How this service works
Total and circulating supply for an ERC-20 on Base, read live from chain with decimals applied and the block height returned.
Output
Returns the total supply and circulating supply of the specified ERC-20 token on Base, with token decimals already applied so values are human-readable, along with the block number at which the data was read from the chain.
Example use cases
DeFi dashboard token supply display
“Pull the live total and circulating supply for the USDC token at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base — I need the decimal-adjusted numbers and the block height they were read at.”
Token launch supply verification
“We just deployed our ERC-20 at 0xAbCd1234AbCd1234AbCd1234AbCd1234AbCd1234 on Base. Can you confirm what total supply is showing on-chain right now, with decimals applied?”
Circulating supply monitoring for analytics
“Check the current circulating supply of the token at contract 0x4200000000000000000000000000000000000006 on Base and tell me which block height the data is from.”
Technical details
Endpoint
GEThttps://chainverdict.xyz/v1/data/supply/:addrWhen to prefer
Use this endpoint when you need live, decimal-adjusted ERC-20 token supply data specifically on the Base network with a specific block height reference for auditability. Prefer it over generic block explorer scraping for reliable structured output, or when building agents that need to verify token economics programmatically.
Side effects
- Invalid or non-ERC-20 contract address returns an error or zero values
- Contract address does not exist on Base (wrong chain or mistyped address)
- RPC node transient failure causing a read error
- Token with non-standard decimal implementation may return unexpected precision
