The "audited end-to-end encryption" link should actually go to:
https://delta.chat/en/help#security-audits
It's also fixed on https://delta.chat now.
Status: there are 5 published independent audits and one published security analysis from the ETH Applied Crypto Group. There is another soon to be published audit, and more audits scheduled this year.
