Best for
- Settlement and high-value contracts
- Canonical token liquidity
- ENS and other mainnet-native primitives
Tradeoffs
- Higher gas costs than L2s
- Mainnet deployment mistakes are expensive to recover from
Build on Ethereum Mainnet
Intents scoped to this chain, with per-chain stacks, exclusions, and risks.
- build a privacy-first app on Ethereum mainnet — railgun, semaphore, maci, fluidkey
Chain readiness
Per-chain readiness ranks how well each protocol's support on Ethereum Mainnet is evidenced — a cited, addressed deployment outranks a protocol that only lists the chain.

| 81 | Coinbase AgentKit Coinbase Developer Platform toolkit for giving AI agents a crypto wallet and onchain capabilities — wallet management plus composable actions across protocols, framework-agnostic (LangChain, Vercel AI SDK, and others). |
Agent wallets Agent-controlled funds require explicit spend limits, allowlists, and key-management guardrails before production. |

| 84 | Ethereum Attestation Service Free and open protocol for making on-chain and off-chain attestations — structured, signed, verifiable records about anything — on EVM-compatible chains. |
Onchain & offchain attestations Onchain attestations are public; sensitive data must be kept offchain or hashed. |
