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 🙏

Readme

@allowkit/agent-wallet

The wallet layer of react-native-x402: signer interfaces, the multichain bridge over the official @x402 packages, and (in development) Nitro-bridged native custody.

@allowkit/agent-wallet/bridge

createOfficialBridge adapts the official x402 client stack to the allowkit PaymentSigner/X402Codec contracts, for both rails:

  • EVM (eip155:*) — EIP-3009 typed-data signing via @x402/evm, from any viem-shaped account (address + signTypedData)
  • Solana (solana:*) — partial-signed transactions with the facilitator as fee payer via @x402/svm, from any @solana/kit TransactionSigner

It also enforces signer-level quote binding: the accepts array is narrowed to exactly the requirement the PolicyGuard approved, and the signed payload is checked against the approved intent before it leaves the wallet.

Invariants

Raw private key bytes never cross the JS boundary. The native custody modules (Secure Enclave / StrongBox P-256, natively-held secp256k1/ed25519, keystore-bound biometric gating) implement the SecureSignerSpec / SoftKeySignerSpec / SecureStoreSpec interfaces exported here and land via Nitro modules.
