# Fund Markets (Liquidity Providers)

Liquidity Providers supply capital to a market’s **pool** and earn yield as borrowers repay. Programmatically, funding is the **pool-adapter** flow: deposit for shares, and a two-step delayed withdrawal.

***

### Discover pools

```bash
# pools your arena exposes
curl -H "X-Arena-Key: $ARENA_KEY" "$ARENAS_API/lending/pools"
# an account's positions, shares, and pending withdrawals
curl -H "X-Arena-Key: $ARENA_KEY" "$ARENAS_API/lending/pools/list/$ACCOUNT"
```

Use a pool where the item exposes an `adapterInfo.address` — that adapter is the contract you interact with (not the pool share-token address).

***

### Deposit

```mermaid

```

1. `approve` the **asset token** to the adapter address.
2. `deposit` into the adapter to receive pool shares.

Before submitting, check the adapter’s `cap` vs `totalDeposited` (`cap = 0` means unlimited) and confirm the pool phase currently allows deposits.

***

### Withdraw (two-step, delayed)

Withdrawal is always two on-chain steps, even when the delay is zero:

1. `createWithdrawRequest` — locks your shares (approve the **pool share** token to the adapter first). One active request per LP; **not cancellable**.
2. `executeWithdrawRequest` — after `withdrawDelay` elapses, the same wallet executes and receives assets.

See [Supply](/atomica/financing-markets/supply.md) and [Withdraw](/atomica/financing-markets/withdraw.md) for the mechanics.

### How your capital is used

Deposited liquidity is offered to borrowers as **intents** — priced offers filled cheapest-first when a borrower draws down. Your yield tracks the interest borrowers pay on the intents your pool fills. See [Intents & Liquidity](/atomica/intents-and-liquidity.md).

***

### Boosted yield via Aave

LPs can amplify returns by supplying Aave collateral, delegating its borrowing power, and routing the borrowed liquidity into Atomica pools to earn the spread. See the [Aave Market](/arenas/aave-market.md) strategy and [Credit Delegation](/arenas/credit-delegation.md).

### After every write

Poll `GET /provisioning-sync/last-synced-blocks` until your transaction’s block is indexed, then refetch `pools/list/:account` so balances and pending-withdrawal state are current.
