Why Ketju rejected Spark Savings (sUSDS)

Memo v1Published by Ketju Research

A registry memo, published verbatim and versioned. Superseded versions are recorded, never edited away. A rejection is a judgment for Ketju's client base and thesis, not a universal safety claim. Not investment, legal, tax, or compliance advice.

The memo

REJECTED AS A DUPLICATE RECORD, NOT AS A REJECTION OF sUSDS. The prior description was factually wrong: Spark's own documentation says sUSDS is a Sky product earning the Sky Savings Rate, not a Spark Savings V2 wrapper routed through the Spark Liquidity Layer. This slug and the approved-with-limits sky-lending memo name the same symbols and economic claim. Maintaining two verdicts for one instrument would double-count exposure and create contradictory monitoring. Keep this record rejected as an alias and use sky-lending as the canonical sUSDS decision. A distinct Spark V2 product such as spUSDC requires its own symbol, slug and underwriting.

What would reopen the file

  • Keep allocation at exactly 0% while the live slug maps to the Ethereum USDS and sUSDS contracts already governed by sky-lending; reopen within 5 business days only if a symbol or contract changes
  • Any recommendation, watchlist row or exposure report counting this alias above 0% fails the duplicate-allocation control
  • A replacement product reopens only after distinct symbols and contracts, a mapped yield source and control set, six months of production history, and three proposed-size entry and exit tests
