StableStock

StableStock ProShares UltraShort Silver (sZSL) is a token tracking silver, backed by dedicated collateral.

Each token tracks one troy ounce of silver and is a collateral-backed contractual exposure rather than a direct claim on the issuer.

Qualified investors can mint and redeem directly with StableStock after completing KYC, and holders have a contractual right to redeem.

sZSL is native to BNB Chain as an ERC-20 token.
