Olympus wallet

What is Olympus (OHM)?

One protocol, three tokens

OHM is the base token of Olympus. Every OHM is backed by a treasury of on-chain assets, and the protocol manages OHM's supply and liquidity through fixed rules. Under Range Bound Stability, the treasury buys OHM below a lower band and sells it above an upper one. The protocol also owns its own trading liquidity, and Cooler Loans let holders borrow against their position instead of selling it.

Holders deal with three related tokens. Plain OHM never changes balance on its own. sOHM is staked OHM, and its balance grows through rebases. gOHM wraps staked OHM into a non-rebasing token whose OHM value follows an index, and it is the collateral used in Cooler Loans. If you find OHM in an old wallet, check which contract it is. The protocol moved to a v2 OHM contract, and v1 tokens have to go through the official migrator before they can be used.

OHM is also issued on several networks. Each has its own contract, while an Ethereum-style address is identical on all of them.

Supported networks in Tangem (4): Arbitrum One, Base, Ethereum, Optimism.

Tangem keeps a separate OHM balance for every network, and the confirmation screen names the network so you can check it against what the receiving side expects before the card signs. That check is still yours to make. OHM spread across this many chains is easier to track when each chain has its own line, which is reason enough to hold it on the card.
