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](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:

Tested Zebra PR #10170 (precompute coinbase) against our s-nomp pool on mainnet. GBT returns a valid template, no regressions in the response format pool software expects. Results posted on the PR.

npm: 2,300 downloads/week across 7 packages. zcash-mcp merged into [GitHub - punkpeye/awesome-mcp-servers: A collection of MCP servers. · GitHub](https://github.com/punkpeye/awesome-mcp-servers) (84K stars). Cross-platform conformance suite with 39 test vectors for memo parsing.

All code MIT licensed. 24 public repos: [Frontier Compute · GitHub](https://github.com/Frontier-Compute) . No cloud dependencies. Anyone can clone and run.
