- Synthetix governance has approved SIP-423, a proposal to fully decommission and deprecate its native sUSD stablecoin across Ethereum and Optimism networks.
- Holders will receive four locked SNX tokens for each sUSD based on its $1 face value, compensating users despite the asset’s current market value of $0.25.
- The transition restructures protocol debt mechanisms by winding down the 420 Jubilee Debt Pool and completely removing the sUSD staking ratio requirement.
Synthetix governance has voted to officially retire its native stablecoin, sUSD, signaling a definitive end to the protocol’s multi-year reliance on its home-grown synthetic dollar. Authored by Synthetix founder Kain Warwick and core contributor Benjamin Celermajer, the approved proposal, SIP-423, outlines a comprehensive plan to freeze and deprecate the token’s smart contracts across both the Ethereum mainnet and the Optimism Layer-2 network.
The decision follows a severe and prolonged depegging crisis for sUSD. The synthetic asset, intended to maintain a rigid $1 parity, has collapsed over the past several months, shed 61% of its value within the last 30 days, and currently trades at roughly $0.25. While the protocol previously introduced various incentive mechanisms and adjusted collateralization ratios to restore stability, SIP-423 represents the first time the community has opted for a complete wind-down rather than a system repair.
Under the approved redemption terms, the protocol will execute a contract freeze and take a final ledger snapshot of all balances. Eligible sUSD holders will be compensated at the asset’s nominal $1 face value at a conversion rate of four SNX tokens per sUSD. The newly distributed SNX tokens will be subject to a strict one-year lockup period from the freeze date, followed by an additional twelve months of linear vesting. To soften the blow for capital locked in the ecosystem, the proposal includes a conditional cash pathway: if Synthetix generates more than $10 million in protocol revenue during the next two years, 25% of those funds can be distributed in USDT to former holders who prefer fiat exposure.
Beyond asset redemption, SIP-423 drastically alters Synthetix’s underlying liquidity and credit structure. The initiative dismantles the 420 Jubilee Debt Pool established under prior governance, completely dissolves the legacy sUSD staking ratio requirement, and untethers stakers from asset obligations. Staking participants are given a choice between committing to a four-year lockup with a one-year linear vest or initiating an immediate exit by settling their remaining pool debts in full. The technical specifications to implement these smart contract changes will follow in an upcoming companion architecture proposal, SIP-424.
