TEN NEW DESKS The ten depth desks named in the 1.2 notes ship in this update, each with the same arithmetic as the web build, checked against the same reference figures. Under Portfolio: • Risk: one net delta per asset across spot, perps, pools and options. Historical, normal and Cornish-Fisher VaR, with Kupiec and Christoffersen backtests. Stress scenarios and your book's liquidation level. • Verify: take any figure apart. Inputs, formula, the working, and a second independent implementation. Export as CSV or JSON. • Carry: move your paper desk to another device as a file or QR codes, with optional password encryption. Sign a track record as a proof card anyone can check. Under Academy > Labs: • Path: the order the concepts go in. A concept counts as learned only when you have done it on a live desk, and spaced review tells you what is due. • Replay: every stretch of history that matches the conditions you name, run together as a distribution. Includes a shock and scenario builder. • Order Lab: iceberg, trailing, bracket and pegged orders, and what each costs in queue position, latency, fees and implementation shortfall. • Lending: interest-rate curves, health factors, liquidation calls and cascades, and restaking, on reserve parameters read from Aave v3 at a pinned block. • Options: a volatility surface you can fit and audit, eleven strategies with greeks and payoffs, and what a short option ties up in margin. • Cross-chain: the same trade on six chains. Real tick-by-tick concentrated-liquidity math, L2 fee anatomy, and bridges priced with their failure modes. • Access: measure the app against WCAG 2.2 AA, change text spacing, target size, motion and text size, and switch language (English, Hindi, Spanish, Arabic). Each desk has a Method tab stating which of its numbers are modelled rather than measured. Everything stays on your device. No account, no server, no analytics. All trading is simulated with paper balances against live public prices.

The largest update DexLadder has had. SMART ORDER ROUTING + EXECUTION DESK Quote one order across book-style venues and DEX pools in a single ticket, and see the real difference in fill, price impact, fees, gas and slippage before you route it. Compare, or split the order across venues. DEXSCRIPT Write and run your own strategy logic inside the app, with a built-in editor. CHARTING AT FULL PARITY 133 studies, up from 65. 121 drawing tools, up from 71. TEN NEW DEPTH LAYERS Lending with liquidation cascades and restaking. Options with an SVI volatility surface. Real multi-tick concentrated-liquidity math and cross-chain bridging. Iceberg, trailing, bracket and pegged orders with implementation shortfall. Portfolio risk with VaR backtests. An evidence-gated curriculum. Measured-regime replay and a scenario builder. Device continuity with signed proof cards. WCAG 2.2 AA accessibility and internationalisation. And verify-this-calculation, which shows the working behind any number the app prints. LEARNING 127 reference pages, up from 28. DeXaI now carries 18 tools, up from 10. DEEP LINKS All 168 in-app routes now resolve. Previously none did. CORRECTIONS DCA and grid-bot fills now settle through the real order book with spread and slippage applied, matching what the Trust page and these notes promise. This changes the profit and loss on existing bots and DCA plans. In-app reference text that described the browser build has been corrected to describe this app. Everything stays on your device. No account, no server, no analytics. All trading is simulated with paper balances against live public prices.

Two new desks, and a floor under both of them. THE LIQUIDITY DESK — provide to a Uniswap v2 pair and watch the constant product decide your share; open a v3 position over a price range you choose and see the capital efficiency a narrow band buys you, and the moment it stops earning because the price left your range; add to a Curve StableSwap pool where the invariant holds the peg until it doesn't. Stake, and read the reward curve that pays less per coin as more coins arrive. And impermanent loss stated as arithmetic rather than a warning: what the pool paid you in fees against what simply holding the two coins would have. BOTS — build one from rule blocks and test it on real history before it ever runs: every decision fills at the next bar's open, and the stop is checked against every price inside the bar, wick included. Or bring your own — a JavaScript strategy in a sandbox with the network and storage removed, or your own bot in any language answering one URL per closed bar. Every bot trades its own paper wallet and is ranked by the only number that matters: its edge over simply holding the coin. Everything here is paper money. No account, no wallet, no real funds.
