ETH6900 is built as an EVM-compatible protocol that runs across Ethereum and its Layer-2 (L2) scaling networks. Its architecture ensures seamless operation wherever the Ethereum Virtual Machine is supported — meaning it can optimize transactions across multiple chains without any special setup or migration.

Without forking or alter existing networks. ETH6900 integrates natively at the RPC layer, acting as a transparent middleware between wallets and nodes. This makes it instantly usable by any EVM-based project — from Ethereum mainnet to emerging L2s like Base, Optimism, and Arbitrum.

Supported Networks

ETH6900 initially focuses on Ethereum Mainnet and leading Layer-2 environments where gas efficiency and transaction speed vary the most.

Each RPC endpoint is backed by a dedicated optimization engine that handles:

• BaseFee monitoring

• Deadline-based scheduling

• Private relay routing

• Savings calculations

Multi-Chain Synchronization

ETH6900 uses a unified engine that monitors gas metrics across supported networks in parallel. This multi-chain awareness enables cross-network analytics (e.g., comparing gas trends between Ethereum and Optimism) and dynamic scaling of relayers based on real-time congestion.

The system is composed of two primary modules:

graph TD
A[User Wallet] --> B[ETH6900 RPC]
B --> C[Gas Engine]
C --> D[Private Relay]
D --> E[Blockchain Network]
C --> F[Multi-Chain Monitor]

• Gas Engine → handles scheduling, fee forecasts, and broadcast logic.

• Private Relay → sends transactions directly to builders, skipping public mempools.

• Multi-Chain Monitor → collects live gas data from multiple chains to optimize performance per region.

Chain-Agnostic Design

ETH6900’s EVM compatibility means:

• No redeployments – no need to fork or wrap contracts.

• Native Support – works directly with existing EIP-1559 mechanics.

• Upgradeable via Configs – new chains can be added by publishing a new RPC URL, not rewriting code.

Example:

{
  "chainId": 8453,
  "network": "Base",
  "rpcUrl": "https://rpc.eth6900.io/base",
  "deadlinePolicy": "default",
  "mevProtection": true
}

This modular configuration makes ETH6900 lightweight, scalable, and easy to integrate across the Ethereum ecosystem.

Cross-Chain Expansion Plan

As new L2s emerge, ETH6900’s plug-in architecture will allow automatic onboarding through a single configuration push, ensuring rapid network adoption without downtime.

Chain Health & Monitoring

Each supported chain is continuously monitored through ETH6900’s internal Health Matrix:

This matrix ensures network reliability while maintaining predictable transaction performance across all supported environments.

Interoperability Goals

ETH6900’s multi-chain structure prepares it for deeper integrations:

• Cross-chain gas routing — allowing users to broadcast from one L2 while ETH6900 optimizes fees across others.

• Bridge Compatibility — native coordination with bridge contracts for low-fee transfers.

• Chain-Specific Heuristics — each engine learns the behavior of its network to tailor broadcast timing more precisely.

These capabilities make ETH6900 a multi-network gas brain, evolving from a single-chain optimizer into a universal fee intelligence layer for Web3.

The Blockchain Layer defines ETH6900’s identity as a chain-agnostic, EVM-native protocol that scales horizontally across Ethereum’s ecosystem.
By integrating through RPC endpoints instead of contracts, ETH6900 remains flexible, fast to deploy, and lightweight — making it the easiest optimization layer to integrate for both users and developers.
