Owlracle's bots were designed to empower your DAO or community by providing easy access to our gas endpoint with a simple chat command

• • What is Owlracle?
  • Owlracle is an open-source gas oracle running predictions for multiple blockchain networks. We provide a website and an API for retrieving Owlracle's information, giving dapp developers easy access to gas information. Check our Medium article explaining that in details.
• • How do you make the gas predictions?
  • This tool attempts to predict the gas to be paid on multiple chains by averaging recent past transactions. For each block, we take the mined transaction with the lower gas. Every speed is measured by calculating the minimum gas paid to be accepted on a given percentage of past blocks. Take into consideration that the numbers shown are just estimations. Check our Medium article explaining that in details.
• • How do you predict the gas fee?
  • We scan the last N (default 200) blocks and check the minimum gas accepted on a transaction for each block. Then we calculate how much gas you should pay to be accepted on X% (varying by speed) of these blocks.
• • I like your service. When will you come to my favorite network?
  • We are constantly evaluating the benefits of adding new networks to our oracle. In general, we try to priorize networks with a good amount of monthly transactions and/or trending ones. If you feel we are missing a promising network, feel free to contact us and share your opinion.
• • I like your website, but I wish there was a more convenient tool. Like a browser extension.
  • Weel, there is! You can go to Chrome Web Store and download our extension. It is super easy, one click and you get gas/history from your favorite network.
• • I would love to get Owlracle's predictions on my community group. Do you have anything for that?
  • Sure we do! You can integrate our Telegram bot or Discord bot bots directly into your groups, so your people can easily get Owlracle's predictions.
• • I saw tweets from Owlracle about gas. How can I get it to send me gas for my favorite network?
  • You just have to make a tweet mentioning @0xOwlracle, use the hashtag #gas and the name/token of your favorite network. e.g. polygon, ftm, bsc, etc.
• • My app have thousands of users making requests to your API. The API limit seems too low.
  • You should never call our API from the frond-end. Schedule your server to retrieve information at time intervals of your choice, then when your users request it, just send the cached data to them.
• • Shouldn't I be worried if users peek into my app's source-code and discover my API key?
  • Do not EVER expose your API key on the front-end. If you do so, users will be able to read your source-code then make calls using your API (thus expending all your credits). Retrieve our data from your server back-end, then provide the cached data to your users when they request it.
• • My API key have been exposed. What should I do?
  • You can reset your API key hash and generate a new one clicking here.
• • I am reaching API rate limit. How can I make a recharge and keep using Owlracle?
  • On the header there is a place where you can login with your API key. After the login, you can click on Recharge key option. From there you will be asked to connect your Metamask wallet. Then you can transfer any amount of tokens to recharge your key.
• • I need to retrieve gas info for several chains. Do I need to make a recharge on every network?
  • No! Once you recharge your key, the current token price is converted to USD and stored on your API key account as credit. Every time you request our endpoints (past the free limit) credit is subtracted from your API credit, regardless of which tokens were used when recharging the key. The current token price does not matter either, as they are converted to USD at the time of the recharge.
• • I see some other services using the mempool for getting gas price estimations. How is Owlracle better?
  • As you probably already know, Owlracle uses statistics built upon recent past data to build its estimations, not the mempool. Both methods are suitable, and each carries its own strengths and weaknesses. Using mempool for gas price prediction is good because you get data before they are in the chain. Still, it is also not optimal because of two main factors: The mempool is subject to change. Bots can spoof the mempool manipulating txs in there. Another factor is that the mempool is local data, each node has its own, so information may differ significantly from one node to another.
