Showing wrong balance on blockchains

Today I noticed a discrepancy involving my crypto wallets.

When I opened my Trust Wallet, it showed a total balance of 0.4 BTC, even though I had approximately 0.5 BTC in my Coinbase Wallet.

Shortly after, I received a notification from Trust Wallet indicating that 0.05 BTC had been transferred, which I did not authorize or initiate.

Concerned, I proceeded to transfer my funds from Coinbase Wallet to my Wealthsimple account in three transactions:

• 0.002 BTC • 0.2 BTC • 0.3 BTC 

This totaled 0.5 BTC, which was successfully received by Wealthsimple.

However, when I checked Trust Wallet again, it showed three outgoing transactions totaling 0.4 BTC:

• 0.05 BTC • 0.12 BTC • 0.22 BTC 

These transactions match the 0.4 BTC balance that was initially displayed in Trust Wallet.

To verify, I checked both wallet addresses using a blockchain explorer. The results showed:

• Trust Wallet address: total of 0.4 BTC sent • Wealthsimple address: total of 0.5 BTC received 

This creates a discrepancy between what Trust Wallet reports and what was actually received in Wealthsimple.
