Fee-routed launch

The three steps

1. 1 · Create the coinOne transaction signed by your wallet and the new mint key: a memo committing to your exact route (owner, mint, fee wallet, number and every recipient and share), then Pump’s create_v2 with the router address as creator. No tokens are bought. The page saves a public plan in this browser; export it.
2. 2 · ActivateThe second approval. It creates the router account with your recipients and shares and locks in the VEYDUCT fee rate in force at that moment. the routerA second approval from the same wallet creates the router account with those recipients and shares and copies the VEYDUCT fee rate in force at that moment. The page checks the activated router matches the saved plan exactly.
3. 3 · Collect and payOn Fee routes: Collect runs Pump’s sweep and then the router’s collect in one transaction (a graduated coin adds a PumpSwap sweep and a transfer to Pump first). Pay sends one destination what it has earned. A keeperAn optional second wallet you allow to collect and pay for you, until a slot you choose. It can never change recipients or send money anywhere else. you allow can do both for you.

Accounts involved

Every address is derived from fixed seeds (a PDAProgram-derived address: computed from fixed words and keys, so the page and the program always find the same account and nobody can swap in a look-alike.), so the page and the program find the same accounts and nobody can swap in a look-alike.

Who can do what

• ActionWho signsRules the program enforces
• Create the coinYou and the new mint keyPump records the router address as creator. The memo commits to the route; a changed route no longer matches.
• ActivateThe wallet that launchedThe router address includes that wallet, so no other wallet can create it. 2 to 6 distinct recipients, shares total exactly 100%, fee wallet fixed.
• CollectOwner, or a keeper allowed to collectOnly from this coin’s curve and this router’s creator vault. Refused if nothing arrives.
• PayOwner, or a keeper allowed to payOnly to the address written into the router for that destination, and only what it has earned and not yet received.
• Allow or revoke a keeperThe owner onlyOne keeper, with collect, pay and recognise-deposit permissions, until a future slot. It cannot be the owner or the router.
• Change recipients, shares or rateNobodyNo instruction edits them, closes the router or withdraws to any other address.

Sweeping Pump fees is open to anyone, but a sweep can only move them into the router’s own creator vault. Only the router’s collect moves them on, and only to the router.

Payout math, with a worked example

The router keeps one running total of everything it has collected. Every payout is worked out from that total, so collecting often or rarely gives everyone the same result.

1. VEYDUCT feefee = total × rate ÷ 10,000Rate in basis pointsHundredths of a percent: 100 basis points is 1%, and 10,000 is 100%.: 100 is 1%. Locked in when the router is activated.
2. Each recipientearned = (total − fee) × share ÷ 10,000Divisions round down. What rounding leaves stays in the router and is never paid out.
3. A payoutpaid now = earned − already paidRefused when that is zero.

Example: Example Coin, You 50% · Team 30% · Community 20%

1. Traders move 20 SOL.creator fee 20 × 0.30% = 0.06 SOLIt waits on the curve. Pump’s 0.95% protocol fee goes to Pump.
2. You collect 0.06 SOL.fee 0.0006 · net 0.0594You earn 0.0297, Team 0.01782, Community 0.01188. You, Team and VEYDUCT are paid.
3. Traders move 7.77 SOL more; you collect 0.02331.total 0.08331 · fee 0.0008331 · net 0.0824769Earned so far: You 0.04123845, Team 0.02474307, Community 0.01649538.
4. Pay everyone.You get 0.01153845, Team 0.00692307, Community its whole 0.01649538, VEYDUCT 0.0002331.

Rounding: with shares of 33.33%, 33.33% and 33.34% and 1,000,001 lamports collected, the fee is 10,000 lamports, the recipients earn 329,967, 329,967 and 330,066, and 1 lamport stays in the router. The practice run uses the same arithmetic as the program, so you will see these numbers there.

VEYDUCT feeOf everything the router collects, paid to the fixed VEYDUCT fee wallet. No VEYDUCT launch fee on this kind of launch.

1% · max 2%

Rent stays in the accounts for good: the router program has no instruction that closes a router. Pump’s own trading fees (creator 0.30%, protocol 0.95% when this release was built) are paid by traders, not by you.

Edge cases and what can go wrong

Terms used on this page

Fee router

A VEYDUCT program account recorded as the coin’s creator. It receives every creator fee and can only pay it to the fixed wallets written into it.

Creator fee

The share of every trade Pump pays the coin’s creator: 0.30% on the curve when this release was built. Here the creator is the router.

Activation

The second approval. It creates the router account with your recipients and shares and locks in the VEYDUCT fee rate in force at that moment.

Creator vault

Pump’s holding account for a creator’s fees. Sweeps fill it; the router’s collect empties it down to its 0.00065024 SOL rent minimum.

Keeper

An optional second wallet you allow to collect and pay for you, until a slot you choose. It can never change recipients or send money anywhere else.

Public plan

A JSON file describing your launch: owner, coin, recipients, shares and number. It holds no private key. You need it to activate from another device.

PDA

Program-derived address: computed from fixed words and keys, so the page and the program always find the same account and nobody can swap in a look-alike.

Basis points

Hundredths of a percent: 100 basis points is 1%, and 10,000 is 100%.

Bonding curve

Pump’s built-in market for a new coin. A formula sets the price: each buy raises it and each sell lowers it.

Lamport

The smallest unit of SOL: 1 SOL is 1,000,000,000 lamports.
