6 | | -# Faucets (Limits) |
7 | | - |
8 | | -Starknet currently has a number of limits in place in order to keep the network stable and optimized for the best performance. |
9 | | - |
10 | | -Blockifier-related constants and limits are defined, for each Starknet version starting from v0.13.0, in a JSON file called ``` |
11 | | -versioned_constants``` in this [directory](https://github.com/starkware-libs/sequencer/tree/main/crates/blockifier/resources) |

13 | | -## Starknet’s current limits |
14 | | - |
15 | | -| Entity | Description | Sepolia | Mainnet | |
16 | | -| --------------------------------- | --------- | ------------- | ----------------------------------------------------------------------------------------------------------------------------- | |
17 | | -| **Block time** | The maximum amount of time within which a pending block is closed, if no other limit is met | `30 seconds` | `30 seconds` | |
18 | | -| **Block limit (Cairo steps)** | The maximum number of Cairo steps that can be completed within each block to ensure block production times remain consistent and predictable | `40,000,000` | `40,000,000` | |
19 | | -| **Block limit (gas)** | Certain Starknet operations, such as sending messages between L1 and L2, consume Ethereum gas. The current L1 state update mechanism involves an Ethereum transaction for each Starknet block.| `5,000,000` | `5,000,000` | |
20 | | -| **Max transaction size (Cairo steps)**| The maximum number of computational steps, measured in Cairo steps, that a transaction can contain when processed on the Starknet network. This limit is important for ensuring the efficient execution of transactions and preventing potential congestion. | `10,000,000` | `10,000,000` | |
21 | | -| **Max number of events per transaction** | The maximum number of events that a transaction can emit during its execution. | `1000` | `1000` | |
22 | | -| **Max number of data felts per event** | The maximum number of felts that an event can contain in its `data` array. | `300` | `300` | |
23 | | -| **Max number of key felts per event** | The maximum number of felts that an event can contain in its `keys` array. | `50` | `50` | |
24 | | -| **Max Cairo steps for `validate`** | The maximum number of computational steps, measured in Cairo steps, for a `validate` function. | `1,000,000` | `1,000,000` | |
25 | | -| **Max contract bytecode size (Number of felts in the program)** | The maximum size of the bytecode or program that a smart contract can have on Starknet.Bytecode is the low-level code that comprises smart contracts. Limiting this size helps manage the complexity of contracts and the overall efficiency of the network | `81,290` | `81,290` | |
26 | | -| **Max contract class size** | The maximum size for a contract class within Starknet.Contract classes are a fundamental building block for smart contracts, and limiting their size can have implications for the network’s scalability and security. | `4,089,446 bytes` | `4,089,446 bytes` | |
27 | | -| **IP address limits (read/write)** | In order to reduce network spam, Starknet limits the amount of contract reads and writes that a single IP address can make. | `200 per min per IP address` | `200 per min per IP address` | |
28 | | -| **Signature length (felts)** | | `4,000` | `4,000` | |
29 | | -| **Calldata length (felts)** | | `4,000` | `4,000` | |
