Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Ledger Hardware Wallet Solana JavaScript bindings.


Are you adding Ledger support to your software wallet?

You may be using this package to communicate with the Solana Nano App.

For a smooth and quick integration:

  • See the developers’ documentation on the Developer Portal and
  • Go on Discord to chat with developer support and the developer community.

Notes

To run speculos-smoke test make sure Speculos running (apdu port 9999 and api rest endpoint http://0.0.0.0:5000) with Solana app installed on it. Then run the command from root workspace:

$ yarn run ts-node packages/hw-app-solana/tests/speculos-smoke.ts

Troubleshooting

If ledger returns error 6808 - enable blind signature in settings (not needed for unit testing).

Parameters

  • transport Transport a transport for sending commands to a device
  • scrambleKey string a scramble key (optional, default "solana_default_scramble_key")

Examples

import Solana from "@ledgerhq/hw-app-solana";
const solana = new Solana(transport);

Parameters
  • path string a BIP32 path
  • display boolean flag to show display (optional, default false)
Examples
solana.getAddress("44'/501'/0'").then(r => r.address)

Returns Promise<{address: Buffer}> an object with the address field

signTransaction

Sign a Solana transaction.

Parameters
  • path string a BIP32 path
  • txBuffer Buffer serialized transaction
Examples
solana.signTransaction("44'/501'/0'", txBuffer).then(r => r.signature)

Returns Promise<{signature: Buffer}> an object with the signature field

signOffchainMessage

Sign a Solana off-chain message.

Parameters
  • path string a BIP32 path
  • msgBuffer Buffer serialized off-chain message
Examples
solana.signOffchainMessage("44'/501'/0'", msgBuffer).then(r => r.signature)

Returns Promise<{signature: Buffer}> an object with the signature field

getAppConfiguration

Get application configuration.

Examples
solana.getAppConfiguration().then(r => r.version)

Returns Promise<AppConfig> application config object
