, make a transaction and send all the fund to the new wallet.

He then imported his seed in a closed source non custodial wallet. The guys who I supposed know his seed phrase from the closed source now steal his bitcoin while it is in the new open source wallet. Is it possible and what will be the role of the closed source non custodial wallet to ensure the security of seeds imported into it.
When migrating from a closed-source wallet to an open-source one, a user should assume that the information he entered into a wallet got compromised and may be used in the future to get access to funds. What one needs to do to protect their holdings from unauthorized access is set up a new wallet (preferably a well-reviewed non-custodial open-source wallet such as Electrum or Sparrow) or buy a hardware wallet (again, an open-source one such as Foundation Passport) and create a completely new seed phrase with different addresses unknown to a potential attacker. Once you transferred funds to new addresses, the developers of a closed-source wallet or hackers silently exploiting bugs in the said wallet won't be able to extract your seed or move your funds. In other words, opting out of closed-source wallets implies severing all ties with the company developing it by changing sensitive financial information that may be used to steal your money.

Importing 1 privkey/seed in some software is actually not recommended for long-term use. Your friend actually didn't leave the trustwallet completely, s/he still has the keys generated (questionably) from the previous wallet software. The worst risk assumption is that the wallet is actually leaked and has been stalked by the hacker to wait for a large tx of input to be transferred immediately.

What it does, is import your private key and immediatelly sends the funds to a new address within the wallet. So, even if the old key was compromised, after sweeping your funds are in your hands only again. Ofc you can do so manually, too.

The wallet is a software that manages your private keys, so recommending an open source wallet is the best option because there are many people who have reviewed the code and verified that it is safe, so the fact that the wallet is open source is meaningless if there are not enough developers who have reviewed the code.
using an open source wallet is not only about security, but many open source wallets outperform closed source ones in features such as the ability to integrate the Lightning Network, enhanced privacy by connecting to your own node/tor, address control feature, better fee estimation, and cheaper fees option compared to closed source wallets. Most of the closed source wallets are weakly programming and very poor privacy, the only reason to use them is that they support a lot of currency pairs and attractive interfaces.
by swapping your coins from closed source to widely reviewed open source wallet will reduce your risks (Electrum or Sparrow.)
for multi-coins wallet i think the open source option as unstoppable wallet is not ideal so hardware wallets are the best.

In addition to what is discussed here you should not forget that migrating to an open source wallet is not going to provide complete security on its own. There is a lot of other things that need to be done to gain a good degree of security. I'd say at least there are two important steps: First step is to making sure you are actually getting the correct software for installation. This is done through some research and finally by finding the correct public key of the developers and verifying the signature of the wallet binaries you are about to install. Example for Electrum: https://bitcointalk.org/index.php?topic=5240594.0Otherwise if you skip this important step you may lose funds in this step. Second step is to securing the wallet you chose. For example by using it offline (in an airgap computer) as opposed to using it online on the same system you use to surf the internet.

These two steps are the most basic things that we need to pay attention to regarding the security we need in protecting assets. In that first step, I myself admit that I often ask myself questions regarding the process I did in installing the wallet software even though until now it still looks safe. Apart from securing it by using it offline to a certain degree, I also pay attention to the seeds that I save. Regarding wallet security, from the beginning until now I have always paid attention to several important steps in protecting assets. Hopefully the assets are safe and hopefully nothing will happen to what I have done.

I have read many places in the forum and I have come to conclusion that majority of the forum members do not trust closed source code wallets. Yes because they are not controlled by the owner of the wallet alone. But both the creator of the wallet and owner of the wallet. That means the both parties have access to coins. And that is just like a Fiat banks which the cashier in the back can also have an access to your account if they have your public bank address. That is the second option of the non custodian or open source wallet is always recommended. I advice my friend to migrate from trust wallet to an open source non custodial wallet. He agreed to do so and I will have to help him do that. But as he left my house, one question rang in my head: Trust Wallet is not trusted at all. So it is better you move out the coins very fast before bit is too late. You should not have second thought if it is for long term investment. What if as he is coming from closed source non custodial wallet and let's say the guys at the backend knows his seed phrase (if possible). He then imported his seed in a closed source non custodial wallet. The guys who I supposed know his seed phrase from the closed source now steal his bitcoin while it is in the new open source wallet. Is it possible and what will be the role of the closed source non custodial wallet to ensure the security of seeds imported into it.
I thought Close Sources is not non custodian. Custodian = Close Source and Non custodian = Open Source. So I don't know why op said closed source non custodial . Op please restructure the bolded sentence again. I don't understand it. I am a little bit confused of the last paragraph of the op.

