Tanken: Automating Wallet Refills for a Seamless Crypto Experience
Tanken is Here, LI.FI is Excited
Introducing Tanken. It’s a company built for a multi-chain world, powered by LI.FI!
Tanken automates the process of wallet refills. This is a massive upgrade to the crypto experience. With Tanken, you will never again have to visit a bridge, on-ramp, or CEX for gas, as Tanken allows users and protocols to effortlessly add funds to their wallets in just a few clicks.


The Details
Through a Tanken subscription, users can set certain wallet balance thresholds to trigger a refill once hit. Along with refilling wallets, Tanken offers a variety of notification methods to track address balances, events, and more.
There are two entities that automatic gas refills should lead to major, major user experience upgrades.
Protocols — dApps that use any form of on-chain distribution to users from protocol-owned wallets can automate gas refills to ensure that airdrops, staking rewards, DAO payments, and/or NFT mints.
Multi-chain crypto users — anybody worth their Degen Score in crypto is using multiple chains at this point. One of the biggest pain points for the entire space is getting gas on a new chain or adding gas to a wallet on a chain when you are running low. Tanken can automate this, starting with support on Ethereum, Polygon, and Avalanche.
Let’s dive a little deeper into the second use-case, which most readers here will be able to relate to personally:
Explaining Tanken in English
Simply enough, users can set rules like “if my MATIC wallet balance on Polygon is worth less than $5, please refill my wallet with an additional $5 in MATIC.” Another example would be: “if I am about to get liquidated on Aave, please top up my position with $5,000 in USDC.”
This is quite powerful. Especially in a cross-chain world, where bridging can make refills even more necessary.
An even simpler example:
Imagine. You are on BNB Chain, making a swap on PancakeSwap. You trigger a trade with the last of your gas to swap from CAKE to USDT because you are a trading genius. But then, a few days later, ARB drops and you want exposure.
Your USDT is now stranded on BNB Chain. What do you have to do? You have to buy BNB from a CEX, withdraw to BNB Chain, and then bridge your USDT to Arbitrum.
And then, once on Arbitrum, you have to make sure you have enough ETH to swap the USDT to ARB.
If you don’t have enough ETH on Arbitrum, you have to go buy ETH from a CEX, withdraw to Arbitrum, etc.
You see the issue?
Tanken = problem solved. It is a cross-chain wallet refiller.
Here’s How Tanken Works
Ok, so how does Tanken work?
Refills are simple.
Select the wallet you want refilled. Create a source wallet that will fund the refills. From there, Tanken leverages LI.FI to programmatically bridge and refill the destination wallet from the source chain.
From there, you can program your refills by…
currency
on-chain vs off-chain settlement
wallet balance to trigger refil
value of refill
max refill

Conclusion: LI.FI x Tanken is Fantastic
The entire point of LI.FI is abstraction. We are a liquidity router for crypto businesses. LI.FI is one API that connects tokens across 20 blockchains. LI.FI is an out-of-the-box solution for crypto businesses to connect liquidity across any blockchain without interacting with bridges, DEXs, or chains – our contracts do all this automatically in the background. We offer users and developers a super streamlined interface for interacting with cross-chain transactions; be it swapping, purchasing an NFT, or bridging some type of data.
But we can’t do this ourselves. LI.FI is not really meant for users, it’s meant for crypto businesses to come in and build new use-cases on top of.
So far, these use-cases have been limited to existing businesses adding LI.FI into an already-built application.
Wallets can embed LI.FI to power cross-chain swaps (like BlockWallet has done). dApps can integrate LI.FI to implement cross-chain deposits (as Superfluid has done). On-ramps can use LI.FI to expand their token offerings to low-cap tokens on L2s (which Kado recently did).
But that changed today.
Because finally, FINALLY, someone (Tanken) has built something entirely new on top of LI.FI.
And we think it’s pretty cool.
So go join Tanken’s whitelist to try out their application. And come tune in to our Twitter spaces later this week for more information.
