What token is this? Read a Base token's name, symbol, decimals and total supply in one cheap typed call, with block-level freshness and explicit limitations. Identity is shared across agents for 7 days while total supply is re-read on every call beyond the block window the answer was quoted for. Positive-sum by design: $0.03 cold, $0.02 when the token identity is already shared, $0.01 on a shared full answer — and the wallet that seeded it earns a share of every reuse.

Is this transaction safe to sign? Simulate an unsigned Base transaction against current chain state and get one verdict back: what the call does, the gas it burns, which balances and allowances move, and whether it hides an unlimited approval or a target that changed under you. Returns allow, review or block with reason codes, evidence and the block it stops being valid. Never cached, shared or resold: your unsigned transaction stays private to the wallet that paid for it.
