Creating Claims
How to define transfer constraints and create a claim
Navigate to /create or click "Create Claim" in the header.
Step 1: Fill the form
Claim message
A description of what this claim is about (e.g., "Donated to community pool Q1 2024"). Must be 10–1000 characters.
Token information
| Field | Description |
|---|---|
| Chain | Ethereum, Optimism, BNB Chain, Polygon, Base, Arbitrum, or Scroll |
| Token Type | ERC-20, ERC-721, or ERC-1155 |
| Prover Role | Sender — the prover sent the tokens. Recipient — the prover received the tokens |
| Token Address | The token contract address. Validated automatically — shows token name and symbol if found |
| Counterparty Address | The other party's address or ENS name (e.g., vitalik.eth). If the prover is sender, this is the recipient. If the prover is recipient, this is the sender |
Constraints (optional)
| Field | Description |
|---|---|
| Min / Max Amount | Range for total transfer amount. 0 = no constraint |
| Min / Max Count | Range for number of transfers. E.g., "at least 3" ensures multiple transactions |
| Start Date | Only include transfers after this date |
| End Date | Only include transfers before this date (required) |
Step 2: Fetch transfers
Click "Fetch Transfers". The app queries the blockchain for token transfers matching your constraints and displays them in a scrollable preview.
A claim can include up to 5,000 transfers. A single proof can cover up to 50 transfers from one wallet.
- Toggle "My Transfers" (when wallet connected) to filter to your address
- Changing token, chain, counterparty, or date fields resets the preview
- If no transfers found, you cannot proceed
Step 3: Create the claim
Click "Create Claim". The app sorts transfers by timestamp, hashes them, builds a merkle tree, stores the claim with the merkle root, and redirects to the home page.
The claim is now public — anyone can view its transfers and generate proofs against it.
