FAQPage Schema

How do I handle EVM token decimal mismatches across multiple chains?▼

To handle EVM token decimal mismatches across chains, you query token decimals on-chain at runtime and cache the results by chain and token address. This standardizes internal accounting and prevents silent calculation errors in DeFi tools.

Why does my DeFi bot show incorrect token balances for bridged assets?▼

Your DeFi bot shows incorrect token balances for bridged assets due to silent decimal drift. Safely normalizing bridged tokens with runtime decimal lookups ensures precise balance calculations and prevents these discrepancies across EVM chains.

Can I use web3.py to query token decimals on Ethereum for a specific wallet?▼

Yes, you can use web3.py to query token decimals on Ethereum. The skill fetches the decimals for a specific token address and wallet, enabling chain-aware caching and safe normalization for accurate on-chain interactions.

What is the best way to standardize token balance precision for DeFi dashboards?▼

The best way to standardize token balance precision for DeFi dashboards is to perform runtime decimal lookups and apply chain-aware caching. This safely normalizes internal accounting, ensuring accurate comparisons and pricing across different EVM networks.

Do I need web3.py installed to fetch EVM token decimals at runtime?▼

Yes, you need web3.py installed to fetch EVM token decimals at runtime. The skill requires web3.py for Ethereum contract interactions to identify and mitigate decimal mismatches in token balances across EVM chains.
