How can I be sure it's safe to deposit?

Use the same rule that works for any DeFi service: don't just trust a claim — test it with a small amount first.

Make a small deposit, then withdraw it. If that little amount goes in and comes back out correctly, you've proven the whole round-trip works for you — your wallet, the network, the contract, and the withdrawal. After that, you can deposit a larger amount with confidence.

It costs only a bit of gas, and it's the most honest check there is: you're not trusting words, you're watching your own funds move and come back. (A practical self-test — it doesn't replace the bigger picture in "Is it safe? Is it audited?")
