Step 1: Buy 40OP, USDC, VAULT

Purchase 40OP, USDC, VAULT on Bybit, BINGX, or MEXC. Choose the Optimism network for withdrawal to avoid bridging fees. Confirm the network before completing the transfer.

Step 2: Set Up a Wallet

Step 3: Get Optimism for Gas

Buy a small amount of Optimism's native token to pay transaction fees — usually $1–10 worth is sufficient for several transactions.

Step 4: Connect to 40 Acres

Visit the official 40 Acres app. Bookmark the URL directly. Never click links from DMs, social media, or email — phishing sites mimic real protocols exactly.

Step 5: Approve and Deposit

Approve the token spend in your wallet, then confirm the deposit transaction. Yield begins accruing in the next block after confirmation.
