ProSwap Trading Interface
Multi-chain swap dApp with chain abstraction and gasless approvals via ERC-4337.
ProSwap’s trader-facing interface routes swaps across six EVM networks with unified wallet flows, account-abstraction-powered approvals, and subgraph-backed positions - built for institutional traffic patterns.

Representative technologies from the delivery-not an exhaustive inventory of every dependency or internal tool.
Challenge
The protocol needed one coherent UX across chains without duplicating components per network - while preserving gasless approval paths and sub-second quote freshness during volatile blocks.
Approach
We shipped a Next.js front end with viem and wagmi, chain-abstraction hooks, paymaster integration for sponsored approvals, and The Graph for pool and position state with staleness guards on reads.
Outcome
Placeholder programme narrative - verify before publish. Stated headline: $1.2B in trading volume routed through the interface across 6 chains with 99.7% transaction success rate.
