Traders earn for discipline
Most copy-trading platforms rank traders by return and charge you regardless of how they behave. PropChange flips that: every strategy publishes a Seat Contract derived from its own history, and your fee is only released to the trader if they keep it.
“+3%/month, 4% max drawdown, 11/12 contracts kept” should beat “+40%/month, 60% max drawdown”. We build the product so that it does.
Strategies & professional analytics
A trader is a person; a strategy is the product. Each strategy runs on its own dedicated sub-account, so risk and PnL are attributable.
Deposits and withdrawals never count as performance.
Return is always shown next to drawdown and volatility.
Martingale, averaging down, hidden tail risk, thin samples.
Closed and failed strategies stay visible forever — so no one can open ten strategies and only show the three winners.
Capacity & Seats
Every follower order moves the market. Capacity is the most follower capital a strategy can absorb before slippage eats a third of its edge. It is split into Seats — each Seat lets you copy up to a fixed allocation of your own capital.
Example: Capacity $300,000 ÷ $3,000 per Seat = 100 Seats. 87 are taken — the price rises as the last ones fill.
Bigger holders never get signals first. All followers of a signal execute in the same batch, in randomized order.
The Seat Contract
Before each Epoch, a contract is generated from the strategy's history plus a buffer. The trader may tighten any rule, never loosen it.
Hist. max 12.0% × 1.25
p99 daily loss 2.5% × 1.2
p95 leverage 5x × 1.2
p95 position 20% × 1.5

Typical 18 trades / Epoch
The contract does not promise profit. A trader can have a losing Epoch and still be paid if every rule was respected.
Epochs & escrow
You pay the Seat Fee in USDC on Solana. It sits in an on-chain escrow for the 30-day Epoch. At the end, a signed settlement report releases it — or refunds it.
- Hard breach (drawdown, daily loss, leverage, position size, prohibited instrument): copying stops, full refund.
- Soft breach (minimum activity, repeated data gaps): pro-rata refund.
- Fraud: full refund and the trader's bond is slashed to Seat holders.
The independent Risk Engine
You are protected even from the trader. Three levels of checks run on every copied order:
- 1Per order
Scaled to your equity and allocation, leverage capped, protective stop attached.
- 2Per strategy
Breach → stop. Leverage spikes, martingale or rapid drawdown → pause new entries.
- 3Per account
Your daily loss limit, max drawdown, equity floor and one-click kill switch.
Stops and limits are best-effort: latency, gaps and venue outages can cause slippage.
Your money stays in your account
PropChange never holds your trading capital. You connect a trade-only API key — keys with withdrawal permission are rejected automatically.
For traders: earnings
Get paid every Epoch you keep your contract — Seat Fees released from escrow (75%), optional performance fees above a high-water mark, and royalties if Seats become transferable.
