Solana Pre-Alpha — 2PC-MPC signing for cross-chain settlement
First, create a dWallet via the Ika program (CLI or Ika dashboard). Then register it here to transfer authority to DarkBook's CPI authority PDA. DarkBook can then approve withdrawal messages signed by the Ika 2PC-MPC network.
Ika dWallets run on Solana devnet (pre-alpha). Create a dWallet via the Ika CLI, then register it here. Once registered, DarkBook's CPI authority controls the dWallet.
On position close, DarkBook can optionally call approve_dwallet_withdrawal to authorize a cross-chain payout. The Ika network detects the MessageApproval PDA and produces a 2PC-MPC signature for settlement on Bitcoin, Ethereum, or any supported chain.
Pre-alpha: Signing uses a mock signer. Real MPC security will be available at mainnet. dWallet Labs (Ika + Encrypt) — same team.
