# Tezos price oracle
The Tezos Price Oracle receives price updates from a centralized poster, who pulls the prices from coingecko.
## Contracts
### Oracle:
- [Better call dev link](https://better-call.dev/bigmap/carthagenet/KT1WBqqaCzh8MVD65fvL2CHmEJGrNahHRw4A)
- [Contract in the Ligo IDE online](https://ide.ligolang.org/p/KlnD-FsYFR4UbYWlV3mNlA)
### Inspector:
- [Better call dev link](https://better-call.dev/bigmap/carthagenet/KT1XqUyWpK5Dc97E2NUtdfVo3n1hwxoTbd6r)
- [Contract in the Ligo IDE online](https://ide.ligolang.org/p/H_Kj28bncDwsBGKr-wJg2Q)
## Architecture
## Installation
To deploy the Tezos price oracle you can use [the Ligo IDE online](https://ide.ligolang.org/p/ceSGJQnxzT7VreZbRshyJA)
You will need [yarn](https://yarnpkg.com/lang/en/docs/install/) or [npm](https://docs.npmjs.com/cli/install) 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](https://faucet.tzalpha.net/).
```
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
```

For any concerns with the oracle, please open an issue
