Spark wallet

What is Spark (SPK)?

Behind the SPK ticker sits Spark, a lending and liquidity protocol that grew out of the Sky (formerly MakerDAO) ecosystem. Spark takes stablecoin capital from Sky's reserves and places it across DeFi lending markets, centralized venues and tokenized real-world assets, and runs SparkLend, a lending market where USDS and DAI are borrowed at rates set by governance rather than by utilization. Its savings products, sUSDS and sUSDC, are separate tokens with their own mechanics; SPK is not one of them.

SPK itself is the protocol's governance token. Holding it gives a say in Spark's parameters and it can be locked in Spark's own staking module, where it collects Spark Points. It is a plain ERC-20 with a fixed balance: nothing accrues in the wallet, no rebase, no wrapping needed to hold it. Transfers and any contract interaction are paid in ETH, so a little ETH next to SPK is the practical minimum.

Two things to check before you send

The name has history. Flare's network token was called "Spark" before it became FLR, and a Bitcoin scaling layer also goes by Spark and has no token at all. If a listing says Spark, confirm it is the Sky-ecosystem SPK before you act on it. Part of the SPK supply was distributed through airdrops, so many holders received it rather than bought it and never checked which contract they hold; verifying the token contract in a block explorer once is worth the minute.

A governance token is the kind of asset that sits still for months and is signed with only when a vote or a staking action comes up. That pattern suits Tangem well: the private key is created inside the card's chip and never leaves it, a second card carries the same key as a backup, and a seed phrase is an option you can add rather than a piece of paper you must guard. For SPK that mostly waits, a card in a safe place is the whole setup.
