Merlin is an auto-compounding yield aggregator with an ecosystem optimized to focus on safe and sustainable maximum yield return.


Cryptocurrencies have been a prominent topic in the financial market for many years now. Since its inception, cryptocurrencies have created strong developments that also become a part of everyday life. Even though there aren’t too many people using cryptocurrencies today, there are a number of large establishments accepting cryptocurrencies for payments.Currently, Defi has also created a great attraction for this market, and on the basis of building projects on Defi. And to be able to connect innovators with investors, through decentralized swaps and an interactive user interface to easily manage pre-listing liquid auctions.

Merlin is an auto-compounding yield aggregator with an ecosystem optimized to focus on safe and sustainable maximum yield return. Merlin takes care of gas costs, APY tracking, optimal yield strategies, security with the goal of maximizing DeFi users’ yield farming at the lowest possible cost (All APY & APRs displayed are inclusive of fees).

The rise of decentralized finance (DeFi) has been an incredible boon for the entire cryptocurrency sector. Despite the surge in DeFi products on Binance Smart Chain (BSC), there are no functional farming projects that truly facilitate users holistically. Merlin combines yield maximization with functionality, delivering an all-encompassing DeFi platform. Merlin recognize the exponential benefit in auto-compounding and the value in accumulating key cryptocurrencies (aka. BTCB, ETH, BNB, CAKE, etc.), so we’ve built:
A yield aggregator that helps you auto-compound your assets
An ecosystem that helps you earn more key cryptocurrencies (aka. BTCB, ETH, BNB, CAKE, etc.) by staking $MERL

The development of decentralized finance (DeFi) has increased significantly in the cryptocurrency sector. Despite the explosion of DeFi products on Binance Smart Chain (BSC), none of the farming projects really support users. Merl token combines the functions of rate optimization, conveying the full functionality of a DeFi platform.

  • A profit aggregator that helps you combine your assets automatically .
  • An ecosystem that helps you optimize your profit margin (like BTCB, ETH, BNB, CAKE, etc.) by Staking MERL tokens.
  1. Merlin Magical Lottery:

This is one of many deflationary mechanisms Merlin will be launching in the coming months. Their Merlin Magical Lottery gives everyone a chance to win the lottery every single day!

How does it work? ‌

Lottery Ticket Fee for 1 ticket: 0.2 Merlin (This may be adjusted over time depending on Merlin price). Single User Lottery Entry Limit: No overall limit, but only 50 can be bought each time. Paying for one ticket will give users a random 4 digit combination with each digit being between 1–14, e.g. 3–6–3–9”

How to win

To win the lottery jackpot (50% of the entire lottery pool), users need to match all 4 numbers on their ticket in the exact same order as the 4 winning numbers.‌ There are many chances to win! As long as you match 2 or more numbers in the correct order, you are guaranteed to win a prize.‌

Winning Ratio‌

Match all 4 numbers in the exact order = win 50% of the pot (or split the pot if more than 1 winner). Match 3 numbers in the exact order = win or split 20% of the pot. Match 2 numbers in the exact order = win or split 10% of the pot. Burn the remaining 20% of the pot. Please note — in the event that no participants were able to match 3 numbers on any draw, the 20% allocated to winners will then be burned accordingly. ‌For example, if the final 4 winning numbers are “1–9–3–2

‌“2–3–9–1” = match 0

“1–9–3–2” = match all 4

“1–9–2–2” = match 3

“2–3–3–2” = match 2

“1–2–1–2” = match 2

Lottery phases

Each full lottery session is completed every 24 hours (1 round per day), with the timings for each as below:‌

2 PM UTC — 1 PM UTC‌

An example of a lottery session starting at 2 PM (UTC) is as below:‌

Phase 1 — Buy Tickets (2 PM to 1 PM UTC)

  • You have 23 hours to buy tickets.
  • The lottery jackpot will accumulate at the top of the page with each ticket bought.
  • Users will receive a ticket (comprised of 4 digits) for each 0.2 Merlin paid.‌

Phase 2 — Lottery Draw! (1 PM UTC)

