Spartan Council and SIP updates
When you’ve been across the Synthetix ecosystem for some time, you’ve in all probability heard that Mainnet is the longer term. Properly, it’s now not only a speaking level — the transition is occurring and it’s taking place now.
Synthetix is formally sunsetting its L2 deployments, beginning with Arbitrum and Base. Optimism will stay stay for now, however its time is coming. Transferring ahead, Ethereum Mainnet would be the sole focus of improvement, buying and selling, and liquidity. It’s the top of 1 period and the start of one other that can probably be an important section within the protocol’s historical past.
Let’s first discuss what’s already been decommissioned. The Arbitrum deployment is now absolutely deprecated. Buying and selling was disabled months in the past, and all remaining vaults have been liquidated. When you nonetheless have funds on Arbitrum, right here’s what you could know:

easy — simply hop into Discord and open a help ticket to start. The clock is ticking, and also you’ve obtained six months to assert what’s yours, so don’t wait till the final minute! For additional particulars, you’ll be able to seek advice from SIP-416.
Subsequent, let’s talk about what’s arising for these nonetheless on Base. The wind-down on Base is occurring in two steps, with key dates that every one merchants and LPs want to pay attention to:

On the identical day, Leverage Tokens will go redeem-only, so that you gained’t be capable to mint new tokens from this level ahead.
July 7: Base will likely be absolutely deprecated. This consists of the whole shutdown of all Perps and Leverage Tokens, and LP vaults will likely be liquidated. When you haven’t manually withdrawn your funds by then, any remaining collateral will likely be returned by the treasury.
To keep away from delays or slippage, be sure to shut your positions and withdraw your margin earlier than July 7. When you want extra data or assist with the method, the group is all the time obtainable on Discord.
At this level, you is likely to be questioning what’s taking place on Optimism — and what, if something, you could do. Proper now, there are not any modifications to Synthetix on Optimism, as the whole lot will stay stay and absolutely supported in the meanwhile. However its time will finally come!
Whereas there isn’t an official timeline for when Optimism will likely be deprecated, now is an effective time to start out making ready for the eventual migration to Mainnet in case you’re holding any idle sUSD on Optimism. You’ll be capable to bridge your sUSD to Ethereum quickly, the place will probably be essential for the upcoming perps system.

This isn’t simply one other deployment on Ethereum, it’s a full pivot.
Beginning on the finish of June, Synthetix will likely be launching early deposit vaults for sUSD and sUSDe. Early members will likely be rewarded with Synthetix factors, and the protocol will likely be internet hosting invite-only buying and selling competitions the place you will get early entry to the brand new perps system. That is the second the place Synthetix goes all-in on the high-performance, absolutely composable perps DEX that Ethereum has been ready for.
The shift away from rollups is not only about simplifying the system — it’s about taking management. Rollups gave the protocol some nice classes, however in the end, Ethereum L1’s safety and scalability are the place the longer term lies.
In brief, right here’s what you could know transferring ahead:
When you’re nonetheless utilizing Arbitrum, get your collateral and shut any positions.
