otc desk · solana · private by default
trade the block in the dark.
list a token block, get sealed bids, settle in one private transaction. no chart, no trace of who, what or how much.
01 / visibility
what the world sees vs what you see
same settlement, two views. the explorer gets a sealed transaction. the two parties hold the viewing key.

02 / flow
four moves. one sealed settlement.
- 01
list
pick a token from your wallet, set a size or size range, a floor price and how long the auction runs. the board only shows size as a share of supply.
- 02
sealed bids
buyers submit encrypted bids. nobody, us included, sees a bid before the auction closes. when it closes, the best valid bid wins.
- 03
fund from ring balance
the winning buyer funds from a balance already inside the privacy ring, so no fresh public deposit points at this deal.
- 04
settle atomically
token and payment swap in one transaction submitted by a relayer. it either fully happens or nothing happens.
03 / desk
built for size, not for the chart
anonymous addresses
a relayer submits every transaction, so neither party's wallet signs anything visible on-chain.
blind auctions
multiple encrypted bids per block. the best one wins. losing bids are never revealed.
private vesting
buyers can take a block locked over 7 or 30 days through a private escrow, often at a deeper discount.
no-trace funding
fund from your ring balance. if an action would need a public deposit, we warn you first.
chart vs block
see the estimated price impact of dumping on the chart next to a block price before you list.
holder share
part of desk fees goes to $DARKBLOCK holders, paid from one public wallet with every tx linked.
04 / estimate
chart vs block
paste a token address and an amount. we ask jupiter what a market sell would do, then compare it to a block at the discount you set.

06 / limits
what darkblock won't do
never hold your funds
settlement is atomic through the ring. there is no darkblock wallet holding deposits.
never read your bids
bids are encrypted in your browser. we only see a commitment until the auction closes.
never hide the discount to market
every block shows its floor versus market so you know what you are giving up.
never touch sanctioned wallets
compliance screening runs inside the privacy ring. flagged wallets can't use the desk.
never promise buyers or prices
a block can close with no bids. there are no guaranteed fills, prices or returns.
