Synthetix (SNX)

Synthetix is one of DeFi’s oldest and longest-running DAOs, and its most distinctive contribution to governance design is organizational rather than financial: instead of asking every token holder to vote on every change, it asks them to elect a small council. That council – the Spartan Council – holds the keys and executes upgrades and treasury spends through a multisig. Synthetix is therefore the reference example of representative DAO governance, sitting between direct token voting (Aave, Compound) and validator-weighted chain governance (dYdX).

The protocol began in 2018 as Havven before rebranding to Synthetix. For most of its life the core mechanic was pooled-collateral synthetic assets: SNX holders staked their tokens as collateral and minted the sUSD stablecoin, and the staked SNX backed a shared pool of on-chain synthetic assets. In 2025–2026 the DAO voted to retire that model, launching a perpetual-futures exchange on Ethereum mainnet in December 2025 and moving toward exchange-driven revenue.

The Spartan Council: elected, not direct

Synthetix is governed by the Spartan Council, a body of 7 seats. Each election cycle, 4 of the 7 seats are elected by SNX stakers; the remaining seats comprise 3 advisory seats (continuity and external perspective) and 1 treasury seat that is a required signer of all treasury transactions. Any governance proposal or treasury movement needs 4 of 7 signatures to execute, per the January 2026 elections announcement.

Historically the model ran multiple councils with separated remits – a Treasury Council managing the treasury and funding the other bodies, and an Ambassador Council advocating for Synthetix across the wider Ethereum/DeFi ecosystem (see the community-maintained guide to Synthetix governance). This deliberate split of powers into elected, separately-accountable councils is what makes Synthetix distinct from a single token-house.

Elected members receive a monthly stipend from the treasury (2,000 SNX per member per the January 2026 post) – governance work is a paid, term-limited role rather than volunteer labor.

Elections and the 420 pool

Councils are re-elected on a fixed 6-month cadence, every January and July. The January 2026 election ran a 5-day voting window (26–30 January) on a Snapshot vote open to SNX stakers. Crucially, voting eligibility is tied to staking: only SNX staked in the 420 pool before voting opens can be voted with. Staking, liquidity provision, and the right to elect the council were bound together in the same act until mid-2026.

SIP-423, which the council approved on Snapshot in June 2026, closed the 420 pool and returned SNX without outstanding debt to holders' wallets; the staking contract meant to replace it has not been built. SIP-424 therefore lets any SNX holder vote in council elections, one SNX one vote, counting SNX on Ethereum and Optimism, SNX the Treasury still holds for former 420 stakers with debt, and unclaimed SIP-423 sUSD entitlements at 4 SNX per sUSD. The council voted 4 to 0 for it in a Snapshot vote that closed on 27 August 2026, though the SIP repository still lists it as Vote_Pending. Votes on SIPs, parameter changes and treasury proposals stay with the sitting councillors.

Fixed-term elections are the accountability mechanism that a representative model needs. Because the whole council turns over on a predictable schedule, stakers who dislike the direction do not have to wait for a specific proposal – they replace the decision-makers at the next epoch.

The SIP process

Protocol changes move through Synthetix Improvement Proposals (SIPs), with treasury spends handled as Synthetix Treasury Proposals (STPs). A change starts as a written SIP in the public SIP repository, is reviewed and refined in the open, and is then put to the Spartan Council; a 4/7 council vote authorizes execution. The written-proposal-then-council-vote pipeline gives the elected body a concrete, auditable mandate for each action rather than a blanket authority.

Two recent SIPs show how far a council mandate can reach:

• SIP-420 (“the 420 Pool”), implemented January 2025, replaced individual SNX staking with a protocol-owned debt pool – a form of delegated staking. Stakers move their debt positions (not their collateral) into a single pooled contract over a 12-month transition; the pool runs at a 200% issuance ratio versus a punitive 1000% for solo stakers, and early exits carry a penalty that decays linearly from 100% to 50% over the transition.
• SIP-423 voted to retire sUSD and pay holders in vested SNX, alongside SNX and sUSD buybacks aimed at restoring the peg – a wholesale change to the protocol’s economic model, ratified through the same council pipeline (Crypto Briefing).

Why the elected-council model matters for DAOs

Direct token voting has two chronic failure modes: voter apathy (most holders never vote, so a small active minority decides everything) and whale dominance (one large bag can carry a proposal). Synthetix’s answer is to separate the electorate from the executive: holders vote rarely – only to choose a council – and a small, named, term-limited body does the day-to-day governing under a multisig. This buys execution speed and clear accountability, at the cost of concentrating power between elections and introducing council-capture and low-turnout risks of its own.

It is a genuinely different point in the design space from the vote-escrow and futarchy approaches, and worth studying precisely because it has run real elections, on a fixed cadence, for years.

How Caper approaches this

Caper does not use an elected council. Governance weight is direct and continuous: a member’s weight on any decision comes from both the tokens they hold and the votes they have earned by casting ballots, so there is no representative layer to elect or capture, and a large bag alone cannot capture control without earned votes. Proposals are typed at execution (a spend, an investment, or an executive action) rather than filtered through a standing council.

Where Synthetix uses periodic elections as its accountability mechanism, Caper uses the exit right: if you dislike the direction, you exit any time for your fair share of the treasury instead of waiting for the next election to vote a council out. See what is a caper, proposals, and raising funds.