Trustwallet is close source and we don't know how exactly it's working. I would always consider the worst-case scenario for any close source wallet and assume that developers have access to the keys, but we can't say that trustwallet developers definitely have control over users wallets. I thought Close Sources is not non custodian. Custodian = Close Source and Non custodian = Open Source. So I don't know why op said
A wallet can be close source and non-custodial. Non-custodial means that users have access to the keys.

If a wallet is closed source it is hard to believe that it is truly a self custody wallet, because you can't be sure how the keys are generated or if they are sent somewhere else across the internet, in a self custody wallet only the owner is supposed to control the keys to their wallet. But if we are to go with the obvious meaning of self custody as the owner of the wallet having their keys and seed phrase, then yes a wallet can be closed source and still be a self custody wallet, for example Trust wallet and Atomic wallet, but it can be argued that a true self custody wallet should be open source.

Oh good... everything is possible with the tech geeks. Thanks alot. , but it can be argued that a true self custody wallet should be open source.
Should I agree with this? Anyways you said "it can be argued". I believe open source concerns about making the codes visible and accessible to every developer. So, this shouldn't determine if a wallet is non custodial or not. It can be open source and still compromised.

When we talk about security, it is sometimes like defensive measures you take to increase your protection against different types of attack hence increasing your security. For example when you use a non-custodial wallet you eliminate certain ways you could lose your money and bring yourself one step to being safe. When you use an open source wallet you eliminate other ways of losing your money,... when you use a popular open source wallet you eliminate another set of ways you could lose money, and so on. You may never be able to eliminate every single way you could lose money but that doesn't mean you shouldn't try to eliminate what you can. This is why when it comes to choosing between a closed source wallet and open source wallet the later is always the choice whether or not there is any way that the later could also be compromised.

Import your private key from a closed source wallet to an open source wallet is like you drop your house keys somewhere and can not find them. Your next response is bad, you just order someone to make keys to open your house locks but what if your lost keys found on the street by someone, who will able to enter your house later. You don't know what will happen if you response like this. If you don't want to bet your luckiness with your coins, don't do this. You must move your coins to a new wallet and you have two options. Option one is recommended by hossenimir. Option two is above, sweeping. Sweeping your private keys into Electrum

Of course, because open-source doesn't automatically mean it's secure. It's just that with open-source wallets (assuming a lot of eyes have gone through the source code), potential vulnerabilities could be spotted by coders interested in the said wallet. With closed-source on the other hand, you're entrusting everything to the dev team alone.

Alright, got the technical point right after reading this one. I think this is the very reason blockchain and related resources were made open source in the first place. However soon after people saw investment opportunity and private companies started rolling in with their closed wallets. As charles stated we could never know what is behind the written code. I am always scared to download free apps which are associated with financial operations. There are many apps that could be leading to the phishing operation in the background. In the world of crypto space that’s even dangerous. This is mostly frightening for the newbie since they wouldn’t be understanding the wallets properly. There gotta be way to learn these things for sure.

After reviewing the replies, I believe you have all the technical answers. What I write now is a simple knowledge that most of us forget. it's crucial to remember the following steps to improve security, such as using strong passwords, enabling two-factor authentication, and keeping your devices and software up to date. Do remember that backing up your seed phrase and storing it securely offline is one of the most important steps. If you follow the above steps, you will never be going through any anxiety about losing your cryptocurrency.

I also know that there are some open source projects which many developers are not interested in. This means your code can be open and accessible but due to lack of people's interest in your kind of project, there will not be enough developers to look through the code. In this situation it's even worse because maintaining the code wouldn't be on the shoulders of anyone. For it to be open source and secured, it should be a project that many people have interest in.
