If you are unable to broadcast your transaction or proceed with a swap, you might need to deploy your wallet.
In order to deploy your Crystal Wallet, you will need a few TON (at least 1.1 TON for deployment itself).
You can buy TON there with crypto:
https://cex.io/ (USD, USDT)
https://www.coineal.com/ (BTC)
https://kuna.io/ (USDT)
http://mexc.com (USDT)
Once you have the TON on your wallet, you can press the Deploy button.
Confirm the transaction
You can then use your wallet to send funds
