Decentralized Apps (dapps)

Activity in Web3 is done with something called decentralized apps or dapps.
Most dapps don't even require payment to get started; I'll point out ones where payment is needed.

Firefly: Social Crossposting

Firefly is an app that allows you to post to multiple social media accounts at once.
Bluesky, Twitter, Lens, and Farcaster are supported.

Yup is free. However, Farcaster profiles require payment to create.

The Lens Protocol: Social Onchain

The Lens Protocol is a social network protocol that hosts many apps that all work with each other.
You create a profile on the Lens website (https://lens.xyz), but you post from apps like Hey and Orb.

Joining Lens used to cost money, but it is now free.
Most actions on the Lens Protocol are free. Collecting posts with a pricetag or Super Following will cost money.

Farcaster: More Web3 Social

Farcaster is another onchain social network that is completely different from Lens.
The mobile app used to be called Warpcast, but now the main website moved to farcaster.xyz and the mobile app is called Farcaster.
However, you can use other apps such as Firefly to post to Farcaster.

I don't know how much it costs to join Farcaster now. It may be free or paid.

Mirror: Blockchain-based Blogging

Mirror is a blogging platform based on a blockchain called Arweave.
It has a clean interface, collectible posts, and the ability to subscribe to (follow) blogs you like.

Collecting an entry costs money (most commonly 0.00069 ETH, about $3). Creating entries is free.

More dapps

Ethereum.org has a list of dapps that you can look at.
Contrary to what it says, you don't always need any ETH (or other cryptocurrency) to get started.
Coinbase also has a list of dapps that is more comprehensive than Ethereum.org's list.

Want to add a dapp?

If you're a crypto user who wants me to try a dapp (preferably a free-to-start one), then you can message me.
I accept messages on Discord (littlebit670), Twitter, and Matrix.
