The deal
What you do
Claim a Greenfield Testnet Tutorial NFT on zkBridge, then retweet PolyhedraZK’s post to earn loyalty points. The NFT’s metadata is stored on BNB Greenfield and only a specific contract address is valid.
Why it's 4/10 risk
- The source references galxe-testnet/zkbridge and specific links, but no funding pool size or contract details are provided here.
- No audit reports are mentioned for the NFT minting flow or related smart contracts in the provided text.
- This is a testnet tutorial NFT credential, so secondary-market liquidity (if any) is likely low or non-existent.

Before You Participate
- Your minted/claimed NFT may be invalid if it does not use the exact contract address 0x13D23d867e73aF912Adf5d5bd47915261eFa28F2.
- Loyalty points are tied to the exact retweet link; retweeting a different post (or after the claim window) may not qualify.
- You may complete the steps outside the claimable period (ending 2023/08/10 00:00) and lose rewards.
- Tutorial metadata dependency: the NFT metadata is said to be stored on BNB Greenfield, so missing steps in the described tutorial flow can impact qualification.
✓ Who it's for
- Users who want a low-capital, task-based testnet NFT credential
- People comfortable following tutorial links and completing a mint/retweet flow
- Builders curious about BNB Greenfield storage for messages and NFT metadata
✗ Not for
- Users who want a guaranteed token reward or fixed monetary payout
- Users who cannot verify the exact NFT contract address or follow social tasks
