Steps
Browse markets and find an offer
Open the Canopy terminal at https://canopy.trade and select a market from the left-hand panel. Scan the SELL side of the order book for offers at prices you find attractive. Each row shows the remaining size and ask price at a glance.
Open the offer detail panel
Click the offer row you want to fill. The Offer Detail panel opens on the right side of the terminal, showing the full offer terms: total size, filled amount, remaining available size, price, expiry, settlement type (spot or forward), unlock time (if forward), and buyer restriction (if private).
Enter the amount you want to buy
In the Buy Amount field, type the quantity of asset tokens you want to purchase. You can enter any amount from the minimum fill size up to the total remaining offer size. The interface calculates and displays the exact quote token cost as you type.
Review the required quote amount
Confirm the Quote Required figure shown beneath the buy amount field. This number is calculated from the offer’s on-chain price applied to your requested fill size. It represents the base cost before protocol fees. The Total Cost (including fee) is also displayed.
Set your slippage tolerances
The Canopy fill form exposes three slippage parameters that protect you from unexpected outcomes:
The UI pre-fills conservative defaults based on current market conditions. You can tighten or loosen these values before submitting. For most fills at the quoted price, the defaults are sufficient.
| Parameter | Purpose |
|---|---|
| Max Quote Debited | The maximum total quote tokens debited from your wallet (cost + fee + any transfer taxes). The fill reverts if your total outlay would exceed this value. |
| Min Assets Received | The minimum asset tokens you must receive. The fill reverts if the delivered amount would fall below this value. |
| Min Seller Proceeds | The minimum quote tokens the seller must receive net of any transfer fees. The fill reverts if the seller would receive less than this amount. |
Approve quote token spending
If you have not previously approved the venue to spend your quote token (e.g., USDC), click Approve and confirm the approval transaction in your wallet. This is a one-time approval per quote token — future fills in the same quote token skip this step.
Click "Fill Offer" and confirm in your wallet
Click Fill Offer. Your wallet will show a transaction confirmation prompt with the contract call details and estimated gas fee. Review the information and click Confirm to broadcast the transaction to Robinhood Chain.
Receive your assets or claim tokens
Once the transaction confirms, the outcome depends on the offer’s settlement type:
- Spot offer — the asset tokens arrive in your connected wallet immediately upon confirmation. You can verify the balance in your wallet or on the block explorer.
- Forward offer — ERC-20 claim tokens arrive in your connected wallet. These tokens represent your fully collateralized, deferred position and become redeemable for the underlying asset after the offer’s unlock time. Track them under the My Claims tab in the terminal.
Partial Fills
You are never required to fill an entire offer. Enter any amount up to the remaining offer size, and only that portion of the seller’s collateral is exchanged. The unfilled remainder stays in the order book at the original price and remains available to you or any other eligible buyer.Private Offers
If an offer has a buyer restriction, only the designated wallet address can fill it. In the order book, restricted offers display a lock icon. If your connected wallet does not match the restriction, the offer row will appear greyed out and the Fill Offer button will remain disabled — the protocol enforces this check on-chain, not just in the UI.
Tips and Notes
Claim tokens received from forward fills are standard ERC-20 tokens. You can hold them in your wallet, transfer them to another address, or add them to your wallet’s token watchlist using the contract address shown in the Series Details panel. Regardless of who holds the claim token at the unlock time, the holder is entitled to redeem it for the underlying escrowed asset.
