Shen wallet

What is Shen (SHEN)?

Shen is the reserve side of Djed, the stablecoin system on Cardano. Djed holds its peg through over-collateralisation, and SHEN is the token standing for that collateral: it is minted by putting ADA into the reserve and burned to take ADA back out, while the reserve absorbs the movement that keeps the stablecoin where it should be. Base fees charged on stablecoin activity collect in that same reserve, which is why the reserve and SHEN cannot be thought about separately.

The design puts one real constraint on holders. The protocol keeps the collateral ratio inside a band, and while the ratio sits at an edge of that band, minting or burning SHEN is unavailable until it moves back. The token remains yours and remains transferable throughout; it is the mint and redeem path that pauses, not the balance. Anyone counting on entering or leaving at a chosen moment should treat that as a property of the mechanism rather than a malfunction.

On Cardano, SHEN is a native asset rather than a contract token. It travels inside UTxOs beside ADA, so a minimum amount of ADA is always locked together with it in whatever UTxO holds it, and fees are paid in ADA.

Supported networks in Tangem (1): Cardano.

Tangem generates the private key inside the card's chip and keeps it there, and another card from the same set brings back the identical wallet if you ever need it, with a seed phrase left as a choice rather than a requirement. A reserve position you expect to leave alone is well matched to a key that lives in one drawer and a duplicate in another.
