Optics — how it works
White light in.
Every colour out.
White light goes into a prism as one beam and comes out as every colour at once. A beam here does the same with ETH: everyone who is in before the split comes out at the same price.
Cast
01One transaction creates the whole supply, opens the token's ETH pool on Uniswap v4 with the facet as its hook, and mints the pool's liquidity as a Uniswap position NFT straight to the dark address. The NFT is burned the moment it exists.
The caster chooses how long the beam gathers: anything from no window at all up to an hour. Nothing else is up to anyone; every other term is a constant in verified source.
Gather
02While the window is open the pool is visible and shut. No swap of any shape lands on it, through any router, so there is no launch block to snipe and nobody gets in a second before anybody else.
Instead, anyone can shine ETH into the beam, as often as they like. It waits in the prism; nobody has bought anything yet.
Split
03When the window closes, anyone may split the beam. The prism pushes every wei gathered through the pool as one single swap. One swap means one price: whoever shone first or last, large or small, bought at exactly the same rate.
From that second the pool is open to everyone, for good. Nothing in the contracts can shut it again.
Claim
04Each wallet that shone claims its share of what the swap bought, in proportion to what it put in. If the beam gathered more ETH than the pool had room for, the part that could not be spent comes back in the same proportion.
A beam cast with no window skips all of this and simply opens.
Glare
05Every swap pays a small share of its ETH side to the keeper: off the top of a buy, out of the proceeds of a sell. The split's one swap pays it too. The share is a constant in the facet's source, and the lens carries it over after every trade.
What can never happen
No owner, no admin, no setter, no pause, no upgrade. There is nobody who can change a term or stop a trade.
The position NFT sits at the dark address. Nothing can move it, and the facet refuses every attempt to remove liquidity from any pool anyway.
Once a beam is split it stays open. The gate only ever closes once, at the cast, and only ever opens once, at the split.
The token is a plain ERC-20 with permit: no mint, no burn, no blocklist, no transfer tax. It carries its own picture, line and link so wallets and explorers can read them off it.
