Ethereum Mainnet
The canonical Ethereum settlement layer with the deepest liquidity, strongest neutrality, and highest execution costs.
Also available as JSON · Markdown
Resources
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.

Protocols supporting Ethereum Mainnet
| Ready | Protocol | Capability · caveat | Build | Status | Chains | Record |
|---|---|---|---|---|---|---|
| 100 | Chainlink Decentralized oracle network providing price feeds, verifiable randomness (VRF), automation, and cross-chain messaging (CCIP) to smart contracts. |
Data Feeds Push feeds update on deviation/heartbeat; consumers must check updatedAt for staleness. |

| 80 | ENS (Ethereum Name Service) Decentralized naming for Ethereum: human-readable names that resolve to addresses, contenthashes, and text records, with reverse (primary-name) resolution and cross-chain resolvers. |
Name resolution No known issue recorded yet. |

| 93 | Fluidkey Self-custodial privacy dApp for receiving, managing, and spending onchain funds through stealth-address smart accounts and a unified wallet interface. |
Stealth-address receiving UX Fluidkey stealth addresses provide unlinkability, not full untraceability by default |

| 89 | Helios Fast, secure, portable multichain Ethereum light client that turns an untrusted centralized RPC endpoint into a locally verifiable RPC for wallets and dapps. |
Local verifiable RPC Helios verifies RPC data but is not complete network anonymity |

| 87 | LayerZero Omnichain interoperability protocol for passing arbitrary messages and moving tokens between chains via on-chain endpoints and configurable verification. |
OApp messaging Security config (DVNs, executors) is the integrator's responsibility; defaults must be reviewed. |
