The rules

Created

All 21,000,000 coins, with 6 decimals, are minted into the curve when the coin launches. There is no presale, no team allocation and no vesting. The creator gets coins the way everyone else does: by buying them.

Mint authority

Revoked. The configs use DBC's fixed-supply token setting, so neither the curve nor anyone else can ever mint again.

Freeze authority

Revoked. No one can freeze the coins in your wallet.

Metadata

Locked. Name, ticker and image can't be edited after launch.

Checked live

Each coin page reads the mint from Solana when you open it and shows the supply and both authorities exactly as the chain reports them. You don't have to take this page's word for it.

Paired with

cbBTC, Coinbase's wrapped bitcoin on Solana. It has 8 decimals, so its smallest unit is exactly 1 sat. Prices read in sats per coin first, dollars second.

Between epochs

No jump. Each epoch opens at the exact price the last one closed at. What changes is the pace: every segment of the curve holds √2 less liquidity than the one before, so the same BTC moves the price further.

Epoch names

Each epoch carries the block subsidy bitcoin paid in the same era: Epoch 1 50 BTC, Epoch 2 25 BTC, Epoch 3 12.5 BTC, Epoch 4 6.25 BTC. A label, not a payout.

Tiers

The launcher picks one of four tiers. A tier is only a graduation target: it scales every price on the curve and nothing else. Supply, epochs, fees and modes are identical across all four, and the choice is permanent because each tier is its own config.

Graduation

When

The moment epoch 4 fills. DBC closes the curve and opens a Meteora DAMM v2 pool at the curve's final price, holding all the BTC raised plus the coins the curve didn't sell.

Why that split

It falls out of the math rather than a setting. The pool has to match the raised BTC at the final price, which takes 3.33M coins; the four epochs sell the rest. Same split on every tier.

Dust

DBC keeps a 0.01% sliver of supply (2,100 coins) as rounding room. At graduation it goes to the keeper, which burns it with the memo halvd burn.

Meteora

20% of each fee. It's Meteora's protocol fee; halvd has no say over it.

Fee share

60% of each fee. Where it goes is the coin's mode, picked at launch. Each mode is its own set of configs, so the choice is written on chain and can't be switched later.

Platform

20% of each fee, claimed in BTC by the keeper. It sends 25% of every claim to the treasury (memo halvd treasury) and spends the other 75% on $HALVD, burning every coin it buys (memo halvd burn). Per fee, that's 15% burned and 5% to the treasury. Until $HALVD launches, the burn part waits with the keeper.

How it's wired

Creator mode: the config itself pays the creator 75% of what's left after Meteora and the keeper 25%. Every other mode: that whole remainder goes to one halvd key (distributor or miner), which passes 25% of each claim on to the keeper with the memo halvd platform share.

The first seconds

Why

Bots that buy in a coin's opening seconds pay up to 49.99%. The fee steps down every second and settles at 1% from second 3. Whatever a sniper pays is split like any other fee.

Your first buy

A buy bundled into the launch transaction pays 1%, not the snipe rate: DBC charges the first swap of the creation transaction the lowest fee on the schedule. It lands in the same transaction as the launch, so nobody can get in ahead of it.

No first buy

The first outside buyers may pay the snipe rate instead. Bundling a first buy keeps that money out of a bot's plan.

After graduation

Pool fee

1% per trade on the DAMM v2 pool, collected in BTC.

Liquidity

100% permanently locked, 0% withdrawable. The positions earn fees but can never be pulled, by anyone.

Positions

Creator mode: 80% to the creator, 20% to halvd's keeper. Every other mode: 100% to the mode's claimer key, and its pool fees take the same path as the curve fees.

Who holds it

The config pays this mode's fee side to halvd's distributor key. It passes the platform part to the keeper and keeps the holders' 60%-of-each-fee share for them until it's claimed.

Snapshots

Every 60 seconds in a coin's first 1 hour, then every 10 minutes. Each one fires at a random moment inside its window, so there's no second worth timing a buy around.

What one pays

The holders' share of every fee that arrived since the previous snapshot, split pro rata by balance.

Who counts

Any wallet holding at least $10 of the coin at that moment, valued at the coin's own price in sats and the BTC/USD price of the moment. All of a wallet's token accounts for the coin are added together.

Who doesn't

Pools, vaults and other program-owned accounts, every halvd role key (keeper, distributor, miner, sender) and the treasury.

