Surge Credit

The reason most Bitcoiners use custodial lenders isn't ideology. It's UX. Non-custodial has been clunky, slow, and more expensive — until it wasn't. Full walkthrough of what changed. Link in replies.

Defining our core custody thesis, one term at a time. Taproot Vault: collateral that never leaves Bitcoin: no custodian, no bridge, no wrapper.

Surge Protocol — Week 14. 11.33 BTC locked. Steady and stable. But the story this week isn't on the throughput chart. ~$3M in credit-line demand. 99% pool utilization. 8.2% average lender APY over the trailing 30 days. Every dollar of supply is deployed. Demand is queued behind it. Rates found their clearing level and are holding. No subsidies. No rebate campaigns. Just a market pricing itself, on both sides, on a non-custodial protocol. If you're an LP looking at verifiable Bitcoin-backed yield, there's real demand waiting to meet new supply the moment it lands. Audits continue. Heads-down.

"This is the lowest sentiment I've ever seen on bitcoin." @LynAldenContact says this bear feels worse than 2022 despite higher prices.

You've seen the app. You've never seen what holds it up. That's the thing most people miss about surge: it's two layers, and the layer you touch isn't the one that matters. 1️⃣ The app is just glass. surge on iOS and Android, the earn app, and soon third parties launching yield and credit products to their own users, non-custodial, all on the same rails. interfaces come and go. anyone can build one. 2️⃣ The protocol is the part that holds. Taproot vaults, the DCN, unilateral exit, non-custodial by construction. no rehypothecation, borrower-controlled collateral, verifiable on-chain. it doesn't bend for any app sitting on top of it. That's why it's built this way. swap the app, add ten more, hand the keys to a third party, the custody model, the exit path, the math don't move. no interface can rewrite rules it doesn't own. Judge the protocol, not the app.

This week at Surge All-time highs across the board — APR, APY, and BTC locked in Taproot vaults. Demand and supply both climbing, all of it verifiable on-chain. 1️⃣ Tue: the Taproot series, wrapped: NUMS, Repayment, Liquidation, Unilateral Exit 2️⃣ Wed: Borrower's Wisdom on what "term" really means for a credit line (not what a mortgage taught you) 3️⃣ Thu: Week 13 stats — the ATHs, on-chain Don't trust.

Nice seeing organic growth in @surge_credit this morning.

Surge Protocol — Week 13. 11.44 BTC locked. Steady tick up. But the story this week isn't on the chart. Highest-demand week Surge has seen : APR, APY, and borrow requests all at all-time highs. On the supply side, new liquidity providers came in to meet it. That's what a real market looks like. Rates rising because demand is honest. Lenders showing up because the yield is honest. Also shipped this week: Extend Credit Line and Delinquency handling. Both features protect lenders, the market only works if both sides trust the rules. Audits continue. Heads-down. Don't trust.

We have completed our planned maintenance period. No action needed from your side.

We are starting our planned maintenance period now. Will keep everyone updated here. No action needed from your side.

Scheduled maintenance: July 2, 13:30–15:30 UTC (2 hrs). Surge.credit will undergo scheduled maintenance across both the mobile apps and the protocol. ⚠️The full system will be temporarily unavailable during this window, please plan any actions ahead of time. ➕This release ships Extend Credit Line and Delinquency. Full details to follow. 🟢 Your Bitcoin stays safe throughout: BTC remains secured in your Taproot vault for the entire window. Don't trust, verify.

6/ The playbook: stop asking "how long do I have?" Start asking "how much price movement can my buffer absorb?" Manage the position, not the calendar. Set your draw LTV first, and let it, not a term, decide how much you borrow. Don't trust. Verify 🟧

5/ Thinking in loan terms actively hurts you. It pulls attention toward a date and away from the buffer, so people take a comfortable-sounding term, draw too aggressively, and get liquidated well before that date ever mattered. The deadline was never the risk. The draw was.

1/ Borrower's Wisdom 🧠 Loan term decides everything on a mortgage. On a Bitcoin-backed line, it decides almost nothing. If that surprises you, you're managing the wrong number. 🧵👇

7/ Bitcoin lending failed last cycle because trust scaled with the book. The architecture above is the opposite trade. Every Vault is the same construction. The credit book grows. The thing you have to trust does not. Don't trust. Verify. 🟧

6/ Exit: the leaf that doesn't need us CSV timelock, then your signature alone. Reclaim your bitcoin without permission, without counterparty, without any clause that assumes we still exist. A recovery guaranteed by bitcoin script.

5/ Liquidation: the leaf the industry hides Decentralized oracle today, multi-source tomorrow. m-of-n threshold signing, not a custodian. Permissionless Dutch auction on Base, BTC delivered on bitcoin. 50% to draw. 90% to liquidate. The space between is a runway.

4/ Repayment: the cooperative leaf Two signatures. Yours and the DCN's. Neither moves alone. A vaultId committed in the script isolates every Vault, a witness for one can't be replayed against another.

3/ NUMS: the key no one can sign for The internal key on every Vault is derived from SHA256("SURGE-NUMS"). No private key exists. The key-path backdoor is structurally dead. Don't trust that we won't move your coins. Verify that we can't.
