PCHAIN

The PCHAIN Network supports cross-chain calls. With the toolkit provided by the PCHAIN Network, the smart contract on the PCHAIN Network can be invoked using non-native Tokens of other chains. The toolkit currently supports BCH and Tokens following the ERC20 protocol.The principle is as follows. When the toolkit provided by the PCHAIN Network, which is used on other blockchains, invokes the smart contract of the PCHAIN Network with a certain number of Tokens in this blockchain, the exchange rate between the Token and PAI (Token of the PCHAIN Network) will be acquired by the toolkit firstly through the smart data in Knowledge Graph. When the convertible PAI is enough to run the called smart contract, the toolkit will transfer the corresponding number of Tokens to the PCHAIN Network and consume the corresponding quantity of PAI of the PCHAIN Network to invoke the smart contract.
