Locking and rewards

Lock MEME500 for 7, 30 or 90 days and earn more MEME500 from 40% of every ape and redeem fee. Tiers, reward math, early exit and decay.

All docs as text

Lock MEME500, earn more MEME500. Lockers share 40% of every ape and redeem fee on MEME500. That share is aped into MEME500 without a fee and streamed to lockers over 6 hours after each fee distribution, so rewards arrive in the same token you locked and can be locked again. It compounds.

Tiers#

Tier	Lock length	Reward weight	Early exit
Sprint	7 days	1×	Not allowed
Season	30 days	1.5×	Allowed, with a penalty
Diamond	90 days	3×	Allowed, with a penalty

You can claim rewards at any time and extend a lock to a longer tier at any time. The minimum lock is 0.001 MEME500. Locking uses IndexLocker.lock(index, amount, tier); claiming uses claim(lockId), which returns the reward in the second (index token) slot.

Where rewards come from#

From a fee to a locker's claimable MEME500.

Text version

1. Every ape and redeem on MEME500 pays a 0.30% fee.
2. 40% of that fee is set aside for lockers.
3. A keeper apes it into MEME500 with no ape fee (rate limited, with a minimum output).
4. The MEME500 is streamed to lockers over 6 hours, pro rata to each lock's weight. The lockers' 40% of redeem fees is already in MEME500 and joins the same stream.
5. Lockers claim MEME500 at any time.

Reward math#

Your share and APR

weight      = amount locked × tier multiplier (1, 1.5 or 3)
your share  = your weight / total weight of all MEME500 locks
rewards/day = your share × 40% × fee × daily volume      (fee = 0.30%)
APR         = 40% × fee × daily volume × 365 / locked value

The APR formula gives the average for 1× weight. A Diamond lock earns three times the rate of a Sprint lock of the same size, and the total is shared, so more locking means a smaller slice for everyone. Rewards in MEME500 are the USD value divided by the MEME500 price.

Daily MEME500 volume	Yearly locker rewards	APR at $2M locked	APR at $10M locked
$250k	$109,500	5.5%	1.1%
$1M	$438,000	21.9%	4.4%
$2M	$876,000	43.8%	8.8%
$5M	$2,190,000	109.5%	21.9%

Illustrative only. Volume and locked value are assumptions, not forecasts. Nothing is promised.

Early exit#

Penalty

penalty = 20% × time left / lock length      (paid in MEME500)

Sprint (7 day) locks and creator seed locks can never exit early, even after extending.
Season and Diamond locks can. Leaving halfway through costs 10%; leaving on the first day costs close to 20%.
The penalty goes 100% to the lockers who stay, streamed over 7 days so it cannot be captured by opening a lock just before someone leaves.
Rewards or penalties that arrive while nobody is locked go to the treasury.

After a lock ends#

When a lock reaches its end date its weight drops to 1×: anyone can call kick(lockId) to apply it, so an expired Diamond lock no longer earns three times the rate without a commitment. The app shows it as “Matured · 1× until you unlock or relock”. You can unlock, keep earning at 1×, or relock into a new tier.
