Fun to see @markymark hacking on agentic payments. Potential use case ➡️ Automated re-staking into @Stacks ? You lock STX to support the network and earn BTC rewards. But optimizing it manually is a pain: • Rewards come in irregularly • Pool minimums and lockup periods vary • Gas fees fluctuate • You need to decide when to re-stack vs. hold liquid With an agentic wallet: You set a policy: "Re-stack my STX rewards automatically when balance exceeds 100 STX, fees are reasonable, and I'm not in a lockup period. Alert me if APY drops below 5%." The agent: 1. Monitors your STX balance as rewards trickle in 2. Checks current stacking pool rates and lockup terms 3. Waits for fee conditions to align 4. Builds the stacking transaction (dry-run) 5. Executes silently if within policy — or pings you if something's off (APY dropped, pool changed terms, etc.) You're not babysitting your wallet daily. The agent handles the routine compounding; you only get pulled in for exceptions or policy decisions. Basically: set the strategy once, let the agent execute, stay in the loop only when it matters 🤔 markmhendrickson.com/posts/a…

Eventually, as a result of the context limitations of AI agents, we’ll start to change and improve our work practices to aid in their success. One of the most interesting issues with AI agents is because of their inherently limited context, they simply don’t know what they don’t know. They come in as a superintelligent system, but have none of the signal that humans could rely on implicitly for making decisions. For instance, if you ask a question of an agent that has a right answer but other plausible answers that are wrong because of enterprise data that’s out of date or wasn’t comprehensive, when should the agent stop trying to find new information that verifies or invalidates the answer it found? This is a super hard problem because you run into a latency vs. accuracy trade-off that’s quite hard to get perfect. This is why the future of work is going to look quite different because we can’t take for granted that an agent will work on the right information if they don’t have accurate, up-to-date authoritative sources of truth to work from. This will subtly then change our own workflows in the enterprise to ensure that agents are able to be effective.
Everything we're doing to make codebases "agent-ready" (better docs, less dead code, smaller surfaces) engineers always needed too. Agents just have zero tolerance for the entropy humans learned to work around. They can't "just know" a file is outdated or a code path is dead. They take your codebase at face value, which means it finally has to be worth taking at face value.

🚨 sBTC/BSD trading pool is live on @bitflow Very excited to announce our first trading pool. Bitflow will give BSD more liquidity, tighter peg behavior, and better tools for borrowers. Bitflow already has the deepest sBTC liquidity on Stacks, making them an ideal partner for BSD. Let’s dive into the key benefits from this pool: 💵 Peg maintenance via arbitrage BSD/sBTC liquidity helps arbitrageurs maintain the BSD peg. – If BSD < $1 → buy BSD on Bitflow, redeem for $1 of sBTC via BSD vaults. – If BSD > $1 → mint BSD against sBTC, sell into the pool. This is a proven mechanism that allowed Liquity to maintain their peg for the last four years. 🔄 Looping and leverage With the Bitflow pool, borrowers can loop BSD: Borrow → Swap to sBTC → Add collateral to vault → Borrow more. This is not paper leverage, the actual sBTC backing your loan, and earning dual-stacking yield, increases each loop. Looping does add risk: you would need liquidity to unwind and a more aggressive collateral ratio. DYOR; this is not recommended for conservative borrowers. ⚖️ Swap into other Stacks assets BSD already offers the cheapest Bitcoin-backed loan in existence. Now you can multi-hop into any Bitflow-routable SIP-10 asset and put those borrowed dollars to work—for example: BSD → sBTC → STX to earn Stacking yield. ↗️ Exit to exchanges or fiat Need dollars off-chain without selling BTC? You can borrow BSD, swap back to sBTC, and then exit to any exchange and from there to dollars. More routes should become available as Stacks upgrades USDC and liquidity increases. Huge thanks to the Bitflow team! Trade sBTC/BSD at app.bitflow.finance/

gm @circle 🟠 Circle’s first move into Bitcoin DeFi is happening on Stacks, the only Bitcoin Layer 2 in their pilot launch of Circle xReserve. Circle xReserve is enabling Stacks to bring a USDC-backed stablecoin to Bitcoin DeFi.

