What problem does it solve? Managing a self-custody crypto wallet across multiple chains (X Layer, EVM, Solana) requires juggling authentication, balance queries, token transfers, transaction history, and smart contract interactions. This Skill turns those operations into natural-language commands executed through the OKX onchainos CLI with TEE-based signing. ## Core Features & Use Cases - Wallet Authentication & Accounts: Email OTP or API Key login, account creation, switching, status checks, and logout, with locale-aware verification flows. - Balances & Transfers: Query authenticated balances per chain or token, send native and ERC-20/SPL tokens with simulation checks and confirmation handling. - Contract Calls & Signing: Execute non-swap smart contract calls with optional MEV protection, and sign messages via personalSign (EVM + Solana) or EIP-712 (EVM only). - Use Case: Ask "send 100 USDC to 0xAbc on Base" — the Skill resolves the chain ID, validates the recipient, runs pre-execution simulation, handles any confirmation prompt, and broadcasts the transaction with TEE signing. ## Quick Start Ask the agent to show your wallet balance or send a specific amount of a token to an address on a named chain, and it will handle login, chain resolution, and execution.
