Fees & Billing

Platform Fees

PolyMirror charges a transparent execution fee on confirmed trades executed through the platform. The current beta fee rate and minimum fee are shown in-app.

PolyMirror charges a small fee on each successfully completed trade. You only pay when an execution confirms. Skipped or rejected trades are never charged.

How fees are calculated

Your fee is a small percentage of the trade amount, with a minimum floor to keep it simple.

• Fee rate: A percentage of your trade size (shown in-app)
• Minimum fee: A small floor so tiny trades don't incur negligible fees
• Only charged when a trade successfully fills
• Fee balance tracked separately from your trading funds

ℹ️

Example: If a $100 execution confirms at a 1% fee rate with a $0.10 minimum, the platform fee is $1.00 (1% of $100, above minimum). This is accrued and settled separately from your trading balance.

Fee Settlement

Your fees are collected periodically from your wallet automatically - you don't need to do anything. Here's how it works:

Fees accrue after each confirmed trade
Fees are collected from your wallet automatically on a periodic basis
Settlement is deducted from your wallet
You receive confirmation of each settlement
If a payment fails, you can retry it from Account Settings

⚠️

Important: If fee settlement fails due to insufficient funds, copy-trading will be paused until the outstanding balance is settled. Check your fee status in Account Settings.
