FROM YOUR FIRST TOKEN TO NFTs
Understand what you own.
APE, MANA and SAND connect this lab to NFT and virtual-world ecosystems. They are fungible tokens, not individual NFTs or collection floor prices.

Observe. Decide. Reflect.
Write down your reason for a trade, watch the result, and revisit your assumptions. An instant paper fill does not model gas, slippage, liquidity or real execution.

Live snapshots and a separate scenario
Live crypto uses market prices from the named DEX pools through DEX Screener. Fetch time is when this browser received the response, not the time of the underlying trade. The service may cache or delay prices. Practice scenario uses invented prices in a separate portfolio.
Wrapped assets are distinct
WETH and WBTC are wrapped Ethereum tokens. WSOL is wrapped SOL on Solana. They are not a Coinbase quote or a guarantee of the native asset’s value. Pool and token addresses are shown with each selection.
Refresh and fill rules
Refreshes run every 30 seconds while the page is visible. A failed refresh or a response older than 90 seconds disables trading for affected assets. Review requests a new snapshot; its price expires after 20 seconds. Returning to the page requests fresh data.
Your progress stays here
No account or cloud sync. Anyone sharing this browser can see the portfolio. Clearing browser storage can erase it; keep a backup. Backups and paper trades can be edited and do not prove investment performance.
Simple paper accounting
$100,000 virtual USD per mode. Token quantity and price support eight decimals; cash rounds to cents. Average cost for realized gains. No shorts, leverage, limit orders, fees, gas, spreads, slippage or NFTs. No real transaction is sent. Educational practice, not investment advice.
