Every FlowZed jacket is backed by an NFT that depicts its exact design. The garment itself features stochastic elements - including tree arrangement, monogram tiling, and token ID placement - that are mathematically unique. FlowZed maintains an internal archive of every original piece for verification purposes, to complement the publicly available record in the NFT depictions.
Each jacket carries inherent visual traits, including:• The number of trees on each panel (back, front, sleeves)• The presence or absence of visible Ethereum smart contract code• Leaf colour (Sakura, Rainbow, Autumn, or Winter)• Background colour (Black, Navy, Royal Purple, Burgundy or Emerald)• The rare appearance of our marmoset mascot (Blue, Silver or Gold)• Any bespoke detailsThese traits are visible both in the garment’s design and in its backing token.
All collectors may choose the background colour of their jacket while redeeming their physical piece, at the same time as selecting their size.FlowZed bespoke personalisation is the highest offering for those collectors who seek to inscribe their own presence both on-chain and into the garment itself. The presence of bespoke details forms additional traits, as applicable.
Yes, for those collectors who seek a deeper level of exclusivity and creative expression, FlowZed offers bespoke configuration of pieces in The Merkle Tree. Discover more about bespoke here.
Collector-chosen traits - namely, size, background colour and any bespoke features - are stored directly on-chain along with the redemption status using Chain Fusion technology. This ensures that your jacket’s final physical characteristics are preserved with cryptographic permanence.
Access to The Merkle Tree collection is restricted to holders of a ZedPass or to those who already own a FlowZed jacket. ZedPass holders are able to mint pieces directly during the collection’s public phase. Ownership is not open to the general public.
A ZedPass is a soulbound token - a non-transferable NFT that grants the holder the right to mint jackets from The Merkle Tree collection. ZedPasses are not sold. They are earned through nomination and serve as a cryptographic invite to access the FlowZed network.
A ZedPass Nomination token allows an existing FlowZed collector to nominate another individual for entry into the network.When a Nomination token is sent to a new address, it automatically converts into a ZedPass - granting the recipient access to mint a jacket. Each new collector receives ZedPass Nomination tokens upon minting their item from The Merkle Tree.
Pieces in the Merkle Tree can be purchased using Ether, the native token of the Ethereum blockchain, or Bitcoin. In all cases, the NFT proving ownership and authenticity is issued and stored on Ethereum.Value stability is achieved by pegging the mint fee against the price of gold, determined by the XAUt/ETH spot price on Uniswap, and further verified against the ETH/USD, USD/XAU and BTC/ETH currency and commodity spot prices.
Each FlowZed jacket contains embedded QR codes, cryptographically linked to the original token on Ethereum. Scanning the code allows verification of both the jacket’s legitimacy and its current owner’s on-chain wallet address, using public tools such as etherscan signature verification.For ultimate assurance, FlowZed can perform advanced nano-characterisation of the silk itself, validating authenticity at the molecular level.
Once you mint a token from The Merkle Tree collection, you gain access to our token-gated collectors’ zone. There, you can select your size and base colour, confirm your delivery address, and initiate the redemption of your physical jacket. Redemption is strictly single-use.
Each NFT grants a single redemption of its corresponding physical jacket. Once redeemed, the redemption status is set permanently on-chain, ensuring absolute integrity and preventing repeat claims.
No. Collectors of NFTs from The Merkle Tree can redeem their physical jacket at no additional cost. This includes the fee for international shipping and import duties. FlowZed reserves the right to make changes at any time.
FlowZed ships globally, to over 200 countries and territories. Please see the full list of countries here to confirm whether you are able to receive a physical jacket in your location.
Each jacket is individually assembled by hand in our London workshop. From redemption confirmation to shipment, production typically requires 8–12 weeks, depending on seasonal demand.
