Check the Stake MATIC (opens in a new tab) user guide.
Staking MATIC on Ethereum, your minimum amount is 1 MATIC.
Staking MATIC on Polygon, there is no minimum amount.
Staking MATIC on Ethereum, there is no maximum amount.
Staking MATIC on Polygon, your maximum amount is limited by the crosschain staking pool capacity. You will see the capacity while staking.
MATIC staking happens on Ethereum. You can stake/unstake any MATIC amount at once. Ethereum gas fee applies. Also, when unstaking, you receive your MATIC and rewards after the 3–4 days unbonding period.
MATIC crosschain staking happens on Polygon. You may have to stake/unstake your MATIC in portions, as you’re doing it via a crosschain staking pool, which may not have the amount you need at the moment. Also, an additional fee applies. However, there is no unbonding period, so when unstaking you receive your MATIC and rewards instantly.
If you staked on Ethereum, you’ll receive your MATIC and rewards after the unbonding period of 80+ epochs; typically, it takes 3–4 days.
If you staked on Polygon via the crosschain staking pool, you’ll receive your MATIC and rewards instantly.
aMATICb is not actively supported anymore. We recommend you switch your aMATICb for ankrMATIC (ex-aMATICc) (opens in a new tab).
ankrMATIC (ex-aMATICc) is a reward-bearing token, meaning its quantity stays the same from the moment of staking. Instead, it appreciates in value in relation to MATIC, so the redemption price of 1 ankrMATIC will grow over time because of reward accumulation.
aMATICb rewards arrive in your wallet every rebase, which is daily. A propos, aMATICb is not actively supported anymore. We recommend you switch your aMATICb for ankrMATIC (ex-aMATICc) (opens in a new tab).
ankrMATIC rewards are built into the token. Effectively, your rewards accumulate daily as ankrMATIC grows in value relative to MATIC.
Ankr takes a 5% technical service fee from the staking reward to cover for the provided services and operations.
Remember that when staking on Ethereum, the user pays a gas fee (typically, 0.0005 ETH), and when staking on Polygon, the user may pay a small dynamic fee.
Also, remember that when unstaking on Polygon, the user pays a technical service fee of 0.5% from the unstaking amount.
Your stake continues to accumulate rewards until the moment you have received them.
The only risk for stakers is missing out on rewards during any time a validator they staked with is slashed. Slashing is a protocol-level penalty associated with a validator failure if it validates an invalid transaction or goes offline. The delegated staked MATIC is not slashed — slashing impacts only the self-stake of the validator. Ankr only delegates to trusted and reputable validator nodes to avoid any validator that would act maliciously.
You can trade them in the listed liquidity pools on ANKR DeFi:
You can also use your Liquid Staking tokens to:
Add liquidity on DEXs (opens in a new tab) and earn from commissions taken when users swap tokens, using the liquidity pool you're a part of.
Yield farm (opens in a new tab) and earn additional rewards in the form of liquidity pool tokens and further farm them.
Put your tokens in a vault (opens in a new tab) and automatically earn additional rewards in the form of one of both assets from the pair.
ankrMATIC (ex-aMATICc) only changes in value, which is why the amount of ankrMATIC you get when staking is calculated by the formula
stake * exchange_ratio. The exchange ratio is calculated like this:
totals_supply_of_ankrmatic / (total_staked_matic + total_rewards_for_staked_matic - total_unstaked_ankrmatic).
Yes, you can use Ledger Nano cold wallets through MetaMask. Visit the Ledger's guide on connecting Ledger through MetaMask (opens in a new tab).
Yes — there is a user guide (opens in a new tab).
Yes, if you want to integrate Ankr Liquid Staking into your product, read Liquid Staking Metrics (opens in a new tab).
ankrMATIC (ex-aMATICc) supports staking and unstaking on Polygon.
aMATICb only supports Ethereum. You can bridge your aMATICb to Ethereum and then unstake it.
