# Maple

> Deposit USDC or USDT into Maple's Syrup vaults on Ethereum for syrupUSDC or syrupUSDT, with a queued exit.

The Maple integration deposits USDC or USDT on Ethereum into Maple's Syrup vaults, an ERC-4626 lending product. You receive syrupUSDC or syrupUSDT, an ERC-4626 share whose redemption value rises as the underlying loans pay interest.

## Availability

| Network | Input token | Position token |
| - | - | - |
| Ethereum | USDC | syrupUSDC |
| Ethereum | USDT | syrupUSDT |

List the markets enabled for your project with [`GET /v1/yields`](/api-reference/YieldsController_getYields) filtered by `providers=maple`.

## Entering

Deposits route through Maple's Syrup Router rather than a direct ERC-4626 `deposit` call. Every Syrup pool requires a lender authorization: if your address is not already an approved Syrup lender, the enter flow needs an `authorization` argument (a signed bitmap, deadline, and signature) before the router will accept the deposit. An optional `permit` argument (an EIP-2612 permit signature) can combine the token approval and the deposit into fewer steps.

<Note>
  Maple's pools are non-transferable, permissioned lending positions: the authorization requirement is Maple's own lender allowlist, not a yield.xyz control.
</Note>

## Exiting

Exiting calls `requestRedeem` on the pool, which queues your shares for withdrawal; it does not return USDC or USDT immediately. Maple's withdrawal manager processes the queue on a first-in, first-out basis as loans mature and liquidity becomes available. When your request clears, the underlying asset is sent directly to your address; there is no separate claim step and no pending action to submit.

<Warning>
  Queued withdrawals can take time depending on pool liquidity. A second `requestRedeem` for a position already in the queue fails; check your position before submitting another exit.
</Warning>

## Rewards and position

Lending yield compounds into the syrup token's share price automatically. Maple also runs a separate Drips incentive program that accrues alongside your deposit; it has no manual claim action in this integration.
