SEI is executing a "scorched earth" technical pivot with the SIP-3 upgrade.

The team is deleting over 200,000 lines of legacy Cosmos code to transform Sei into a Pure EVM chain.

This "lean and mean" architecture is the final hurdle before the Giga Upgrade, which targets 200,000 TPS and 400ms finality.

By mid-2026, Sei will no longer support dual-stack addresses, making it the most streamlined execution environment for institutional high-frequency trading.
