The S&P 500,
for memecoins.
That number is the whole point. It started at 1000 the day we opened. Above it, memecoins are up since. Below it, they are down. Right now 191 coins are in the index, screened from the 500 most traded on Solana.
The line
Every minute we reprice all — coins and write the number down. This is that record — not a back-fill, not a reconstruction. It only knows what it was awake for.
READING THE RECORD…
The wall
Every coin in the index. Tap one for its numbers. There is no editorial hand here — they are in because they passed, and they leave when they stop passing.
Today
The index is equal weighted, so every one of these counts exactly as much as the others. A coin doing +400% moves the number no harder than the one doing +4%.




How a coin gets in
No application, no committee lunch, no relationship with us. Four numbers decide it, and they are the same four numbers for everybody.
- $50Kof liquidityEnough of a pool that a normal-sized order does not move the price on its own.
- $25Ktraded a dayPeople have to actually be buying and selling it, not just holding a dead chart.
- 100holdersSpread across real wallets, not four people and a bot.
- 24holdIt has to survive a day. Most do not.
Staying in is easier than getting in — $25K and $10K. That gap is deliberate: without it a coin sitting on the line would flicker in and out of the index every few minutes. Fail the lower bar 3 checks running and you are out, no appeal.
What we threw out
An index is mostly a list of things you said no to. Here is every reason, counted live.
The big one is usually security — tokenized Tesla, tokenized Nvidia, bridged Zcash. They trade enormous volume and they are not memes, so they do not get a seat. A share certificate in a costume is still a share certificate.
You are the committee
The real S&P 500 is picked by a committee in a room. So is this one — the room is just open. Vote a coin in below. The 3 most-voted get seats when the round closes. No wallet, no signature, one vote each, change it whenever you like.
Opening the ballot…
$M500
The index is free and always will be — it runs on public data and needs no token to work. $M500 is for people who want to own the exchange rather than the coins in it.

There is no contract address yet. When there is one it appears here first. Anything calling itself $M500 before then is somebody taking your money.
