Zap into a Pendle Yield Token pool with ETH on Arbitrum

This use case allows a user to enter a Pendle pool to speculate on or hedge against yield from a liquid restaking token. Try this route → Route mechanics This is a two-step bundle that:
  • Swap native ETH to weETH using odos protocol on Arbitrum
  • Deposit weETH into Pendle SY protocol to receive the Pendle Yield Token position
