Cross-chain swaps without destination gas headaches.
Destination Gas Abstraction is a key benefit of using the SwapKit SDK — a routing capability that eliminates the need for users to pre-fund destination gas.
With SwapKit’s Destination Gas Abstraction, developers can keep users in-app, simplify swap flows, and boost completion rates.
What is Destination Gas Abstraction?
Most people are familiar with Account Abstraction (AA) gas abstraction:
- Works on one chain.
- Lets users pay gas with ERC-20s or via sponsorship.
Destination Gas Abstraction is different.
- Works across chains.
- Users pay gas only on the source chain.
- The destination chain’s network fees are handled inside the route economics and shown in the swap quote.
The result: one signature, one gas source, cross-chain finality.
Why It Matters (UX First)
Requiring destination gas kills conversions: users leave your app, hunt down a token they don’t hold, and often never come back.
With SwapKit Destination Gas Abstraction:
- The quote includes all fees (source + destination).
- Users sign once and pay gas only on the originating chain.
- Swaps finalize on the destination chain without extra steps.
Impact:
- Higher completion rates.
- Fewer “stuck at the finish line” tickets.
- A seamless day-one experience for users bridging into new chains.
How to Design It
Treat gas abstraction as a route capability, not a product toggle.
Best practice design pattern:
- Show: “You receive (all fees included).”
- In the review step, add: “Destination network fees are included in this route.”
- Disclose time-to-finality: “Est. 2–4 min.”
- If conditions change mid-flow, failover: “Switching to an alternate route to complete your swap.”
No extra screens — just clear, lightweight disclosure.
Routing Neutrality with SwapKit
SwapKit is a multi-provider router:
- Compares venues on net output, reliability, and settle time.
- Picks the route that wins — sometimes it’s a destination-gas-abstracted path, sometimes it’s a traditional route.
- Provides automatic fallback if a venue degrades or halts.
For developers, this means:
- One integration.
- Neutral routing across THORChain, Maya Protocol, Chainflip, NEAR Intents, and more.
- No need to hard-code vendors or manage fee quirks.
Builder Checklist
- ✅ Keep users in-app — don’t send them for destination gas.
- ✅ Enable multiple cross-chain venues, let the router decide.
- ✅ Use simple disclosure: all fees included.
- ✅ Track outcomes: completion rate, spreads after fees, time-to-finality, fallback rates.
Metrics That Matter
With SwapKit Destination Gas Abstraction, you can measure:
- Uplift in completion rate on cross-chain routes.
- Effective spread after all fees vs alternatives.
- Time-to-finality (sign → final).
- Fallback frequency and reasons.
- Drop in support tickets mentioning “no gas on destination.”
The Takeaway
Destination Gas Abstraction turns “I can’t finish — no gas there” into “Done.”
Keep it provider-neutral and route-driven:
- Enable multiple venues.
- Let routing choose the best path.
- Disclose fees clearly in one line.
With SwapKit, your cross-chain swaps feel like one network — even as you expand to 30+ chains and beyond.
