Architecture

Installation

To deploy the Tezos price oracle you can use the Ligo IDE online

You will need yarn or npm installed.

    git clone https://github.com/protofire/tezos-price-oracle
    cd tezos-price-oracle
    yarn

Poster Script

The poster is a simple centralized application created with oclif, that reads from coingecko the prices of Tez and Bitcoin and post them to the blockchain.

Running

The poster command requires some arguments to run:

• ORACLE_ADDRESS: The oracle address where the contract is deployed.
• TEZOS_RPC: a Tezos public rpc.
• Some properties from a wallet: MNEMONIC, SECRET, PKH, PASSWORD, EMAIL, to be used as a signer. This wallet must be whitelisted by the oracle contract. You can download some faucet from here.

MNEMONIC="MNEMONIC" SECRET="SECRET" PKH="PKH" PASSWORD="PASSWORD" EMAIL="EMAIL" TEZOS_RPC="https://api.tez.ie/rpc/carthagenet/" ORACLE_ADDRESS="ORACLE_ADDRESS"  ./bin/run assets
