In DeFi, monetary value rarely remains on a single blockchain; therefore, businesses frequently transfer assets between blockchain networks to optimize costs, gain access to liquidity, and participate in diverse protocols. This cross-chain activity, aided by bridge transactions and wrapped assets, now drives billions of dollars in daily volumes.
Wormhole, LayerZero, and Hop are examples of bridge protocols that facilitate such transfers by locking up the original assets on one chain (the source) and issuing wrapped tokens on the other chain (the target). While this opens up powerful DeFi strategies, it poses accounting challenges that traditional finance systems were never designed to handle.
Some of the key challenges include preventing double-counting assets, determining when bridging triggers taxable events, and maintaining audit trails across various networks. This guide provides practical guidance on accounting for wrapped crypto assets while ensuring compliance with IFRS and US GAAP.
What Are Bridge Transactions in Crypto
Bridge transactions enable asset transfers between different blockchain networks through smart contract protocols. These systems lock assets on the source chain and mint equivalent tokens on the destination chain.
Common Bridge Types
Native Bridges: Blockchain teams build these for their specific ecosystems. Examples include Polygon PoS Bridge for Ethereum-Polygon transfers and Arbitrum One Bridge for Ethereum-Arbitrum movements.
Third-Party Bridges: Independent protocols support multiple chains. Wormhole connects 20+ networks, including Ethereum, Solana, and Terra. Similarly, LayerZero enables omnichain applications with unified liquidity.
DEX-Integrated Bridges: Protocols like Hop and Synapse combine bridging with automated market makers, allowing for seamless integration. This enables direct swaps across chains.
Bridge Mechanics
The process works systematically: users deposit assets into smart contracts on the source chain. Subsequently, the protocol verifies the deposit and mints equivalent tokens on the destination chain. Meanwhile, original assets remain locked until users initiate the reverse bridging process.
Organizations bridge assets to access lower fees (Ethereum to Polygon), faster settlement (Ethereum to Arbitrum), or specific DeFi protocols unavailable on their primary chain. Furthermore, treasury operations might bridge stablecoins to optimize yield farming across multiple networks. This approach requires sophisticated crypto accounting methods to track accurately, since a manual approach is error-prone and time-consuming. However, a platform like Koinx Books can help automate the process.
Understanding Wrapped Assets: WBTC, wETH, and More
Wrapped assets represent tokenized versions of cryptocurrencies on non-native blockchain networks. They typically maintain 1:1 backing through various mechanisms.
Wrapped Bitcoin (WBTC): This ERC-20 token on Ethereum maintains backing by Bitcoin held in custody. With a market cap exceeding $15 billion, it ranks among the largest wrapped assets.
Wrapped Ether (wETH): This ERC-20 version of ETH enables standardized token interactions within smart contracts. Many DeFi protocols require wETH since they can’t handle native ETH directly.
Bridged Stablecoins: These include USDC on Polygon, USDT on BSC, and similar tokens created through official bridge protocols.
Synthetic Assets: These tokens represent exposure to underlying assets without direct backing. Examples include synthetic stocks, commodities, or forex pairs on platforms like Synthetix.
Each wrapped asset has unique smart contract addresses, requiring separate tracking in accounting systems. Despite 1:1 pegging mechanisms, wrapped tokens may trade at slight premiums or discounts due to liquidity differences or bridge risks. Therefore, they introduce a set of accounting complexities that go far beyond tracking regular crypto holdings.
Key Accounting Challenges with Bridge and Wrapped Assets
As previously stated, bridge transactions and wrapped assets create several accounting complexities that finance teams must address systematically. These include:
1. Double-Counting Risk
The primary challenge involves preventing duplicate asset recognition. When bridging ETH to Polygon, the original ETH becomes locked, while the bridged ETH appears on Polygon. Consequently, accounting systems must recognize only the accessible wrapped asset, not both versions.
2. Asset Classification Complexity
Wrapped tokens differ technically from their underlying counterparts. This requires separate chart of accounts entries. For instance, WBTC is an ERC-20 token, not Bitcoin, despite economic equivalence.
3. Valuation Discrepancies
Wrapped assets may trade at slight variances from underlying assets. This occurs due to bridge risks, liquidity differences, or market inefficiencies. These discrepancies require careful fair value assessment.
4. Bridge Risk Assessment
Bridge protocols face vulnerabilities in smart contracts, validator attacks, and liquidity crises. The Wormhole exploit resulted in $320 million in losses, highlighting risks that may affect asset valuations. Effective crypto asset management strategies must account for these risks.
5. Cross-Chain Reconciliation
Organizations operating across multiple chains must regularly reconcile their positions. This ensures wrapped asset balances align with underlying asset locks and business intentions.
6. Audit Trail Complexity
Bridge transactions involve multiple blockchain networks with different transaction formats. This makes maintaining comprehensive audit trails challenging without specialized tools.
How to Record Bridge Transactions in Crypto Accounting
Recording bridge transactions requires a systematic approach that maintains accuracy while preventing double-counting. This process represents core crypto accounting for the bridges methodology.
Step-by-Step Bridge Recording Process
Step 1: Pre-Bridge Documentation First, document business purpose, source/destination chains, expected amounts, and authorized personnel.
Step 2: Record Source Chain Transactions. When initiating bridge transactions, record the asset lock rather than disposal:
Example: Bridging 100 ETH from Ethereum to Arbitrum
DR Bridge Pending – ETH | $250,000 (100 ETH × $2,500 |
CR ETH Asset – Ethereum | $250,000 |
Step 3: Destination Chain Asset Recognition Upon receiving wrapped assets:
DR ETH Asset – Arbitrum | $250,000 |
CR Bridge Pending – ETH | $250,000 |
Step 4: Fee Recognition Bridge fees require separate expense recognition:
DR Bridge Fees Expense | $50 |
CR ETH Asset – Ethereum | $50 |
Most jurisdictions don’t consider bridging a taxable disposal since economic ownership remains unchanged. However, fees represent deductible expenses. For comprehensive guidance, consult crypto tax software designed for complex DeFi operations.
Accounting Treatment for Wrapped Assets (IFRS vs. GAAP)
International accounting standards offer various frameworks for treating wrapped assets, which impact recognition and measurement requirements.
IFRS Treatment
Under IFRS, wrapped assets typically qualify as intangible assets requiring separate recognition. Key considerations include initial recognition at cost, subsequent measurement using either the cost or revaluation model, and impairment when the carrying amount exceeds the recoverable amount.
US GAAP Treatment
US GAAP requires more restrictive treatment: historical cost recording without upward revaluation, impairment-only adjustments, and annual testing requirements.
Aspect | IFRS | US GAAP |
Initial Recognition | Cost + transaction costs | Cost + transaction costs |
Upward Revaluation | Permitted with the revaluation model | Prohibited |
Impairment Frequency | When indicators exist | Annually + indicators |
This represents crucial IFRS and GAAP considerations for treating crypto assets in finance teams.
