This repository provide a small package to send prices feeds to the vega network using the open oracle format.
The code doing so is located under the /prices folder, and exposes a Prices type and a single public method named Send.
The requirement to use this package are:
- a vega wallet mnemonic
- an ethereum private key (hex formatted)
- the address of a vega node on the network with the grpc API enabled.
The Prices type will do the following:
- convert the price inputs into the open oracle using sign the payload, and return using the
code.vegaprotocol.io/oracles-relay/openoraclepackage. - a valid OracleSubmission transation is then built
- then emitted to the vega network using the wallet specified.
A demonstration binary is available at the root. It can be installed using go 1.20.x.
$ go install github.com/jeremyletang/vega_openoracle_demo
A configuration is required to run it, here's an example:
node_addr = "n06.testnet.vega.xyz:3007"
ethereum_private_key = "0xd58575992709768084bf898fcafbb07d25746c566f53a75ee428708833677d2b"
wallet_mnemonic = "elder december include distance diary pizza bean churn fatigue repeat museum hello unfair march always loyal million video maple rich illegal industry borrow coral"
Assuming this configuration is save in a file name config.json, we could send price to vega with the following command:
$ vega_openoracle_demo -config=config.json -price=3354500 -timestamp=1699613159 -asset=BTC
