How to Stake Polygon (POL) With a Hardware Wallet

Polygon PoS is secured by validators who lock up POL. Holders who do not run a validator can delegate POL to one and receive a share of its rewards: proportional to the delegated stake, minus the validator's commission, as Polygon's documentation puts it. Polygon states that staked funds are locked in a contract on the Ethereum mainnet and that no validator holds custody over delegator tokens.

That location is the detail most people miss. Polygon's delegation guide says all staking transactions take place on Ethereum and that funds for staking need to be on the main Ethereum network. For a hardware wallet this means:

• The token you delegate is POL on Ethereum. POL held on the Polygon network has to be bridged to Ethereum first.
• The gas coin is ETH. Delegating, claiming, restaking, unbonding and withdrawing are all Ethereum transactions.
• The device signs with its Ethereum account. Polygon network support on the device matters for holding POL there, not for the delegation.

The migration from MATIC to POL went live on 4 September 2024, and Polygon describes POL as the successor to MATIC as the native gas and staking token of Polygon PoS, at a ratio of 1:1.

• MATIC that was already staked was upgraded to POL with no action required, according to Polygon's support article on the migration.
• MATIC still held on Ethereum can be migrated 1:1 through the Polygon Portal, in a transaction signed on the device. Polygon's guide recommends migrating and delegating POL, and adds that delegated MATIC earns its rewards in POL.
• On the Polygon network the switch was automatic, though some wallets may still show the old symbol.

In-app staking is convenient but narrower: the app decides which validators it shows. Ledger's announcement of March 2026, for example, describes a validator node operated by Meria and reached through Yield.xyz. For other brands, check the vendor's own documentation. How the routes compare across networks is covered in hardware wallets for staking.

Of the 41 models in our catalog, 31 list the Polygon network, and all 31 support Ethereum in the manufacturer's own app. For 28 of them Polygon is handled in that app too: the Ledger, Trezor, OneKey, Tangem, SafePal and Ellipal ranges, plus CoolWallet Pro, Cryptnox, Cypherock X1 and NGRAVE Zero. BitBox02, BitBox02 Nova and Keystone 3 Pro reach Polygon through a third-party wallet such as Rabby or MetaMask.

Listing the network is not the same as in-app staking. For delegation, what counts is that the device can sign Ethereum contract transactions and reach the dashboard through one of the routes above. The staking ranking compares models on this, and how to check supported coins shows how to confirm a token for your exact model.

The sequence uses the staking dashboard with the device connected through a browser wallet or WalletConnect.

1. Get POL and ETH onto the device's Ethereum account. If your POL is on the Polygon network, bridge it to Ethereum first. That is a separate process with its own fees; see Polygon's bridge documentation for how long it takes.
2. Open the dashboard from a saved bookmark. Staking front ends are copied by phishing sites. Do not follow links from ads or messages.
3. Connect the hardware account. Select the account that belongs to the device and make sure the wallet is set to Ethereum mainnet.
4. Pick a validator. The criteria are covered below.
5. Send the approval and confirm it on the device. Polygon's guide describes delegation as two transactions: the first approves the request, the second deposits the approved amount. Set the approval to the amount you intend to stake, and check the token, the amount and the network on the device.
6. Send the delegation itself. Confirm this second transaction on the device and wait for it to be included.
7. Verify the result. The delegation should appear under your account on the dashboard, and both transactions in a block explorer.

Staking is not a one-time signature. Each later action is its own Ethereum transaction, confirmed on the device and paid for in ETH.

At the time of writing, per Polygon's documentation, the unbonding period is 80 checkpoints of approximately 30 minutes each. Ledger's documentation rounds this to roughly two days, and Polygon notes that congestion can delay checkpoints. The figure is a protocol parameter and can change, so read it on the dashboard before you unbond.

Rewards do not compound by themselves: they accumulate until you claim or restake them, and each of those costs gas. On a small stake the Ethereum fee can exceed the reward being collected.

What the screen shows depends on the device. The first transaction is a standard token approval. Whether the staking calls appear in readable form or as raw data varies; Polygon's guide notes that on a Ledger, permission to call contracts has to be turned on. Our guide to blind signing risks explains what that setting means.

Polygon's guide leaves the choice to the delegator's own research. These are the points to compare in the dashboard's validator list:

• Commission. Each validator sets its own rate and, per Polygon's documentation, there is no upper limit. Validators can update the rate, so check it again from time to time.
• Checkpoint performance. Validators have to sign checkpoints regularly; missed signatures reduce their performance score, and a validator can be removed from the active set for poor performance. This record is the closest thing to an uptime figure.
• Status. Polygon states that you can delegate to any validator except those that are offline.

The device ensures that nothing is delegated, moved or withdrawn without a confirmation on its screen. The risks below belong to staking itself.

• Slashing. Polygon's delegation guide does not set out slashing terms for delegators. Polygon Labs' risk disclosure for its own liquid staking token does say that validators may be penalised for malicious behaviour or protocol violations and that this risk passes through to holders. Treat the question as open and read the current documentation before delegating.
• Contract risk. Delegated POL sits in staking contracts on Ethereum. A flaw in them would affect the stake however it was signed.
• Waiting time. During unbonding the tokens cannot be sold or moved, whatever the price does.
• Front-end risk. A fake dashboard can present an approval for an attacker's address. The checks are the same as for any dapp; see using a hardware wallet with DeFi.

With liquid staking you deposit POL with a protocol and receive a token that represents the staked position. The device signs it like any other DeFi deposit, but the arrangement differs from direct delegation: the protocol chooses the validators, a further set of smart contracts stands between you and the stake, and the token's market price can differ from the POL behind it. Some apps present liquid staking simply as "staking", so check which of the two you are signing.

• The dashboard shows a zero POL balance. The tokens are on the Polygon network, or the wallet is connected to a different account. Staking uses POL on Ethereum.
• The balance shows MATIC, not POL. The tokens on Ethereum have not been migrated. Polygon recommends migrating before delegating.
• A transaction fails or stays pending. There is not enough ETH for gas, or the fee was set too low for current conditions.
• The device rejects the transaction. It cannot decode the contract call and the setting that allows contract data is off. Confirm you are on the genuine dashboard before changing it.
• Rewards cannot be claimed. Fewer than 2 POL have accumulated.
• The stake has not come back after unbonding. Either the unbonding period is still running or the final claim transaction has not been sent.
