OpenEden EDEN
on-chain T-bill vault
🎭 a buttoned-up banker mon: takes the dullest paperwork in finance, short US government IOUs, and mints it into something you can hold on-chain
💬 “Everyone else is chasing the next loud thing. I keep the boring stuff: short US government IOUs, held by real custodians, paying their small steady yield. I wrap that into a token, and the yield shows up on-chain. No drama. That is the job.”
- 2022: OpenEden is founded by ex-Gemini people to bring safe government yield on-chain.
- 2023: its TBILL token launches and later becomes the first tokenized Treasury fund with a Moody's investment-grade 'A' rating.
- 30 Sep 2025: the EDEN token finally launches to the public.
- Fixed footnote: supply is capped at 1 billion EDEN, so no new coins are minted beyond that.
📖 The Story
2022. A small team led by Jeremy Ng, who had run Gemini's Asia-Pacific business, started OpenEden with a plain idea. The safest, most boring thing in finance is a US Treasury Bill, a short-term loan to the US government. Off-chain, big institutions earn that quiet yield all day. On-chain, crypto holders mostly couldn't touch it without leaving the blockchain. OpenEden set out to close that gap.
2023. The first product, TBILL, went live. Buy the token and you hold a slice of a fund full of short-dated Treasuries and overnight repos. The token's value tracks the fund, and the fund's actual bonds sit with a regulated custodian, BNY (the BNY Mellon family), not in some anonymous wallet. That last part mattered: it let TBILL become the first tokenized US Treasury fund to earn an investment-grade 'A' rating from Moody's, later joined by a dual rating from S&P Global.
By September 2025 the TBILL fund had grown from a curiosity into roughly $260M of assets under management. Then, on 30 September 2025, the EDEN token itself launched, the key that runs the wider ecosystem.
The vault-keeper never made headlines for hype. He made them for being audited, rated, and dull in exactly the way money likes.
📊 Stats
🧩 How it works
OpenEden has no chain of its own. It is a DeFi layer that lives on Ethereum: EDEN is an ERC-20 token, with copies on chains like Arbitrum, Base, Solana, BNB Chain, and the XRP Ledger. The clever part is what backs the products. Real Treasury Bills sit with a regulated custodian off-chain, and a token on-chain tracks their value. Its stablecoin, USDO, works the same way, a steady coin that earns its yield from those bonds.
🌗 Light & Shadow
- Backed by something genuinely safe: short-dated US Treasuries, the asset most of finance treats as the baseline for ‘risk-free’
- Real audits and credit ratings (first tokenized Treasury fund with a Moody's 'A', later a dual rating from S&P Global), plus a named custodian in BNY
- Supply is fixed at 1 billion EDEN, so the token can't be quietly inflated away the way uncapped coins can
- The EDEN token is young, it only launched in September 2025, so it has little price history to judge
- Lots of EDEN is still locked. Tokens keep unlocking on a schedule into roughly 2028, which can press on the price as new supply arrives
- The yield is only as ‘safe’ as the off-chain pieces, the custodian, the issuer, and the rules of the countries they sit in (this is trust in institutions, not trustless code)
🧬 Evolution lineage
EDEN is not a fork of anything, and it has no chain of its own, it is a standalone ERC-20 token living on Ethereum. Its only ‘siblings’ are by theme: other projects that put US Treasuries on-chain. They share a category, not a codebase or a founder.
Category peers (by theme only): Ondo (ONDO), Franklin's BENJI, and BlackRock's BUIDL.

❓ FAQ
- What is OpenEden?
- A platform that tokenizes US Treasury Bills, short-term government IOUs, so you can hold their yield as a token on the blockchain. EDEN is its native token, used for holder discounts, governance, and staking.
- Does OpenEden have its own blockchain?
- No. EDEN is an ERC-20 token issued on Ethereum, with copies deployed on chains like Arbitrum, Base, Solana, BNB Chain, and the XRP Ledger. There is no OpenEden Layer 1 of its own.
- Is EDEN minted endlessly like some coins?
- No. The supply is fixed at a maximum of 1,000,000,000 EDEN, and that cap never grows. Tokens unlock on a vesting schedule that runs into roughly 2028, but no new EDEN is created beyond the 1 billion.
- How is OpenEden different from a normal stablecoin?
- A normal stablecoin just holds a steady price. OpenEden's TBILL token is backed by real US Treasuries and pays out their yield, and it was the first tokenized Treasury fund to earn an investment-grade rating from Moody's.
