CHAIN
launch

how it works

Every coin can be a parent.

Launch a pump.fun coin quoted in another pump.fun coin. Buying yours buys theirs.

Follow a trade

Pick a coin and a side.

  1. SOLyour wallet
  2. ROOTG0 · quoted in SOL
  3. CHILDG1 · quoted in ROOT
  4. GRANDG2 · quoted in CHILD

Buying GRAND with SOL is 3 hops in one transaction. Every coin above it gets bought on the way down.

01

Pick a parent

Any pump.fun coin can be a parent: one you made, one you like, one that’s graduated. Or pick nothing and start a new root in SOL.

Your curve is priced in it

Instead of holding SOL, your bonding curve holds the parent coin. Market cap, progress and graduation are all measured in the parent.

Buys climb the chain

You still pay in SOL. We route it through every coin above yours in one transaction, so each buy of a child is also a buy of its whole lineage.

SOL→ROOT→CHILD→YOU

Chains branch

Anyone can launch under your coin, and under theirs. A root with a busy tree beneath it gets bought by every branch.

How deep it goes

pump.fun decides how many generations a chain can have. Its program allows up to G5; the limit it enforces today is G2. We read it live, so deeper generations unlock here the moment pump raises it.
