Stader MaticX wallet

What is Stader MaticX (MATICX)?

MaticX represents a position in Polygon's staking system, held through Stader. You hand over the network's native token, the protocol delegates it to validators, and you get MaticX back - a transferable claim you can hold, move or use elsewhere while the underlying stake stays delegated.

Like its Ethereum sibling, MaticX keeps a constant token count and lets the redemption rate against the underlying token do the moving, so a balance that has not budged in months is normal rather than a sign something has gone wrong. Unstaking is not instant either: it goes through Polygon's unbonding period before the underlying tokens are claimable, which is a scheduling matter to know about before you need the funds.

Where MaticX gets awkward is location. The staking contracts sit on Ethereum, while a bridged form of the token also circulates on Polygon PoS and on Manta Pacific. Same ticker, same address of yours, entirely separate balances, and the one you hold determines what you can do with it and what you pay fees in - ETH on Ethereum, the network coin on Polygon, and Manta's gas on Manta. Worth confirming which version an exchange or contract is actually handing you.

Supported networks in Tangem (3): Ethereum, Manta Pacific, Polygon POS.

In the Tangem app each of those sits under its own network with its own figure, and the network a transfer is leaving on is stated on the screen you approve before tapping the card. Since the recipient address looks identical across EVM chains, that check is yours to make - and a wallet that never merges the three into one number makes it an easy one.
