Functions

Signature	Notes
`createCampaign(string title, string description, uint256 goal, address claimKey) → uint256`	Creates a campaign owned by msg.sender. Emits CampaignCreated.
`donate(uint256 campaignId) payable`	Adds msg.value to the campaign. Reverts if closed or zero. Emits Donated.
`claim(uint256 campaignId, address recipient, uint256 amount, bytes signature)`	Pays amount to recipient given a valid claim-key signature. Emits Claimed.
`setActive(uint256 campaignId, bool active)`	Creator only. Opens or closes donations. Emits CampaignStatusChanged.
`rotateClaimKey(uint256 campaignId, address newClaimKey)`	Creator only. Replaces the claim key and bumps the nonce. Emits ClaimKeyRotated.
`claimDigest(uint256 campaignId, address recipient, uint256 amount, uint256 nonce) → bytes32`	EIP-712 digest the claim key must sign.
`getCampaign(uint256 campaignId) → Campaign`	Full campaign struct.
`getCampaigns(uint256 offset, uint256 limit) → (uint256[] ids, Campaign[] page)`	Paginated list, newest first.
`campaignCount() → uint256`	Number of campaigns ever created.
`nonces(uint256 campaignId) → uint256`	Current claim nonce.

Events

Signature	Notes
`CampaignCreated(uint256 indexed campaignId, address indexed creator, string title, uint256 goal)`	New campaign.
`Donated(uint256 indexed campaignId, uint256 amount)`	Donation received.
`Claimed(uint256 indexed campaignId, uint256 amount)`	Funds released. Recipient intentionally omitted.
`CampaignStatusChanged(uint256 indexed campaignId, bool active)`	Opened or closed.
`ClaimKeyRotated(uint256 indexed campaignId)`	Claim key replaced.

Integrating

Everything the site does is a plain contract call; no backend, indexer or API key is involved. To list campaigns, call getCampaigns(0, n). To watch activity, subscribe to the events above. To build an alternative claim client, read nonces(id), sign the typed data with the claim key, and call claim from any funded wallet.
