總覽
On-chain marketplaces have to reconcile two worlds. Ownership and settlement happen on a ledger, but discovery, search, pricing display and customer support still depend on fast off-chain systems that must agree with the chain at all times.
We engineer both sides together: settlement contracts and order protocols, indexers that track listings and transfers in near real time, and storefronts that make ownership, fees and royalties understandable to people who have never used a wallet.
商業應用
- 01
Digital collectibles and media
Platforms for ERC-721 and ERC-1155 assets with lazy minting, creator royalty signaling through ERC-2981, collection management, and metadata pinned to durable storage such as IPFS or Arweave.
- 02
Ticketing and access passes
Token-based tickets and memberships with issuer-defined transfer rules, resale controls, check-in verification and wallet-optional flows, so attendees can take part without any prior blockchain experience.
- 03
Licensing and digital rights
Marketplaces where tokens represent usage rights to content, data or software, with license terms referenced on-chain and enforcement logic integrated into the products that honor those licenses.
- 04
Embedded commerce
On-chain ownership features added to existing commerce platforms, with card purchases through third-party payment and on-ramp providers, embedded wallets, and fulfillment tied to existing order systems.
工程方法
- 01
Market design
We define listing types, fee and royalty handling, dispute paths and transfer restrictions, separating what the contract enforces from what platform policy governs.
- 02
Protocol selection
We decide whether to build on an established order protocol such as Seaport or write a purpose-built settlement contract, weighing audit history, flexibility and ecosystem compatibility.
- 03
Indexing and search
Event indexers and search services keep listings, ownership and prices consistent with chain state, handling reorganizations and metadata refreshes so stale results never reach users.
- 04
Storefront and wallet experience
Interfaces present fees, royalties and ownership plainly, support signature-based listings that avoid unnecessary gas costs, and offer embedded wallets for first-time users.
- 05
Hardening and launch
Contract testing and audit support, hooks for bot and wash-trading detection, rate limiting and monitoring prepare the marketplace for real traffic and adversarial behavior.

決策者關心的問題
Can royalties be enforced on-chain?
Partially. ERC-2981 signals royalty terms but does not force payment on every transfer. Stronger enforcement requires transfer restrictions or marketplace allowlists, which reduce composability. We explain these trade-offs and implement the model that matches your creators' expectations and your platform policy.
Do buyers need a crypto wallet?
Not necessarily. Embedded wallets tied to email or passkey sign-in, combined with card payments through third-party providers, let users acquire and hold items without managing seed phrases. Experienced users can still connect their own wallets if they prefer.
Will you operate the marketplace for us?
No. We engineer and hand over the software, documentation and runbooks, and we can train your team to run them. Operation, payment processing, customer relationships and regulatory responsibilities remain with your organization and the licensed payment or on-ramp providers you engage.
