papertax launchpad and $TAX — Status and design notes for the papertax token launchpad and the $TAX token. Both are paused: nothing is deployed (not even on testnet), and there is nothing to launch, stake, claim or buy. Use this to answer questions about the pause or how the launchpad was designed (pool fee split, $TAX allocation). Official news comes only from X @papertaxdev. With an address, also returns that wallet's current PAPER stake on papertrade (public on-chain data); this says nothing about any future airdrop.

papertrade positions and what they keep — Free, read-only. A wallet's papertrade (BTC and ETH perps on HyperEVM) balance and open positions: market, side, leverage, margin, entry, current price, liquidation price and how far away it is, and what each would keep if closed now, after papertrade's impact haircut and 2% win fee. Answers "how are my positions doing?". Closing or opening needs the wallet's signature on papertax.xyz.
Added "buy_report"; changed the definition of "create_verified_pnl", "explain_tax_treatment", "export_tax_file" and 3 more (7 tools before, 8 now)

What a wallet kept on papertrade — Free, read-only. What a wallet kept from papertrade closes over a period (default the last 30 days): closes, wins, losses, liquidations, win fees paid, PAPER minted, by market, and the best and worst trade. Answers "what did I keep this month?".
Top papertrade traders — Free, read-only. papertrade's top traders by profit and loss over 24h, 7d, 30d or all time, or a search by leaderboard name or wallet, with the X account a trader signed in with, if any, and a link to their page on papertax.xyz/traders, where people can follow them. Not recommendations.
What closing a papertrade position would do — Free, read-only. What closing one papertrade position (or all of them) would keep at the current price or a price you give, and what that does to the wallet's realised net for a tax year (all venues, and papertrade alone). Answers "what would closing my ETH long do to my tax year?". An estimate, not tax advice; nothing is closed.
papertax's default treatment notes for Australia, the US, the UK, Canadaor, New Zealand, Japan or Spain, optionally for one event type. Not tax advice.
