On-Chain Memo Format

{"t":"RLUSD","m":"2025-11","h":"17673a2f...","s":1260898084}

Note: snapshot_id format is rlusd_YYYYMM_TIMESTAMP. Get actual IDs from /api/v3/rlusd/latest or /history.

t = Type (RLUSD)
m = Report Month
h = Content Hash (32 chars)
s = Circulating Supply

Anchors Explained

/api/v3/rlusd/anchors returns the on-chain anchor references for each attestation snapshot.

XRPL anchor is the primary reference (tx hash + ledger index)
Optional backup anchors can exist on EVM chains (tx hash + block number)
