How this service works
Use when you need the current total supply of an ERC20 token on Base, Ethereum, Arbitrum, Optimism or Polygon, fetched live via totalSupply eth_call. Returns raw integer supply and a decimal-adjusted amount.
Output
Returns the raw integer total supply (as reported by the contract's totalSupply() function) and a decimal-adjusted floating-point amount accounting for the token's decimals, along with the queried contract address and chain.
Example use cases
Monitor token inflation on Base
“Check the current total supply of the token at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base and tell me the decimal-adjusted amount so I can track how many tokens are in circulation.”
Compare token supply across chains
“What is the total supply of the USDC contract 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8 on Arbitrum right now? Give me the raw integer and the human-readable supply.”
DeFi protocol token supply audit
“Pull the live total supply for the token at contract 0x4200000000000000000000000000000000000042 on Optimism — I need both the raw and decimal values to audit the protocol's tokenomics.”
Technical details
Endpoint
GEThttps://biosfera.46-62-215-147.sslip.io/o/erc20-supply?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a live, real-time totalSupply reading directly from the ERC20 contract on Base, Ethereum, Arbitrum, Optimism, or Polygon. Prefer it over indexers or off-chain data sources when accuracy and freshness matter, such as for DeFi analytics, tokenomics auditing, or cross-chain supply comparisons.
Side effects
- Invalid or non-ERC20 contract address returns an error or zero supply
- Unsupported chain value outside the allowed enum returns a validation error
- Contract address that is not a token contract may return unexpected results
- RPC node downtime may cause temporary fetch failures
- Malformed address (not matching 0x + 40 hex chars) returns a schema validation error
