Products that do what StarkZap – Gasless Bitcoin Payments SDK for TypeScript does
StarkZap is an open-source TypeScript SDK for adding Bitcoin-backed asset transfers, balances, lending & borrowing and staking to web, mobile, or server apps. The goal is to let developers integrate programmable Bitcoin assets without requiring users to install wallets, manage seed phrases, or hold gas tokens. Under the hood it runs on Starknet and supports WBTC, tBTC, LBTC, SolvBTC, and other Bitcoin-backed ERC20 tokens. ```import { StarkZap, StarkSigner, Amount, fromAddress, getPresets } from "starkzap"; const sdk = new StarkZap({ network: "sepolia" }); const wallet = await…

Bitcoin is hard. Especially for those not familiar with crypto, it is even hard to create a simple bitcoin transaction. bitcoin-sdk-js provides various features which help to create various type of bitcoin transaction so easily, including advanced smart contract like multisig, hashlock, timelock, combination of them, and even your own smart contract. Legacy, Segwit, Taproot features are all suppoted!

Hi everyone! So a couple of weeks ago I was building a chrome extension for crawling data and uploading it somewhere online for further exploration. I found myself struggling a lot with this as I found every solution I tried hard to implement (Firebase, Mongo Atlas, EC2). I mean I only needed a simple endpoint in which I was able to set and get JSON data with some key. In the end I made a small CRUD using Mongo, Sinatra, Puma, and Nginx. Then Chrome complained that my endpoint (raw IP) was not HTTPS so I bought a cheap domain and configured an SSL certificate into my server. I found this to…

Hi HN, I’m Guillaume, the cofounder of Bearer, an Open Source SAST solution. After launching a few weeks ago here on Hacker News with support for Ruby and JavaScript stacks, I’m happy to report we’ve just released a new version (v1.2) with TypeScript support! In terms of code coverage, we use the same rules already implemented for vanilla JavaScript, but as usual, you can build your own. The rules list is here: https://docs.bearer.com/reference/rules/ It’s a first version for TS, but we believe that thanks to the pre-existing JavaScript support it should already…

Hey everyone! We're the folks from Codelitt Incubator. We pay several of our employees either entirely or partially in BTC. This is a huge pain every month when we run payroll. Normally it consists of a wire to Bitstamp (which includes a steep fee), buying the BTC on Bitstamp, sending to our company wallet, collecting receiving addresses, and then paying our employees. Because of this we're building a dead simple BTC Payroll. Our main goal is to make it easy for you to request that your employer pays you in BTC (partially or completely). We don't hold any money nor Bitcoins. It all happens…

Hello HN, I built this because I wanted to give Claude Desktop access to my Notion workspace without running a flaky local Python script via stdio. This is a Node.js/Express implementation of the Model Context Protocol (MCP) that uses SSE (Server-Sent Events) for transport. It’s designed to be stateless and deployable as a container (I'm hosting it on Apify, but it works anywhere with Node). The Stack: TypeScript + Express @modelcontextprotocol/sdk Zod for input validation Bearer Auth for security (since it exposes an HTTP endpoint) Capabilities: It allows the LLM to search pages,…

I built a MCP server using the Typescript SDK that wraps around the JSON RPC methods for EVM Blockchains. Without any extra documentation the LLM is able to interact with the EVM blockchain even through a complex series of requests. To get going, just add the following command to your MCP client of choice (e.g. Cursor) - npx -y ethereum-rpc-mpc [Optional: RPC_URL] It works out of the box with any EVM chain. Example usage with Claude: "What's the ETH balance of 0x742d35Cc6634C0532925a3b844Bc454e4438f44e?" "Is 0x6B175474E89094C44Da98b954EedeAC495271d0F a smart contract?" "Is…
