Ask HN: Non-techie friendly way to store crypto outside of exchange

After a small amount of Googling I've found that a "self-custody" wallet app could provide enough user friendliness. What are some good wallets that allow exporting the private key? e.g. The Coinbase wallet app provides a recovery phrase to recover the private keys through the app, but what happens when the Coinbase app stops working? Ideally a wallet should provide an option to export the raw key (with all of the consequences of course ...)

You might need multiple self-custody’s wallets depending on what tokens you’re holding.

The Coinbase recovery phrase you mention is a seed phrase that you can enter in any ETH compatible wallet, the seed phrase lets you easily recover all the wallets generated by the phrase. A private key will only recover the singular wallet that it’s connected to.

Good to know, is this based on some standard i.e. can I generate the key-pairs myself based on the seed phrase?

Didn't catch your reply.

With the Ethers.js library it is trivial[1] to generate key-pairs from a mnemonic phrase. You might be interested in vanity address generator [2].

The Brave Wallet GitHub Wiki[3] has a write up with good links for further research.
