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

@pulsepay/adapter-ccip

Read-only CCIP route checks, live fee quotes, unsigned token transfer preparation, and message monitoring for PulsePay testnets.

Configure chainId and rpcUrl (or inject publicClient). The built-in router map covers Ethereum Sepolia, Hedera Testnet, and Arbitrum Sepolia. Another source requires an explicit router. The RPC must match the source chain.

  • checkLane(selector) checks the RPC chain and router lane, returning the active on-ramp.
  • quoteBridgeFee(params) checks the source token's registered pool, remote-chain support and destination token mapping before requesting the router fee. Amounts use raw bigint token units. Selectors use bigint in TypeScript and decimal strings in JSON.
  • buildBridgeTransactions(params) returns unsigned approvalTx, optional feeApprovalTx, and send calldata/value. Confirm approvals before sending, estimate source gas in the wallet, and refresh fees immediately before submission. Tokens requiring allowance reset need a zero approval first when an existing allowance is nonzero. Pool rate limits, balances, recipient association, and execution-time policies can still reject a transfer.
  • CCIPMessageMonitor.getStatus(messageId) looks up a real bytes32 ID using the public Chainlink API. NOT_INDEXED means pending indexer visibility, not success.
  • CCIPMessageMonitor.waitForDelivery(messageId, options) polls until SUCCESS or FAILED; it supports cancellation, a timeout and a polling interval. Outages throw errors. The core SDK exposes both through bridgeOps.

Capture the actual message ID from the source receipt/on-ramp event or CCIP Explorer. An example hash is never delivery evidence. The web app exposes GET /api/bridge/status?messageId=<bytes32> for status lookup.

A bridge transfer funds a destination wallet. Whitechain invoices are paid only through the Whitechain merchant contract. A CCIP source receipt or destination delivery does not mark an invoice paid.

After building, run node scripts/ccip-check.mjs <sourceChainId> <rpcUrl> <destinationChainId> [sourceToken recipient rawAmount] from the repository root for read-only diagnostics. No wallet credentials are needed.
