It's nice seeing a lot of @SeiNetwork updates on the timeline with many people out there now bullish on SEI.
Sei's GIGA upgrade promises blazing-fast throughput and parallel execution which is becoming evident as the days go by —but it wouldn’t be possible without SIP-3, the quiet foundation beneath it all.
SIP-3 is Sei’s shift to an EVM-only chain, sunsetting CosmWasm and Cosmos-native transactions to unify its architecture.
__________________
Why was this proposed?
Because dual runtimes = complexity.
EVM-only = speed, simplicity, and scale.
Here's why it matters:
• GIGA introduces Autobahn consensus, async + parallel execution, and SeiDB.
• But those optimizations need a clean, streamlined execution layer.
• SIP-3 clears that path by making everything—from staking to governance—EVM-native via precompiles.
• That means builders get full EVM compatibility + supercharged speed, without Cosmos friction.
SIP-3 is already live (Phase 1), with full deprecation of legacy systems on the horizon.

Here's a breakdown of the Phases:
●Phase 1 – EVM Pointer Creation
- Establishes links (“pointers”) for existing CosmWasm and Cosmos assets to be accessible via EVM accounts.
- Ensures assets aren’t locked out during the transition.
●Phase 2 – Deprecation of New CosmWasm & IBC Inbound
- Freezes deployment of new CosmWasm contracts.
- Disables inbound IBC (Inter-Blockchain Communication) for Cosmos-style tokens.
●Phase 3 – Full Removal of Legacy Support
- Disables execution of existing CosmWasm contracts.
- Removes support for native Cosmos transactions and non‑EVM addresses.

Where things stand now:
• Formal approval happened earlier this month.
• Implementation (phased removal of CosmWasm and native Cosmos transactions) is underway.
• Further detailed timelines and technical checkpoints are expected to be published soon, guiding validators, builders, and users on the next steps.
SIP-3 is the architectural refactor that makes GIGA possible.
GIGA brings the speed—and SIP-3 brings the foundation.
Together, they’re turning Sei into the fastest, most usable EVM chain in the game and it's becoming evident in price.

BREAKING: Sei's mindshare is up 216% in the last 24 hours outpacing giants like PENGU, BNB, AVAX, SOL and HYPE.
