Mint a marketplace

Marmalade on Kadena provides the complete infrastructure to launch and run game-changing NFT marketplaces. Unlike other markets, Marmalade offers 100% on-chain transactions, high-quality provenance, low gas fees, and shared ownership that can span platforms. You’ll never have to slow down to ask: Is it safe? Will it scale? Will my marketplace support what’s next? We take care of all of that for you so you can focus on your offering, audience, and revenue.

They are building on Marmalade

A new kind of NFT marketplace

Marmalade is built on Kadena’s innovative blockchain infrastructure, providing the security of Bitcoin with virtually free gas (transaction fees), unparalleled throughput, and fractional ownership.

Kadena makes Marmalade possible.

How it works:

No-cost transactions

We leverage Kadena’s pioneering Crypto Gas Stations to allow sellers to eliminate all transaction fees for their customers, thus removing a key barrier to mass participation in the NFT market.

Resilience with energy efficiency

Proof-of-Work (PoW) provides superior security as compared to other protocols. Kadena’s innovative multi-chain architecture runs on PoW to deliver speed, scale, and energy efficiency previously thought unachievable. So the higher the TPS (Transactions per Second) on the platform, the more energy efficient it becomes.

Artifact storage

Kadena continually scales to higher TPS (Transactions per Second) as more chains are added to its network. More chain means more low-cost storage and data provisioning, enabling entire NFTs – including their rich metadata and contracts – to be minted on-chain.

Haber Content Integrity (HCI)

As invented by blockchain co-inventor Dr. Stuart Haber, Marmalade NFTs mint on-chain with rich manifests, capturing all references and artifacts in Merkle trees that identify items as well as their complete version history.

Uniqueness enforcement

Like so many things in Marmalade, one feature powers another. Rich Merkle-verified manifests and on-chain artifacts create NFT hash-based addresses that are unique, self-verifying, and make it impossible to mint a duplicate item.

Superior custody

Safety isn't just about valuation; it's also about reliable chain-of-custody. When ownership is hard to steal, long-term NFT value grows. Marmalade ledgers use Pact’s multi-sig support (where multiple keys are required to authorize transactions) to unlock programmable, fractional ownership. This means innovative, multi-owner structures can be programmed directly on chain with each owner receiving a key to manage only their own rights for any given item.

Marketplace standards

NFT standards in Ethereum cannot enforce marketplace requirements like royalties. Only Marmalade offers genuine on-chain NFT sales, priced in any token, that are enforced no matter what exchange they're offered on.

Pact for NFT

A very different contract language

Pact isn’t like other smart contract protocols. Designed to be readable by non-developers, Pact has been battle-tested in production applications for over two years. It delivers the first indexable, multi-chain NFT standard, delivering all the benefits of ERC-1155 as well as fractional ownership.

Ahead of the curve

Pact already contains all the features that other platforms say they will eventually develop, including full Formal Verification of code, error messaging, contract upgradability, multi-sig, and support for interoperability. Pact facilitates complex transactional logic with an ideal combination of authorization, data management, and workflow functionality.

A new era for NFT minting

Decentralized infrastructure is the highway for digital value, with on-chain onramps and offramps. But it only works when interop between platforms is safe and low cost. Marmalade allows elements to trade on different exchanges with liquidity pools supporting unique incentives and cash flows spanning multiple exchanges.

The end of copy-paste

Today on EVM platforms, the simplest contract requires reams of copy-pasted code. The result is every contract must be audited line-by-line, every time. It’s confusing and slow to work with. And it’s unsafe. Copy-paste prevents interop (transactions across platforms), making every project an island, trapping NFT minters in a single market, and preventing fractionals from the benefits of placement on multiple exchanges.

One NFT, many markets

Pact, Kadena’s smart contract language, was built for interop, making it safe to call other contracts. A ledger holding liquidity pools can now be used safely by multiple exchanges, allowing a single PolyFungible NFT ledger to service the entire market.

New standards for new opportunities

Because ERC ledger standards (20, 721, 1155) don’t include records of where and how transactions were executed, each market is effectively a black box. With Marmalade, marketplaces expose standard interfaces, allowing tokens to safely transact across platforms – and even create new forms of hybrid markets.
