mine_blockMines exactly one new block on a Virtual TestNet. Required after increase_time to make time changes take effect. Do not call in a loop to advance many blocks — instead, use increase_time to jump forward by the desired duration, then call mine_block once. Requires an active project and vnet (set via set_active_project and set_active_vnet).
resimulate_transactionReplays an on-chain transaction in Tenderly's simulation environment to get a full decoded execution trace. Useful for debugging reverted or suspicious transactions. Requires an active project (set via set_active_project).
resimulate_vnet_transactionRe-traces a previously executed Virtual TestNet transaction by its operation ID (from get_vnet_transactions). Returns a summary with status, gas usage, and decoded method. Use follow-up tools (listed in the response hint) to inspect state changes and generated access lists. Requires an active project and vnet (set via set_active_project and set_active_vnet).
revert_vnetReverts a Virtual TestNet to a previously created snapshot, undoing all state changes since that point. The snapshot is consumed — create a new one with snapshot_vnet if you need to revert again. Typical pattern: snapshot_vnet → run scenario A → revert_vnet → run scenario B → compare. Requires an active project and vnet (set via set_active_project and set_active_vnet).
send_vnet_transactionSends and executes a transaction on a Virtual TestNet. The sender is impersonated — no private key needed. Omit 'to' for contract deployment. Requires an active project and vnet (set via set_active_project and set_active_vnet).
set_active_projectSets the active Tenderly project for subsequent tool calls. Must be called before tools that require a project context.
set_active_vnetSets the active Virtual TestNet for subsequent tool calls. All VNet tools operate on the active VNet — call this before using them. Use list_vnets to find available VNets. Automatically called when you create or fork a VNet. Requires an active project (set via set_active_project).
set_erc20_balanceSets the ERC-20 token balance of any address on a Virtual TestNet. Use this to give test accounts specific token balances without transfers or approvals. For native token (ETH/MATIC) balance, use fund_account instead. Requires an active project and vnet (set via set_active_project and set_active_vnet).
set_storage_atSets a raw storage slot value at any contract address on a Virtual TestNet. This is a low-level primitive — prefer set_erc20_balance for token balances and fund_account for native balance. Use this only when you need to write a specific storage slot directly (e.g. Chainlink oracle price override, protocol parameter bitmap, liquidity index). Requires an active project and vnet (set via set_active_project and set_active_vnet).
simulate_transactionSimulates a transaction on any Tenderly-supported EVM network without spending gas. Returns the outcome including decoded traces, gas usage, and revert reason. For reverted transactions, includes decoded custom Solidity errors with name and typed parameters when available. Requires an active project (set via set_active_project).
simulate_vnet_transactionSimulates a transaction on a Virtual TestNet without changing its state. Returns a summary with status, gas usage, decoded method, and decoded error details for reverted transactions. Omit 'to' for contract deployment. Use follow-up tools (listed in the response hint) to inspect call traces, events, and gas breakdown. Requires an active project and vnet (set via set_active_project and set_active_vnet).
snapshot_vnetCreates a state snapshot of a Virtual TestNet and returns a snapshot ID. Use before running a simulation scenario so you can revert back with revert_vnet. Snapshots are lightweight — take one before any destructive or exploratory operation. Requires an active project and vnet (set via set_active_project and set_active_vnet).
trace_transactionTraces an on-chain transaction's execution and returns a summary: status, gas used, decoded method name, and error details. For reverted transactions, includes decoded custom Solidity errors with name and typed parameters when available. Use follow-up tools (listed in the response hint) to inspect call traces, events, and state changes. Requires an active project (set via set_active_project).
trace_vnet_transactionReturns a decoded execution trace summary for a Virtual TestNet transaction — contract name, function name, decoded input parameters, decoded output, and decoded error details for reverted transactions. For deeper analysis, use follow-up tools listed in the response hint. Pass the operation_id from get_vnet_transactions. Requires an active project and vnet (set via set_active_project and set_active_vnet).
vnet_callExecutes a read-only eth_call on a Virtual TestNet without changing state. The data field must be ABI-encoded calldata (4-byte function selector + encoded arguments). Returns raw hex — decode with the contract ABI to extract return values. For reading multiple addresses at once, prefer vnet_multicall to save round trips. Result is truncated to 10 KB if the return data is very large. Requires an active project and vnet (set via set_active_project and set_active_vnet).
vnet_multicallExecutes up to 10 read-only eth_call requests in a single batch on a Virtual TestNet. Returns one result per call, in the same order. Each call's data must be ABI-encoded calldata (4-byte function selector + encoded arguments). Prefer this over multiple vnet_call invocations when reading data for several addresses or contracts. Individual results are truncated to 10 KB if very large. Requires an active project and vnet (set via set_active_project and set_active_vnet).
