Anti-paper-hands: cooldown and early exit

Every buy starts a cooldown (default 10 minutes, per launch between 1 and 30 minutes). Selling tokens that are still in cooldown adds an early-exit fee (default +3%, between +1% and +5%) on top of the base sell fee (0.50%). After the cooldown the line is cleared: sells pay only the base fee.

The cooldown follows the tokens

Moving tokens to another wallet does not reset the cooldown. HOLD LINE tokens use a Token-2022 transfer hook: every transfer runs the hook program, which moves the remaining cooldown along with the tokens. If wallet A buys, sends to B and B sends to C, C still pays the early-exit fee until the original cooldown ends.

How the accounting works

Each token account has a small holder state with two buckets: tokens you bought (own) and tokens you received (inbound). Each bucket stores an amount and an unlock time. When tokens leave an account, free tokens leave first; locked tokens that move carry their unlock time to the recipient, merged conservatively (the later unlock time wins).

Limits you should know

• Tokens can only be moved while locked to accounts the hook tracks or to protocol venues (the curve and the LINE AMM). This keeps the cooldown from being dropped through an untracked intermediary.
• The first time locked tokens move to a new wallet, the sender pays a small rent deposit for the recipient's holder state (shown in the transaction summary).
• Programs that hold tokens in their own accounts (PDAs) must opt in with a signature to receive locked tokens.

Where early-exit fees go

80% of early-exit fees fund the token's content rewards; 20% go to the protocol. The split is shown in every sell summary before you sign.
