# POL (MATIC) staking

> Delegate POL to a Polygon validator from Ethereum, with a required validator address on enter and exit.

POL (MATIC) native staking delegates POL held on Ethereum to a Polygon validator. This is native, delegated staking: you choose the validator.

## Yields

| Yield ID | Staking type | Provider | Validator selection |
| - | - | - | - |
| `ethereum-matic-native-staking` | Native | Polygon validators | Required |

## Key facts

| | |
| - | - |
| Network ID | `ethereum` |
| Staked token | POL (MATIC) |
| Minimum | 1 POL |
| Warmup | None |
| Unbonding / cooldown | 2 days |
| Rewards | Claimed manually |

## Enter and exit

Enter takes `amount` (required, minimum 1) and `validatorAddress` (required), plus an optional `inputToken`. Exit takes `amount` and `validatorAddress`, both required, for the validator being undelegated from.

## Managing the position

| Action | What it does |
| - | - |
| `WITHDRAW` | Claims the unbonded balance once the 2-day cooldown has passed. |
| `CLAIM_REWARDS` | Claims accrued delegation rewards. |
