Spark discloses live X Layer spUSDC deployment and unexercised allocation route
The Ledger · · Ketju Research
Affects: Spark Liquidity Layer (protocol) · Spark Savings (sUSDS) (protocol)
What happened
Spark published a deployment record for live X Layer spUSDC and segregated Ethereum and X Layer custody systems, with dated deployment and deposit evidence.
What changed
The new vault introduces an administered savings rate and a configured CCTP v2 route to Ethereum legacy sUSDC. Its yield liability accrues independently of the investment position.
What did not change
Existing Ethereum spUSDC custody and controller were not migrated. The disclosure does not establish US eligibility, insurance or Ketju approval.
Confirmed
- The record identifies X Layer spUSDC proxy 0xf90E63079D97a0A1f479b2b168457F420CAFf6ba and documents deposits by external users.
- Governance controls administration; Phoenix Labs operational actors can allocate and set VSR through an AdministeredAgent.
- The October 4 official checks report that assets remained in the vault and the allocation and bridge route had not been exercised.
- The record reports 1,049.22 USDC of accrued VSR obligations not yet backed by earned yield at its October 4 snapshot.
- The stated governance acceptance deadline is March 23, 2027, with orderly wind-down required if acceptance is not obtained.
Still open
- Production completion of the end-to-end allocation and return route.
- Spark governance acceptance and subsequent public recognition record.
- Advisor-access eligibility and proposed-size entry and exit performance.
- Whether later operations have funded the accrued yield obligations.
What it means for an advisor
- Review the Spark Liquidity Layer authority and per-chain custody analysis against the disclosed segregated deployment.
- Review the Spark Savings alias memo before classifying X Layer spUSDC as an existing approved savings exposure; its contracts and administered liability are distinct.
- Add bridge-return reliability, yield funding and acceptance-deadline monitoring to the diligence file.
