I just built Privyra for you and me 🦑
⋙ Introducing @PrivyraBids ➘
On-chain auctions are broken.
Submit a bid → bots see it → you get undercut by 1 wei.
Privyra fixes that with sealed-bid auctions where no one, not even the program can see your bid.
⋙ Stacked on:
@solana (coordination)
@encrypt_xyz REFHE-BGV → encrypted bids on-chain
@ikadotxyz 2PC-MPC dWallets → native cross-chain settlement (no bridges)
⋙ How it works: (video demo below explains it )
Submit ciphertext + ZK proof →
FHE_MAX runs on encrypted bids →
Only winner revealed. Losing bids stay private.
⋙ Settlement:
Each auction uses an Ika dWallet (2PC-MPC key, no single owner).
Winner is computed → Ika signs → real BTC/ETH delivered cross-chain.
⋙ Core program (3 instructions):
create_auction
submit_encrypted_bid
resolve_auction

Encrypt + Ika are pre-alpha → so Privyra runs simulation-accurate integration today. When they go live, the sim layer drops everything else stays.
Built for Encrypt × Ika Frontier Hackathon.
