A place to see for yourself

Why this exists

Providing liquidity changes the tokens you own. Fees, price moves and costs all affect the outcome. Passiko gives you a place to explore those mechanics before drawing a conclusion.

It began as an experiment and is growing around one useful loop: learn an idea, test it with your own assumptions, then inspect a recorded example.

Choose your starting point

• Learn offers short lessons with predictions, explanations and follow-up situations. Hints are part of learning; you do not need to calculate an answer.
• Experiment lets you change prices, ranges and fee assumptions. Each result belongs to the setup you supplied.
• Inspect shows pool and position accounting from a recorded block. Historical cases follow a fixed position through a verified period.

Start from the beginning or open the topic you need. Every example is accessible without completing a course.

The name

Passiko is inspired by ehipassiko, an invitation to come and see. Here, that means making the assumptions visible and giving you room to examine the result.

How it is made

Passiko is an open-source project maintained by Apostolos Provatidis ↗. It runs in your browser, with read-only Ethereum data and no wallet connection. Saved experiments and learning progress stay in this browser unless you export or share them.

Read the methods for the differences between hypothetical models, recorded snapshots and verified historical accounting. The source code ↗ is available under the MIT license.
