vToken APIs

There are three ways to query vToken exchange price:

1. Use the Bifrost Runtime API, which is the most up-to-date and accurate method.

2. Call EVM contract on Moonbeam.

3. API for Frontend (with more vToken related storages)

Bifrost Runtime API

https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Fbifrost-polkadot-rpc.dwellir.com#/runtime

vtokenMintingRuntimeApi

1. getCurrencyAmountByVCurrencyAmount

2. getVCurrencyAmountByCurrencyAmount

As the showcase above, token2:0 is DOT and vtoken2:0 is vDOT on Bifrost Polkadot, getCurrencyAmountByVCurrencyAmount is to input vDOT amount (with decimals) to query the exchange price in DOT.

Check the Token indexs via here.

EVM contract on Moonbeam

Query the exchange rate from SLPx contract on Moonbeam:
