How this service works
Weekly scoreboard grading tokenized RWA promises against verified on chain reality. Every number carries an evidence grade and a retrieval timestamp; the archive is append only.
Output
A JSON object containing per-fund rows for BUIDL, USDY, USYC, and OUSG, each with on-chain supply (grade A, read directly from Ethereum contracts), DefiLlama all-chain circulation (grade B), Ethereum chain share percentage, and an aggregate total value across all tracked funds.
Example use cases
Verifying BUIDL supply against reported figures
“Check Realedger for BUIDL's actual on-chain supply from its Ethereum contract and compare it to the total all-chain circulation — I want to see if the on-chain reality matches what's being reported.”
Monitoring Ethereum concentration for treasury funds
“What percentage of USDY and OUSG's total supply is actually sitting on Ethereum right now? Pull the chain share data from Realedger so I can see how concentrated each fund is.”
RWA dashboard for tokenized treasury TVL
“Give me the latest on-chain supply and USD notional value for all four tokenized treasury funds — BUIDL, USDY, USYC, and OUSG — with both the grade A Ethereum contract numbers and grade B cross-chain totals.”
Technical details
Endpoint
GEThttps://api.realedger.xyz/v1/treasuries-onchainWhen to prefer
Choose this endpoint when you need cryptographically verifiable, contract-sourced supply data for tokenized treasury funds (BUIDL, USDY, USYC, OUSG) rather than relying solely on self-reported figures. It is the right choice when you need both Ethereum-native (grade A) and cross-chain (grade B) views side by side, or when auditing the gap between promise and proof for RWA tokenization claims.
Side effects
- Ethereum RPC or contract read failure returns incomplete or missing grade A data
- DefiLlama API unavailability causes missing grade B circulation figures
- Stale data if on-chain indexing is delayed
- 402 Payment Required if USDC payment is not attached or insufficient
- Unknown or unsupported fund ticker returns empty or null row
