VAULT: Building a Gasless Stablecoin Wallet

2025-12-11

Stablecoins are everywhere now.
Over $225 trillion in transaction volume since 2019, surpassing global GDP.

And yet, the moment a regular person tries to use one, they hit friction: gas fees, multiple apps, confusing recovery phrases, and the need to hold native tokens just to move money.

We’re not fixing everything.
We’re fixing what comes first.

The Core Observation

Stablecoins work. As a medium of exchange, they already solve real problems: cross-border payments, remittances, freelancers getting paid instantly. But the user experience is stuck in 2015.

To send money, users still need to understand:

Gas mechanics
Native tokens
Sidechains and bridges
Wallet fragmentation

There’s a huge disconnect between “this should be as easy as Venmo” and “first, learn how EVM gas works.”
That gap is what VAULT was built to close.

The Team

VAULT was built by HighTower and AdSkill — teams from very different worlds.

HighTower comes from Web3 infrastructure. We run validators, build network tooling, work closely with new protocols, and understand stablecoin flows at the infrastructure level. We know what it takes to make blockchains work in production.

AdSkill comes from Web2. They’re a leading marketing agency working simultaneously with Web2 and Web3 companies. During a strategy session, a simple insight emerged:
the market needed a stablecoin wallet without friction.

A wallet where users could:

Send stablecoins across networks
Keep full self-custody
Avoid native tokens entirely
Just move money

We built VAULT for ourselves first — then realized everyone else had the same problem.

Timeline: From Idea to Product

May 2025 — Project Start

HighTower and AdSkill align on a shared vision:
build a self-custodial wallet that feels like a bank app, without blockchain barriers.

June 2025 — Architecture & MVP Scope

Key decisions:

PWA on Next.js for fast iteration
iOS and Android clients
Tron + USDT as the launch network (real volume, real adoption)
Gas abstraction as the core breakthrough

Gas abstraction means users send USDT without holding TRX.
Transaction fees are paid in USDT, the same asset being transferred.

July 2025 — MVP Complete

Gasless transactions working in production
Strategic decision: split product into regional versions
Clear positioning instead of “everything for everyone”

August 2025 — Beta & Mobile Development

iOS and Android apps submitted for review
Closed beta with 50–100 early users
Key insight: gasless UX clicks instantly
Main friction: seed phrase onboarding
UX refined based on real feedback

What’s Next

Q1 2026 — Access & Expansion

Fiat on-ramps for instant purchases
Multi-chain expansion across EVM networks

Cross-chain asset movement across supported networks

Gas abstraction is the foundation. Everything else builds on top of it.

The Takeaway

We know VAULT works because we use it.
We know people want it because the reaction is always the same:

“Why doesn’t every wallet work like this?”

People move money across borders.
They get paid in unstable currencies.
They want control.

These aren’t crypto problems — they’re real-world problems.
Stablecoins already solve them. VAULT makes them usable.

We’re betting people will use stablecoins as actual money if the experience is simple enough.

We’ll see if that bet pays off.
