If the bridge from USDC on Solana to USDC.e on Polygon failed, it could be for a number of reasons including the Solana wallet provided not having enough SOL to complete the transaction (we try to front that for our users).
Note that your funds are never lost though, you can retrieve them at any time by getting your Solana private key using /export.
I just see “buy” and “sell”. Are these market or limit orders?
At the moment, we only support market buys and sells.
With Polymarket, technically all orders are represented as “limit” orders so market orders are really orders executed at the best available price. Note that this may result in less favorable fills on markets that are lower volume.We plan on supporting explicit limit orders in the future. Stay tuned.
