No custody. No lingering allowances.
EIP-5792 lets a wallet be asked to process a batch of calls in one step; Arc supports EIP-7702 so an ordinary wallet can do this without migrating to anything new. ONCE's own worker watches your condition against indexed pool data, and when it fires it assembles the whole trade — approval and swap together — behind a single signature request. Arc quotes gas in USDC, not Gwei, so the cost is a real number before you arm anything.
