13. Grape Distributor Quick Wizard

Wizard: Mint → Vault → Root → Claim Package

Index Strategy

On-chain safe mode auto-selects the next unused index per wallet for this distributor to prevent claim-status collisions.

Mint Address

Distributor and vault are deterministic per mint. Reusing the same mint reuses the same distributor/vault; use a new mint for a separate distributor instance.

Claimant Wallet (optional, defaults to connected wallet)

Governance Realm (optional, include for claim + DAO deposit)

Governance Program ID (optional)

Governance Program Version (optional)

Allocations

Generated values appear below and also prefill Distributor setup + claim sections.
