I’m building a Java stack for the x402 protocol. I believe today’s payment systems are unnecessarily broken and overly complex. I really like the idea of a protocol that could simplify this space while remaining truly open and not “owned” by anyone—meaning anyone can use it without needing authorization from the protocol’s creator.

It’s fully open source: https://mogami.tech

I just came across x402 recently and am excited to build upon it. My current project[1] will have a tipping feature and it'd be neat to give people the option to not use fiat.

Coinbase has just unveiled x402, a protocol that resurrects the HTTP 402 status code and enables instant stable-coin payments—no bank account, card, or subscription required. APIs, applications, and AI agents can now autonomously settle or receive micro-payments to buy data, services, or computing power.

To tap into this revolution, I created Mogami: a Java / Spring Boot library that lets you make any URL pay-to-access with a single annotation. → Code & docs: https://github.com/mogami-tech/x402-spring-boot-starter

I developed a trading bot framework named Cassandre https://trading-bot.cassandre.tech/

An open source trading bot framework available as a sprint boot starter https://trading-bot.cassandre.tech/

On: Ask HN: What are you learning?

[straumat]

I'm learning about trading bots. It allows me to learn new things about software développement (réactive streams forum example), mathematics, machine learning and deep learning

I made it as a side project : https://github.com/cassandre-tech/cassandre-trading-bot

And i am writing a guide about what i learned : https://trading-bot.cassandre.tech/

This is incredible - Thanks for sharing. Kudos for using the latest goodies provided in spring-boot.

I had an older version but wasn't using reactive. Definitely, this looks promising.

Thanks a lot for your message :) I'm glad you like it.

was your bot profitable? have you done real trading with it yet?

[straumat → z023bs]

Hello :) Well, my bot in fact allows you to build your own strategy quickly so my bot does not include strategy. I'm starting to build a strategy with my bot and ta4j... using kucoin sandbox right now. For the moment, still learning, not yet profitable :)
