The short answer

OUSD and OETH deliver yield by increasing your token balance directly, which is the least demanding user experience in DeFi, with published strategy allocations. Origin was exploited for around $7m in 2020 through a flash-loan attack and repaid affected users in full — the response that let the protocol survive.

What we liked

  • Rebasing tokens compound automatically with no claiming
  • Strategy allocations are published and updated
  • Fully repaid users after its 2020 OUSD exploit

Where it falls short

  • A $7m flash-loan exploit in 2020 remains on the record
  • Rebasing tokens behave awkwardly in other DeFi protocols

Most yield products require claiming, compounding or wrapping. Origin's rebasing tokens simply increase your balance as yield accrues, with no action required and no separate reward token to manage.

How the yield is generated

OUSD allocates across lending markets and stablecoin strategies; OETH across liquid staking and ETH yield strategies. Allocations are published and updated, so a depositor can see which protocols their capital is exposed to. Fees run roughly 10–20% of yield generated.

The 2020 exploit

A flash-loan attack manipulated a price used by OUSD's strategy, extracting around $7m. Origin published a full post-mortem, pursued recovery, and committed to compensating affected users, which it completed over the following period. Protocols that repay after an exploit are the exception rather than the rule, and it is the main reason the protocol retained any users at all.

The rebasing trade-off

A balance that changes automatically causes friction in DeFi protocols that assume static balances, and in some tax jurisdictions the accounting is more complex than for a value-accruing token. Wrapped non-rebasing versions exist for integration purposes.

Who should use it

Users who want passive stablecoin or ETH yield with no maintenance, at moderate size, and who have read where the strategies allocate. The 2020 incident is old but it is the relevant data point about how this team responds under pressure — favourably, as it turned out.

FAQ

What does rebasing mean?
Your token balance increases automatically as yield accrues, rather than the token's value rising or requiring a claim transaction.
What happened in Origin's 2020 exploit?
A flash-loan attack manipulated a price feed used by OUSD's strategy, extracting around $7m. Origin published a post-mortem and compensated affected users in full.
Where does OUSD's yield come from?
Allocations across lending markets and stablecoin strategies, published by the protocol and updated as positions change.
Do rebasing tokens work in DeFi?
Imperfectly. Many protocols assume static balances, so wrapped non-rebasing versions exist for integration.
