Start with one learning exercise
DexLadder is for learning crypto market mechanics with virtual money. Pick one
question, change one input, and inspect what happens:
- How does risk change position size? Open the
position size calculator.
Keep the account and risk percentage fixed, then move the stop farther from
the entry. Compare the units and position value. The calculation is a model;
fees, slippage and gaps can increase a real loss.
- What changes when I choose a limit order? Open the
paper-trading terminal, compare Market
and Limit, and inspect the limit-price field before submitting anything.
A limit sets a price boundary; it does not guarantee a fill.
- What does a hash demonstrate? Open the
Academy, choose Fingerprints (hashing),
and edit one character. The lesson uses an illustrative hash to show the
idea; it is not a SHA-256 implementation.
No real-money order is placed by these exercises. For more worked explanations,
start with the trading guides.
The gateway to Web 3.0.
The whole on-chain market — every pool, every chain, every venue — opened in
your browser from a single HTML file. Read any DEX pool with contract security
attached, run the real AMM arithmetic, watch liquidations stream live, fork a
chain and trade your own contracts, and put your own bot in front of it.
Nothing here asks for a wallet connection, a seed phrase, an account, or a
deposit. That is the point: Web3 is worth understanding before it is worth
risking, so every ticket on the desk settles in test funds while every number
on the screen is real and live. No telemetry, no analytics, no tracker — your
positions and your history never leave the browser.
Try it in 10 seconds
→ dexladder.com — the live app. No signup, no wallet, no email. It opens straight into the markets screen.
Or take it with you:
1. Download the single HTML file from Releases (or build it — see below).
2. Double-click it.
3. That's the whole install.
One file. 5,449,494 bytes. No bundler output, no module loader, no npm dependency, no build step required to run it, and no DexLadder server anywhere — there is no backend to call home to. It works offline — on a plane, in a lecture hall, on a laptop that has never met this repo. Your desk lives in two stores on your own machine: a localStorage working set, and an append-only IndexedDB archive (dexladder-vault) that keeps the full history of fills, journal entries, alerts and the equity curve past the limits a single browser key can hold. Both leave together, as one signed and SHA-256-checksummed bundle you carry to another machine yourself.
The promise
Most crypto apps are a funnel. This one has nowhere to funnel you to.
- No accounts. There is no login screen, because there is no user table.
- No server. There is no backend that holds your data, because there is no backend.
- No ads, no affiliate links, no referral codes, no token, no upsell.
- No real money, ever. You cannot deposit. There is no deposit.
- Your data never leaves your device. Portfolio, lesson progress and trade history live in your browser — the working desk in
localStorage, the full history in the dexladder-vault IndexedDB archive — and are sent nowhere. You do not have to take that on trust: open the console on dexladder.com and run await DLVAULT.ready; DLVAULT.writable(), then DLVAULT.stats(). No network call is made, because there is nothing to call.
- No telemetry, no analytics, no tracker, no fingerprinting. Nothing measures you.
One honest caveat, stated plainly rather than buried: live prices come from public market APIs (CoinGecko, Binance, OKX, CryptoCompare, Coinpaprika, Blockstream and a few others), so those providers see your IP the same way any website you open does. The optional TradingView chart and the embedded video lessons load from their own hosts when — and only when — you open them. Turn the network off and the desks, the academy and your portfolio all keep working.
Every crypto app wants your money. This one won't take it.
Don't trust — verify. (Instructions for exactly that are below.)
What's actually in it
A sovereign Web3 terminal: DEX pool screening with contract security, AMM
and liquidity mechanics, perpetuals with a live liquidation tape, a bar-by-bar
backtester, a runtime that executes your bot code, prediction markets, and a
local chain fork you can point at your own contracts — with the course built in
and test funds in every ticket, so the only thing you can lose is a
misconception.
