# Sei Documentation

> Technical documentation for Sei, the fastest EVM blockchain. Covers smart contract development (Hardhat, Foundry), frontend integration (wagmi, ethers.js), AI tooling (MCP Server, Cambrian Agent Kit), x402 micropayments, node operations, and the Sei Giga upgrade roadmap.

Sei is a parallelized EVM Layer 1 blockchain with 400ms finality, 100 MGas/s throughput, and full Ethereum tooling compatibility. Deploy standard Solidity contracts with no modifications. Chain ID: mainnet 1329, testnet 1328.

Prerequisites: Node.js ≥ 18, a wallet (MetaMask or any EVM-compatible wallet), and SEI tokens for gas fees.
Authentication: No API key is required for public RPC endpoints. Rate limits apply to free RPC endpoints — use a dedicated provider (Ankr, DRPC, Nirvana) for production workloads.
Version compatibility: Solidity ≥ 0.8.x recommended. Sei EVM uses the Pectra EVM version (without blob transactions).
Network requirements: Mainnet chain ID 1329, testnet chain ID 1328. Gas is paid in SEI (18 decimals).
Important notes: Sei has 400ms block times — set lower polling intervals than on Ethereum. Transactions that touch independent state are parallelized automatically; shared-state writes are serialized.

## Learn

Sei is a parallelized EVM Layer 1 blockchain. Its performance comes from Twin Turbo Consensus (optimistic block processing), parallel EVM execution (concurrent transaction processing for independent state), and SeiDB (high-throughput storage layer). Full Ethereum tooling compatibility — deploy standard Solidity contracts with no modifications.

Sei Giga is the next major upgrade targeting 200K TPS and 5 gigagas/s throughput via Autobahn multi-proposer BFT consensus and a custom EVM execution engine. For developers: Sei Giga's parallel execution engine rewards contracts with user-scoped state (mapping per address) over shared global state.

Mainnet (pacific-1): Chain ID 1329. Testnet (atlantic-2): Chain ID 1328.

## EVM Development

Sei's EVM is fully compatible with Ethereum. Standard Solidity contracts deploy without modification. All Ethereum tooling (Hardhat, Foundry, wagmi, ethers.js, viem, RainbowKit) works as-is. Transactions touching independent state execute concurrently.

Precompiled contracts at fixed addresses expose native Sei functionality (staking, governance, IBC transfers, pointer contracts) to EVM.
