Mint & Claim

The two operations on the NFTs page.

Mint

1. Open NFTs.
2. Pick a tier you can afford.
3. Click Mint LitShard (or LitCore / LitGod).
4. Sign. The contract:
   • deducts the points cost from your PointsSystem total,
   • mints one NFT to your wallet,
   • emits a Mint event.

The new NFT appears in Your NFTs instantly.

Mint failures

Cause	What it means
Insufficient points	Your total points are below the tier cost. Earn more before retrying.
Max supply reached	The tier is sold out. Try a different tier.
User rejected	You declined the wallet popup.

Claim

1. Open NFTs.
2. Scroll to Your NFTs.
3. Click Claim All or per-tier Claim.
4. Sign. The contract pays the accumulated zkLTC + USDC + LDEX since your last claim per held NFT.

The success card lists each token + amount.

Claim cooldown

Claim is once per day per tier. The contract tracks lastClaimDay:

uint256 today = block.timestamp / 86400;
require(today > lastClaimDay[user][tier], "Already claimed today");

If you try to claim again on the same day the tx reverts. Skipping days is fine — the next claim pays for all skipped days at once.

Multi-tier claim

If you hold multiple tiers, you can call Claim All which loops through and claims each in one tx. Saves gas vs three separate claims.

Pending rewards display

The card shows "Pending: X zkLTC + Y USDC + Z LDEX" computed live from getPendingRewards(user). This number grows every block until you claim.

Claim every 1–2 days to keep gas overhead low. Claiming every block is wasteful.
