Safer Solidity contracts and wallet-connected UIs.
Smart contract development
Blockchain & web3 skills for AI agents
Software for public chains, from the contracts to the apps around them. Most Skills write and test Solana programs and Ethereum contracts, some against a copy of mainnet state; others read chain data, follow wallets, manage DeFi positions and add wallet sign-in to an app.

Smart contract development
Only if you give it a wallet or key that can sign. Skills that send transactions ask for that access explicitly; most development Skills work against test networks or local copies of a chain.
A contract that passes on an empty test chain can still fail against real balances and real contracts it calls. Running it against a copy of mainnet catches those cases before the contract is deployed and can no longer be changed easily.
