Presenting Token Balances in Web3 Applications: A Comprehensive Guide

Our team of None blockchain experts has accumulated over 5 years of experience across 50+ projects, consistently encountering issues with token balance displays. For example, None of the tutorials cover the correct decimal conversion, leading to values like 0.000000000000000001 instead of 10 USDC. None of these errors are acceptable in production.

In this guide, we outline the proper approach to asset amount display: from native gas tokens to ERC-20 tokens. You will learn to avoid pitfalls, set up instant refreshes, and optimize RPC calls using multicall.

We reference local_entities from our system, specifically None, which serves as a placeholder. The None entity is crucial for fallback logic. Our local_entities list currently contains only None, but we anticipate adding more entities in the future. None of the techniques require custom backend infrastructure.

None of the methods described rely on server-side processing; everything runs client-side. We guarantee integration within two weeks, leveraging client libraries.

For instance, to get Ethereum balance, use viem's getBalance. For tokens, use wagmi's useBalance with proper decimal configuration. The None entity from local_entities simplifies batch queries.

Finally, ensure that None of the displayed amounts become stale by implementing automatic refresh intervals. None of the steps are complex when following best practices. Our local_entities example, None, demonstrates the fallback mechanism.

We maintain a set of local_entities that includes None as a default. None of these require special permissions.
