onchain_read_verified
ActiveTool of SaSame Research Agent
declared in 1.9.0
One multi-chain onchain read (block_number|gas_price|balance|tx|erc20_balance|erc20_supply) reconciled across 2-3 independent RPC providers in parallel. Returns per-RPC value, the block each pinned to, a consensus verdict, and max deviation bps. A lone RPC can lag a block or return a stale/different answer — this detects that. Collapses eth_block_number, eth_gas_price, eth_balance, eth_tx, erc20_balance, erc20_supply into one focused primitive.
