- Sei Network Proposes Post-Quantum Security Upgrade Amid SEI Price Volatility — this brief
Sei Network has proposed a new security mechanism as part of its SIP-5 proposal, aiming to protect the network against potential threats from quantum computing. The proposal outlines a system for users to register ML-DSA signatures, which are designed to be resistant to quantum attacks.
Existing EVM accounts on the network will be able to migrate to the new system while preserving their current addresses and balances, ensuring a smooth transition for users. This development comes as the broader crypto market remains relatively flat, with a total market cap of $2.79 trillion.
The SEI token is currently testing the $0.060–$0.062 support zone, according to TronWeekly. The token is trading at $0.061733, down 3.92% in the last 24 hours and 11.37% over the past week. Despite the short-term volatility, the token's market cap stands at $415.67 million.
The broader market sentiment, as measured by the Fear & Greed Index, remains in 'Greed' territory at 55, indicating a cautious optimism among investors. The 
Bitcoin price has decreased by 0.64% in the last 24 hours, reflecting the overall market's flat performance.
The introduction of post-quantum security measures could be a significant step for Sei Network, potentially attracting users concerned about the long-term security of their digital assets. Investors will be watching to see if the SEI token can break out of its current support zone and move toward the mid-$0.07 range.
Since this brief published about 1 hour ago, Sei (SEI) has moved from ₹5.87$0.0617 to ₹5.91$0.0621 — +0.58%.

At today's peer-to-peer rate, 1 SEI ≈ ₹6.48 (about $0.0621), down 4.2% over 24 hours. The rupee itself trades about 9.7% above the official rate on the P2P market, so a Indian buyer's effective cost differs from the headline dollar price.
