Add Swap Conditional Reveal with Multi-Party Signatures

[fejilaup-cloud]

Description

For complex IP sales involving multiple parties (e.g., co-inventors), the decryption key should only be revealed if all parties sign off. Currently, only the seller can reveal.

Tasks

• Add required_signers: Vec to SwapRecord
• Implement initiate_swap_with_signers(env, ip_id, price, signers) -> u64
• Implement sign_swap_reveal(env, swap_id) — any required signer
• Only allow key reveal after all signers have signed
• Add tests for multi-party reveal flow

Priority: Medium | Estimated Time: 3 hours

Hi, I’m a Web3 developer experienced in multi-party authorization and secure escrow flows. I understand the current limitation where a single seller controls key release, which is unsafe for co-inventor IP sales. I will extend SwapRecord with required_signers, implement initiate_swap_with_signers, and add a structured signing flow via sign_swap_reveal. I will enforce strict full-signature validation before key reveal, prevent partial authorization bypass, and ensure state consistency. I will also add comprehensive tests for multi-signer approval, incomplete signing, and successful key release scenarios.
