sei-skill is a structured knowledge base for AI coding assistants. Install it once and your assistant — Claude Code, Cursor, Copilot, Windsurf, or any other — will answer Sei questions with Sei-specific accuracy instead of generic Ethereum defaults.

​
Why this matters

AI assistants are trained on broad Ethereum knowledge, not Sei’s specifics. Without sei-skill, they’ll confidently give you wrong answers:
Without sei-skillWith sei-skill
maxFeePerGas in transactionsLegacy gasPrice (Sei doesn’t use EIP-1559 basefee)
“Finality takes ~12 confirmations”Instant finality — 1 confirmation is final
SSTORE costs 20,000 gasSSTORE varies: 72,000 on testnet, 20,000 on mainnet (governance-adjustable)
PREVRANDAO for randomnessPREVRANDAO is not random on Sei — use Pyth VRF or Chainlink VRF
Generic ERC-20 patternsSei precompiles, pointer contracts, dual-address UX

​
Three knowledge domains

sei-skill covers three areas. You can install all three or just the ones you need. Contracts — EVM smart contract development on Sei:
  • Foundry and Hardhat setup for Sei networks
  • All Sei precompiles (Staking, Governance, Bank, Distribution, JSON, P256)
  • Pointer contracts for cross-VM asset bridging
  • Gas optimization, OCC parallel execution awareness
  • Account abstraction (ERC-4337), contract upgradeability
  • Verification workflows on Seitrace
  • Security patterns and common errors
Frontend — dApp UI development:
  • Wagmi + Viem setup with Sei chain config
  • Wallet integration (Sei Global Wallet, MetaMask, Compass, Ledger, EIP-6963)
  • Dual-address UX (sei1... ↔ 0x... from the same key)
  • Fast-finality patterns for 400ms blocks
  • RainbowKit and ConnectKit integration
Ecosystem — infrastructure and integrations:
  • RPC endpoints (public, community, paid SaaS)
  • Bridges (LayerZero V2, Wormhole, Axelar, CCTP)
  • Oracles (Chainlink, Pyth, API3, RedStone)
  • Indexers (The Graph, Goldsky, Dune, Moralis)
  • DeFi protocols (DragonSwap, Yei, Takara, Saphyre)
  • Validators, node operations, grants

​
Quick install

git clone https://github.com/sei-protocol/sei-skill
cd sei-skill
./install.sh
This installs to ~/.claude/skills/sei/ by default (Claude Code). For other AI assistants, see the Installation Guide.
