Cross-chain ZEC (transparent) via NEAR Chain Signatures.
NEAR's MPC network (v1.signer) can sign Zcash transparent transactions via secp256k1 (Cait-Sith protocol). One NEAR account derives keys for Zcash, Bitcoin, and Ethereum. Every cross-chain op attested on Zcash via ZAP1.
| Domain | Scheme | Zcash use | Status |
|---|---|---|---|
| 0 | secp256k1 (Cait-Sith) | ZEC transparent, BTC, EVM | Confirmed on mainnet |
Zcash shielded (Orchard) requires RedPallas signatures on the Pallas curve. NEAR's MPC supports secp256k1 and Ed25519, but NOT Pallas. Ed25519 is not the same as RedPallas. There is no path from NEAR Chain Signatures to Orchard signing today. Same for Sapling (RedJubjub on Jubjub).
npm install @frontiercompute/zap1-nearnpm run build && node dist/test.jsQueries v1.signer on NEAR mainnet (view calls only, no keys needed).
