# Unity Ecosystem Wallet Permissions

> Ecosystem Wallet Documentation for Sequence's Unity SDK.

### Parameters

* **Chain:** The chain this signer is allowed to interact with.
* **Target:** The contract address this signer is allowed to interact with.
* **Deadline:** The deadline for this permission as a UTC timestamp in milliseconds.
* **Value Limit:** The maximum total amount of native tokens this signer can send.
* **Parameter Rules:** The rules that define how this signer is allowed to interact with the target contract.

### Single contract permission

```csharp theme={null}
Chain chain = Chain.TestnetAbitrumSepolia;
Address contractAddress = new Address("0x33985d320809E26274a72E03268c8a29927Bc6dA");
BigInteger deadline = new BigInteger(DateTimeOffset.UtcNow.ToUnixTimeSeconds() * 1000 + 1000 * 60 * 5000);
BigInteger valueLimit = 0;

IPermissions permissions = new ContractPermissions(chain, contractAddress, deadline, valueLimit);
```

### Permissions with multiple targets

```csharp theme={null}
Chain chain = Chain.TestnetAbitrumSepolia;
Address contractAddress1 = new Address("0x7F5c764cBc14f9669B88837ca1490cCa17c31607");
Address contractAddress2 = new Address("0x33985d320809E26274a72E03268c8a29927Bc6dA");

IPermissions permissions = new Permissions(chain,
    new ContractPermissions(contractAddress1, deadline, valueLimit),
    new ContractPermissions(contractAddress2, deadline, valueLimit));
```

### Parameter rules

```csharp theme={null}
var rule = new ParameterRule
{
    cumulative = false,
    operation = (int)ParameterOperation.equal,
    value = Array.Empty<byte>(),
    offset = new BigInt(0),
    mask = Array.Empty<byte>(),
};

ContractPermissions permissions = new ContractPermission(...);
permissions.AddRule(rule);
```
