TL:DR;

  • Tongue is a wallet on iOS which includes your tx at the best price / time ratio.
  • Tongue is non-custodial and uses Gnosis Safe, Wallet Connect and Rockside Relayer.

DeFi is a world full of opportunities but …

Missing on a juicy trade due to poor gas price estimation might seem just slightly annoying, but the road to depression is paved with failed transactions.

It starts with a missed trade inducing a small morale dip.

Your wet blanket attitude bores your colleagues, and your friends — who don’t give a rat’s ass about DeFi — stop texting you. As you’re lying on your parents’ couch, wondering how you spiralled down so fast, getting pinged by scammy telegram groups, the final blow hits you. They: your parents, creators, hardcore followers, all-time sponsors, stopped believing in your “to the moon” speech and they are discussing your lousy trader career — eradicated before its establishment.

Don’t hit the Prozac yet, this is not your fault.

Imagine telling children to stop sending their cards to Santa because his letterbox is full. No way! Impossible! You can’t be that cruel! The blocks may be full, but hopeful transactions should be included at a reasonable gas price.

We won’t crush your hopes and dreams — we’ll get them transactions unstuck.

Introducing DDX (DeFi Degen Experience)

Tongue is a wallet that includes 100% of your transactions at the best price / time ratio. This is a crazy value proposition. Don’t agree? That’s ok, just don’t come back crying later.

Tongue works with all dApps! Easy does it: that’s us. Tongue Wallet has integrated wallet-connect. This way you can easily connect to any dApp even on mobile, and wait — what if your dApp doesn’t support it? Well, tag their team on a twitter rant and get them to integrate wallet-connect and make everybody’s life easier.

Under the hood, Tongue is reliable and secure.

Tongue is secure by design and non-custodial. Your money, not ours. We won’t touch it — we can’t touch it.

The most trusted smart contract to manage your asset : Gnosis Safe

There are currently more than 5,000 Gnosis wallets deployed, with the top 25 instances alone holding a combined volume of 1.4M Ether and more than $1B equivalent in digital assets. The Gnosis Safe core smart contracts have passed the highest possible security standard in the industry: Formal Verification.

Never miss a trade thanks to Rockside Relayer

To relay transactions, Rockside uses the concept of meta-transactions. Meta-transactions are based on the principle of off-chain message signing for on-chain use. A user signs a message representing its transaction intent. The message is then sent to Rockside. There it gets wrapped in a new transaction that is sent and executed on-chain by a smart contract. Rockside is non-custodial, smart contracts are open-source and audited.

What’s the difference with Ledger, Argent, Metamask, …

What’s the difference with other existing wallets? Not much except that we are specialized and excel at one feature: the inclusion of your transaction. What does it mean? Tongue is powered by Rockside — our core product we’ve been developing for over a year. Rockside has a replay mechanism that monitors and bumps the fees until your transaction is validated. No. More. Stuck. Transactions. Basically it saves you from actually feeling yourself get old in front of your Metamask manually replacing your gas price, over and over and — stuck. And so frigging stuck because of that nonce(ense) your wallet is blocked, you miss other opportunities and you get sent right back to reality — ope — there goes gravity -ope — your depression’s back — ope — on your parents’ couch.

Transaction fee VS block median fee

We had fun comparing the performance of our relay with one from a famous wallet. We’re hoping they might want to become a Rockside customer so we won’t reveal their name — but if you recognise yourself feel free to contact us and get your performance up.

Our relay (on the right) includes transactions 90% of the time below the block’s gas price median 😎.

Why did we spend time creating Tongue?

On the one hand, we became really fed up with stuck transactions during this food coin madness because of bad gas price estimation and on the other hand, we developed Rockside, a cool way to counter the problem, simply lacking a mobile app. We decided to clap our hands together and spend time making a wonderfully designed Tongue Wallet and releasing the app to everyone.

In the interface, you can add addresses to exit or control your Gnosis safe. if the color of the app bothers you or if you just wanted to install it to make us pay for deploying a safe contract for nothing ($20) ha-ha-ha little bastards.

Put your money where your mouth is: Tongue Wallet

That’s it that’s all. Have fun.

Thanks to Bettina Boon Falleur and Rockside crew for their help and review.
