Please refer to the following FAQ to proceed with the migration and to discover the main Dex functionalities. This document is also available in French and in Spanish.
FAQ > TacoSwap DeX
- What exactly is Tacoswap?
Tacoswap is a decentralized finance app or DeFi. It is a decentralized exchange (DeX) on which you can swap one crypto with another. It also includes specific and standard features available in all DeXs such as adding and withdrawing liquidity into a pool and staking. Liquidity providers are rewarded by receiving eTACOs.
All transactions are executed through smart contracts which have been audited by Certik. (https://www.certik.org/projects/tacoswap)
2. Why should I migrate to the new platform?
Migration is necessary to use all DeX Taco features and earn eTACOs. The migration of liquidity was done automatically. Users must now migrate their TacoToken to eTACO.
3. What are the features of the DeX TacoSwap?
The new Tacoswap platform allows direct access to operations such as swapping without going through other platforms. You can create liquidity pools, add or withdraw liquidity, like all exchanges. Liquidity providers are rewarded and will receive eTACO.
4. Will the migration to the new platform have any impact on my assets?
Your level of invested liquidity remains the same. Only variations in market prices have an impact. Your number of eTACO will be the same as that of TacoToken.
5. What is eTaco?
eTACO is the native token of TacoSwap. It allows TacoSwap DeX to be identified and avoids confusion with other “taco”. It is the main reward for liquidity providers and the migration from TacoToken to eTACO is done on a 1:1 ratio (meaning for each TacoToken you have, you will receive one eTACO). The production of TacoToken is sent automatically in a closed contract. Pools in the old version of TacoSwap are therefore no longer remunerated. TacoSwap has now a deflationary strategy in place so that the DeX can live on and attract more users and traders. The production of eTACO is limited to 395M and started at 300M where the one from TacoToken stops. The eTACO production is decreasing and will stop on March 2023. Therefore there is 95M eTACO to be distributed to new liquidity providers on the DeX
The value of eTACO is visible on the DeX TacoSwap, by clicking on “Earn > eTACO price”. As soon as the eTACO is listed on platforms such as CoinMarketCap, Coingecko, etc. its price will also be visible on the Etherscan.
6. What will happen with the old version of TacoSwap?
The website remains available. But the pools are no longer remunerated.
7. What’s going to happen with TacoToken?
TacoToken issued after migration are automatically directed to a locked contract. Migration to eTACO is possible for several weeks. However, TacoToken holders are now advised to switch to eTACO.
8. Why is eTACO production limited?
The eTACO makes it possible to reward liquidity providers. It helps motivate traders to use our DeX to acquire eTACOs before the production stops. In addition, it is expected that production will gradually decrease until March 2023 when it will be stopped. Note that the production of eTACO starts at 300M since it is at this level that the production of TacoToken was sent on a closed contract. Therefore, there is only 95M to be distributed to new liquidity providers
9. How does migration work? What do I have to do?
“Note: existing liquidities on the pools have been migrated automatically. Each user is responsible for migrating his TacoToken to eTACO
1) Go to the old version of the site https://v1.tacoswap.io/
2) Go to each pool where you made a stacking
3) Click on “Claim”
4) Your TacoToken will appear on Metamask
5) Go to the TacoSwap DeX website https://www.tacoswap.io/swap
6) Click on connect your wallet
7) Follow the instructions of your wallet (accept communication between TacoSwap and your wallet)
8) Your eTACO will appear on your Metamask, equal to your contribution in terms of liquidity
10. I first clicked on “Unstake” in the old version of the site?
You received Dummy Tokens in your wallet. You need to keep them. As of today (July 7h), we know that roughly 60 people are impacted. This issue will be addressed at the soonest to help you recover your liquidity.
11. What is a Dummy Token?
By definition, when we unstake, the smart contract must send the user a token. However, as the pools on the old version of the site are no longer remunerated, no TacoToken can be sent.
You receive instead Dummy Tokens, they have no value. But keep them in your wallet.
12. How does the remuneration of liquidity providers work?
By adding liquidity to a pool, you automatically receive eTACO Liquidity Pool Tokens (TLP). By “staking” your TLPs, you will receive eTACOs. For information, the TLP is the TacoSwap version of SLP or Uni LP.
13. Can I create a new pool?
Yes, it is possible to create a new pool, but will not be renumbered in eTACO. However, if the pool grows and attracts a certain level of liquidity, renumeration into eTACO will be possible.
14. CRD?
The CRD holder contract has been migrated successfully. The CRD-ETH pools of UniSwap and SushiSwap have not yet been migrated. It is up to the CRD community to decide later on which exchange it wishes to have its pools on.
15. Swap functionality
Like on every DeX, you can swap between the available tokens that are listed and available in the DeX pool. This is why it’s important to launch the trading activity on the DeX, to create new pools and attract new liquidity providers by rewarding them with eTACO.
Our DeX could be interesting for smaller tokens with a project that will not be able to get visibility on bigger platforms.
Here is the tutorial on the Swap function:

16. Which pools are transferred to the DeX?
The transferred pools are:
ETH — Link
ETH — BePro
ETH — Rook
ETH — PoolZ
ETH — XED
ETH — Nexo
ETH — DAI
ETH — USDT
ETH — Sushi
CRD Holders
Regarding the CRD pools, please check the answer to question 14.
Regarding the ETH-Taco pool, please check the answer to question 20.
17. Which are the pools whose liquidity hasn’t been transferred yet?
The ETH-CRD pool (UniSwap)
The ETH-CRD pool (SushiSwap)
The ETH-TACO pool. Please note that this pool is currently inactive.
18. What about my SLP and my Uni LP?
For the transferred pools, the SLP or Uni LP are automatically transferred into TLP.
For the CRD and ETH-Taco pools, operations need to be done manually (cf. following questions).
19. Unstacking functionality is no longer available on TacoSwap’s previous version (v1)
That’s correct. This functionality is no longer available on the v1 site since all liquidities have been migrated to the new version, except for the CRD-ETH pools and ETH-TACO pool.
In all pools (including CRD holder), unstacking is directly available on the new site version. This will allow you to withdraw your liquidity.
20. How to remove liquidity in the ETH-TACO pool and transfer it to the ETH — eTACO pool?
On the TacoSwap DeX, go to the ETH-TACO pool (https://www.tacoswap.io/farms/TACO-ETH%20TLP):
1) Unstake (this will automatically trigger the “claim” of your TACO)
2) You will then receive your UniV2 LPs in your wallet
3) Go to UniSwap, click on “Remove”
4) You will then receive your ETH and TacoTokens in your wallet
5) You now have two options:
Option a)
Add an account to your Metamask
Transfer your TacoToken
Execute the migration from step 5 (cf. question 9)
Add liquidity to the ETH — eTACO pool:
https://drive.google.com/file/d/1g7ZQvkqxhV-FrUytBdv2Mz7GffTw8Iu7/view?usp=sharing
You will receive TLPs. Then you can stake them (cf. question 24 “how to stake?”)
Option b)
Wait until the direct swap link between Taco and eTACO is available
21. How to remove liquidity from CRD pools?
To remove liquidity from ETH-CRD pools:
1) Unstake (this will automatically trigger the “claim” of your TacoTokens)
2) You will then receive your SLPs or UniV2 LPs in your wallet as well as your TacoTokens
3) Go to Sushiswap or UniSwap websites and click on “remove liquidity” in the ETH — CRD pool
4) You will then receive your ETH & CRD in your wallet
22. How to unstake in the CRD holder pool?
On TacoSwap DeX, go to CRD Holders, click on unstake. You will receive your CRDs in your wallet.
23. How to add liquidity?
On the TacoSwap DeX, click on” “Earn”, then on the “Pools” tab
In the link below you will find an example with ETH-LINK.
If you do not have LINK or ETH in your wallet, you will see the message “funds insufficient”. You must first swap what you need in the “swap” menu.
The second step is to add liquidity, approve and validate the transaction.

27. Why is the value of eTACO so much lower than TacoToken?
In a DeFI project, the Tech team has no influence on the Token’s price. As of today (07/07/21), we notice that in the eTACO-ETH pool on the TacoSwap DeX there is only 2.54 ETH. The pool doesn’t have enough liquidity for the price to be significant. The eTACO’s price will go up according to liquidity supply, purchases and sales. It is the law of the market. Currently, the APY is over 175%.
28. If I don’t migrate right away, am I screwed?
Migration is available indefinitely. Each user is responsible for the migration of his own TacoTokens to eTACO. This functionality will remain available for some time but it’s in the users’ interest to go through the migration at the soonest to be able to use the DeX, provide liquidity and earn eTACO.
Any new liquidity supply in the TacoSwap DeX will generate TLPs (TacoLP Token — the equivalent of SLP or UniV2 LP). By stacking them in the “farm” tab, you will get eTACOs.
29. If I farm TacoTokens on the Dex, will it automatically generate eTACO?
NO. Absolutely not. Your TacoTokens will be lost by sending them in the farming contract on the DeX.
For the moment, the only solution is to transfer your TacoTokens to eTACO, so follow the steps of the migration explained in question 9.
30. What is the governance module?
The governance module allows the Tacoswap DeX community to decide on the future of the Dex and propose features, functionalities or anything related to the Dex. This is done by a voting system according to the number of eTACOs owned.
There are two main options available:
1) You can see active proposals made by other members of the Tacoswap community on https://vote.tacoswap.io/#/, then decide to vote for it or not
2) You can create your own proposal using this link: https://vote.tacoswap.io/#/tacoswap.eth/create where Tacoswap users can vote for it.
31. Why some pools are in grey?
For the moment, the pools colored in grey are unavailable for trading/stacking directly via Tacoswap as these functionalities are being created! The only way to stack/trade in these pools is to go through Sushiswap/UniSwap. We will be detailing more on how to invest in these pools soon!
32. Why keep Tacoswap v1 online if everything has been moved to v2?
V1 is still needed to claim TACO for those who didn’t migrate or migrated without claiming.
It’s important to understand that the liquidity from the pools has been migrated (apart from the 2 CRD pools and the ETH-TACO). But the user’s share of the pool represented by his/her number of TACO hasn’t been transferred. This operation has to be done manually following the steps in the order listed on answer 9.
33. I already migrated but I found out I still have TACO. Can I swap them with eTACOS?
Yes, that’s totally possible. If you already migrated and found out you still have some TacoTokens in your Metamask, you can go to “migrate” on the new DeX. Click on ‘’Swap’ and “Confirm” and the remaining TacoTokens will be swapped with eTACOS.
Please note that if you have some unclaimed TacoTokens in the v1 of the DeX, you need to claim them first, and make sure all your TacoTokens are on your Metamask Wallet.

34. My transaction failed but I still had fees charged. Why? Can I get a refund?
A transaction may fail for different reasons. For example, if you do a swap operation while setting gas fees to ‘low’, the transaction may fail and the gas fees will still be charged. But in general, Metamask will prevent you from doing an operation that could fail. This is how the Mainnet network works and we have no control over it. Unfortunately, we cannot refund you in that case.
