The following table presents limits of setup and execution of [Web3 Actions](/monitoring/web3-actions/introduction): | What | Limit | Customizable?\* | | - | - | - | | Execution duration\*\* | 30s timeout | Yes | | Total number of Web3 Actions | [Contact sales](https://tenderly.co/contact-us) to discuss capacity | Yes | | Memory allocation (RAM) | 128 MB | Yes | | Sequential actions rate limit\*\*\* | 400 executions/5 min | Yes | | Parallel actions rate limit\*\*\* | 2000 executions/5 min | Yes | | Package size | 40MB zipped (including `node_modules`) | No | | Webhook trigger payload size | 5 MB | No | | Action source size (dashboard editor) | 5 MB | No | \*Customizable restriction per quote. \*\*Executions longer than defined timeout will be terminated. \*\*\*Rate limits apply per action: each action has its own execution budget. Any additional executions are skipped and appear as `RATE_LIMITED` in the [execution history](/monitoring/web3-actions/references/execution#web3-action-execution-status-types). Email notifications about skipped executions are batched: you receive at most one email per action per 24 hours. See [Notifications](/monitoring/web3-actions/references/notifications) for how to configure these email delivery channels. When your account's usage quota is exhausted, further executions end with the [`TU_QUOTA_REACHED`](/monitoring/web3-actions/references/execution#web3-action-execution-status-types) status. They are dropped without retry and no email is sent. [Contact our support team](https://tenderly.co/contact-us) for custom limits.
