what is $SUNK

Everything ends
up down here

Shipwrecks, pirate gold, the phone you dropped off the pier, every bag that was "definitely coming back". Sooner or later it all drifts down to the seabed and stays there. Up at the surface everybody's splashing around, chasing the next wave, panic-selling every dip. Down at the bottom it's quiet. Nothing moves, and nothing has to.

$SUNK is a memecoin on Robinhood Chain, launched on Pons, built around the one move almost nobody makes in crypto: staying still. The site comes with its own ocean floor. Sink your $SUNK there and every person who swims back up pays a toll to the ones who stayed down. Every trade made through this site drops a little more to the bottom. And when you want a thrill, there's Last Bubble: a last-diver-standing game where the pot goes to whoever holds their breath longest.

No promises, no roadmap full of partnerships, no team bag. Just a coin, a seabed and a lot of bubbles.

"Everyone wants to be early. Nobody wants to be still."

The Seabed

Sink $SUNK to the seabed and it costs you nothing. Swimming back up costs 10%: eight of those ten points sink straight back down to everyone still on the bottom, and two are burned for good. Anyone can also drop tokens on purpose: half burns, half rains down on holders. No admin key: the 10%, the split and the burn are fixed at deploy, and nobody (not even the owner) can change them or touch what's down there.

Say 1,000,000 sits on the seabed and 100K of it is yours. A paper hand surfaces with 200K: they leave with 180K, 16K sinks back to everyone still down and 4K burns. Your 100K is now about 102K. You held your breath, that's all. Holder income drips in over six hours, so nobody can dive in right before a big exit and grab it.

How your share grows

When you sink $SUNK you get shares of the seabed, not a fixed number of tokens. Every fee and every drop is added to the pile while the number of shares stays the same, so each share is worth a little more $SUNK every time. There's nothing to claim and nothing to restake: when you surface, your shares are simply worth more than when you went down.

Holder income doesn't land all at once. It drips in evenly over six hours, so nobody can dive in a second before a whale surfaces, catch the payout and leave. The people who are actually down there while it arrives are the ones who get it.

fee arrivesfully paid out after 6h

The small print, in plain words

Surfacing works on any part of your stack: take some, leave the rest down. The 10% is charged on what you take out.

The last one out has nobody left to pay, so their fee, plus anything still dripping in, is burned instead.

Dropping gives tokens away on purpose: half are burned, half drip to holders. If nobody is sunk at that moment, all of it burns. The seabed keeps a lifetime tally of how much each wallet has dropped.

Your share can't shrink because of what other people do. Surfacing, dropping and trading by others only add to it. The dollar price of $SUNK is a different story: that moves with the market like any coin.

What staying down pays

A rough estimate. Real results depend on how many people surface.

You earn per week for staying down +80,000 $SUNK and 400,000 $SUNK burned from supply

Buy or sell right here. Trades go through the $SUNK pool on Uniswap v4 using Uniswap's own router, the same pool everyone else trades on. 1% of the $SUNK side is taken inside the same transaction and dropped on The Seabed: half to holders, half burned.

Last Bubble

Round 1 opens by itself the moment $SUNK graduates from the Pons curve. Send down as many divers as you like, each for the round's fixed entry of about $20. You have 6h to dive, then the hatch locks. After that a pop comes every hour, 18 of them: about 10% of the bubbles still down burst at random (always at least one), more as the round nears the end, so every round is over within a day. Popped stakes stay in the pot, so every surviving diver's share keeps growing. Surface whenever you like (except mid-pop) and take 80% of your share; the rest stays for the divers still down. Early, that's a loss. Late, it's profit. Or hold your breath to the end: the last bubble takes the whole pot.

A round, start to finish

An example with 100 divers where nobody surfaces: the hatch stays open for 6h, then one pop every hour. Each pop takes about 10% (always at least one), and the last few take more, so exactly one bubble is left after the final pop. Every round ends on schedule.

Who pops is decided fairly

A pop happens in two steps. First someone requests it, then it's decided by the hash of a block that doesn't exist yet, a couple of blocks later. Nobody, including the owner, can see the outcome when it's requested, and once the hash is locked in it can't be re-rolled.

Surfacing is frozen while a pop is pending, so nobody can peek and bail. If nobody locks a pop in while its block hash is readable, a fixed fallback seed decides it, so it can never be held back.

To be straight about it: block hashes come from the chain's sequencer. Players can't predict them, but it isn't oracle-grade randomness.

Nobody can stall the game

Anyone can trigger a pop, lock it in or settle a finished round, and whoever does it earns a small bounty from the pot (5% of one entry, never more than 1% of the pot). That pays bots to race each other to keep the game moving, so no single wallet decides when pops happen.

Surfacing: while the hatch is open you get back 80% of your entry. After it closes you get 80% of your share of the pot (pot ÷ divers still down), which grows with every pop. The last diver left takes the whole pot, even by surfacing.

If a round ever ends with nobody left, the pot rolls into the next round, and that round's entry must stay within half to double the last one, so it can't be priced so only one wallet can play.

Three contracts,
no back doors

Everything on this site runs on three small contracts on Robinhood Chain. The site only reads them and asks your wallet to sign. It never holds your tokens. The code was reviewed and tested line by line (72 unit tests, plus tests against a copy of mainnet routing real trades through a Pons pool). That's our own testing, not a paid third-party audit.

What the owner can and can't do

All three contracts list the $SUNK creator wallet as their owner.

On The Seabed and the Seabed Tap the owner can't do anything except hand ownership to someone else or give it up. There's no withdraw, no pause, no fee switch, no upgrade. The 10%, the 80/20 split and the six-hour drip are fixed for good.

On Last Bubble the owner opens rounds and sets the entry (about $20 in $SUNK, since there's no price oracle on-chain), and picks a bot that's allowed to do the same. Round 1 opens automatically the moment $SUNK graduates. The owner can't touch the pot, pick who pops or change the rules.

question 01 of 11

Do I have to sink my $SUNK?

No. $SUNK is a normal token: hold it in your wallet, trade it, ignore the seabed completely. Sinking is for people who want a cut of every exit and drop while they hold.

Rock bottom

1,000,000,000 $SUNK, paired with ETH on Robinhood Chain. The whole supply launches on the Pons bonding curve and graduates to Uniswap v4. No free team tokens: the dev buys on the curve like everyone else.

On Pons, $SUNK trades on a bonding curve first. Once enough ETH has gone in, it graduates to a Uniswap v4 pool with its liquidity locked permanently by Pons. That's when the swap box on this site and Last Bubble both switch on.

Getting some takes a minute. Grab any EVM wallet (MetaMask or Rabby), bridge a little ETH to Robinhood Chain, buy $SUNK on Pons using the contract address here, then come back and sink it.