  • The 4 winning lottery numbers are drawn and will appear on the page.
  • Each participant’s winnings will be automatically calculated based on their ticket numbers and shown on the page.
  • Users can claim winnings if they have any.
  • Users will also be able to see the lottery results: How many users matched all 4 numbers, 3 numbers, and 2 numbers.‌

Phase 3 — Celebration and Sharing (1 PM — 2 PM UTC)

If you won, congrats! Share with your friends or in our community groups.‌

The next lottery starts in 1 hour!‌

How are ticket numbers drawn

The lottery aims to be completely random. Even though the ticket numbers given out are determined by a front-end logic, there is an extremely low chance that anyone is able to determine the 4 winning numbers ahead of time.‌

  • The 1st lottery number will be determined based on the %10 remainders of a hash encoded by the blockhash and the number of participating users at the entry deadline.
  • The 2nd lottery number will be determined based on the %10 remainders of a hash encoded by the blockhash and the total pooled Merlin balance at the entry deadline.
  • The 3rd lottery number will be determined based on the %10 remainders of a hash encoded by the blockhash and the timestamp of the last lottery participant at the entry deadline.
  • The 4th lottery number will be determined based on the %10 remainders of a hash encoded by the blockhash and the block difficulty at the entry deadline.

2. Vaults:

How do vaults work?

Vaults are automated investment instruments that utilize optimal strategies to maximize yield. Merlin uses vaults to automatically reinvest and compound deposited assets. Vaults comprise of either a single token or a pair of tokens that are invested into liquidity pools.

How often do the Merlin vaults compound?

Each Merlin vault compounds at the most optimal time according to empirical data. This usually ranges between a compound every 2–4 hours.


In this example, we show you how our non-CAKE Maximizer vault work:

  • John deposited his BTCB-BNB LP into the Merlin vaults
  • Merlin’s smart contract takes care of all the mechanics behind the scenes: Staking John’s assets into PancakeSwap, collecting CAKE rewards and optimally switching reward assets into the right ratio to auto-compound more BTCB-BNB LP
  • In this case, John will benefit from the magic of compound interest: reinvesting his accumulated interest with his principal and thus receiving an even higher amount of interest reward (aka. “interest on interest”).

CAKE Maximizer Vaults
CAKE Maximizer vaults help users maximize CAKE tokens. In a CAKE Maximizer vault, Merlin takes the rewards that come out of the original staked principle and stakes them into the CAKE auto-compounding pool. Based on our calculations, as CAKE pool is almost always higher in APY, the CAKE Maximizer vaults will result in higher overall APY. Merlin have created a CAKE Maximizer version of all vaults to give users more flexibility with their choice of rewards.

MERL Token is the token of the Merlin Lab Blockchain project, Merlin is an automatic tool that combines profits (generating double profits) with an optimized ecosystem to maximize profits safely and sustainably. Merlin undertakes monitoring from gas fees, APY tracking, optimal profit strategies to security, all to maximize farming productivity for DeFi users at the lowest possible cost (All APYs) & APR shown are inclusive of fees).

$MERL tokens are minted in proportion to BNB earned on the platform.
Multiple deflationary mechanisms are in place to reduce supply and to maintain constant upwards price pressure:
1. Buyback & Burn: 50% of the Burn contribution is used to perform market buy-backs of $MERL tokens to stabilize price during market volatility

2. Lottery: 50% of the Burn contribution will be used to purchase $MERL and injected into the lottery pot. 20% of the pot is burnt

3. Further deflationary mechanics will be introduced for $MERL ecosystem to become deflationary

As I have introduced you to this project quite specifically, I see applications which can be considered as different layers of the civic finance ecosystem. Every application is linked with another application, the same multi-functional ecosystem will be created. Their ecosystem is building I think it is a bright spot in this space and right now this is the only project I feel it deserves to be a factor in the market in the near future. There may be somewhat objective reviews and comments about it, but as we know, beyond technology, trust in this market will determine a lot, and my confidence in this project is very high. And thank you for watching this article, I will try to bring you many other quality projects in the future.
