Every pump.fun buyis a public diary.

Copy-traders, snipers and wallet trackers read it in real time. Here is the same trade, seen by a block explorer, both ways.

How a private trade works

  1. 01

    Shield

    Move SOL from any wallet into your ring. From here on your balance is encrypted on-chain. Only your viewing key can read it.

  2. 02

    Trade

    Buy or sell any pump.fun coin. A relayer pays from your ring through a single-use wallet and shields the coins straight back. One atomic bundle, no link to you.

  3. 03

    Exit anywhere

    Unshield SOL or coins to a fresh address whenever you want. On-chain, nothing connects it to the wallet you started with.

A launchpad with nothingto show.

Hidden dev buy

Launch without painting a target on your wallet.

Your dev buy routes through the ring at creation. Bubble maps show a single-use wallet that shielded and vanished, not a creator holding 8% of supply.

Anonymous ring

Asset, amount, sender and receiver: all encrypted.

Proofs

ZK

Groth16 proofs, generated in tens of milliseconds.

Viewing keys

Prove a balance to whoever you choose. Nobody else.

Any coin

Bonding curve or PumpSwap. Paste a mint, trade it shielded.

Exit

Unshield to a fresh wallet. No trail back.

Questions

Helius' Solana Privacy Rings are shielded pools with encrypted on-chain balances. Transfers inside a ring are proven with Groth16 zero-knowledge proofs, so the chain can verify them without seeing amounts or, in the anonymous ring, who sent what to whom.

The pump.fun program still sees a buy, but not yours. Cloak pays from your encrypted balance into a single-use wallet, buys, and shields the coins straight back. The single-use wallet is never reused and is emptied afterwards.

Yes. Any pump.fun coin, bonding curve or graduated to PumpSwap, can be traded through the ring. Coins launched here also get a hidden dev buy and a ring interface from block one.

Yes. Cloak holds your ring's keys, encrypted, and only acts on requests from your signed-in wallet. You can withdraw everything to any address at any time from My ring.

Yes. Share a viewing key with anyone you choose (an exchange, an accountant) and they can read your ring balances without being able to move them.

The usual pump.fun fee plus a small relayer and prover fee, shown on every quote before you confirm.
