How it works

pumpsv lets anyone launch a coin that is tradeable the moment its listings are broadcast β€” no presale, no team allocation, no seeding liquidity. And unlike anywhere else: we never hold your coins or your keys.

1 Β· Your wallet is created in your browser. The secret key never leaves your device.
2 Β· Pick a coin you like β€” check its creator lock πŸ”’ (locked supply cannot move before its block; the unlocked part can).
3 Β· Buy any amount off the rising price ladder. Payment and coins settle in ONE transaction.
4 Β· Sell any time β€” your coins list as an on-chain order only you can cancel, or sell to a standing bid.
5 Β· Lock behind creators you believe in. Conviction is public, ranked, and provable.

What's really happening underneath

Launching
Several signed transactions, every one signed by you: the deploy (BSV21 mint + image inscription + origin stamp), the ladder of covenant-locked sell orders, and your creator lock if you set one. Never one tx. Looks like a curve β€” it is not one. There is no pool, so there is nothing to drain. The first 69 origin-stamped launches have their deploy and listing miner inputs funded by the platform β€” one slot per wallet; a second launch from the same wallet is self-funded, and after 69 every launch is. "Free" never means zero sats on the network. The platform never holds the deploy key, and trades stay 0 bps platform. No better sort, no featured row, no Holo favour β€” launch 1 and launch 69 look the same on the board.
Trading
Each order is coins locked in a Bitcoin script: "anyone may take these by paying X to the seller; only the seller can cancel." Partial fills mean any amount works. Paying and receiving are the same transaction β€” you cannot pay and not receive. And there is no committee here: no validator vote, no operator, nobody who can force-settle, delist, or unwind your trade. It's a covenant, not a committee.
Locks & rankings πŸ”’
nLockTime β€” Bitcoin's built-in timer β€” freezes coins until a block height. Creators lock supply (coin rank); supporters lock BSV behind creators (conviction + supporter ranks). Miners enforce it, we just display it. Creator supply locks all follow one standard β€” three tranches at 6 / 12 / 18 months, thirds unlocking over a year and a half, no single dump-day cliff β€” so every coin rank is comparable. Supporter locks are yours to shape: any amount, any unlock date, six months minimum. Weight grows with time and caps at 4 years, so no thousand-year whale ever owns a leaderboard β€” but if you want to lock till the year 3025, we'll salute you.
Coin chat
Every coin has its own chat. Every reply and every username is a transaction (MAP + BAP protocols) β€” permanent, uncensorable, rebuildable by anyone. Your profile collects your replies across all coins. And you can buy without leaving the thread: type /buy β€” the app recognizes it as you type and floats a private preview of the cheapest whole listing on this coin, the same one the Buy tab takes first. No amounts, no dollars, no ticker: the page is the identity. A command never signs; only your wallet's preview does. A command never becomes a comment. Receipts are a separate, opt-in second transaction. Feeling inspired? /create (or /mint) opens the coin creator right from any thread.
The database
Our servers only mirror the chain for speed. If pumpsv vanished tonight, every coin, order, lock and post still exists β€” yours, forever.
Support
We never DM first. We will never ask for your seed words β€” not in chat, not in "support," not ever. Anyone who does is a thief wearing our name.
