Lets an agent execute an onchain transaction without needing its own wallet to already hold that chain's native <a href="https://claude-me.com/en/glossary/core-concepts/token/" target="_blank" rel="noopener">Token</a> (ETH on Ethereum, SOL on Solana) to pay the fee — instead paying directly in a <a href="https://crypto-bible.com/en/glossary/defi-basics/stablecoin/" target="_blank" rel="noopener">Stablecoin</a>, or having a third party cover the fee. This removes "do I have the right native token to pay the fee" — a chore unrelated to the transaction's actual purpose — from the list of problems an agent has to deal with.

Slippage Tolerance is the maximum percentage by which an Agent's actual execution price is allowed to deviate from the expected price when executing an on-chain transaction — set too tight, transactions frequently fail from normal market fluctuation; set too loose, transactions become exploitable by <a href="https://defai-bible.com/en/glossary/mev-arbitrage/mev/" target="_blank" rel="noopener">MEV</a> attackers, executing at a price far worse than expected. It's a parameter every automated on-chain transaction must explicitly set.
