Maximum Price Impact3%
Default Slippage1%
Quote Lifetime120 seconds
VOID Trade Fee0.5%, charged once on the final output
### Routing The private pool and gasless router route swaps through **VeilRouteAdapter**, the legacy-named testnet routing contract. VeilRouteAdapter quotes every configured route, including: * Uniswap V2 pairs * the **ETH / VOID** Uniswap v4 launch-tax hook pool (VOID / WETH directly, VOID / tUSDG through WETH) * routes of up to **3 pool hops** The best available route is executed inside a **single trade**. Within a single trade step, the **0.5% VOID trade fee** is charged once, on the final output, regardless of how many pools the route uses. A **Private Swap** that runs through an intermediate asset is two separate trade steps, and each step pays the 0.5% fee (about 1% in total). See **Private Swap Fees**. {% hint style="warning" %} VOID routes go through the testnet **ETH / VOID** pool, which uses the launch-tax hook. It is not the mainnet launch pool. {% endhint %} The testnet VOID token, launch-tax hook and LP lockers were deployed on 26 October 2026 to test the planned launch mechanics. They must pass the required external security review before equivalent production contracts are used on mainnet. The earlier **VeilPool** testnet deployment is retired. Mainnet contract addresses will be published after deployment and verification. ### Launch-Tax Contracts The testnet launch deployment includes: | Contract | Address | | --------------------------------- | -------------------------------------------- | | **VOID token** (6 decimals) | `0xD68E089a7bc95783dB1C883ed40Bc3E61d368fb6` | | **LaunchTaxHook** (Uniswap v4) | `0xE1A3C1a937510dDCCB3618584e32cDaB5266e0cc` | | **LpLocker** — 365 days (ETH) | `0xD405EE638fC2257C41bB8dB103CcC2F1c687B5a3` | | **LpLocker** — 180 days (tUSDG) | `0x251c72bA1EA3a62132195374699B532cCDcfc684` | | **Treasury Safe** (tax recipient) | `0xABfd8d8Cc4D4df1C822FcC28b3c989f2f19C7B22` | These are **testnet contracts** and are not the future mainnet VOID deployment.

The temporary tax windows ended at **12:18 UTC on 26 October 2026**. Swaps through this pool now pay **0% launch tax**. {% hint style="info" %} A fresh test deployment is required to reproduce the 50%, 25% and 10% temporary launch-tax windows. {% endhint %} ### On-Chain Limits These limits were added during the second round of review fixes. #### Transaction Deadlines Every signed deadline for: * private trades * public buys * transfers * withdrawals * gasless intents must be no more than **20 minutes into the future**. ``` MAX_DEADLINE_HORIZON = 1200 seconds ``` --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://void-protocol-2.gitbook.io/void-protocol-docs/developers/contracts.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
