feat(rwa-yield-accuracy): Sprint 3 — restrict V1 to USDY, mark draft - #1326
Merged
Conversation
…draft
Cross-check pass via WebFetch revealed two blockers for shipping the
full 5-token cohort live:
1. BUIDL and USTB treasury wallet addresses are not visible on the
public Etherscan token page. Shipping the dividend probes without
verified treasury addresses would count zero USDC transfers and
report a delivered yield of 0 bps against a promised 350 bps -
a -350 bps deviation that would look catastrophic and be entirely
an artefact.
2. BENJI and OUSG NAV JSON endpoints as guessed (franklintempleton
.com/api/... and api.ondo.finance/v1/...) return HTTP failures.
Franklin loads NAV via JS render; Ondo's endpoint does not exist
at the guessed path. Shipping the NAV probes without verified
endpoints would report nav_source_err on every tick.
Rather than pollute the bench with placeholder data, V1 restricts
the active cohort to USDY, whose rebase mechanism is fully verifiable
on-chain (single ERC-20 contract, totalSupply growth). The other 4
probes stay in the repo (buidl.go, ustb.go, benji.go, ousg.go), fully
implemented and dormant. They activate one by one as each treasury
address or NAV endpoint gets verified against the issuer's own docs.
Also updates promised-yields.yml with values pulled directly from
issuer dashboards (USDY 3.55%, USTB 3.52%, others best-estimate).
Prior values (5.30-5.40%) reflected 2024 rates before Fed cuts.
The bench spec is marked status: draft so it's tracked in the repo
but doesn't surface on the public site until USDY has run long
enough to publish a defensible 30-day delivered yield.
