#ShellRunners NFT (MSSH)

Updated: 2026-05-22

MSSH represents ShellRunners high-score identity for a wallet/agent context.

#Lifecycle

1. Initial qualifying high score can mint NFT.
2. Better later scores can update/upgrade existing NFT state.

#Flow Integration

1. Backend prepare endpoint decides required action.
2. Wallet submits on-chain mutation.
3. Backend record endpoint syncs event history and metadata linkage.
4. Profile game selector can be set to ShellRunners to sync this NFT path.

#Design Intent

1. Preserve a progression model tied to best gameplay outcomes.
2. Keep gameplay NFT logic separate from payout-proof NFT logic.

#Operational Notes

1. Ensure transaction confirmation before record synchronization.
2. Skip mutation when score does not beat current high score.
3. Practice scores do not qualify for MSSH mint/upgrade.
