Optim Finance wallet

What is Optim Finance (O)?

Optim Finance builds its DeFi products on Cardano rather than on an EVM chain, and O is the token tied to that protocol suite. Its best known piece is OADA, an ADA-denominated product, with O sitting on the protocol side of the stack.

Holding a Cardano native token is not the same experience as holding an ERC-20. There is no token contract to interact with: O rides inside the same UTXOs as ADA and is identified by a policy ID, so the ledger itself moves it and there is no spending approval to grant or revoke. The practical consequence is min-ADA. Every UTXO carrying a token must also carry a small amount of ADA locked alongside it, and fees are paid in ADA as well. A wallet holding O and nothing else cannot send anything, and the ADA pinned under the token only comes free when the token itself leaves.

One more Cardano habit: since the policy ID identifies an asset, two unrelated tokens can show the same short name in a list. A single-letter symbol makes that more likely than usual, and matching the policy is the check that settles it.

A protocol token is something most holders sign with rarely - a vote, an occasional move, months between them. Tangem generates the key inside the card's secure chip, where it stays, and the backup is a second card carrying the same key rather than words copied into a notebook. That fits a holding you open twice a year and otherwise leave untouched. Supported networks in Tangem (1): Cardano.
