Ladder
1inch Aqua · SwapVM · Base

CEX-style grid on official Aqua. Rungs re-arm themselves.

WETH / USDC. Tokens stay in the wallet. A bid fill lights the ask with no maker transaction. WalletGuard and CoverageGuard sit in the program, so underfunded rungs stop quoting on-chain.

One ERC-20 allowance to Aqua. No session key. Spend ETH tomorrow and the asks go dark on their own.
A rung re-arms itself
Bid fills, virtual balance flips to ETH, the ask lights up. Round-trip profit is 2s. The taker paid the gas.
Quote-time floor, on-chain
Below your coverage floor the rung stops quoting. That is Aqua §3 as SwapVM bytecode, not a keeper.
