:
0x7f11f79DEA8CE904ed0249a23930f2e59b43a385

, is the USDB address on the Blast Sepolia Testnet L2. You might need to wait a little bit before your L1 bridge transaction takes effect on the L2. Once it’s been included, you can query your USDB balance via:
0x4300000000000000000000000000000000000003
