Sign ethereum takes too long

[Nahatakyan]

Hi everyone.
I want to integrate WalletConnect into my app and have a problem. I receive a request with the method eth_sendTransaction, sign it (using web3swift), and send back the hash value. But pancakeswap shows eternal loading and app.1inch.io shows that the transaction is signed, then eternal pending. I did open a web3swift issue, and they say, that I need to add a transaction in the chain. In your examples not show how to do that. In the V2 example, there is the example to sign transaction and there is no written how to add it to the chain.
Can someone help me?
