# Trigger Integrations

Triggers are the events that qualify users for rewards. Fuul supports 30+ pre-built integrations with leading DeFi protocols, plus the ability to create custom triggers for any onchain or offchain action.

## Integration types

Triggers work differently depending on the data source and timing:

| Type                    | How it works                                      | Timing                    | Best for                                                    |
| ----------------------- | ------------------------------------------------- | ------------------------- | ----------------------------------------------------------- |
| **Native integrations** | Pre-built connectors for popular protocols        | Scheduled (usually daily) | Supported DeFi protocols (AMMs, lending, staking)           |
| **Custom onchain**      | Monitor any smart contract event or function call | Real-time                 | Swaps, mints, deposits, or any onchain action               |
| **Custom offchain**     | Receive events via the Fuul API or CSV upload     | Real-time                 | Sign-ups, purchases, social actions, or any off-chain event |
| **Token holders**       | Track balances of any token (ERC-20, NFT, SPL)    | Scheduled (usually daily) | Holding rewards, governance token programs                  |

## Which integration should I use?

| Your use case                                              | Recommended integration                     |
| ---------------------------------------------------------- | ------------------------------------------- |
| Action is atomic and irreversible (swaps, mints)           | **Custom onchain**                          |
| Value is time-dependent (deposits, LP positions, holdings) | **Native integration** or **Token holders** |
| Supported protocol (Uniswap, Morpho, etc.)                 | **Native integration** (pre-built, best UX) |
| You track actions in your own backend                      | **Custom offchain** (API events)            |
| You need daily aggregated data from a partner              | **Custom offchain** (scheduled API)         |

## Pre-built integrations

Fuul natively supports the following categories of protocols. Each is described in detail in the pages below.

## Supported networks

Fuul supports triggers across **35+ networks** including Ethereum, Arbitrum, Base, Optimism, Polygon, Solana, HyperEVM, Berachain, Monad, Stellar, Stable, and many more.

{% hint style="warning" %}
**Tracking a network is not the same as paying out on it.** Two networks are currently tracking-only:

* **Stellar** — a `stellar_address` can accept referral codes, be attributed conversions, rank on leaderboards, and earn points, but cannot receive an onchain token payout. See [Stellar signatures](/developer-guide/tracking-referrals-in-your-app.md#stellar-signatures).
* **Stable** (chain 988) — selectable for token holder triggers and in the audiences token balance segment builder. No V2 contracts are deployed there, so wallet connection, budget deposits, and claims are unavailable.

For programs paying tokens on these networks, reward in points or collect a payout address on a supported chain. The networks listed in [EVM Claiming](/developer-guide/claiming-onchain-rewards/evm.md) are the payout-enabled set.

We're continually expanding support for new triggers and protocols. If you're interested in a specific use case that isn't listed, reach out at <ecosystem@fuul.xyz>.
