The invention discloses a method for realizing a cross-chain encrypted session based on a smart contract, which can realize a point-to-point session negotiation process with an external block chain account on the premise of keeping decentralization of a block chain application between different block chain accounts, realizes a cross-chain method for establishing information and communication, and improves the security of the information and communication. Safety and privacy protection of point-to-point communication are realized by using a digital encryption technology; once the session does not need to be maintained, only the private key corresponding to the public key published by the party needs to be discarded, so that the message cannot be seen by any other person after being read, and the effect of burning after reading is achieved. 本发明公开了一种基于智能合约实现跨链加密会话方法，通过本发明方法实现不同区块链账号间在保持区块链应用的去中心化前提下，可实现与外部区块链账号点对点的会话协商过程，实现了信息及通信建立的跨链方法，并利用数字加密技术实现了点对点通信的安全及隐私保护；一旦不需要维持会话仅需要丢弃已方发布的公钥所对应的私钥，实现了阅读对方消息后，即可不再被其他任何人看
