evm-token-decimals

EVM token balances drift across chains due to silent decimal mismatches when tooling assumes default decimals instead of querying the actual token contract. Normalizing all amounts to 18 decimals ensures consistent cross-chain accounting and pricing.

You normalize EVM token balances by performing runtime decimals() lookups on the token contract, then converting the raw amounts to a standard 18 decimals. This creates consistent cross-chain comparisons for DeFi analytics and portfolio tracking.

You reduce RPC load by implementing chain-aware caching keyed by chain_id and token_address. This stores fetched token decimals locally, eliminating redundant RPC calls and significantly speeding up repeated web3 lookups.

Yes, this approach includes defensive handling specifically designed for tokens with non-standard decimals and bridge scenarios. It reliably reads and caches the correct decimals across multi-chain ecosystems to prevent calculation errors.

Yes, this decimal normalization is suitable for bots, dashboards, and portfolio trackers operating across multi-chain ecosystems. It ensures reliable balance reporting and pricing by resolving silent decimal mismatches across EVM chains.

The best way to standardize token decimals across multiple EVM chains is to fetch them on demand via runtime lookups and normalize all amounts to 18 decimals. Caching these values by chain_id and token_address optimizes performance.
