Launching High-Yield Reinsurance Bonds that use crypto restaking to lower healthcare costs, improve coverage, and return profits to the users.
Opolis, a community revolutionizing employment and benefits, is bringing health insurance on-chain—replacing bloated intermediaries with lower premiums, better coverage, and efficient administration.
Starting this month, Opolis is partnering with Renzo Protocol and EigenCloud to launch onchain
Reinsurance Bonds using Renzo’s Flow Vaults infrastructure—creating the first live real-world application of restaking in the insurance sector. This effort is supported by an EigenCloud Grant and a strategic investment from Renzo, underscoring deep alignment around building meaningful RealFi infrastructure.
This is not just a case study. It’s the deployment of RealFi, replacing traditional reinsurers with crypto-native, fixed-term vaults that underwrite actual health plans.
Why Insurance Needs a Reset
The U.S. healthcare system is a $4.5 trillion market, but much of that value never reaches care delivery. While insurers are capped at 15% profit margins (the “Medical Loss Ratio”), they still manage to net $75 billion in profits annually.
How? By inflating admin overhead and claims to justify higher premiums. It’s a system that rewards denial over delivery and prices most groups—especially freelancers, startups, and DAOs—out of quality plans.
At Opolis, we’ve spent the last few years building better employment infrastructure: payroll, benefits access, and cooperative ownership. Now we’re upgrading the financial layer that backs it, starting with reinsurance.
“This is what RealFi looks like: real healthcare insurance, real returns, and real people covered.”
— John Paller, Founder, Opolis
What Are Reinsurance Bonds?
Reinsurance is the insurance behind the insurance. It’s where health plans get protection from catastrophic losses, and it’s where incumbents stash profits in affiliated reinsurers with little oversight.
With Renzo and EigenCloud’s help, we’re changing that. Instead of opaque reinsurance contracts, we now use Renzo Flow Vaults to create onchain, fixed-term vaults that lock restaked AUSD and pay yield from premium profits. That capital underwrites Opolis health plans, giving us predictable, guaranteed reserves without going through legacy players.
“Leveraging restaking on EigenCloud, the Renzo–Opolis partnership delivers web3’s first real yield use case with real-world impact.”
— Lucas Kozinski, Co-Founder, Renzo Protocol
These vaults function like zero-coupon bonds: depositors provide capital upfront with a fixed maturity date and earn a return via underwriting profits, which—when claims come in at or below the expected amount—are returned to the bondholders as a real-world yield.
How It Works
1. Opolis’ Opus I Vault Setup
We define the deposit asset, term, payout structure, and raise cap. Opolis’ first vault, called Opus I, uses a yield-bearing stablecoin, AUSD, with a 6-month term, 40% fixed APY, and zero risk of slashing. This first deposit vault closes on July 31, and the bond matures on January 31, 2026.
2. Capital Raise
Vaulted capital is deployed via Renzo’s Flow Vaults into yield-bearing positions that support Opolis’ Opus I reinsurance pool. These positions generate stable, onchain returns tied to healthcare premium flows.
3. Restaking & Delegation
Vaulted capital is restaked and delegated to an AVS. In this case, a smart contract that backs Opolis’ Opus I reinsurance pool.
4. Maturity & Payout
At maturity, LPs claim their principal plus yield, which is derived from excess underwriting profits not employed to cover claims.
This setup creates a fully onchain, auditable mechanism for capital-efficient insurance, without the inefficiencies of third-party reinsurers. Opus I is the first in a series of bonds underwriting health insurance plans, built by Opolis.
Why This Is a Big Deal
We’re not just creating another DeFi vault. We’re using blockchain rails to deliver actual health coverage to freelancers, DAOs, innovators, and even normal groups that have been priced out or ignored by the legacy system.
Opolis’s Reinsurance Bonds solve real problems:
- Lower premiums by removing admin bloat
- Better coverage through guaranteed collateral
- Transparent finance with yield tied directly to real-world outcomes
- Aligned incentives between patients, stakers, and providers
“This is what the verifiable cloud was built for: real-world impact, programmable trust, and open systems that serve people at scale. ”
— Sreeram Kannan, Founder, EigenCloud
Our first $500K vault, launching July 22nd, on Renzo and restaked on EigenCloud will underwrite coverage for the first ~2,500 lives in our new Coalition Healthcare plans. Those plans go live in beta this fall and will be available to the public January 1, 2026.
The Bigger Picture: Coalition Healthcare
This is just the start.
For plan year 2026 (starting January 1, 2026), we’re introducing Coalition Healthcare, a zero-cost care model with no copays or deductibles, powered by direct provider relationships and real-time payments. By eliminating claims friction and cutting waste, we estimate savings of est 25–50%, which we return to Members and bondholders.
Opolis is building a cooperative-owned stack for employment and benefits. With Renzo and EigenCloud, we’ve added a decentralized reinsurance engine—one that doesn’t just protect lives, but rewards people for keeping each other healthy.
This isn’t just a new insurance model. It’s a movement. We’re bringing sanity, humanity, and ethics to health insurance, replacing bloated middlemen with a system that puts people first.
If you’ve ever felt trapped, overcharged, or unseen by the healthcare insurance industry, you’re not alone. Join us in building something better. By us, for us.
