Mainnet TX signed via 2PC-MPC and broadcast on Zcash:
ZIP 244 v5 sighash computed in TypeScript, verified byte-for-byte against librustzcash. BLAKE2b with 16 Zcash-specific personalizations. The full key never existed whole.
ZAP1 protocol running continuously. 39 leaves, 4 mainnet anchors, 21 event types. Health check: curl https://pay.frontiercompute.io/health returns sync_lag: 0. Six containers, Zebra 4.3.0, zero downtime since deploy. Embedded Orchard wallet builds and broadcasts anchor TXs without external wallet dependencies.
Zcash Merkle roots verifiable on 5 chains (Ethereum mainnet, Arbitrum, Base, Hyperliquid, NEAR). The ETH mainnet verifier uses the EIP-152 BLAKE2b precompile at address 0x09, running Zcash-native cryptographic verification natively inside the EVM. Contract:
