Nope! We do not currently have an Alchemy token sale but our users will be the first to know if we ever do ;)
Alchemy is currently a private company, if you are interested in investing please reach out to [email protected]
If you are completely new to the blockchain space, you should check out our Blockchain 101 guide to learn more about the ins and outs of the technology behind blockchain, and the advantages of decentralization.
If you already know some blockchain stuff and are ready to dip your toes in development here are three great tutorials to check out:
No, we will never store your private keys.This also means we cannot sign and send transactions for you. For help on how to send transactions using Alchemy, check out this guide.
Generally "already known" means the transaction is on the node and is in a pending state. A good solution here is to double check that your transaction nonces are correct and that there aren't any currently pending transactions in your mempool.
If you run into your capacity limit, we recommend switching on autoscale which will allow your app to continue functioning with on-demand compute.
Archive data is free and available for all of our customers, no additional set up necessary!
You can! While we don't allow a single email to be on multiple teams due to UX concerns, one thing you can do is invite the user by appending a + to their email. For example, a user with email [email protected] could use [email protected] and [email protected] to be on two different teams, while still getting all their emails to one inbox!
In order to ensure maximum reliability for your calls, you can make
eth_getLogs requests with up to a 2K block range and no limit on the response size. You can also request any block range with a cap of 10K logs in the response.
If you need to pull logs frequently, we recommend using WebSockets to push new logs to you when they are available.

Glad you asked! We've built a bunch of higher level APIs to make your life as an Ethereum developer much easier. With our enhanced APIs you can access things like token balances and information, transaction history for given addresses, notifications about transaction activity, and more. Check out the full list here.
Alchemy's servers are currently located on US East, however we serve production traffic from 99% of countries in the world and see great latency in all regions.
Alchemy currently supports Geth and OpenEthereum node clients.
We do support compressed response payloads by using a Content-Encoding of gzip on all our responses.
Compute units are a way of measuring the resources it takes to serve your traffic, we implemented this to make sure pricing is sustainable and cost-effective as you scale. Check out this blog post for the reason we decided to implement a compute unit system.
You can see a breakdown of each method and its associated compute unit here.
A super easy way to distinguish between these two addresses is by calling eth_getCode, which will return contract code if it's a contract and nothing if it's a wallet. Here's an example of both using our composer tool:
Don't worry, we got you. Check out our support page for plenty of options!
