A buyer may want an item but lack cash on hand, another holder may be willing to move if they receive a different asset, and an inventory manager might want to rebalance across collections rather than accept a single cash sale. These scenarios leave assets sitting idle, lower fill rates, and reduce marketplace revenue opportunities.
The effect compounds at scale: more listings don’t necessarily mean more completions. Liquidity becomes patchy, discovery becomes noisy, and users who would transact under the right combination of outcomes end up waiting—or leaving. Marketplaces need a way to turn fragmented interest into clear, executable outcomes without forcing a full rebuild of their product.
SWAPS runs behind your product and creates trades.
Your product keeps each user’s inventory current via API or webhook (have) and the user declares what they want (want). We return execution‑ready proposals for the user to review and execute atomically inside your product. No staff brokering or handoffs required. Just movement.
The pain we remove
- Stalled inventory: long‑tail items sit because a single 1:1 moment rarely exists.
- Dead ends for motivated users: your current flow can’t show a viable path from have to want.
- Manual brokering: DMs, discounts, and one‑off exceptions don’t scale or audit well.
- Flat fill rates: more listings and search don’t fix misaligned intent.
SWAPS exists to turn conditional intent into clear, user‑approvable outcomes—with the assets users already hold.
What SWAPS is
- A coordination service, not a marketplace. You own the front end; SWAPS powers the trade creation behind it.
- API‑first. Your product sends have and want per user; you request proposals on demand.
- Execution‑ready outputs. Results arrive packaged for atomic (all‑or‑nothing) execution and audit.
- Tenant‑isolated and authenticated. Keys you manage; scopes, throttles, and structured logging by default.
- No custody. We don’t custody assets; your platform remains the execution surface.
This approach increases the chance that every participant gets something they value without introducing new trust assumptions.
(SWAPS is not a pricing engine, a prediction tool, or a replacement for your core marketplace. We don’t disclose how proposals are produced; you get outcomes—period.)
How it fits your stack (user‑driven, no ops in the loop)
- Inventory in. Your product keeps each user’s inventory current via API or webhook.
- Intent in. In your UI, the user selects what they want. You pass have/want to SWAPS.
- Proposals out. SWAPS returns a compact set of execution‑ready options.
- User executes atomically. The user approves in your product; the trade completes as a single action.
Why it works for your business
- More completions without a cash leg—users act using what they already hold.
- Movement in the long tail—acceptable outcomes are surfaced, not hunted manually.
- Operational simplicity—no staff brokering step; proposals are ready for user decision and system execution.
- A clean revenue lever—coordination is work; you can charge for it and tie it to completed outcomes.
Results to measure
- Inventory movement in segments that underperform under pure 1:1 flows.
- Completions from non‑cash users (acting via assets already held).
- User time‑to‑decision from proposal to settle.
- Operational load (manual exceptions reduced).
- Coordination‑fee performance (if you monetize).
Outcomes depend on data quality and user participation. Start small, measure, then scale deliberately.
Trust, security, and operations
- Isolation & auth. Tenant‑isolated data; API keys with scopes; keys hashed at rest.
- Rate & abuse controls. Per‑key and per‑IP throttles; optional gating for public flows.
- Environment gating. Sensitive features run only when you enable them.
- Observability. Structured logs and request/response IDs for audit and incident response.
Performance
Product‑grade latency for interactive requests; background/batch discovery for heavier workloads; stateless at the request layer for horizontal scale.
Who benefits most
- Marketplaces with deep catalogs where the long tail drags on fill rates.
- Platforms with engaged holders locked in assets they’d rather transform than sell to cash.
- Teams that want a systemized, auditable coordination lane without inserting staff approvals.
Bottom line
SWAPS takes a user’s have and want, creates execution‑ready trade proposals, and lets the user execute atomically so movement happens without a cash leg.
