What is Icosa (ETH) (ICSA)?

ICSA comes out of the Hedron corner of the HEX ecosystem on Ethereum - a stack of contracts layered on top of one another, where each token is minted by locking or staking the one below it. Icosa is the layer above Hedron: HDRN goes into the Icosa contract, and ICSA is what the contract issues against it. ICSA itself can be staked in the same contract, and the protocol also has a role for HEX Stake Instances, the NFTs that represent individual HEX stakes.

What that means practically is that a holding here is usually a commitment, not a balance you touch. Positions in these contracts run on timers and are managed by calling the contract directly; the loose ICSA in your wallet is only the free part. Anything staked shows up as contract state rather than as a wallet number, so do not assume a smaller wallet figure means something went missing.

Two details worth carrying with you. ICSA is an ordinary ERC-20 on Ethereum, so every action - a transfer, a stake, an end-stake - costs ETH, and these contract calls are not cheap ones. And the ecosystem attracts copies: tickers and names get reused, and the only thing that identifies real ICSA is the contract your wallet has registered, not the symbol on a list.

Because the interesting moments in a position like this are months or years apart, the key that controls it should be the kind you do not handle in between. Tangem generates it inside the card's chip and it never leaves; a second identical card, kept somewhere else, is the backup, and a seed phrase is yours to add only if you want one. For a holding you deliberately leave alone, that is the setup that stays out of your way. Supported networks in Tangem (1): Ethereum.
