Yearn Finance is the original DeFi yield aggregator: a protocol whose vaults take a user's deposit and route it through whatever lending and liquidity strategies are earning the most at that moment, auto-compounding the returns so an ordinary depositor gets an actively-managed yield without doing the work. It grew out of iearn, a set of contracts Andre Cronje built in 2020 to rebalance stablecoins across lending markets. Yearn matters to DAO history less for the vaults than for how its token arrived — the YFI fair launch became the template every "no premine, no VC allocation" project has cited since — and for what the DAO did afterward: it voted to inflate its own supply, then bolted a Curve-style vote-escrow lock onto governance. Yearn is a live record of a community repricing and re-architecting its own token by proposal.

The fair launch and yGov

On 17 July 2020 Cronje released YFI with what he described as "a completely valueless 0 supply token" — no allocation to himself, no team or investor slice, no premine. All 30,000 YFI were distributed to people who supplied liquidity to designated pools over roughly a week; the only way to get any was to use the protocol. (Yearn docs: YFI) That distribution — later shorthanded as the DeFi "fair launch" — put governance entirely in the hands of users from day one, and it is the property most often held up as the antidote to the insider-heavy token distributions common elsewhere.

Governance runs as yGov: Yearn Improvement Proposals (YIPs) are debated on the governance forum, ratified by Snapshot token vote, and executed by a multisig — an off-chain-signalling / on-chain-execution split that predated most tooling and is still common today. Contributor pay was an early problem Yearn solved in public, pioneering peer-allocated compensation through Coordinape (which spun out of Yearn) rather than top-down salaries.

yVaults, the treasury, and a DAO that repriced its own token

The product is the yVault: deposit an asset, and Yearn's strategies farm it — supplying to lending markets, providing liquidity, harvesting and re-depositing rewards — abstracting a full yield-farming operation behind one token. Because that machinery earns real protocol revenue, Yearn's governance has repeatedly had to decide what to do with the money, and those decisions rewrote YFI's own economics twice.

First, supply. The 30,000-cap was never sacred: YIP-57 (Feb 2021) minted 6,666 new YFI — about 22% of the supply — with one-third earmarked for contributor retention and two-thirds sent to the treasury under governance control, taking the total to 36,666. A community that had prized its fixed, fairly-launched supply voted, in the open, to dilute itself to fund the protocol's future — one of the clearest examples of a DAO exercising monetary policy over its own token by vote. Second, the treasury flywheel: YIP-56 ("Buyback and Build") disbanded the old YFI staking-rewards system and redirected protocol earnings into buying YFI back from the market for the treasury and contributor rewards — routing value to the DAO's balance sheet instead of paying it straight out to stakers.

veYFI: Yearn adopts vote-escrow

In 2022 Yearn added a vote-escrow layer modelled on Curve's veCRV. Locking YFI mints non-transferable veYFI for a term of one week to four years; a four-year lock carries 100% weight, two years 50%, and the weight decays as the unlock date nears and must be renewed. veYFI holders capture the bulk of gauge rewards — vaults emit dYFI (a token redeemable for YFI), and lockers can boost their share up to 10× based on how much veYFI they hold relative to their vault deposits; unlocked depositors earn only the base 10%. The distinctive twist is the early-exit penalty: leaving before the lock ends forfeits min(75%, time_left / 4 years) of the position — up to three-quarters — and the forfeited YFI is redistributed to the remaining lockers, so patience is paid for by the impatient. (veYFI docs)

The move placed Yearn firmly inside the vote-escrow lineage alongside Curve, Convex, Balancer and Frax — the same bargain of trading liquidity for time-weighted say, and the same open question of whether that locked weight stays with committed holders or gets aggregated and rented a layer up.

How Caper approaches this

Yearn's fair launch is rightly admired: no premine, no insider slice, governance in users' hands from block one. But the launch settled who got the token, not how the token confers power — and there the story is familiar. YFI is transferable and tradable, so influence tracks holdings; the DAO minted 22% more of it by vote; and to re-couple control to commitment Yearn ultimately reached for a Curve-style lock, inheriting the same ve-model tensions the rest of that cluster lives with. A caper pursues the coupling Yearn's lock was reaching for without a lock to tokenise: its voting weight combines the stake a member holds with the participation they have actually earned, and that participation record is soulbound — non-transferable by construction, so it cannot be bought, borrowed or aggregated the way locked veYFI can. Supply is not a governance lever either: a caper's tokens come from a bonding curve, not a mint proposal, so there is no equivalent of a YIP-57 dilution vote. And because that same earned weight is each member's pro-rata exit claim on the treasury, say stays tied to real economic exposure. This is a design contrast, not a claim of superiority; the mechanics are on the linked pages and verified against the contract.
