Polygon Discloses Fixed Security Flaws; Stellar Tokenized RWA Market Tops $4B

Polygon has disclosed several previously private security vulnerabilities that could have disrupted its proof-of-stake network, revealing that the issues were patched through the Austin and Kyoto hard forks before public disclosure. The flaws affected Polygon's Bor and Heimdall clients and included denial-of-service risks, validator resource exhaustion, and bugs affecting checkpoint and milestone processing. Polygon confirmed that none of the vulnerabilities were observed being exploited on mainnet, though nodes running older client versions past the hard fork activation heights have fallen out of consensus and must upgrade to rejoin the canonical network.

The value of tokenized real-world assets on Stellar has surged roughly 360% in 2026 to nearly $4 billion, up from $868.8 million at the end of last year, according to data from Aug. 29. Stellar's RWA market cap now stands at $3.996 billion, spread across US Treasuries, private and public credit, non-US government debt, and other tokenized asset classes. Institutional adoption is also accelerating, with DTCC planning to connect its tokenization service to the network and Tradable announcing plans to bring up to $1 billion in private credit assets to Stellar.

Tokenized stock activity saw explosive growth over the past 30 days, with monthly transfer volume climbing more than 415% to $29.5 billion, according to RWA.xyz data. Monthly active addresses rose over 209% to approximately 1.3 million, while the number of tokenized stock holders climbed 167% to 2.36 million. The total value of tokenized stocks distributed onchain reached $2.54 billion, up roughly 637% from $344 million a year ago, as platforms like Coinbase launched tokenized US stocks on Base and Bitwise introduced automated portfolios built from these assets. Separately, a Trump-promoted token briefly surged before collapsing, underscoring the volatility of politically-linked digital assets.
