Synthetix completes SIP-423, deprecates sUSD with 4:1 SNX conversion

Synthetix delivered the primary outcomes of SIP-423, which deprecates its native sUSD stablecoin — the founding mission of the original 2017 Havven project. The change, approved on June 19, mints new SNX at a 4:1 ratio with sUSD (236,464,356 SNX minted, bringing supply from 344,939,867.56 to 581,404,223.56 SNX), with a 1-year lock followed by 1-year vesting.
- sUSD holders can check their SNX entitlement on a dedicated dashboard; balances may not appear if held in an LP position or an L2 Safe wallet.
- Synthetix frames the move as a "hard reset" that removes endogenous dependencies, positioning the protocol to scale as a perp venue on Ethereum Mainnet.
