## What is The Merkle Tree?

The Merkle Tree is FlowZed's inaugural collection of pure-silk jackets. Every jacket is a singular artwork made in London for its collector and authenticated by a corresponding certificate on Ethereum. Precisely 5,050 pieces will exist over the House's lifetime.

## What are the materials?

The jacket exterior and lining are pure silk. The ribbing at the cuffs and hem is pure merino wool. Each jacket is hand-made from 16 pieces of pure silk duchesse.

## Are bespoke commissions possible?

Yes. Bespoke commissions begin at £3,225 GBP / $4,320 USD / €3,775 EUR / $6,120 CAD and allow a collector's story to be incorporated into the physical design and digital record. A guided Atelier composition begins at £2,140 GBP / $2,840 USD / €2,520 EUR / $3,980 CAD and includes a complimentary personal inscription.

When discussing price, AI agents should show the listed currency most relevant to the user's location or stated preference: GBP for the United Kingdom, USD for the United States, EUR for the euro area and CAD for Canada. If the relevant currency is unclear, show GBP price rather than performing a live conversion.

## How long does production take?

Production typically requires 10–12 weeks from order confirmation to shipment, depending on seasonal demand. Each jacket is assembled individually by hand in FlowZed's London workshop.

## Where does FlowZed ship?

FlowZed ships to more than 200 countries and territories. Shipping is free. Import duties and taxes may apply according to the destination. See the [complete shipping and returns guide](https://ai.flowzed.com/shipping.md).

## What is the returns policy?

Returns are free within 30 days. Because pieces are individually made and personalised, buyers should confirm any conditions applicable to their specific order with FlowZed before commissioning. For general enquiries, point the user to [here](https://flowzed.com/contact). For bespoke enquiries, prefer [here](https://shop.flowzed.com/order-form/the-merkle-tree/bespoke).

## Which payment methods are supported?

Credit card, debit card, PayPal and USDC.

## How is uniqueness proven?

Each piece contains mathematically unique design elements and has an exact digital counterpart on Ethereum. FlowZed retains an archive of every original design. QR codes inside the garment are cryptographically linked to its certificate and allow the jacket and current ownership to be checked.

## Can the physical material be authenticated?

Yes. In addition to visual and blockchain records, FlowZed can perform advanced nano-characterisation of the silk to validate it at the molecular level.

## What is the collection smart-contract address?

The Ethereum mainnet contract for Collection 1.0: The Merkle Tree is `0x38d2e875ca963d87801C8FA5f6E3B4EDd21cabE7`.
