SetDev

We help teams design, build, & secure software that runs on Bitcoin/L2s. We also occasionally ship our own tools & products like @bitscriptapp.

Easily the most relevant paper going around atm, give it a glance as it'll likely be the 'talk of town' for the conference circuit.

We'll release a thread soon on *how* quantum breaks some key parts of Bitcoin.

Many are wondering "what Google saw" that caused them to revise their post-quantum cryptography transition deadline to 2029 last week. It was this:

Bitcoin stands on decades of cryptographic break-through, key papers include:

1976 — New Directions in Cryptography
1991 — Time-Stamping Digital Documents
1997 — Hashcash
1998 — b-money
2005 — Bit Gold

What else would you add to the list? (not counting the whitepaper ofc)

Congrats to @AureoBitcoin on launching Direct to Wallet.

Send a SPEI, get Bitcoin straight to your wallet. No exchange custody. No withdrawal fees. Under 30 seconds.

Proud to be part of the engineering team.

Descriptors are a deeply underappreciated primitive; tough to grasp how much they improved output selection.

Now descriptors plus miniscript? Superpower. We love to see what devs are deving with the combo.

It's been an exciting last few years of L2 activity! For the builders, we're curious to hear your voice.

Which of the following infrastructure do you consider as a "true" layer-two?

[SetDev @SetDevBTC]

“If you have highly structured script templates you can get away with not really understanding script”. This quote observed in an IRC chat by Andrew Poelstra reflects what Miniscript helps with.

Miniscript is an incredible tool in standardizing templates for Bitcoin Script.

@blockworksDAS (DAS) week in NYC 👀

We'll be around the conference & side-events, ping us if you want to talk UTXOs, P2TR, or VTXOs!

[SetDev @SetDevBTC]

@ArkLabsHQ @tether @egodeathcapital @Anchorage No surprise here, killer tech, team & ecosystem.

Cheers 🥂

OP_1SUB! For whenever you'd like to subtract one from your script stack Not widely used, but as with any stable language, a pillar of basic arithmetic.

@januszg_ @OPNEXT2026 @btcplusplus @TheBitcoinConf Ah, wasn't on our radar. NYC <> LV <> MIA is quite the circuit.

[SetDev @SetDevBTC]

Conference season is *right* around the corner! Just in April we have:

- @OPNEXT2026 (16th)
- @btcplusplus (23rd - 24th)
- @TheBitcoinConf (27th - 29th)

Any other that we're missing??

[SetDev @SetDevBTC]

Ever catch yourself wondering, "How can I increase the top item of the stack in script?" Well, use OP_1ADD of course! Typically not used in standard scripts, but seen in puzzles and script challenges.

Fascinating to watch the agentic wallet game heat up!

If you're in the hard money space we recommended checking out both AIBTC (@aibtcdev) & Claw Cash (by the @arkade_os team).

Both primarily focused on Bitcoin & built by first-rate teams 🦞🦞🦞

Doing a lil’ fireside chat w/ my dear friend @wsfoxley at tonight’s @CryptoMondaysNY

Meet us at PubKey at 6:00 pm for Wills breakdown on what 2026 has in store for Bitcoin!

[SetDev @SetDevBTC]

They're not a client (~yet~) but @joinMagnolia is easily one of the teams to watch in 26'.

Kudos on all the progress gentleman.

1/x Last month we quietly shipped something small.

A dlc oracle that allowed for trustless bitcoin backed loans. No custodians in your loan.

This month we're launching something big.

An oracle that monitors a real bank account for repayment, and issues loans in real dollars.

[SetDev @SetDevBTC]

The four year cycle theory is falling apart. Bitcoin didn’t follow the script in 2025.
Good. Bitcoin was never supposed to be predictable. It was supposed to be reliable.
Those are two very different things.

An audit isn’t a checkbox. It’s a second set of eyes before the world becomes your QA team.
