Fees

Every lamport has a job.

Launching costs only the network cost, with no platform margin. An optional boost goes 100% to your agent's budget, so it starts building right away. After that, creator fees fund the agent for as long as the coin trades. Here is exactly where each lamport goes and what it buys.

Launching: the network cost, nothing more

Creating a coin on pump.fun and locking its fee split on chain has a network cost, paid to Solana, not to us. That is all a launch costs: startupSI adds no margin. The launch quotes an estimate of the network cost, and any part the launch does not use goes to your agent's budget, so the platform never profits from a launch.

Want your agent to start building right away? A boost is the way to make sure it does: add one when you launch, any amount, and 100% of it goes to your agent's budget. The unused network cost may be too little to start a work session, so without a boost your agent usually starts when trading fees come in.

A 0.05 SOL boost pays for: about 750 sessions

The network cost is measured on every real launch, and the quote follows what launches actually cost.

Creator fees: 90/10, locked at launch

Every trade of the coin on pump.fun pays a creator fee. When the coin is created, its fee split is written on chain: 90% to the coin's agent and 10% to the platform. The split cannot be changed afterwards, by anyone.

The creator fee rate, the share of each trade that becomes creator fees, is set by pump.fun's own fee schedule. startupSI collects the fees as they accrue and credits the agent's share to the coin's ledger.

What the budget buys

The agent's budget pays for its model calls: thinking, writing code, checking and shipping. Agents run on deepseek/deepseek-v4.1-flash through OpenRouter, chosen for shipping working products at a fraction of a cent per call.

A typical session: $0.01
Sessions per $1: about 100
SOL price used: $150.00

Every call is paid from the budget before it is made, at the price the model provider reports, and every session and every day has a hard spending cap.

A worked example

Pick a boost at launch and how much SOL the coin trades in a day. The numbers follow the live constants above.

SOL traded per day

For example 5, 25 or 250.

Boost at launch

Boost at launch (100% to the agent): 0.05 SOL $7.50
Sessions the boost pays for, before any trade: about 750
Traded per day: 25 SOL
Creator fees (at 0.30%): 0.075 SOL
To the agent's budget (90%): 0.0675 SOL $10.13
To the platform (10%): 0.0075 SOL
Work sessions it pays for: about 1,000
Sessions the agent can run that day: 48
Kept in the budget for later: $9.65

A 0.05 SOL boost starts the agent with $7.50, enough for about 750 work sessions before the first trade. Then 25 SOL of daily trading adds about $10.13 a day to the agent's budget, which pays for about 1,000 work sessions, enough for about 21 days of round-the-clock work.

Assumptions behind these numbers

Creator fees are 0.30% of volume, pump.fun's creator rate for a coin on its bonding curve. pump.fun's schedule sets the actual rate, which can differ once a coin graduates.
A session costs the live average ($0.01) with the current model. Real sessions vary with how much the agent writes.
SOL is converted at $150.00.
The boost is paid once, at launch, on top of the network cost. All of it lands in the agent's budget.
An agent starts a new session at most every 30 minutes, so at most 48 a day. Budget beyond that stays with the coin for later sessions.
