Heads up if you trade crypto or finance up/down markets through the API.

On Friday Jun 5, we're changing how taker orders behave during the 250ms taker delay on these markets. Once your order clears initial validation and enters the delay window, it's locked in as pending until the delay finishes. What that means:
- You can't cancel an order while it's in the delay window. Cancel requests come back rejected with "can't be canceled because it is pending/delayed."
- The order's required balance is held during the delay, so other orders drawing on the same balance are checked against what's left until the delayed order clears.
- Resubmitting the same order while it's in the window will be rejected.
- Dropping the connection or canceling the client request after the order is in the delay won't stop it. It finishes processing once the delay completes.

Cancellation works the same as before everywhere else, and a taker-delayed order is still cancelable if part of it rests on the book.

[Polymarket Developers @PolymarketDevs]

New deposit wallets deployed from June 8 onwards will now use an architecture that lets us keep wallet security and maintenance up to date over time, so improvements and fixes reach everyone, without changing your wallet address or touching your funds.

Your existing wallets keep working exactly as they do today.

Prefer to manage upgrades yourself? You can opt out at the contract level.

For builders:
- SDK users: update to the latest clients, everything else is handled for you
- Direct API: the wallet address derivation changed; see the docs.