The Bitcoin Synthetic Dollar (BSD or “Based Dollar”) is live on Stacks. Our private beta starts today. BSD is a digital dollar built on Stacks and collateralized with sBTC. With BSD, you lock your Bitcoin as collateral and borrow digital dollars. Lock BTC, borrow USD—hold forever, spend today, never sell a satoshi. Why Bitcoin lending? Over a year ago, we declared “Bitcoin will not become money; it will become the best and last collateral on earth.” Our thesis has been largely validated by ETF inflows, institutional adoption, and a proliferation of Bitcoin L2s and lending products. All of these developments point away from Bitcoin as digital cash and toward Bitcoin as collateral. Bitcoin lending is the obvious product aligned with this future. How does BSD work? The protocol uses an over-collateralized lending model—similar to Maker, Liquity, and historic gold-backed currencies. We’ve taken hard-earned mechanism design knowledge from those protocols and brought it to Stacks and sBTC. This design gives Bitcoin holders superpowers: • Keep Your Stack – Borrow dollars, retain full BTC upside. • Flexible Credit Line – Borrow/repay anytime, no fixed terms, no rollover fees. • Low APYs – BSD has no fiat funding cost → structurally lower rates than any centralized loan. • User-Set Rates – Dial your own interest rate; trade cost vs. redemption risk. • Decentralization – Collateral locked in Stacks contracts. No custodians, rehypothecation, or counterparties. What is live today? BSD is in private beta on Stacks mainnet. Approved Stacks principals can use the full protocol; however, there is a global collateral cap during the beta. For beta access, DM @bsdmoney. Learn more at: bsd.money What is next? • Rebates! We’re launching a rebate program where BSD holders that provide liquidity will have all their borrowing fees rebated. We plan for this to include all protocol fees, but only rebate LPs—the net effect should be zero, or slightly negative, interest rates. • AI copilot: We’re putting the finishing touches on an advanced AI copilot that can answer any question about the protocol, has full read access to protocol state, and can monitor your vaults and help you make critical decisions on collateral ratio and interest rates. • Security: We’re going to conduct additional audits and bug bounties during the beta. • Partnerships: Dual stacking, liquidity pools, and more TBA. More updates soon! Hold forever. Spend dollars. Become a legend.

In honor of Earth Day, today’s @LeatherBTC Lounge explores one of the most misunderstood aspects of Bitcoin: its relationship with energy and the environment. The mainstream narrative often stops at the idea that Bitcoin consumes a lot of energy. What’s often missed is the broader context - the kind of energy being used and how Bitcoin mining can help scale clean infrastructure, reduce waste, and create powerful incentives for renewable innovation. It’s a theme we’ve explored before with guests like Bitcoin philosopher @thetrocro and @BTC_Grid, founder of Constellation Heating, who demonstrated how mining can repurpose waste heat and lower emissions. Our guests Joshua Phelps and Mark Smith are the cofounders of Carbon Country, an innovative project that integrates solar farming, regenerative agriculture, and Bitcoin mining to revitalize American farmland, sequester carbon, and increase access to sustainable energy. They’re also active contributors to the @Stacks ecosystem, where they operate validator nodes! Their work represents a multifaceted approach to Bitcoin that expands its utility and drives real-world impact. This is a powerful and timely conversation about why Bitcoin is not only compatible with environmental goals but can help advance them. Join us at 11am ET 🌎 riverside.fm/studio/leather-…
This Earth Day, we’re highlighting how Bitcoin mining is good for the planet. 🌎 On the next Leather Lounge, we’re joined by Josh Phelps & Mark Smith of Carbon Country to explore how Bitcoin mining + solar farming can: 🌱 Regenerate land 🚜 Save small farms ⚡ Scale green energy
