Tracking L1 to L2 Native Deposits for Crypto Tax Reconciliation

GoldRush’s Multichain Transactions API addresses the challenge of tracking native asset deposits across blockchain layers for tax purposes by linking the L1 bridge initiation with the L2 finalization. When users bridge ETH from Ethereum to Layer 2 networks like Base, the activity spans two chains, requiring data providers to connect both sides of the transaction. Without this cross-chain linkage, tax platforms incorrectly treat the deposit as an unexplained inflow rather than a self-transfer with preserved cost basis.
