Build on Sei with AI

Action required: IBC assets on Sei will become inaccessible If you hold USDC.n (USDC via Noble), USDT.kava (Kava USDT), Wormhole-bridged tokens, or any other IBC asset on Sei, you must swap, migrate, or bridge out before the governance proposal to disable inbound/outbound IBC transfers passes and is activated to avoid permanent loss of access. After this, Sei will no longer support IBC bridging of assets from Cosmos-based chains to and from Sei Network. Consult the SIP-03 Migration Guide for the full list of affected assets, required actions, and supported routes. For USDC.n specifically, see: Holders of USDC.n Need to Swap or Migrate.

AI coding assistants are powerful — but they weren’t trained on Sei’s specifics. Without context, they’ll give you generic Ethereum answers: wrong gas patterns, missing dual-address handling, outdated package names, and assumptions about finality that don’t hold on a 400ms chain. Sei provides two complementary tools to fix this.

Two tools, two roles

sei-skill

Knowledge injection. Teaches your AI assistant everything about Sei — architecture, precompiles, wallet patterns, gas behavior, and ecosystem — so every answer it gives is Sei-specific from the start.

MCP Server

Live blockchain access. Gives your AI assistant tools to read and write on-chain: query balances, send transactions, interact with contracts, and monitor network state in real time.

Use them together: sei-skill makes your assistant think in Sei, the MCP Server lets it act on Sei.

Build AI agents on Sei

Cambrian Agent Kit

SDK for building autonomous AI agents with DeFi integrations — staking, lending, swaps, liquidity — powered by LangChain.

Agentic Wallets

Wallet infrastructure designed for AI agents: programmable signing, session keys, and policy controls.

x402 Payments

HTTP-native micropayments so agents can pay per-inference for LLM APIs, data feeds, and other monetized services.
