Introduction:

Having the best user experience in Web3 is the key. When we talk about Blockchain and EVM blockchains, people with no knowledge often say:

In the battle against the traditional financial system, developers of different protocols are trying to reduce the technical barriers for people with no tech knowledge. That's why ERC-4337 was born.

In simple terms, ERC-4337 allows users to bypass the barrier of paying gas fees from their own wallets or using their own ERC-20 tokens to cover the gas fees.

Furthermore, this enables stronger authentication methods, such as those commonly used with Google or Facebook, while we take advantage the capabilities of Web3. Additionally, users can easily recover their account passwords without the risk of losing their funds.

In this space, there are many available resources, and sometimes this can be overwhelming, or these solutions are tied to the providers. I will give you the best resource to start.

Let's talk about Candide.

Candide is an open-source solution for implementing ERC-4337. In this solution, you can recover your wallet, and it's free from third-party control.

For example, in this resource, you can learn how to send your first gasless transactions:
https://docs.candide.dev/wallet/guides/send-gasless-tx

You may have some doubts, i will clarify the next terms for you:

• Bundler: It's the equivalent of the Node because, thanks to this, we can group all user operations, and the bundler sends the transactions.

• RPC compatible with ERC-4337: In this space, we have different RPC providers, but the majority are not compatible with ERC-4337 methods because this change is relatively new, and companies need to evaluate how it grows before launching the feature.

  • But don't worry, Candide provides some examples of providers compatible with their tools.

• PayMaster: Are smart contract accounts that facilitate transaction sponsorship by permitting third-party-designed mechanisms to manage transaction costs.

After finishing the tutorial, you may ask: "How do I give the best things to my users?". The answer is QuickNode.
