-Web3Auth is composable - you can combine it with meta-transaction flows, multisigs, and other cryptographic protocols. It is easy to build on top of,
-and generally fits in with most other technology stacks, including but not limited to; your favorite scalability solutions, meta transactions, smart
-contract wallets, different elliptic curve pairs and even RSA.

+Faucets are services that provide users with a small amount of cryptocurrency for free. These are
+often used for testing purposes or to onboard new users to a blockchain network. Here are some
+popular faucet services for different test blockchains:
