If you still hold KEEP or NU, you can still convert your tokens to **T.** The migration began around the launch of Threshold in 2022. That original migration experience is now legacy infrastructure, and the old upgrade UI is no longer a practical way to complete the conversion. *However, the underlying smart contracts did not disappear.* The KEEP and NU Vending Machine contracts were designed to remain available indefinitely, which means there is no migration deadline for liquid KEEP or NU tokens. If you still have KEEP or NU sitting in your wallet, you can interact with those contracts directly through **Etherscan.** It looks more technical than the old UI, but the process itself is relatively straightforward. {% hint style="danger" %} Before starting the swap, make sure your **KEEP or NU is in an Ethereum (ERC-20) wallet.** This wallet should have a **small amount of ETH for gas fees**, and make sure you are connected to the Ethereum Mainnet. {% endhint %} The conversion ratios were fixed when Threshold launched and are based on the respective token supplies rather than their market prices.

Open the KEEP/NU Token Addresses on etherscan, listed as: * KEEP : `0x85eee30c52b0b379b046fb0f85f4f3dc3009afec` * NU: `0x4fe83213d56308330ec302a8bd641f1d0113a4cc` a) Then connect the wallet containing your KEEP/NU. b) Find the function called: `approve` c) For `spender`, enter the KEEP/NU Vending Machine address d) For `amount,` enter how much KEEP/NU you want to convert. One slightly confusing part is that Etherscan expects the amount in the token’s smallest unit. KEEP/ NU has 18 decimals. *1 KEEP/NU* *`1000000000000000000`* *10 KEEP/NU* *`10000000000000000000`* *100 KEEP/NU* *`100000000000000000000`* {% endstep %} {% step %} ### Confirm the transaction in your wallet This transaction does not convert your KEEP/NU yet. It simply gives the Vending Machine permission to use the specified amount. {% endstep %} {% step %} ### Convert your KEEP/ NU to T Once your approval has been confirmed\ a) Open the [KEEP](https://etherscan.io/address/0xE47c80e8c23f6B4A1aE41c34837a0599D5D16bb0#writeContract)/ [NU](https://etherscan.io/address/0x1cca7e410ee41739792ea0a24e00349dd247680e#writeContract) Vending Machines: b) Select: *Contract → Write Contract → Connect to Web3* c) Connect the same wallet and find: `wrap` Under `amount` Enter the amount of KEEP/NU you want to convert, again using 18 decimals. *For example, for 100 KEEP/NU:* `100000000000000000000` {% endstep %} {% step %} ### Click `Write` and confirm the transaction in your wallet. Once the transaction is confirmed, the KEEP/NU will have been converted, and the corresponding T will appear in your wallet. {% endstep %} {% endstepper %} ## A few things to remember There is no deadline to upgrade liquid KEEP or NU into T. The Vending Machine contracts were intentionally designed to remain available to legacy token holders indefinitely. Remember that this requires two transactions: **Approve → Wrap → Receive T** You will therefore need enough ETH to cover gas for both transactions. Most importantly, do not simply send KEEP or NU to the Vending Machine contract address. Use the `approve` and `wrap` functions described above. If you are upgrading a significant amount and have never interacted directly with a smart contract through Etherscan before, consider converting a small amount first. Once you have confirmed that the T arrived correctly, you can repeat the process for the remaining balance. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.threshold.network/t-token/converting-nu-and-keep-to-t.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. 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.
