Used many machines across Europe and never had to KYC ? Not sure of the benefit of using a Bitcoin ATM if I have need to go through an identity verification process, for me at least.

Is there any purpose designed crypto bank platform? I mean any fiat funds deposited are automatically converted to some ERC20 stable coin? I know you could technically do it on exchanges already like binance. But for any business in high risk industries who struggle dealing with banks, could be an interesting service.

Hi bitmover, thanks for your reply. I'd agree with that, not your private keys not your coins. I've used electrum before, Samoruai is a new one to me - will check it out though.

Ideally yes, Bitcoin, Ether and possibly the capacity for some ERC-20's (DAI etc). If it was just bitcoin though, it would still be okay.

I've been looking into it and I've found Edge (previously Airbitz) - https://github.com/EdgeApp - their wallet app offers milticurrencies and they claim at least to be open source.

I'm not a developer myself, so would have to hire one. I guess my concern was twofold:

1) The ability for a developer to act malicious and somehow put a backdoor in my app? Which seems unlikely if open source software is used?
2) The expense of developing & branding the actual open source within your own app. I'll be adding additional features, but that's the more straight forward part. So I guess it's not too difficult an undertaking in that case - to develop an open source non custodial wallet within your own app?

Technically custodial wallers are not wallets. All wallets should allow users to hold their private keys.  A wallet is an interface that allows you to sign transactions with the private key, just that.

Technically it is simple to use an open source wallet like electrum and modify its code for what you want. There are other good options like Samourai.
Do you want to support more coins? If you do, you can't do that with open source wallets (I don't know a single multicurrency open source wallef)

Hi there,

I am at the concept stage of a project mobile app that I'd like to know the practicality of one part of it.

Basically I would like to use the tech of an open source non-custodial wallet (such as Edge) and build some features ontop of it.

My question is building a non-custodial wallet using existing open source tech, how practical is this? I don't want to build a wallet from scratch if possible due to possible vulnerabilities etc, my budget is'nt big enough to make sure a custodian wallet is 100% air tight. So that's why I had the idea to build upon an existing widely used open source non - custodial wallet.

As it is an open source wallet, would it just be the case of a developer building the user interface around it? Or would there be some security issues also for the holding of the coins etc? I would ideally have the app on andoid and ios.

Thanks in advance
