Trader Guide

Buy, hold, and sell keys confidently on Twin.fun.

Utility

Holding ≥1 key for a twin unlocks that twin’s gated features in the app (chat, tools, utilities).

Buying Keys

• Call getBuyPriceAfterFee(id, amount) to estimate required ETH.
• Execute buyShares(id, amount) with the exact msg.value returned by the pricing helper.
• The contract does not refund overpayment.

Selling Keys

• Call getSellPriceAfterFee(id, amount) before exiting to preview proceeds.
• Use sellShares(id, amount) to redeem keys for ETH at the lower, post-sale supply.

Reading the Market

• Track supply, last trade price, OHLC candles, top holders, and volume through the subgraph.
• Community dashboards and bots surface analytics powered by the same indexed data.

Risks

• Bonding curve prices move with order flow; liquidity is deterministic but not constant.
• Keys grant access to experiences—they are not traditional financial instruments.
