It is also necessary to: * Select the network on which the NFT contract has been deployed * Add a brief task description * Include a useful link that will be associated with the description text (i.e. Opensea Collection page link)

E.g. Require users to hold a specific NFT to complete the campaign

**Provide Liquidity:** With our “Provide Liquidity” task, you can monitor liquidity deposits without effort. Again the information needed are just a few: * The pool contract address * The dollar amount users should deposit * The number of days users can’t withdraw * Network, Task Description, Website URL For example, you can require users to deposit 1000$ for 30 days with a few clicks.

E.g., Deposit 1000$ for 30 days

**Track on-chain events:** With Tide, it's possible to track any on-chain event. For example, derivate protocols can ask users to open 10X leverage positions. The “Track on-chain event” is the task for monitoring interactions with any event associated with your dApp smart contracts, and it’s even possible to specify event parameters. From a technical side, the only information needed on Tide to monitor general on-chain actions are: * The contract address * The associated event you want to track * Optionally, you can add parameters to specify details related to the selected event * Network, Task Description, Website URL

E.g. Deposit 99 or more USDC in a Pool

**Minimum Token Balance:** Require users to hold a minimum balance of a specific token to participate in a campaign. The only fields to fill out are: * ERC-20 token contract address * Minimum token balance users need to hold * Network

E.g. Hold at least 100 USDC

**Minimum number of transactions in a protocol:** Require users to perform a minimum amount of transactions with a specific smart contract The necessary information are : * Smart contract address * Minimum transaction count * Network, Task Description, Website URL

E.g. Perform at least 10 transactions in a protocol

**Track advanced on-chain events:** With the advanced on-chain events features, it’s possible to add time constraints to general on-chain tasks. For example, lending protocols could easily require users to deposit funds in a pool and not withdraw for a month. You can check the information to fill on Tide to implement this task in the picture below:
