PLOVERWalk into the jaws.
Walk out whole.
OTC blocks for Solana tokens. A seller signs once for one buyer, the buyer signs later, and a single transaction swaps tokens for SOL. The pool never opens its mouth, and PLOVER never holds a thing.
Sell a block How it worksIn the jaws
List yoursBlocks waiting for a buyer. Ask for one, and the seller can sign it for your wallet alone. A bot can't take the discount and dump it into the pool.
Walked out
Blocks that changed hands, one transaction each, none of them through a pool.
How a block walks out
A whale who sells 3% of supply into the pool bites every holder at once. A block goes around the pool: the seller and one buyer swap directly, at a price they both agreed to.
The seller lists
Token, size, price in SOL, and an optional lock. The wallet signs a message. Nothing moves.
A buyer asks
Buyers ask with a signed message. The seller sees every wallet that asked, or names one up front.
The seller signs for one buyer
The swap is signed against a durable nonce, not a recent blockhash, so the signature waits for days instead of a minute.
The buyer walks out
The buyer adds a signature and sends. Tokens and SOL change hands in one transaction, or nothing happens at all.
Why there is always a named buyer
A discounted block open to anyone is a free meal for a bot: it would take it and sell into the pool in the same second. Each block here is signed for exactly one wallet.
A better price for holding
The seller can ask the buyer to hold. The tokens then land in a Jupiter Lock escrow in the buyer's name until a date, and nobody can cancel it, the seller included.
What PLOVER never touches
No escrow of ours, no program of ours. The swap is plain transfers, the lock is Jupiter Lock, and your browser builds every transaction.
Backing out
Until the buyer sends it, the seller can close the nonce. The signed block can then never land, and the nonce rent comes back.
Sell a block
Your tokens stay in your wallet until a buyer takes the block. If you sell them somewhere else first, the block just fails.
Listing is free. Signing for a buyer opens a nonce account (about 0.00145 SOL, back to you when it closes). A lock adds about 0.003 SOL of escrow rent.
