    Many users are reporting that their swaps and transactions are stuck. We have identified an issue with Unichain's proxy where it is not forwarding transactions to our TEE builder.

    Investigating

    We have noticed that many transactions are getting stuck within Unichain Mainnet's mempool and are subsequently not being added to newly produced blocks. This means user swaps and regular transactions are not being submitted to the chain.
