How to make bitcoin hd wallet in typescript?

Question

I am trying to create HD wallet for bitcoin.

I have developed an Ethereum wallet, but I am having a hard time making a Bitcoin wallet.

In my case, I am developing a server using Golang and Typescript.

Is there a best practice to make a bitcoin wallet using Typescript or Golang?

I'd appreciate it if you could let me know.

Paul Miller has created a number of modern typescript libraries to help with this:

• https://github.com/paulmillr/scure-bip39
• https://github.com/paulmillr/scure-bip32
• https://github.com/paulmillr/micro-btc-signer

I've also created a small gist to help you get started:

https://gist.github.com/aulneau/2f5aad7030e046fb6b557a3871231d72

High level overview:

• we generate a mnemonic from scure-bip39
• convert the mnemonic to a master seed (via same lib)
• use scure-bip32 to create the hd node
• define our paths (in this case, bip84)
• generate nodes with the receive and change paths
• derive children nodes
• get the witness pubkey hash address for each node

Hope this helps!! let me know if you have any questions
