Rolling a vault

Fees pile up in a vault and nothing happens to them on their own. Somebody has to call roll(). That call is public: any address, any time, no permission, no minimum.

What one press does

1. 1
   Claims

   Pulls whatever pons is holding in escrow for this coin into the vault.

2. 2
   Caps

   Works out the most it can spend without moving the price more than 3%, and spends only that.

3. 3
   Credits you

   Sets aside 0.5% of the spend under your address.

4. 4
   Splits the rest

   50% into locked liquidity, 40% burns the coin, 10% to the KILN burner.

Getting paid

Your cut is credited, not transferred, so a roll costs the same gas no matter who calls it. Call withdraw() whenever you like — there is no deadline and no expiry. The Holdings page shows everything you are owed across every vault.

Slippage

roll() with no arguments accepts whatever the pool gives. roll(uint256 minCoinOut) reverts if it would buy fewer coins than that. Use the second one if you are rolling a large amount into a thin pool.
