Goliath Slingshot

Goliath Slingshot is the DeFi interface for Goliath Testnet. It is now organized into four modules:

• Swap: token swaps and liquidity pools

• Bridge: cross-chain transfers between Ethereum Sepolia and Goliath Testnet

• Migrate: stake on Sepolia and migrate through an automated flow

• Yield: liquid staking on Goliath via stXCN

Slingshot App: https://slingshot.goliath.net/
