This is cool and makes total sense! In practice(cowswap) inventory procurement probably happens post-auction-win. So no congestion Winners are responsible for submitting solutions on-chain. They can force the solution to post end-of-block giving their off-chain procurement time to settle. Timing games are fun

Furthmore - approved solvers (anyone who posts a bond) can use arbitrary smart contract interactions in solutions So solvers using off-chain procurement could fill with a smart contract that uses fallback liquidity (like an AMM) if the off-chain interaction didn’t settle in time. This removes slashing risk

2 questions: 1. “Winners… can force the solution to post end-of-block giving their off-chain procurement time to settle.“ can you elaborate more on this?? 2. For arbitrary SC, does that mean solvers could fulfil intent by making on-chain liquidity as the last resort in case of time out?

1. Yeah I oversimplified this Solvers get to choose *how* their solution makes it to chain So if they need a binance withdrawal to hit pre-solution - 1. If they’re a builder they can place the solution later in the block than the withdrawal (assuming the withdrawal makes that block) …
