# Sei Documentation

> Technical documentation for Sei — a parallelized EVM Layer 1 with sub-second finality, full Ethereum tooling compatibility, and a clear roadmap toward Sei Giga (200K TPS, 5 gigagas/s).

Sei is a parallelized EVM Layer 1 blockchain with 400ms finality, ~100 MGas/s throughput today, and full Ethereum tooling compatibility. Deploy standard Solidity contracts with no modifications. Chain ID: mainnet 1329, testnet 1328. The next major upgrade, Sei Giga, targets 200K TPS via Autobahn multi-proposer BFT consensus and a custom EVM execution engine.

Prerequisites: Node.js ≥ 18, a wallet (Compass, Rabby, MetaMask, or any EVM-compatible wallet), and SEI tokens for gas.
Authentication: No API key is required for public RPC endpoints. Rate limits apply — use a dedicated provider (Ankr, DRPC, Nirvana) for production workloads.
Version compatibility: Solidity ≥ 0.8.x recommended. Sei EVM tracks the Pectra EVM (without blob transactions).
Network requirements: Mainnet chain ID 1329 (pacific-1), testnet chain ID 1328 (atlantic-2). Gas is paid in SEI (18 decimals).
Important notes: Sei has 400ms block times — set lower polling intervals than on Ethereum. Transactions touching independent state are parallelized automatically; shared-state writes are serialized.
IBC deprecation: Per SIP-03, inbound/outbound IBC transfers are being disabled. Holders of IBC assets (USDC.n, USDT.kava, Wormhole-bridged tokens) must migrate before the governance proposal activates — see /learn/sip-03-migration.

## Learn

Sei is a parallelized EVM Layer 1 blockchain. Performance comes from Twin Turbo Consensus (optimistic block processing), parallel EVM execution (concurrent transactions on independent state), and SeiDB (high-throughput storage). 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 via Autobahn multi-proposer BFT consensus and a custom EVM execution engine. For developers, Sei Giga's parallel 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.

SIP-03 migration: inbound/outbound IBC transfers are being disabled. Holders of IBC assets must swap, migrate, or bridge out before the governance proposal activates.

## 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, JSON, oracle, p256) to EVM.

## Node Operations

Sei supports full nodes (recent state, consensus relay), archive nodes (complete historical state), and validator nodes (block production and consensus). StateSync enables fast bootstrap — new nodes fetch a recent state snapshot instead of replaying all historical blocks. The Sei Giga storage migration moves nodes to a new format optimized for the upcoming throughput targets.

## Examples

### Deploy a contract with Hardhat

```javascript

module.exports = {
  solidity: "0.8.26",
  networks: {
    sei: {
      url: "https://evm-rpc.sei-apis.com",
      chainId: 1329,
      accounts: [process.env.PRIVATE_KEY],
    },
  },
};
```

### Query a balance with viem

```typescript
import { createPublicClient, http } from "viem";
import { sei } from "viem/chains";

const client = createPublicClient({ chain: sei, transport: http() });
const balance = await client.getBalance({
  address: "0xYourAddress",
});
console.log("Balance:", balance);
```

### Connect a wallet with wagmi

```typescript
import { http, createConfig } from "wagmi";
import { sei } from "wagmi/chains";
import { injected } from "wagmi/connectors";

export const config = createConfig({
  chains: [sei],
  connectors: [injected()],
