Tether Wallet, The People's Wallet

Tether has achieved the widest financial inclusion success story in the history of humanity.

For more than a decade, Tether has built its company on a simple mission: bringing financial inclusion to the billions of people, primarily living in developing countries, who were left behind by the traditional financial system, those who never had access to basic financial services, and those who live in high-inflation countries.
This number is higher than most think, almost half of the population of the world.
As of March 2026, Tether’s technology is used by more than 570 million people globally, with adoption continuing to accelerate across emerging and developed markets alike, at the pace of tens of millions of new wallets added per quarter.

With tether.wallet, that entire infrastructure, the widest and most granular money distribution network built by humanity, becomes directly accessible to end users for the first time.

Features:

- 100% self-custodial with simple backup user experience (one click encrypted secret backup/restore with your cloud account or simply export the 12 words); only you are in control of your funds; no middleman or intermediaries.

- Assets available: only people need; Bitcoin, Digital Dollars (USDT, USAT) and Gold (XAUT).

- Bitcoin: on-chain, lightning network and spark support

- USDT/USAT/XAUT: supported blockchain list will expand rapidly within next 30 days; USDT0 is already integrated; soon TW will implement seamless swaps across all chains -> insane user experience

- Send transaction user experience perfected for the people; gasless send for USDT/USAT/XAUT, i.e you don't need to own/buy/deposit gas tokens (ETH, TRON, ...) etc to send assets; the Wallet solves all the complexity for you behind the scenes (via paymaster)

- One address: generate your [at] https://t.co/rAv6VOWWjO address to receive/send assets to any other tethered wallet -> unparalleled user experience

- 100% built on WDK by Tether, our open-source Wallet Development Kit

Please share your feedback and thanks for all you support.
We're unstoppable together ❤️

We’re making it easier for millions of businesses to accept bitcoin.

Starting today, eligible U.S. @Square sellers will begin having Bitcoin payments automatically enabled.

Sellers who accept bitcoin will receive USD as default.

This is how bitcoin as everyday money begins.

We love @mpp + BTC. Grateful to have helped shape how Bitcoin payments could work within it.

[Matt Huang @matthuang]

A few things I like about MPP (machine payments protocol)

Payment-method agnostic (supports stablecoins on Tempo, Stripe, cards, Bitcoin lightning, etc)

Open and extensible (without our permission)

Streaming payments (via state channels)

Minimal and efficient

My agents are Spark-pilled. I literally taught it how to use spark 3h ago and it took my money and decided to onboard other agents.

Bitcoin is the only way
