What is Synthetix (SNX)?

SNX started life under a different name: the project launched as Havven, and the token was renamed when the protocol became Synthetix. That history still shows up in old links, indexes and API identifiers that call the token "havven", so the odd label is not a sign of a different asset. The ticker you are holding is SNX, and there has been no swap or new contract for holders to migrate through because of the rename.

What the token does is more specific than "governance". SNX is the collateral that backs the protocol. A holder who stakes it locks it in the Synthetix contracts and mints sUSD against it, taking on a share of the system's debt; the staked SNX is then not a free balance, it is held by the protocol until the debt is repaid and the position is unstaked. SNX that arrived through the staking program sits in an escrow contract with a vesting schedule and is not transferable until it vests. So a wallet may show less SNX than a holder "owns" in the wider sense, and that is normal: only unlocked, unescrowed SNX is a spendable balance.

SNX is an ERC-20 whose home is Ethereum mainnet, where gas is paid in ETH. SNX on rollups such as Optimism and Base is a bridged representation of the mainnet token, distinct from it on the ledger even though the ticker matches. In Tangem each of these is its own line: ERC-20 SNX on Ethereum and bridged SNX on Optimism are two entries with two balances, and when you send, you are choosing the line, so the network is a decision you make rather than something that happens to you. Supported networks in Tangem (7): Ethereum, Base, Optimism, BNB Smart Chain, Avalanche, Polygon POS, Fantom. For a token that has a home chain plus several bridged twins, that separation is the reason it belongs in a wallet like this.
