About GLL’s Unified Crypto Interface Protocol

An estimated global crypto ownership rate at an average of 3.9%, with over 300 million crypto users worldwide. And over 18,000 businesses are already accepting cryptocurrency payments. There are also 5 million active metamask users and the number of blockchain based decentralized wallet holders are increasing at a rapid pace.

In times like these, the ease of sending crypto to phone number and email addresses, and the security of operating in a non-invasive interoperable blockchain like Kardiachain, has given birth to GrowLimitLess. We are building world’s first unified crypto interface – a protocol for the future with one and only vision, mass adoption of digital currency.

Connect multiple wallets through our unique UCI protocol

No need to remember long wallet addresses anymore

Verified ownership of wallet on chain, immutable ownership backed by OTP

Low gas fees, no problems with unsupported network based crypto sending


Cryptocurrency crime had a record-breaking year in 2021, with a new report finding scammers took $14 billion worth of crypto last year. That’s nearly twice the $7.8 billion taken by scammers in 2020, according to blockchain data firm Chainanalysis’ “2022 Crypto Crime Report,” findings. According to a recent study by ChainAnalysis, around 12% of cryptocurrencies are lost in the ether (no pun intended) and unrecoverable, because of unfortunate typos in wallet addresses, or wrong crypto sent to unsupported network.


Going by the statistics it’s quite obvious that the fear of misrouting of funds, difficulty in remembering wallet addresses and the problem of losing crypto by sending to unsupported network is only still quite inherent. GrowLimitLess is on a mission to break the above barriers and allow for easy exchange of crypto directly to phone / email / QR backed by OTP verification. All of this to drive our only mission – which is mass adoption of digital currency.


Our dApp is already live in the Kardiachain Mainnet. We allow users to easily tokenize their phone / email using our unified crypto interface protocol. Our mobile app for IoS and Android shall soon be live as well. Also, we are opening up the UCI API to allow small businesses and retailers to grow limitlessly. Have a look at the demo video to know more.


On the global marketplace

No World Wide Unified Platform:

With a plethora of wallets like Metamask, Trust, Argent, Coinbase – its very difficult to find a protocol that could house all under one umbrella.

Long Wallet Addresses:

Lets face it, its difficult to remember and also hard to look for unique network address everytime to prevent sending over unsupported crypto to wrong network.

Security and Authentic Reporting :

With the increasing scams and bad actors in the space, the good side of the crypto world gets more invisible. But there could be a more authentic way to report transactions, a safer protocol to send crypto and in the end of the day , a better inclusive way to foster mass adoption.


Our method and vision

Global Unified Protocol:

We heard you. Now, there is ease of linking multiple wallets to your phone / email through our UCI protocol and having the choice to select the primary and share your QR, to receive your desired crypto in the easiest, fastest and safest way.

Safe Secure and In Your Self Custody:

Send crypto to your friend’s email or phone number. Or share your QR and get paid instantly. Its that easy, and being built on the world’s first non-invasive interoperable blockchain, transactions are safe, immutable and retained on-chain. And best of all, receive the crypto straight to your own self custodian wallet of choice. We strongly believe ‘Your Crypto, Your Keys’.
