Built for Real Teams
Several Web3 teams are currently in private testing with ShieldCard, managing their internal treasury operations with confidential spend controls. Interested in early access for your team? Reach out via GitHub or Twitter.
What you get
Encrypted Policy Enforcement
Spend thresholds and approval rules evaluated on ciphertext using Fhenix CoFHE. No plaintext ever hits the chain.
Testnet Settlement Rail
Approved requests settle via MockUSDC on Arbitrum Sepolia. Hash-chained receipts form a tamper-evident audit trail.
Scoped Auditor Access
Grant per-request decryption permits to a designated auditor. Scope is enforced by the FHE ACL — not by access controls you have to remember to set.
Tamper-Evident Audit Trail
Every decision is chained to the previous receipt hash. Any tamper attempt breaks verification at /verify.
