How Drench works
Drench lets you buy and sell pump.fun coins directly with other holders. Trades happen at or under the chart price and never touch the bonding curve or the pool, so the chart doesn't move.
You can also launch your own pump.fun coin here. Its creator fees buy back your coin, or up to 10 coins you pair it with, and most of what's bought is airdropped to your holders.
The header has six pages. Feed lists coins and how many OTC orders each has. OTC shows every coin with open orders and how it works. Orders shows your own orders, with each order wallet's balance and every refund. Launch creates a coin. Wallet shows your Phantom wallet. $DRENCH shows how much $DRENCH the fees have bought back and burned. Docs is this page.
Getting started
Sign in with your email, then connect Phantom.
Phantom is your wallet on Drench. Your side of an order comes from it, and your coins and SOL come back to it. Drench never holds your Phantom keys.
Every order gets a wallet of its own, made just for that order and managed by Privy. You send your side of the order there. The wallet's rules only let it pay three places: you, Drench's fee wallet, and the order you're matched with, once that match has been checked. Drench never holds the wallet's keys.
Some coins, such as Token-2022 coins, may still use the older way: your coins or SOL stay in your wallet. You approve the order in Phantom (SOL is wrapped so it can be approved), and Drench can move only that much, only into a matched trade. Each order shows which way it's held.
Posting an order
Open any coin from the Feed. Its OTC panel is on the right. Pick buy or sell.
Set the amount with the slider. Buyers pick how much SOL to spend. Sellers pick a share of the coins in their Phantom wallet.
Then pick a price. Auto uses the chart price with a small automatic discount. Set my price lets you slide up to 25% above or below the chart. Your order never buys above or sells below the price you set.
Drench shows what you get compared with trading the same amount on the market, and suggests splitting the order into about five transfers. You can change the number.
Post it, then fund it: send your coins (selling) or SOL (buying) to the order's wallet. You can deposit straight from Phantom, or copy the address from the Orders page and send from any wallet. The order goes live as soon as it's funded. Send only that coin or SOL, and never send anything to the address of an order that has ended.
Sent too much? Anything over the order amount is sent back to you when the order ends. If the order is held in your own wallet instead, approve it in Phantom and it goes live once the approval confirms.
How trades fill
Buy and sell orders on the same coin match automatically, and the trade settles on its own. Nobody has to sign anything. Each match fills in a few transfers, about a minute apart, each at that minute's chart price.
Before the first transfer, the matched order's wallet is checked and added to your order wallet's list of who it may pay. It's taken off again when the match ends. Each transfer swaps the coins and the SOL between the two order wallets in one transaction, and sends each side its proceeds. Neither side can end up with nothing.
A buyer never pays more than the market would charge for that piece. If the chart moves more than 5% from its 10-minute average, transfers pause until it settles.
Why it helps: selling a big bag on the market pushes the price down, and buying one pushes it up. Both also pay pump.fun's fee. OTC skips both. A transfer only goes through when both sides still do better than the market after Drench's fee; otherwise it waits.
Your orders
Every coin page lists its open buy and sell orders at the bottom. The Orders page shows all of your orders and how much each has filled. An order with a wallet of its own also shows that wallet's address and what it holds right now.
Cancel any time and trading stops before the next transfer. Whatever is left in the order's wallet, plus anything you overpaid, is refunded to you within a few minutes. The same happens when an order expires.
Refunded orders move to the Refunded tab on the Orders page, with what came back and a link to the refund transaction. Filled orders are under Finished.
Orders that are never funded close after 24 hours. Every order ends after 7 days. If something arrives at an order wallet after its order ended, it's sent back too.
An order that stayed in your wallet never moved what didn't trade. Remove the approval in Phantom, which also unwraps your SOL.
Orders can be worth 0.25 to 1,000 SOL. Any SOL-paired pump.fun coin works, on the bonding curve or on PumpSwap.
Launching and pairing
The Launch page creates a pump.fun coin. Pick a name, ticker and image, and an optional first buy. Phantom approves one payment for the launch cost and your buy, and your coin's tokens come back to that wallet.
A launch costs 0.1 SOL plus 2% of your first buy. 0.02 SOL is Drench's fee, about 0.03 SOL pays pump.fun and the network, and 0.05 SOL stays in your coin's own wallet to pay for its fee cycles. If the launch fails, the payment is refunded.
Your coin's creator fees are collected and all of them are spent buying coins on the market. By default that buys back your own coin. You can pair it with up to 10 other coins instead, and the fees are split evenly across those. Any coin Jupiter can buy can be paired.
75% of the coins bought are airdropped to your holders, in proportion to how much of your coin they hold. Drench keeps the other 25% to sell on OTC, so buyers can get supply without moving the chart.
Fees
Drench takes 2.5% from the buyer and 2.5% from the seller on every OTC trade. There is no pump.fun fee, and Drench pays the network fees.
All of the fee goes back into $DRENCH: it buys $DRENCH on the market and the coins bought are burned.
Safety
Each order wallet is held to its own rules, which Privy enforces: it can only pay you, Drench's fee wallet, or the one order it's matched with right now. That order is added by a separate service only after it has checked the match, and removed when the match ends. Privy holds the wallet's keys, not Drench. An order that stays in your wallet can move no more than you approved, and only to the wallet you were matched with.
Every trade is checked before it's signed. If it doesn't move exactly the agreed coins and SOL, it isn't sent.
Every deposit, trade, refund and approval is an on-chain transaction you can check on Solscan, and every order wallet links to it.
Memecoins are risky. Only trade what you can afford to lose.
