Resolve any EVM contract ABI (even unverified, via decompilation), read, simulate, prepare txs.
Decode what a transaction did: decoded calldata (and trace when available), via heimdall.
Encode a function call to calldata (0x…) without sending anything.
Prepare a contract WRITE for the user to sign. Returns an UNSIGNED transaction, its simulation, a human-readable summary, an abi.ninja signing deeplink, and warnings. IMPORTANT: this tool NEVER signs or broadcasts. Present the summary + simulation + warnings to the user and hand them the `deeplink` — they sign in their own wallet. If `warnings` is non-empty (decompiled ABI, proxy, or a reverting simulation), surface it.
No maintainers met the attribution threshold for this repository.
Call a view/pure function and get the decoded result. No wallet, no cost. Rejects state-mutating functions.
