What is DexLadder?A private, on-device place to learn crypto and practise trading with paper money — what it is, who it is for, and what it will never do.

Engine

The Advanced Execution EnginePrice impact, slippage tolerance, gas and priority fees, MEV sandwiches and partial fills — how v156 makes a paper trade behave like a real one.Perpetuals, Funding and LiquidationIsolated margin, the maintenance ladder, real funding rates that move your liquidation price, and a post-mortem that explains the liquidation instead of just reporting it.Every Order Type on the DeskMarket to stop-limit, trailing stops, time in force, post-only and reduce-only, OCO brackets that shrink correctly, and TWAP worked in slices.

Desk

P2P Bazaar, Explorer and the Rest of the DeskA tour of the destinations beyond the trading ticket: the P2P Bazaar, the On-Chain Explorer, Markets, Portfolio and the community corners.Rewind: Trading History Bar by BarReal candles replayed one bar at a time, orders that can only fill on the bars that come next, and a verdict that leads with buy-and-hold.The Liquidity Desk: AMMs, LPs and Impermanent LossConstant product, concentrated liquidity and StableSwap implemented as the contracts run them, with divergence loss, LVR, break-even fee APR and a staking bench from the consensus spec.Portfolio, the Journal and Your RecordBalances, fees including gas, the note on every fill, the Monte Carlo fan, a printable tax summary, signed certificates and an auditor that works without the app.The Desks: Reading the Market\u2019s StructurePool Radar, Leverage Weather, Chain Clock, Forecast, Odds, Chain Ladder, Venue Board, Yield, Convert, Baskets, Supply Drift and Era Ledger — pages named after the question, not the asset.

Automation

Bots: Build One, or Bring Your OwnRules as blocks or your own code in a sandbox, an isolated wallet per bot, the kill switch, the log, endpoint telemetry and a backtest that runs off the main thread.

Data

Markets, the Screener and the Data LadderRungs and sectors, one canonical snapshot, keyless sources with health, honest history, and two independent witnesses for a single on-chain pool.The News Desk, Sentiment and AttentionA transport ladder built after every transport died at once, why newest-first is a feature, the attention pulse, and Sentinel alerts written in plain words.

Learn

Paper Trading vs Real DEX TradingWhat a simulator can teach you, where it must stay honest about its limits, and the habits that carry over to a real wallet.Academy & Interactive LabsThe lesson path, the hands-on labs, the daily challenge and the certificate — and how the trading desk sends you back to the right lab.Journey, Quests and the Daily ChallengeLevels, XP for calibration rather than activity, the first-flight quest, the 60-second daily decision, Discover, the Town Square, the Monument and the certificate.

Sovereignty

Sovereignty, the Proof Ledger & On-Device DesignWhy nothing leaves your device, how the SHA-256 proof ledger seals your history, and how to back up, verify and restore it.Security, Privacy and the Trust CenterNo accounts and no keys to steal, an eval-free payload, a strict policy with one deliberate loopback door, and a Trust Center that lists every host the app talks to.

Platform

DeXaI, the On-Device CopilotThe numeric-slot law, the on-device readers it calls before it speaks, why every action needs a tap, and what the model card states.DexLadder Everywhere: Web, Installed, OfflineOne file behind the website, the installed app, the native builds and the offline mode — plus the storage rules that make backups the one thing you must do.Day, Night and the Design SystemTwo appearances and no third axis, seeded from your system once, a 4.5:1 contrast floor the build enforces, and why every illustration is drawn rather than photographed.

Engineering

How DexLadder Is BuiltOne file, no backend, no accounts: the architecture, the public data sources, the typed core and the gates every release has to pass.Fork a Chain: The Local SandboxPoint the terminal at your own anvil or Hardhat node and trade your own contracts in the same ticket — no keys, dry-run writes, and a doctor for the errors a browser cannot explain.

How this blog is written

One post per surface of the product, written against the build that shipped it, revised in place rather than reposted. Every figure quoted in a post is one the app computes — there are no estimates, no predictions and no signals here. Where a post describes a mechanism, the arithmetic behind it is stated on the methodology page.

22 posts, 17,934 words. The same articles read inside the app at /#/blog, where each one carries illustrations drawn in the browser rather than image files.
