Best for

Consumer crypto apps
Onchain social and creator products
Low-cost EVM application deployment

Tradeoffs

Sequencer and bridge assumptions differ from Ethereum mainnet
Some infrastructure support is younger than on Ethereum mainnet

Build on Base

Intents scoped to this chain, with per-chain stacks, exclusions, and risks.

ship a consumer app on Base — zerodev, x402, uniswap, chainlink

Chain readiness

Per-chain readiness ranks how well each protocol's support on Base is evidenced — a cited, addressed deployment outranks a protocol that only lists the chain.
