Sei Community is nearing its long-awaited Giga improve, with builders saying ultimate technical work has begun. Whereas many customers are centered on its launch date, the crew says crucial advances are occurring behind the scenes with SIP-3, a significant improve that may change how networks work.
SIP-3: Paving the best way for Say Giga
Co-founder Jayendra Jog mentioned within the newest replace that SIP-3 goals to simplify Sei's core mechanics. As a substitute of supporting each EVM and Cosmos transactions, the community will transfer to an EVM-only setup.
Which means that sei removes lots of previous and complicated code linked to Cosmos and CosmWasm. By offloading this additional burden, you possibly can assist your community run extra effectively and scale efficiency even additional.
Notably, the SEI neighborhood authorized this improve final Could, and it’s at present being phased in.
What EVM-Solely actually means to Sei
As soon as SIP-3 is totally deployed, solely EVM addresses will be capable to ship transactions on Sei, and Cosmos-based transactions might be phased out.
This will likely seem to be a small change, nevertheless it's an enormous one. By focusing solely on EVM, SEI can higher optimize efficiency, instruments, and infrastructure. The crew says this streamlined method made gig upgrades potential.
Sei goals to develop into a totally EVM-only chain by mid-2026, with most of SIP-3 accomplished by the tip of Q1 2026.
TL;DR: Seigiga will seem https://t.co/aJjLJf3P9H

Community launch and timeline
SIP-3 might be rolled out by means of a number of protocol updates.
- v6.3 (Testnet – January-March): Provides full staking through EVM and permits indexers and custodians to trace staking utilizing the EVM API.
- v6.4 (Testnet – January-March): Sei can now block inbound IBC transfers and forestall Cosmos-based property from being bridged in.
In a future replace, outbound IBC transfers can even be shut down and sei's native oracles might be changed with established suppliers reminiscent of Chainlink, API3, and Pyth. These adjustments might be reside on mainnet solely after governance approval, which is predicted in the direction of the tip of Q1 2026.
Essential actions for Sei customers
The SIP-3 improve contains necessary warnings for some customers.
- USDC.n holder needs to be switched to native USDCOtherwise you danger shedding entry if IBC forwarding is turned off.
- Different IBC property reminiscent of ATOM will have to be moved out of Sei earlier than the mainnet adjustments.
- DeFi customers counting on IBC tokens are suggested to shut their positions early.
Sei Labs suggests utilizing third-party instruments like Skip:Go to handle migrations, however cautions customers to do their very own analysis.
Seigiga and 200,000TPS purpose
With SIP-3 appearing as a “lightening” section, SEI Giga is the subsequent step in pushing throughput into the 200,000 transactions/second vary.
Neighborhood leaders describe SIP-3 as a efficiency reset reasonably than a daily improve. Sei believes that by eliminating complexity and specializing in a single design, it might probably scale extra effectively than different high-TPS chains that also depend on layered architectures.
Designing for a post-quantum future
Some within the Sei neighborhood are already centered not solely on velocity, but in addition on long-term safety because the community grows. One subject that’s gaining traction is post-quantum cryptography. This makes use of a lot bigger signatures and better verification prices, which might tax high-throughput blockchains.
The Sei contributors say the community's design lends itself nicely to approaches reminiscent of proof batching, recursive verification, and incentive-based safety. Sei treats quantum resistance not as a easy key change, however as a broader techniques problem that should work in parallel with excessive efficiency.
Though no blockchain is totally quantum-proof but, proponents consider Say's performance-first method may very well be a bonus in the long term.
In whole
SIP-3 is an enormous change for Sei Community. By shifting to an EVM-only mannequin, simplifying protocols, and getting ready for Gig, Say is betting on efficiency, scalability, and long-term flexibility.
With Giga's main bulletins teased as “coming quickly,” the main target is on how nicely these upgrades will carry out and whether or not Sei will be capable to obtain its purpose of redefining high-performance layer 1 blockchains.
