​

What it offers

• deposit: Deposit assets into vault, receive yield-bearing shares
• withdraw: Withdraw assets by specifying asset amount
• redeem: Withdraw by specifying share amount

​

Notes

• ERC-4626 compliant (same interface as sfrxETH, pufETH, sDAI)
• Each vault has a unique address per underlying asset + strategy combination
• Approve underlying token to vault before depositing
• Vaults are deployed via factory - no single canonical vault address
