Creator fees in a vault only the streamer can open.

Every trade of a pump.fun coin pays a small creator fee. Normally that fee belongs to whoever launched the coin. With StackLive, the launch transaction writes a different rule into pump.fun's own fee-sharing config: a fixed 10% to the protocol treasury, a share the launcher chooses (10% to 90%, 50% by default) to the streamer's vault, and the remainder (40% by default) to the launcher's wallet. Then the config's admin is revoked, so the rule can never change. Each coin page shows its own split; Fees and split has the rules.

The streamer's vault is a program-derived address (PDA) computed from the platform and the streamer's permanent account ID (the numeric user ID on Twitch and Kick, the profile ID on pump.fun). It exists before the streamer has heard of us, and it holds fees until they are paid out. Payouts go to one address the streamer published or proved (a public address on their channel, a Reclaim proof, a channel code, a login, or on pump.fun a signature from the wallet that owns the profile); our server signs a short attestation that binds it, and from then on the vault only pays that wallet. See How streamers get paid.

Three platforms

Twitch · Kick · pump.fun live. Twitch and Kick are where most streamers broadcast, and many live coin streams happen on pump.fun itself, where each stream runs on a coin's page and the streamer's profile already belongs to a Solana wallet. The vault, the split and the rules are the same on all three. Only the proof of ownership differs: Twitch and Kick accounts prove control with Reclaim, a channel code or a login, a pump.fun profile with a signature from its own wallet.

Why a vault per streamer

A pooled treasury means one key controls everybody's money until someone pays it out. A vault per streamer means each balance sits at its own address, readable by anyone, and the program only releases it to the streamer. There is no instruction that lets us withdraw it, and fees that are never claimed simply stay there.

These are the rules the product is built around. Each links to the page that shows how it holds.

1. 01

   No custody

   Fees never touch a wallet we control. Each streamer has their own program-derived vault address, and the program has no withdraw instruction for us.

2. 02

   Locked split

   The split is written into pump.fun's own fee-sharing config and the admin is revoked in the launch flow. Nobody can change it afterwards, including us and the launcher.

3. 03

   Paid to their own address

   Payouts go only to a Solana address the streamer published or proved: a public address on their channel, a Reclaim proof, a channel code, a login, or a signature from the wallet that owns their pump.fun profile. No KYC, no country list, no minimums, no expiry.

   How payouts work
4. 04

   Public receipts

   Every deposit and claim is a Solana transaction. Our figures are computed from chain data, and /verify recomputes a vault in your browser against a public RPC.

   Streamer-first

   Streamers can hide or block coins that name them. We never post on their behalf, never tag them and never imply endorsement.

   Consent and opt-out

Three parts of the system rely on something other than our program. We would rather state them than hide them.

1. The attestation key

Twitch and Kick accounts cannot be verified on-chain, and the owner of a pump.fun profile is only known to pump.fun's servers, so a claim or payout binding needs a signature from our backend saying “this wallet belongs to the owner of Twitch user 123”. Whoever holds that key could sign a false statement. The mitigations: the key lives in a hardware-backed KMS, rotating it is timelocked for 48 hours, every attestation we issue is published at /trust/attestations, the first claim binds a payout wallet that later attestations cannot change without a 72-hour public delay, and large first claims can be delayed. Details in the security model.

2. pump.fun community takeover

pump.fun's global admin can reset a coin's sharing config through its community-takeover (CTO) process. That is outside our control. We index the ResetFeeSharingConfigEvent and flag affected coins with a “fee split reset by pump.fun” banner. Fees already distributed to a vault are unaffected.

3. pump.fun has no official API

We read pump.fun profiles and live status through the public endpoints its own website uses. pump.fun can change or rate-limit them at any time. If it does, pump.fun lookups and new pump.fun bindings pause; existing vaults, balances and bound wallets are on-chain and unaffected.

The on-chain vault program is not deployed yet, so the site runs in DEMO mode. Here is exactly which parts are real and which are simulated.
