# Contratos Inteligentes (Smart Contracts)

Actualmente, los contratos inteligentes se dividen en tres: **ImpactMarket, CommunityFactory** e **Community**.

## ImpactMarket <a href="#impactmarket" id="impactmarket"></a>

Su única función es aceptar nuevas comunidades. Esto será reemplazado por un mecanismo (ya en desarrollo) con votación para nuevas comunidades.

## CommunityFactory <a href="#communityfactory" id="communityfactory"></a>

Su única función es implementar nuevos contratos comunitarios. Un contrato por comunidad. Este contrato está controlado por impactMarket.

## Community <a href="#community" id="community"></a>

Este es el contrato que utilizan las comunidades. Existe un contrato por comunidad, que permite donaciones individuales a cada una de ellas.

A continuación se enumeran los métodos públicos que se pueden llamar para obtener información sobre el contrato.

```
// When the beneficiary can claim again (timestamp)mapping(address => uint256) public cooldown;// What was the last interval when the user claim.// This is used to calculate the next intervalmapping(address => uint256) public lastInterval;// How much has the beneficiary claimed so far.mapping(address => uint256) public claimed;// In what state is the beneficiary (enum BeneficiaryState {NONE, Valid, Locked, Removed})mapping(address => BeneficiaryState) public beneficiaries;​// community amount per claim (in cUSD)uint256 public claimAmount;// community base interval (we have been using 1 day or 1 week) (in seconds)uint256 public baseInterval;// community increment interval (in seconds)uint256 public incrementInterval;// community maximun claim per beneficiary (in cUSD)uint256 public maxClaim;​// if the community was migrated, will have here the addressaddress public previousCommunityContract;// impactMarket contract addressaddress public impactMarketAddress;// cUSD contract addressaddress public cUSDAddress;
```

### Functions <a href="#functions" id="functions"></a>

**Nota importante:** para integraciones externas, cuando un gerente intenta agregar una dirección como gerente o beneficiario, esa dirección debe registrarse primero en el sistema, de lo contrario, aparecerá un error mencionado en la sección agregar beneficiario. Para evitar esto, use endpoint / api / user / auth. Para obtener más información, consulte la sección [API](https://docs.impactmarket.com/v/espanol/developers/api).
