Tetrapolar

Bitcoin-native settlement for global trade. Secure, non-custodial, discreet.

[Yuri Yerofeyev @yuvlero]

With Milestones, @TetrapolarHQ will be able to cover the vast majority of escrow use cases.

You’ll be able to hire a construction crew and pay them in parts, but they’ll see the whole amount right there.

You’ll be able to engage in multi-step international trade.

And so on.

Tetrapolar #002 - How A Tetrapolar Deal Works

[Tetrapolar @TetrapolarHQ]

7/7
The most expensive failures happen where nobody is looking. We build for structural resilience: minimal, auditable, and designed so compromise of any single point is insufficient.

1/7
Coldcard lost 1,082 BTC ($70M) in 41 minutes due to flawed random number generation in firmware. The question every Bitcoin company must answer: who generates your keys, where, and how?

6/7
You hold part of the 2-of-3 multisig yourself. Your key is generated in your browser and backed up on your terms. An exploit at any single layer is survivable. No blind trust in hardware, firmware, or entropy sources required.

You can already sell your art for BTC or USDT on @TetrapolarHQ.

Soon, you’ll be able to hire a contractor to build your house and pay in milestones.

We’re just starting!

Tetrapolar #001: Why I built Tetrapolar (@TetrapolarHQ)

[Yuri Yerofeyev @yuvlero]

Next step: use a neutral non-custodial escrow for bitcoin and USDT at @TetrapolarHQ.

[Tetrapolar @TetrapolarHQ]

We have reduced the number of steps that Buyer and Seller have to take to fund the deal from 3 to 1: deal creation and acceptance now include payout/refund address forms. As soon as the deal is accepted, it can be funded right away. No extra steps.

4/ Most custodial escrow depends on the company staying online. We don't.

1/ If Tetrapolar disappeared tomorrow, every BTC deal done on the platform would still be recoverable. We just wrote the tutorial that shows you how. No magic. Just cryptography.

[Tetrapolar @TetrapolarHQ]

3/ This is 2-of-3 multisig in practice. Both parties independently recover the wallet, then coordinate signing without us in the loop. The escrow works even if the coordinator is dead.

[Tetrapolar @TetrapolarHQ]

We have increased our open beta deal limits to $250,000, opening up to more usecases.

Selling a car for BTC? Buying an apartment with USDT?

Tetrapolar will secure your deal with multisig, non-custodially!

Tetrapolar's founder @yuvlero is back on X to test whether the algo has indeed been fixed.

Give him a follow!

Businesses are shifting USDT use from speculation to operational settlement: supplier transfers, contractor payouts, and cross-border receivables.

The stablecoin is functioning as payment infrastructure, not a trading instrument.
