Exchanges, payment processors, marketplaces and merchants all accept stablecoin deposits, but each needs a different workflow.

Here is how each one runs its stablecoin operations on MPCVault: https://t.co/n9P6pKVHSF

@BitcoinMagazine @watchbmtv @GraceRemiTV @realseanhagan Bitcoiners have been saying 'split your keys' for a decade. US regulators just wrote it into the definition 👇

[MPCVault | crypto banking for institutions @mpcvault]

@CryptosR_Us the custody part:

[MPCVault | crypto banking for institutions @mpcvault]

@WuBlockchain also interesting how the custody section redefines what a private key is 👇

[MPCVault | crypto banking for institutions @mpcvault]

@EleanorTerrett @USOCC Unpopular opinion: everyone's fighting about stablecoin rewards, but the bigger change is two words in the private key definition 👇

[MPCVault | crypto banking for institutions @mpcvault]

@RippleXrpie The new rules now treat a private key as something that can be split into shares. The money gets regulated, and so does who holds the keys.

[MPCVault | crypto banking for institutions @mpcvault]

@SecScottBessent 1863 standardized the money. 2026 quietly standardized who holds the keys: the OCC now treats a private key as something that can be held in shares. No single person controls the money.

[MPCVault | crypto banking for institutions @mpcvault]

@Cointelegraph Most interesting line in the custody section:

the OCC now treats a private key as something that can be held "in shares." Split keys just went mainstream.

[MPCVault | crypto banking for institutions @mpcvault]

The OCC's final GENIUS Act rule now defines a private key as material held "in whole, in shares, or reconstructed ephemerally."

Regulators wrote split keys into the rulebook. We've built on exactly that idea: no single person holds the whole key 🔑

[Cointelegraph @Cointelegraph]

🇺🇸 BREAKING: The US OCC finalizes GENIUS Act rules for stablecoin issuers, covering reserves, redemptions, and custody.

Effective January 18, 2027.

[MPCVault | crypto banking for institutions @mpcvault]

@WatcherGuru Scammers only need to fool one person. That's why we split keys so no single person can move the funds.

[MPCVault | crypto banking for institutions @mpcvault]

@WatcherGuru Issuance rules are done. Now the boring part that actually matters: every company holding stablecoins needs more than one person to approve a transfer. That's what we build for.

Automated deposit collection is now live on MPCVault!

For businesses that accept stablecoin deposits at scale, the supporting infrastructure quickly becomes a significant engineering commitment.

@Cointelegraph $891B in a quarter. The real question nobody's asking: how many of those were approved by just one person 🤔

Our founder Jason @lxjhk on why the P-256 news matters. This is the curve behind passkeys and a lot of everyday logins, and the long-running question about where it came from finally has an answer.

[jason @lxjhk]

so to explain a little bit more for everyone: bitcoin and ethereum avoided the traditional P-256 curve developed by NIST, because it was suspected that the NSA handpicked some kind of secret value when generating it, so they could build a hidden weakness into the curve and therefore, they could decrypt any communication that used this curve for ECDSA.

so bitcoin went and chose a different curve instead — the K1 curve (secp256k1), whose parameters looked transparently chosen, no mysterious NSA numbers attached.

but anthropic just found and proved that the old curve's seeds were actually generated at random. turns out it was just a 1990s random number generator seeded with the computer's clock — P-256's seed is literally the 1,842nd batch of random bytes after 1997-08-16 01:52:34. that proves the curve was secure all along, and there was never a backdoor.

and this actually matters, because while bitcoin and ethereum use the K1 curve, most other applications are still on P-256: passkeys, a huge share of HTTPS connections, SSH keys, sign in with apple and etc.

billions of signatures every day, on a curve that's now proven clean!

3/ This is how MPCVault has worked since day one. If you want to see what setup looks like without a seed phrase, the app’s free to try 👇

1/ Where was your seed phrase the first time you saw it?

[MPCVault | crypto banking for institutions @mpcvault]

2/ On a screen or generated by a device you didn’t build. Everything you did after that was protecting a secret that had already been displayed once.

MPC wallets never have that moment. The key exists only as pieces, made separately, never joined.

Seoul approves in Korean. São Paulo runs payroll in Portuguese. Berlin reviews compliance in German.

MPCVault now speaks 16 languages. One vault, zero translation risk.
