  buyer: Address                  // Buyer's wallet
  amount: bigint                  // Amount in token decimals (e.g. 1000 USDT = 1000000000n)
  maturityTimeDays?: bigint       // Optional: auto-release after X days (0 = no auto-release)
  arbiter?: Address               // Optional: dispute resolver (default = zero address)
  title: string                   // Deal title (shown in UI)
  ipfsHash?: string               // Optional: IPFS hash of description/images
}

Returns

• escrowId – The new escrow ID
• txHash – Transaction hash
