Binance Triangle Arbitrage
Detect in-market cryptocurrency arbitrage
This app monitors the Binance cryptocurrency exchange in search of triangle arbitrage opportunities. The HUD is the chart displayed above. It is repainted after each calculation cycle to show snapshots of currently detected arbitrage opportunities. To disable the HUD, set HUD.ENABLED to false. Three symbols related by exchange rates are involved in the triangle arbitrage. Percent profit or loss from executing the triangle arbitrage. This includes trading fees specified via EXECUTION.FEE config. All configuration is managed inside the /config directory. To setup your configuration for the first time, duplicate the config.json.example file and remove the ".example" extension. This process must be done before deploying the app for the first time and redone after each major version update where the configuration has changed. -

Crypto Arbitrage
A cryptocurrency arbitrage opportunity calculator
A cryptocurrency arbitrage opportunity calculator and trading bot. Over 800 currencies and 50 markets. In short, it collects JSON from multiple different cryptocurrency markets, goes through the results, and finds the highest and lowest price for each coin. The script will find the highest price (chbtc.com), and lowest price (Bittrex), and divide the two: 51.8/38.23 = ~1.35 (~35% profit margin) and then push these results to the browser. It will also find the next highest market pairs, e.g. chbtc / jubi is the second-highest pair and chbtc/Bittrex the third, jubi/Bittrex the fourth and so on until every possible combination has been computed. Currently you will have to add a market object with the correct settings in the array markets, situated in the settings.js file. I am updating the project every day and this will change soon. You can temporarily stop loading a market from the frontend, or remove the market by deleting the object in settings.js. -

HSD
Handshake Daemon & full node
Handshake is a decentralized, permissionless naming protocol where every peer is validating and in charge of managing the root DNS naming zone with the goal of creating an alternative to existing Certificate Authorities and naming systems. Names on the internet (top level domains, social networking handles, etc.) ultimately rely upon centralized actors with full control over a system that are relied upon to be honest, as they are vulnerable to hacking, censorship, and corruption. Handshake aims to experiment with new ways the internet can be more secure, resilient, and socially useful with a peer-to-peer system validated by the network's participants. Handshake is an experiment that seeks to explore those new ways in which the necessary tools to build a more decentralized internet. Services on the internet have become more centralized beginning in the 1990s, but do not fulfill the original decentralized vision of the internet. -

Jesse
An advanced crypto trading bot written in Python
Jesse is an open-source AI agent framework designed to help developers build and orchestrate intelligent workflows that combine large language models (LLMs) with external tools, automation logic, and real-world actions. It acts as an agent manager where you can define tasks, contexts, and tool integrations so that AI reasoning is reliably connected to deterministic procedures like API calls, data retrieval, and task execution. Jesse emphasizes structured outputs, safety boundaries, and explainable reasoning, helping users design agents that don’t just hallucinate responses but can coordinate steps, validate conditions, and interact with systems predictably. It also includes built-in support for evaluation, logging, and orchestration so developers can monitor, test, and improve agent behavior over time. Because it’s framework-agnostic with respect to model providers, Jesse can work with different LLM backends, giving teams flexibility in cost and capability trade-offs. -
