Crypto accounting on BOB

A practical overview to help finance teams on BOB.

BOB (Build on Bitcoin) is a hybrid Layer 2 that combines Bitcoin's security with Ethereum's programmability and DeFi ecosystem. It enables Bitcoin holders to use their BTC in DeFi applications without wrapping or bridging to other networks. BOB supports both Bitcoin scripts and Ethereum Virtual Machine, allowing developers to build applications that leverage both ecosystems. The platform aims to unlock Bitcoin's trillion-dollar market cap for decentralized finance applications.

  • Tracking historical token balances and cost basis for realized/unrealized gains.
  • Classifying DeFi (swaps, LP, staking, bridges) with clear audit trails.
  • Mapping activity to a chart of accounts for financial statements.

Common accounting treatments on BOB

  • Gas fees: typically expensed; capitalize when attributable to asset acquisition.
  • Swaps: disposal + acquisition with fair value at execution.
  • Staking rewards: recognize income upon receipt; track tax lots for disposals.
  • LP positions: record deposits/withdrawals; value positions to capture P/L.
