Independent assurance.
Before signing.
TXShield provides transaction assurance infrastructure for institutional digital assets. It adds a control point between transaction creation and an institution’s existing custody or signing infrastructure.
Our focus
Digital-asset operations need a clear decision before a transaction becomes irreversible. TXShield assesses transaction integrity, organisational policy and execution risk, returning a decision that fits into the institution’s authorisation workflow.
The institution retains its custody, private keys and signing infrastructure. TXShield complements those systems with independent transaction assurance and decision evidence where supported.
Operated by Grundlabs
TXShield is operated by Grundlabs, a software company based in Germany. The portfolio also includes ChainEvidence for chain analytics and compliance evidence, and Paya for stablecoin payment infrastructure.
ChainEvidence and TXShield are separate products. TXShield focuses on technical transaction controls before signing; it does not replace dedicated KYT, AML or sanctions infrastructure.
Paya screens its payments through the TXShield API in production, using the same API available to customers.
