UGTP (Universal Gasless Transaction Platform) is the technology behind EXTRA SAFE's transfers, enabling a gasless experience for users. You send USDT, and pay the gas with a fraction of your stablecoins, like USDT. You never need to hold AVAX or any other native cryptocurrency to make a payment.
The problem UGTP solves
Every blockchain transaction requires a gas fee – a small payment to the validators who process it. On Ethereum and most other chains, gas must be paid in the network's native token (ETH, AVAX, etc.). This creates a frustrating catch: to send USDT, you first need to buy and hold AVAX ot ETH just to pay the fee. Most people who want to send digital dollars don't want to manage two currencies. UGTP removes that requirement entirely.
How UGTP works
UGTP is built on the ERC-4337 Account Abstraction standard – the same technology that powers smart contract wallets across Ethereum and compatible chains. The key component is called a Paymaster: a smart contract that pays the gas fee on behalf of the user.
In EXTRA SAFE, here's what happens when you send USDT on Avalanche:
1.
You tap Send in a chat and choose an amount.
2.
Your wallet prepares the transaction and submits it to the UGTP Paymaster.
3.
The Paymaster pays the AVAX gas fee on your behalf.
4.
A small USDT amount (the gas equivalent) is deducted from your transfer or charged as a fee.
The transaction is confirmed on Avalanche C-Chain in approximately 2 seconds.
From your perspective: you sent USDT. That's it. No AVAX, no gas estimation, no separate fee currency.
UGTP and ERC-4337
ERC-4337 Account Abstraction is an Ethereum standard that enables programmable wallets – wallets that can follow rules, delegate signing, and sponsor gas. UGTP implements ERC-4337 on Avalanche C-Chain (which is EVM-compatible and supports the standard).
This means EXTRA SAFE wallets are smart contract wallets, not traditional EOA (Externally Owned Account) wallets. You get the same self-custody guarantees – your keys, your funds – with a dramatically better user experience: no gas token anxiety, no failed transactions because you ran out of AVAX.
What UGTP is (and isn't)
- •
UGTP is not custodial. You still hold your private keys. EXTRA SAFE has no access to your funds.
- •
UGTP is not free. Gas fees are real and are covered by a deduction from the transferred USDT or a small service fee. The cost is transparent and shown before you confirm.
- •
UGTP is not exclusive to EXTRA SAFE. The underlying ERC-4337 standard is open. UGTP is EXTRA SAFE's implementation of it on Avalanche.
Q&A
Do I need to do anything to enable gasless sending?
No. UGTP is enabled by default for all in-chat USDT transfers on Avalanche. You don't need to configure anything.
Is there a fee for UGTP?
Yes, but it's minimal – a fraction of a cent. The fee is shown transparently before you confirm. You never pay in AVAX; the fee is calculated and deducted in USDT equivalent.
What if I want to pay gas in AVAX the traditional way?
UGTP is the default for in-chat transfers. Standard wallet sends (from the Wallet tab, to an external address) may offer traditional fee options depending on the network and transaction type.
