Description

In order to interact with the Blockchain you would need to set the contract addresses in your .env file in the following manner:

TOKEN_CONTRACT=0x...

CASHIER_CONTRACT=0x...

Here are all the functions the Service currently provides and some useful information:

• async getSigner() returns JsonRpcSigner
• async getUserAddress() -> returns current logged user eth address
• async signMessage(signer, nonce) -> returns signature which later will be used by the API service to authenticate the user
• async requestCreateOrder(contractArgs: Array, value) -> Broadcast tx to the blockchain. Returns parsed event from the BC transaction
• async commitToBuy(contractArgs: Array, value) -> Broadcast tx to the blockchain. Returns parsed event from the BC transaction
• async refund(voucherID) -> Broadcast tx to the blockchain. Returns parsed event from the BC transaction
• async complain(voucherID) -> Broadcast tx to the blockchain. Returns parsed event from the BC transaction
• async cancelOrFault(voucherID) -> Broadcast tx to the blockchain. Returns parsed event from the BC transaction
