Performance Share
Swap.io is built around a simple principle: you should only pay when your swap performs better than expected. This page explains what that means and how it works.
To keep the platform sustainable without introducing traditional platform fees, Swap.io uses a performance-based share that applies only when a trade executes with positive slippage.
What is positive slippage?
When you submit a swap, you receive a quoted output amount. Sometimes, due to market movement or improved routing, the final executed output is higher than the quote.
That extra amount is called positive slippage.
You never receive less than the quoted amount
Positive slippage means your trade executed better than expected
Simulated quotes as the baseline
Swap.io uses real-time transaction simulation to calculate quotes before submission.
This means:
Quotes already account for real slippage and execution conditions
The quoted output is very close to the final on-chain result
Any remaining positive slippage is typically very small
Because simulation is used as the baseline, differences between quoted and executed output are usually measured in hundredths of a percent.
How performance share works
When a swap executes with positive slippage relative to the simulated quote, a portion of that extra output may be shared to support the platform.
Key points:
Performance share is taken only from the amount above the simulated quote
Your quoted output is never reduced
If no positive slippage occurs, nothing is shared
In practice, the shared amount is usually extremely small
By default, the performance share is set to 50% of positive slippage.
Exact In vs Exact Out swaps
Performance share applies only to Exact In swaps.
Exact In: You specify the input amount, and the output may improve slightly if execution conditions are favorable. → Performance share may apply only to positive slippage.
Exact Out: You specify the exact output amount you want to receive. → No performance share is applied, regardless of execution.
This ensures that users who require a fixed output are never affected.
Why Swap.io uses performance share
Swap.io does not charge platform fees.
Instead, performance share helps support:
High-performance Solana infrastructure and RPC nodes
Real-time simulation and routing systems
Gas-efficient execution and upcoming gasless flows
Ongoing maintenance, security, and feature development
This model allows Swap.io to remain free to use while aligning platform support with improved execution.
Is this a fee?
No.
Performance share is not a platform fee and does not affect quoted prices.
It:
Applies only when execution exceeds the simulated quote
Never reduces expected output
Results in very small amounts in practice
Can be adjusted or disabled by the user
User control
Performance share is configurable from user settings.
Users can:
Keep the default share
Increase or reduce the percentage
Disable it entirely
Settings always apply before swap execution.
XP and rewards
Performance share helps fund Swap.io’s XP and community rewards system.
When performance share is disabled:
XP rewards are paused
Referral and downline XP does not accumulate
This keeps incentives aligned with active platform support.
Transparency and intent
Swap.io’s goal is to remain:
Non-custodial
Transparent
Fair by design
Free of traditional platform fees
Performance share exists to keep the platform sustainable while ensuring users only contribute when execution improves beyond already-simulated expectations.
