Battle-Tested Infrastructure

Premium RPC providers (Alchemy, Infura), tier-1 auditors (Trail of Bits, OpenZeppelin), and proven operational excellence.

Institution-Grade Security

We implement security-first development: comprehensive testing (unit, integration, fuzzing with Echidna), multiple audits from tier-1 firms (Trail of Bits, OpenZeppelin, Consensys Diligence), formal verification for critical components using Certora, and conservative launch strategies with TVL caps.

Every line of code assumes adversarial conditions.

DeFi Composability Expertise

Ethereum's killer feature is composability.

We architect protocols that integrate deeply with existing DeFi: source liquidity from Uniswap/Curve, use Aave for leverage, integrate Chainlink oracles, and compose primitives in novel ways.

We understand how to build on top of $50B in existing infrastructure.

Advanced Gas Optimization

Every opcode matters on mainnet where gas costs range from $5-50+ per transaction.

We implement custom assembly for critical functions, packed storage layouts, minimal state modifications, efficient data structures, and batch operations.

Our optimizations save users millions in gas costs over protocol lifetime.

Governance & DAO Implementation

Ethereum hosts the most sophisticated DAOs managing billions in treasuries.

We implement OpenZeppelin Governor contracts, multi-sig operations with Gnosis Safe, timelock controls, hybrid on-chain/off-chain voting with Snapshot, and operational frameworks proven to manage $100M+ safely.

Institutional Integration

We implement features institutions require: integration with custody solutions (Fireblocks, Anchorage, BitGo), compliance hooks for permissioned pools, detailed on-chain analytics, operational controls, and documentation meeting enterprise standards.

Building bridges between DeFi innovation and institutional capital.

Upgrade Patterns & Long-Term Maintenance

Unlike easily upgradeable L2s, mainnet upgrades require extreme caution.

We implement transparent proxies, UUPS patterns, and diamond standard where appropriate—always with multi-sig governance, timelock delays, and emergency pause mechanisms.

Building for decade-long operational timelines.

Why Ethereum Mainnet? The Gold Standard for Blockchain Security

Ethereum Mainnet remains the most decentralized, most secure, and most trusted blockchain in existence. With over $50 billion in Total Value Locked and 8+ years of continuous operation without network downtime, Ethereum has proven itself as the infrastructure for applications handling real economic value. While Layer 2s offer lower fees, Ethereum Mainnet provides something money can't buy: absolute confidence that your protocol will be secure, decentralized, and operational for decades.

The security guarantees are unmatched. Ethereum's Proof of Stake consensus secures the network through over 1 million validators and $100+ billion in staked ETH—making it economically impossible to attack. This security isn't theoretical—major institutions, nation-states, and trillion-dollar financial systems are building on Ethereum precisely because of this proven security model. For protocols managing billions in assets, Ethereum's security premium over alternatives isn't just worth it—it's required.

What makes Ethereum exceptional is network effects and composability. The deepest DeFi liquidity exists on Ethereum. The most sophisticated financial primitives—Uniswap, Aave, Maker, Curve—are battle-tested on mainnet. Building on Ethereum means instant access to this composability: integrate with proven protocols, tap into massive liquidity pools, and leverage infrastructure that's been stress-tested through multiple market cycles.

Frequently Asked Questions

Why build on Ethereum Mainnet when L2s have lower fees?

Ethereum Mainnet provides security, decentralization, and trust that L2s cannot match. With 1M+ validators and $100B+ in staked ETH, mainnet offers economic security essential for high-value protocols. For applications managing $100M+, the security premium justifies higher gas costs. L2s are centralized with small validator sets—fine for low-value transactions, inadequate for institutional capital.

How expensive is it really to use Ethereum Mainnet?

Gas costs range from $5-50+ per transaction depending on network congestion. This makes mainnet unsuitable for frequent microtransactions but perfect for high-value operations: deploying $100M lending pools, executing $10M governance decisions, or minting blue-chip NFTs. The cost per transaction is negligible compared to value secured. We optimize contracts to minimize gas costs where possible.

How long does a mainnet audit take and what does it cost?

Tier-1 audits (Trail of Bits, OpenZeppelin, Consensys Diligence) typically take 3-4 weeks and cost $50-150k depending on codebase complexity. For institutional protocols, we recommend 2-3 audits from different firms plus ongoing bug bounties. This is expensive but essential—a single exploit can cost more than years of audit fees. Audits are the price of legitimacy.

What's the difference between transparent proxies and UUPS?

Both enable contract upgrades. Transparent proxies have upgrade logic in the proxy itself—simpler but higher gas costs. UUPS puts upgrade logic in implementation contracts—more gas-efficient but requires careful implementation. For high-value protocols, we use transparent proxies for critical contracts (safety over gas costs) and UUPS for frequently-used contracts (gas optimization). Always with multi-sig governance and timelocks.

How do you handle MEV on Ethereum Mainnet?

MEV (Maximal Extractable Value) is sophisticated bot activity extracting value from transactions. We implement MEV-resistant patterns: batch operations to reduce arbitrage opportunities, use Flashbots RPC for sensitive transactions (private mempools), design tokenomics accounting for MEV, and implement slippage protections. MEV is a reality on Ethereum—smart protocol design works with it rather than against it.

Should we launch on mainnet or L2 first?

Depends on your use case. Launch on mainnet if: managing $50M+ in value, requiring maximum security/decentralization, targeting institutional capital, or building blue-chip NFTs. Launch on L2 if: targeting retail users, needing frequent transactions, building games/social apps, or testing product-market fit. Many protocols launch high-value components on mainnet while expanding to L2s for user acquisition.

What custody solutions integrate with Ethereum Mainnet?

All major institutional custody providers support Ethereum mainnet: Fireblocks (transaction management and MPC custody), Anchorage Digital (regulated custody), BitGo (multi-sig custody), Copper (prime brokerage), and Coinbase Custody. These integrations enable institutions to use DeFi protocols while maintaining custody standards. We implement contract patterns compatible with these custody solutions.

How do you optimize gas costs on mainnet?

We use multiple optimization techniques: packed storage (combine multiple variables into single slots), custom assembly for critical functions, minimal state modifications (prefer memory over storage), efficient data structures (mappings over arrays), batch operations, and caching read values. We also optimize calldata (use bytes over strings), implement view functions for reads, and design contracts to minimize cross-contract calls. Gas optimization is an art and science.
