The interface uses an injected browser wallet (MetaMask, Rabby, or any EIP-1193 provider). If no injected wallet is detected, the connect button will not be offered a provider to open.

• Install the wallet extension and unlock it before loading the page.
• If the network chip reads Not connected, the wallet is locked or the site lacks permission.
• A wrong-network state blocks commitments. Switch network from the wallet button rather than reloading.

Commitment reverts are specific. The contract rejects under these conditions, and the reason is visible in the wallet or on the explorer:

Underpaid

Value sent does not equal claim units × claim price.

Sold out

You asked for more units than remain uncommitted.

Funding closed

The deadline has passed, or funding is not open.

Wrong state

The project is not in the FUNDING state.

Because the price is fixed per unit, a commitment is deterministic: there is no slippage, and a pending transaction cannot be filled at a different price.

• No weight to vote with. A vote requires claim units in that project, held at the moment the snapshot was taken. Buying claims after evidence was submitted does not grant weight for that milestone.
• Already voted. One address gets one vote per milestone, and it cannot be changed.
• Review closed. Voting is only possible inside the review window. Once it elapses, anyone may settle.

• Listing requires an approval. The market contract has to be approved as an operator on the claim token before it can move your units into escrow.
• Units are escrowed when listed. A listed balance disappears from your wallet. Cancel the listing to reclaim unsold units.
• Wrong payment amount. A fill must send exactly units × ask price. Partial fills are supported; overpaying is rejected.
• Transfers frozen. During a dispute or after a default, claims in that project cannot be transferred. Listings in a frozen project cannot be filled.

Refunds become available only when a project reaches CANCELLED or DEFAULTED. The payout is pro-rata against your current claim balance, and your claims are burned on refund, so a refund cannot be claimed twice. Nothing needs to be requested in advance.

Amounts are stored on-chain in wei and converted for display, so a rounding difference of one unit in the last displayed decimal place is expected. The chain value is authoritative.

Figures marked as demonstration data are seeded for the prototype and do not reflect any real project, production run or transaction.

Most issues are visible on the block explorer: a reverted transaction records its reason there. If a value on this interface disagrees with the explorer, the explorer is correct.
