Signature verification

All prices saved in Limestone have a signature, thanks to which you always can verify if the price data has been submitted by the trusted provider.

Enable signature verification

To enable signature verification you can set verifySignature option to true in getPrice, getHistoricalPrice or getAllPrices methods. If signature is invalid - error will be thrown.

const price = await limestone.getPrice("AR", {
  verifySignature: true,
});
console.log(price.value);
