Question 1

What is SWAPS?

Accepted Answer

SWAPS is a trade engine for tokenized marketplaces. Collectors connect a wallet, choose cards they want, and see trades they can approve from their own perspective: give this, get that. SWAPS handles the heavy lifting behind the scenes.

Question 2

What problem does SWAPS solve?

Accepted Answer

SWAPS solves the double coincidence of wants -- the requirement that two parties must each have exactly what the other wants at the same time. In markets for unique assets like NFTs, collectibles, and tokenized real-world assets, this leaves valuable inventory stuck. SWAPS opens up more trades from the same marketplace activity.

Question 3

How does SWAPS find trades?

Accepted Answer

SWAPS evaluates what collectors own, what they want, and what is currently available across the marketplace. It then surfaces high-quality give/get opportunities that can be approved with a clear user action.

Question 4

What keeps trade opportunities current?

Accepted Answer

SWAPS keeps marketplace state up to date as inventory, wants, approvals, and completed trades change. That means the widget can keep showing relevant opportunities without asking users to understand the infrastructure.

Question 5

How fast is trade discovery?

Accepted Answer

Trade discovery is designed for real-time marketplace experiences. The system keeps current market state ready so valuable opportunities can be surfaced quickly, even as inventory and wants change.

Question 6

How do I integrate SWAPS?

Accepted Answer

A current V2 integration uses a server key to bulk load inventory and wants, a publishable key plus HMAC user headers for widget/browser calls, available swaps and For You reads for the user experience, accept to prepare the wallet approval transaction, broadcast reporting after the wallet sends it, and readiness/webhooks for launch operations.

Question 7

How long does integration take?

Accepted Answer

Most pilot integrations are bounded by inventory quality, wallet signing UX, and webhook handling rather than by the API surface itself. The supported launch path is REST plus the embeddable V2 widget, with examples and dedicated integration support.

Question 8

Do I need to change my existing smart contracts?

Accepted Answer

No marketplace contract migration is required for the V2 integration. Users approve or delegate the specific asset required for the selected trade, the asset stays in the user wallet until settlement, and SWAPS cannot move it without the required wallet approval.

Question 9

What do webhook events look like?

Accepted Answer

SWAPS sends signed webhook notifications for state changes such as new opportunities, invalidations, completions, and failures. Payloads include public trade state, wallet addresses, and asset metadata, with internal scoring inputs and private diagnostics removed.

Question 10

What do end users see?

Accepted Answer

That depends entirely on you. SWAPS is white-label infrastructure -- your users never see the SWAPS brand. They interact with your marketplace UI and your transaction flow. SWAPS surfaces trade recommendations through your API, and you present them however fits your product.

Question 11

Is the experience customizable?

Accepted Answer

You can choose the embeddable widget theme and layout with data-theme and data-layout. If you need full visual control, build your own marketplace UI against the REST API and signed widget/browser flows.

Question 12

Does the widget support light and dark themes?

Accepted Answer

Yes. The embeddable widget supports light and dark themes. Set data-theme to light or dark on the script tag; omitted values default to light.

Question 13

What is the custody model?

Accepted Answer

SWAPS is non-custodial. We never hold or escrow user assets. Assets remain in users' wallets until settlement, and each user must approve or delegate the asset required for the selected trade before it can move.

Question 14

How does atomic settlement work?

Accepted Answer

Once every required approval is ready, settlement is submitted onchain as an all-or-nothing transfer flow. Either the trade completes or assets remain with their current owners.

Question 15

Can SWAPS move assets without user consent?

Accepted Answer

No. SWAPS cannot move any asset without explicit wallet approval from the owner. The settlement smart contracts enforce this at the protocol level. If a required approval is missing or revoked, the trade cannot settle. There is no admin override.

Question 16

What happens if a trade fails onchain?

Accepted Answer

All settlements are atomic. If any transfer within the trade fails -- due to revoked approval, insufficient gas, or any other reason -- the entire transaction reverts. No user loses any asset. The failed trade is logged, webhooks are sent, and SWAPS keeps looking for available alternatives.

Question 17

What blockchains does SWAPS support?

Accepted Answer

Current mounted V2 accept paths support Ethereum ERC-721 and Solana standard NFTs. Solana pNFT support is deployment-gated, and Metaplex Core assets must pass a live compatibility check before a user is asked to sign. ERC-1155 is legacy surface area, not the default mounted V2 widget accept path.

Question 18

What types of assets work with SWAPS?

Accepted Answer

SWAPS is strongest today for tokenized unique collector assets with concrete asset IDs and specific target wants: NFTs, gaming items, digital collectibles, and trading cards. Other tokenized asset categories require partner-side eligibility, valuation, and transfer-rule checks before concrete inventory and wants are submitted.

Question 19

Do assets need to be onchain already?

Accepted Answer

Assets need to be represented as tokens on a supported blockchain for SWAPS-managed atomic settlement. If your assets are off-chain today, you can still use SWAPS for trade discovery and handle settlement through your own process.

Question 20

What is the pricing model?

Accepted Answer

SWAPS offers tiered plans designed for teams at every stage, from development and testing through enterprise-scale production. Contact us at info@swapsapi.com for current pricing and to discuss which tier fits your use case.

Question 21

Who is SWAPS built for?

Accepted Answer

SWAPS is built for marketplace developers and platform operators who need to unlock liquidity for unique or semi-fungible digital assets. This includes NFT marketplaces, gaming platforms with item economies, collectibles trading platforms, and any marketplace handling tokenized real-world assets.

Question 22

How does SWAPS increase marketplace revenue?

Accepted Answer

By discovering trades that bilateral matching cannot find, SWAPS unlocks liquidity and increases trade volume. More completed trades mean more transaction fees for the marketplace. Reduced inventory staleness lowers user churn, and coordinated trading drives user engagement and retention.