Nobody qualifies

The amount stays in the coin's pot and goes out with the next snapshot.

Claiming

From 500 sats owed, on the coin page or in Wallet. You sign the claim and pay its network fee, plus a one-time account rent if your wallet has never held cbBTC. Credits don't expire.

Can be zero

No trades, no fees, nothing to split. Long quiet stretches are normal.

Everything else

Same distributor, snapshots, $10 minimum, exclusions and claims as Holders mode. The one change: a wallet's slice is balance × weight instead of balance alone.

Clock starts

At the first snapshot that finds your wallet holding the coin. Coins bought between snapshots start counting at the next one.

Clock resets

When a snapshot finds a lower balance than the one before. Selling resets it, and so does sending coins to another wallet. You drop back to 1×, and the receiving wallet starts its own clock from zero.

Buying more

Blends the clock instead of resetting it: your hold time becomes the average across your coins, with new coins at zero. Hold 1,000 coins for 1 day, buy 1,000 more, and your clock reads 12 hours: the weight moves from 3× to 2× and climbs back from there.

Binding

The creator signs the launch with exactly one payout memo. That address is the coin's payee for good: no setting, key or admin action can change it. A launch without exactly one valid memo binds nothing.

When it pays

Automatically, once 12,000 sats are owed and the bridge costs 10% or less of the payout. A coin that has gone 90 days without a payout is paid from 6,000 sats at up to 20%, so slow coins still get paid.

Bridge

Relay turns cbBTC on Solana into native BTC and sends it to the bound address. Relay's fee comes out of the payout.

Receipts

Every payout shows three numbers: gross, bridge fee and net, next to its transactions.

Until then

The share waits with the distributor key, as in Holders mode.

Sender key

A dedicated sender key signs each bridge deposit. It's funded with one payout at a time and holds nothing in between.

Binding

Two choices in one memo, signed by the creator at launch: where found blocks go (holders or burn) and how the rig mines (pool or solo). Both are final.

Who holds it

The miner key claims this mode's fee side, passes the platform part to the keeper and spends the rest on hashrate.

Renting hash

Hashrate is rented on Braiins Hashpower as spot bids, pointed at CKPool's solo pool under the coin's own worker.

Pool

Every pool-mode coin hashes toward one shared address. A found block is split by the hash each coin delivered since the last one, and the coin whose worker found it takes 10% first.

Solo

The rig hashes to its own address and keeps the whole block. It finds one far less often.

Every block

5% buys $HALVD and burns it.

Found block

After 100 confirmations the reward is swept back to Solana as cbBTC. holders: credited to the coin's holders and claimed as in Holders mode. burn: spent buying the coin and burning it.

Odds

Rented hash finds blocks rarely. A rig can spend everything it's given and find nothing; the fees are spent on hashrate either way.

How

One transaction from your wallet: a burn of $HALVD plus the memo naming the coin. A burn without exactly one valid memo, or under the minimum, doesn't count.

Minimum

1,000 $HALVD per boost.

Fade

Full weight when it lands, then down in a straight line to zero over 24 hours. Burn 10,000 and it counts as 5,000 after 12 hours, and as nothing after 24.

Stacking

Boosts on one coin add up, whoever sends them.

Ranking

The most boost left right now ranks first. To pass the leader, burn more than it has left.

Who gets it

Nobody. Burned coins leave the supply for good: not halvd, not the creator, no one receives them.

Status

Boosts need $HALVD, which hasn't launched yet.

Real money

Every trade uses real cbBTC. A coin can go to zero, and you can lose everything you put in.

Burns

Burning $HALVD reduces its supply. That is all it does. It doesn't hold up a price, and nothing on this site promises one.

Fee shares

Every payout on this page is funded by trading fees. They follow volume and can be zero.

Hashrate

Rented hashrate may never find a block.

Third parties

Payouts and rigs depend on Relay, Braiins Hashpower and CKPool. Any of them can fail, pause or change terms.

halvd's jobs

Snapshots, payouts, rigs and buybacks run on halvd's servers with halvd's keys. If those stop, these stop until they're back. Fees already earned stay on chain meanwhile.

The house coin

$HALVD may not exist yet. Until its address appears on this site, any coin using the name isn't it.

Every figure on this page is computed from the constants the configs are built with. If this page and the chain ever disagree, the chain is right.
