Other claim: overcollateralised vault dollar with a peg stability module; no central issuer. Collateral of $2,422.3m on 27 Oct 2026 (USDD data API): TRX and staked-TRX vault collateral $1,154.8m (47.7%); the Smart Allocator's Spark savings USDS $725.2m (29.9%), held as sUSDS (on-chain read 28 Oct 2026), so looked through to USDS, itself mixed; the allocator's other $494.7m (20.4%) in USDT lending and vault positions (Spark Savings, Aave, JustLend, Morpho), recorded as 'other' (on-chain loans, not held tokens, as for USDe and Sky); USDT in the peg modules and the USDT-A vault $47.6m (2.0%). No class is over half, so mixed. Until 28 Oct the Spark USDS position was read as lending, which made 'other' a bare majority (decision 2026-10-27-reserves-2-1: keep the strict-majority rule, refreshed as the split moves). Issuer data only, hence low. sUSDD, the staked version, earns the savings rate; USDD itself pays nothing.

Accessed 28 Oct 2026. eth_call through a public RPC at block 26287784 (28 Oct 2026, 00:57 UTC). sUSDS contract 0xa3931d71877C0E7a3148CB7Eb4463524FEc27fbD (address from Spark's sUSDS token docs): the operator holds 650.81m sUSDS, worth 725.21m USDS by the contract's convertToAssets. It holds no plain USDS and none of SparkLend's USDS supply token spUSDS (0xC02a...4359, read from the SparkLend pool's reserve data). It also holds 227.60m Spark Savings spUSDT (about 235.5m USDT), matching the API's 'Spark USDT'. So the API's 'Spark USDS' $725.2m is savings USDS, a wrapper over USDS, not a SparkLend loan..A
