Wizard: Mint → Vault → Root → Claim Package
One line per allocation: `wallet,amount` or `wallet,amount,index` (token units converted by mint decimals).
On-chain safe mode auto-selects the next unused index per wallet for this distributor to prevent claim-status collisions.
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.
Generated values appear below and also prefill Distributor setup + claim sections.
Grape Distributor Program Setup
Program: GCLMhBGsDMHbxYyayzZyDY85cF89XNGgEhss4GXd9cHkInitialize distributor once, then rotate roots as claims change. Root must be 32-byte hex.New claim campaigns for the same mint reuse this distributor/vault. Publish a new root + manifest per campaign, or use a new mint for isolated vaults.
Local timezone input. Converted to unix timestamps automatically.Funding helper: transfer tokens from your connected wallet ATA into the distributor vault.

Human-readable amount; converted using mint decimals.

Clawback helper: directly withdraws distributor vault tokens to your connected-wallet ATA using the distributor authority.
Claim Tokens From Distributor
Connected wallet is used as claimant signer automatically. Claim eligibility (index/amount/proof) comes from your claim package or claim manifest.
Governance realm/program are sourced from Quick Wizard or claim JSON.Manual mode: proof nodes are one 32-byte hex string per line. Amount uses raw base units.
Optional rent reclaim helper. Works only if on-chain program supports `close_claim_status` (typically after claim window end). Uses the current claim index field.
