Pre-flight check on a Base mainnet address before paying it. Returns contract-vs-EOA, ETH and USDC balances, outbound transaction count, and warnings about whether funds sent there can actually be mov…
ERC-20 allowance on Base: how much a spender may pull from an owner, whether it is an unlimited approval, the owner balance, and how much is actually spendable right now. Defaults to USDC. Query param…
What an UNVERIFIED Base contract can actually do, which is exactly where block explorers show nothing. Disassembles the deployed bytecode with a PUSH-aware opcode walk, strips the Solidity metadata tr…
Identify what a Base contract actually is: ERC-20, ERC-721 or ERC-1155 via ERC-165, plus proxy detection across EIP-1967, EIP-1822 and the legacy ZeppelinOS slot, with the current implementation addre…
Live Base mainnet gas oracle: current gas price, base fee, recent base fee trend, priority fee percentiles, and the estimated cost of a plain ERC-20 transfer in ETH. No parameters.
ETH and USDC balances for up to 20 Base addresses in a single call, with per-address funded flags and totals. One request instead of forty RPC round trips. Query param: addresses (comma-separated).
ETH/USD and BTC/USD read live from Chainlink on-chain price feeds on Base, including the feed description, decimals, update timestamp, age in seconds and a staleness flag. Oracle data from the chain i…
Will this token payment actually go through, and if not exactly why. Simulates the transfer without spending gas, decodes the real revert reason (Error(string), Solidity Panic codes translated to Engl…
ERC-20 token metadata on Base mainnet: name, symbol, decimals and total supply, read straight from the contract. Query param: address.
USD price for ANY token on Base, not just the two assets Chainlink covers. Discovers every Uniswap V3 pool against WETH and USDC across all four fee tiers, reads sqrtPriceX96 and does the Q96 fixed-po…
Confirm a Base mainnet transaction: success or reverted, block, confirmations and finality, gas used, and every ERC-20 transfer it moved with USDC amounts decoded. Verify a payment actually landed. Qu…
