About

Swing is a cross-chain liquidity infrastructure API that lets developers quickly build cross-chain dApps. Swing takes care of underlying infrastructure like multi-chain bridging, liquidity sourcing and routing so that developers can focus on building their application. Swing is built by a team of Silicon Valley engineers from Apple, Amazon, Linkedin and backed by Republic Capital, Arrington Capital, Avalanche, Celer, Bitcoin.com and more. Swing is the fastest way to integrate cross-chain bridges and multi-chain liquidity into your web3 project.

What should I build?

  1. Cross-chain Uniswap(Ethereum, Polygon, Fantom, BNB Chain)
  • Fork Uniswap and integrate Swing’s API to enable cross-chain token transfers(stablecoin transfers) and cross-chain swaps (any-to-any swaps)
  1. Cross-chain Arbitrage Bots
  • Integrate Swing’s API and create arbitrage bots to scalp, trade and earn profits of assets that live on multiple chains
  • Example: Let's say the HACK token exists on Polygon and Ethereum. You buy 10,000 HACK on a polygon dex and the price therefore goes up by 5%. But now, HACK is cheaper on Ethereum. So a bot can buy HACK on Ethereum for 5% less, bridge it to Polygon, then sell it on that first dex to capture the 5% gain.
  1. Cross-chain wallets
  • Integrate Swing’s API and enable wallets to perform cross-chain swaps and take deposits from any chain
  1. Cross-chain Yield Aggregators
  • Using the Swing API, build a yield aggregator that keeps track of yields on multiple chains and provides liquidity to maximize yield ROI
  1. Universal Crypto Yielder/Depositor
  • Enable users to deposit crypto on any blockchain (ie. Fantom) and earn yield or perform other DeFi transactions on another chain(ie. Polygon). Use the Swing API to automatically bridge funds over and accept crypto/stablecoins on any blockchain!
  1. Any cool idea making use of the Swing API for cross-chain liquidity!

Additionally, projects which exceed expectations will be offered bonus prizes.

Project submissions will be judged based on the following criteria:

  1. Use of the Swing API (e.g. number of endpoints, bridges, liquidity sources used)
  2. Originality/creativity/great UX
  3. Technical competence (well organized and written code)
