Swing + Velora Delta Bring Gasless Cross-Chain Execution
Give your users seamless cross-chain trading without requiring gas tokens.
If you build cross-chain products you already face two support-ticket magnets:
“I’m out of native gas on that chain.”
“Front-running bots just stole half my slippage.”
With Delta, the new intents engine from Velora (formerly ParaSwap), both headaches disappear. Swing has integrated Delta directly into our router, so every dApp that uses the Swing SDK or Widget can now offer gas-free and MEV-minimised swaps on an initial set of high-liquidity networks: Ethereum, Optimism and Base.
What exactly is Velora Delta?
Delta is Velora’s next-gen alternative to the Augustus router that powered ParaSwap’s first $110 B in on-chain volume across 4.4 M+ wallets.
A user signs a lightweight intent (not a full transaction).
The intent is broadcast to Portikus, a permissionless network of “agents.”
Agents bid to fill the trade; the winning agent pays the upfront gas, with the cost seamlessly covered by the trade's output tokens. This means users don't need to hold native gas tokens to trade.
Delta has processed over$1.2B in volume across 43k+ transactions, all without requiring users to hold native gas tokens and with no exposure to mempool MEV.
How Swing plugs in
Swing already aggregates bridges, DEXs and routers behind the Swing API. Wiring Delta into our pathfinder delivers three concrete wins to every swap() call:
Gas abstraction - trade without holding native gas. Network fees are paid using a portion of the swap's output tokens.
MEV immunity - orders never touch the public mempool.
Price competition - the Portikus auction often beats classic SOR quotes by a few basis points.
No new contracts, no exotic parameters – Swing selects Delta automatically whenever it produces the best route.
Where Galaxy Exchange fits
Galaxy – the retail interface built on Swing – now pipes eligible orders through Delta on Ethereum, Optimism and Base by default. For integrators embedding the Swing Widget, that means:
• No “insufficient gas” errors → higher conversion.
• No mempool exposure → cleaner trade receipts.
• A security layer that resonates with institutions (Velora’s $110 B pedigree + Swing’s audited bridge set).
Prefer to own the UX? Use the Swing SDK directly and surface $0 gas required in your own interface.
Where Gas-Free Swaps Create User Value
• Games onboarding players who only hold stables.
• Fiat ramps offering “withdraw to any chain” without dust balances.
• Perp protocols enabling one-click collateral migration between L2s.
• Galaxy itself – becoming the zero-gas entry point for everyday traders.
Roadmap
• More chains – zkSync, Scroll and Solana intents are in active testing.
• Limit/stop orders – Delta’s off-chain auction is perfect for trigger-based execution; we’re adding it to Swing’s Order API.
• Agent onboarding – Velora is opening additional solver slots; infra teams can apply.
Call to builders
Edge-case gas bugs and MEV headaches cost you users. Plug into Swing, let Velora Delta handle execution, and ship cross-chain UX that feels like a single network.
