Synthetix governance votes to retire sUSD, pay holders in SNX tokens

Synthetix is pulling the plug on its legacy synthetic stablecoin. SIP-423, introduced on June 12 by founder Kain Warwick and core contributor Benjamin Celermajer, proposes retiring sUSD across both Ethereum mainnet and Optimism, compensating holders with newly minted SNX tokens.

The conversion math works like this: holders receive 4 SNX for every $1 of sUSD they hold, which effectively pegs SNX at a reference price of $0.25 for the purposes of this exchange. The catch is those tokens come with strings attached, specifically a one-year lock-up followed by a one-year vesting schedule.

A stablecoin that stopped being stable

sUSD was supposed to trade at $1. It’s currently trading around $0.25, according to CoinGecko and DefiLlama data. Roughly 40 million sUSD remains in circulation, which means the protocol is looking at compensating holders for approximately $40 million in face value.

The proposal also revises the Debt Jubilee program associated with the 420 Pool, a mechanism previously established to manage legacy debt within the protocol. Under the new terms, staking ratio requirements for sUSD are removed entirely. Excess debt can either be repaid early or carried under a new four-year lock period with one-year vesting terms.

A governance snapshot vote was estimated for June 26, 2026. The Synthetix governance model requires 4 out of 7 Spartan Council signatures for proposals to pass.

Why Synthetix is doing this now

Synthetix has been signaling a strategic pivot for months. The protocol is shifting its focus toward perpetual futures trading on Ethereum mainnet, moving away from the synthetic asset model that once defined its identity. SIP-423 is essentially the cleanup phase of that transition, decoupling SNX staking from legacy sUSD obligations.

The proposal also outlines buyback initiatives for both SNX and sUSD, with the stated goal of restoring the peg by the end of Q2 2026.

Additional implementation details are expected through a follow-up proposal, SIP-424.

What this means for investors

If you’re holding sUSD right now, you’d receive SNX tokens valued at $1 per sUSD at face value, but those tokens are locked for a year and then vest over another year. SNX would need to hold above $0.25 just for holders to break even relative to current sUSD market value.

For existing SNX holders, the minting of new tokens to compensate sUSD holders is dilutive by definition. But removing the legacy debt overhang could theoretically make the protocol more attractive to new capital, particularly as Synthetix leans into its perpetual futures business.
