-### L1 Testnets
+### Active Testnets (Recommended)
-- **Ropsten:** Ropsten played a significant role in Ethereum's history but was effectively deprecated by late 2022 when the Merge took place. The Merge marked the transition from proof-of-work to proof-of-stake consensus for the Ethereum mainnet. Ropsten's vulnerability to spam attacks and network instability made it unreliable for testing purposes.
+#### Base Sepolia (L2)
+Base Sepolia is the recommended testnet for all Base development. It settles on the Ethereum Sepolia L1 testnet and provides an environment for testing L2-specific features and smart contracts.
-- **Rinkeby:** Rinkeby offered better security than Ropsten and used a proof-of-authority consensus mechanism. However, it lacked decentralization and client diversity, which ultimately led to its decline in popularity. After the Merge, Rinkeby is no longer a recommended test network.
+#### Sepolia (L1)
+Sepolia is the primary stable testnet for Ethereum development. It is designed for developers seeking a lighter weight chain for faster synchronization and interaction. It is the preferred testnet for L1 development.
-- **Goerli:** Launched in early 2019, Goerli initially utilized a multi-client proof-of-authority consensus model to improve stability and security. Following the Merge, it transitioned to a proof-of-stake consensus mechanism, maintaining its cross-client compatibility and making it an ideal choice for developers. As of January 2024, Goerli is being sunset in favor of Sepolia.
+#### Optimism Sepolia (L2)
+Optimism Sepolia is built on the Ethereum Sepolia L1 testnet and offers a testing environment for Optimism's Layer-2 features.
-- **Sepolia:** As one of the two original primary testnets alongside Goerli, Sepolia is designed for developers seeking a lighter weight chain for faster synchronization and interaction. As of January 2024, it is now the preferred testnet and developers should migrate to using it.

+
+### Deprecated Testnets
+
+The following networks are deprecated and should not be used for new development:
-### L2 Testnets
+#### Goerli (L1)
+Launched in early 2019, Goerli was a popular multi-client testnet. As of January 2024, Goerli has been sunset in favor of Sepolia.
-- **Base Sepolia:** As new Layer-2 networks emerged that settled on Ethereum's Layer-1, the need for testnets dedicated to these L2 networks also arose. For instance, the L2 network Base has its own testnet, known as Base Sepolia. This testnet settles on the Ethereum Sepolia L1 testnet, providing an environment for testing L2-specific features and smart contracts.
+#### Ropsten (L1)
+Ropsten was deprecated in late 2022 after the Merge. It is no longer supported.
-- **Optimism Sepolia:** Optimism, an Ethereum Layer-2 scaling solution utilizing Optimistic Rollups, has its own testnet called Optimism Sepolia. This testnet is also built on the Ethereum Sepolia L1 testnet and offers a testing environment for developers to experiment with Optimism's Layer-2 features, smart contracts, and apps.
+#### Rinkeby (L1)
+Rinkeby was deprecated after the Merge and is no longer supported.
