Icosa wallet

What is Icosa (ICSA)?

Icosa is the third layer of the HEX family: HEX at the base, Hedron (HDRN) minting against HEX stakes, and ICSA sitting on top of Hedron. ICSA is not bought into existence by the protocol so much as minted by locking value into it: HDRN and ICSA itself are staked into Icosa's contracts for a chosen term, and the contracts also tie into Hedron's borrowing side. Anyone holding ICSA is usually holding it because they have positions inside those contracts, which means the wallet is a signing key for time-locked commitments rather than a place tokens pass through.

The practical details matter more than the design. On PulseChain every transaction is paid in PLS, so a wallet with ICSA and no PLS cannot move or stake anything. PulseChain is a fork of Ethereum, so addresses are byte-for-byte the same shape on both chains and a token with the same name can exist on each as an entirely separate contract with its own balance. Sending to an address you copied from an Ethereum context will not land where you expect.

Supported networks in Tangem (1): Pulsechain. Because balances are held per network and the app names the network on the outgoing transaction before the card is asked to sign, you get a chance to read it and stop. Pair that with a PLS balance in the same wallet for gas, and ICSA sits where you can act on it without extra parts.
