How Bobber works.
Bobber is a coin on Float that shows you when it is under its waterline and ranks the wallets that buy those dips. Everything below is read from the same files the site runs on.
How it works
Bobber draws one line under $BOBBER: the waterline, its 24 hour average price. The bobber on the home page floats on that line, rides up when the price is over it and goes under when sellers pull it down.
When the price is 3% or more under the waterline, the site says so in plain words. Every buy made in that zone is a catch, and catches rank wallets on the Anglers board.
Bobber shows the dip. It does not buy it for you. There is no treasury, no buyback and nothing to deposit. Holders earn SOL from Float like every Float coin.
The waterline
A small read only bot samples the price every 20 seconds from Jupiter's price API and stores each sample with its time and source. The waterline is the time weighted average of those samples over the last 24 hours, so a quiet hour and a busy hour count the same.
Right after launch there is less than a day of history. Nothing counts as a catch until there is at least 1 hour of samples, which keeps launch snipers off the board. After that the waterline uses whatever window exists until a full day is there.
The rules
These values are read straight from the config file the bot and the site share, so this table always matches what runs.
| Rule | Value | Meaning |
|---|---|---|
| WATERLINE_WINDOW | 24h | The waterline is the time weighted average of price samples over this trailing window. |
| MIN_HISTORY | 1h | No buy counts as a catch until at least this much price history exists, which keeps launch snipers off the board. |
| UNDER_THE_LINE | 3% | A buy is a catch when the price is at least this far under the waterline at the moment of the trade. |
| SAMPLE_EVERY | 20s | How often the price is sampled and new trades are read from chain. |
How a trade is read
- Every transaction that touches $BOBBER comes from Helius parsed transactions.
- The trader's coin and SOL changes decide the side and the price. Liquidity moves and transfers are skipped.
- A trade priced more than 2x away from Jupiter's price at that moment is treated as a market maker leg and left out.
- The waterline at the moment of the trade is stored next to it, so every catch shows how far under the line it was.
Where the fees go
Bobber uses Float's standard split and adds nothing on top. The 5% creator share goes to the creator's wallet. The holder share goes to holders in SOL. The rest goes to $FLOAT buybacks, top traders and the Float treasury.
The site and its bot hold no keys and no funds. The bot only reads prices and transactions.
How Float pays holders
$BOBBER is a Float coin paired with SOL. The creator picks a trading fee of 1%, 2% or 2.5%. Raydium keeps part of it (0.25% while the coin is on its curve) and Float splits the rest the same way for every coin: 15% to holders, 5% to the creator wallet, 35% to $FLOAT buybacks, 35% to the top traders and 10% to the Float treasury.
Holders are paid in wrapped SOL every few minutes by Float's payout bot, pro rata to how much they hold. Fees build up until someone presses Cycle fees on the coin's Float page; Float's bot does it automatically.
Graduation
Float coins launch on Raydium LaunchLab with 1,000,000,000 supply and no mint or freeze authority, and trade on a bonding curve. At roughly $150K market cap the coin graduates: its liquidity moves into a Raydium pool and is locked forever with Burn and Earn.
The bot reads graduation from chain state, not a date: the LaunchLab pool account reports whether the coin is still on its curve or has moved to a Raydium pool. Trades are read the same way before and after.
Risks
- Memecoins are risky and most go to zero. Nothing here is financial advice.
- Under the line is not a floor. A coin can keep falling after it dips, and buying a dip can lose money.
- The Anglers board is a ranking, not a prize. Nobody is paid for a rank.
- Float, Raydium, Jupiter and Helius are third party services. Their changes or outages affect what Bobber shows.
FAQ
Does Bobber buy back or burn?+
No. There is no treasury and no buyback. Bobber shows where the price sits against its waterline and who buys the dips. What you do with that is up to you.
Who gets the creator fees?+
The creator. Float sends the 5% creator share of every trade to the creator's wallet, as it does for every Float coin. Holders get their own 15% share from Float in SOL.
Do I need to sign up for the Anglers board?+
No. It is read straight from chain. Any wallet that buys $BOBBER while the price is under the line shows up on its own.
Can I hold my money with Bobber?+
There is nothing to deposit. Bobber has no wallet that holds user funds and its bot holds no keys. You trade on Float or any Solana terminal.
Do I need to do anything to get SOL rewards?+
No. Hold $BOBBER and Float pays your share of the holder fee in wrapped SOL, which your wallet can unwrap.
