Golem wallet

What is Golem (GLM)?

Golem rents out computing power. Machines with spare capacity advertise it on a peer-to-peer marketplace, requestors send work to be computed, and GLM is the money that changes hands between them - a requestor bids GLM for a task, a provider is paid GLM for running it.

One piece of history matters more than anything else for a holder. The original token was GNT, and it was replaced by GLM at a one-to-one rate through a migration contract. They are two different ERC-20 contracts, and old GNT sitting in a wallet is not GLM: it will not show up as the current token and is not what the network settles in. If you are recovering a long-dormant wallet, check which of the two you are actually looking at.

GLM also exists on Polygon as a bridged version of the Ethereum token, which is the cheaper place for the small, frequent payments the marketplace generates. The two balances are entirely separate, and the coin that pays the fee differs: ETH on Ethereum, POL on Polygon. Because an address looks the same on both, the network is the thing to verify rather than the address string.

Tangem shows each of these as its own line with its own balance and states the network a transfer is leaving on in the confirmation you approve before tapping the card. When one token trades on two chains under one ticker, reading that line before signing is the habit worth keeping, and a wallet that puts it in front of you is the sensible place for GLM.
