Security Matters is trading 8.38% up at $19.01 after announcing a four-layer Digital Material Passport platform for plastics and a client testing experience.
- The platform connects physical plastics with digital identities, lifecycle data, and potential circularity-credit markets.
- This compares with the September 8 regular-session close of $17.54, following a 9.96% decline.
- Bitcoin and Ethereum were slightly lower and broader markets remained risk-off, so crypto and macro conditions do not explain the after-hours gain.
