Delphi Oracle EVM Bridge

This repository contains the Telos Delphi Oracle EVM <> Antelope Bridge.

The bridge requires the deployment of 3 components to work: the EVM & Antelope components which are part of this repository and Listener component that is part of our Telos Oracle Scripts repository. Follow the instructions below to deploy it.

EVM

DelphiOracleBridge.sol

The bridge's EVM contract. Receives requests and sends responses back to a callback function. Currently deployed at

TESTNET : TBD

MAINNET : TBD

DelphiOracleConsumer.sol

Example implementation of a consumer with a DelphiOracleBridge request call and a callback function

GasOracleBridge.sol

Query current gas price from a smart contract. This contract is only included for test purposes and will not be deployed.

To learn how to deploy those contracts, refer to the documentation inside the evm folder

ANTELOPE

delphi.bridge.cpp

The bridge's Antelope contract, it gets notified of new request on the EVM contract by listeners, then it checks out the request and imports it, finally it queries the relevant data and sends it back to the EVM contract using eosio.evm

TESTNET : delphibridge

MAINNET : TBD

To learn how to deploy it, refer to the documentation inside the antelope folder

LISTENERS

The listener for this bridge is located inside our Telos Oracle Scripts repository
