Stellar launches Bell upgrade in November to add post-quantum security for smart contracts.

Stellar is set to introduce the Bell upgrade in November, marking its first step toward post-quantum security by enabling native post-quantum signatures for smart contracts. This upgrade, hitting Testnet on November 3 and potentially Mainnet by November 23, aims to prepare smart accounts for large-scale business use and initiate broader quantum-safe measures. Stellar targets full quantum security by 2027, aligning with industry efforts to counter threats from powerful quantum computers. The upgrade has positively influenced Stellar's XLM token, which saw a short-term price increase following the announcement.

As of Oct 21, 2026 19:02 WIB, Stellar's XLM token trades at Rp3.313 on Pluang, showing a 4.02% gain over the past day. The token's market cap stands at Rp117,12 trillion with a 24-hour trading volume of Rp2,56 trillion. Despite the recent price rise linked to the Bell upgrade news, most Pluang users are selling, with 86% of order activity on the platform being sell orders.
