Spark

Inside Spark’s loss absorption & risk frameworks. Spark’s security architecture is designed around: • bounded capital movement • explicit loss absorption layers • coordinated liquidity management • multi-layered oracle systems • constrained automation under governance-defined limits This deep dive breaks down how Spark structures risk, liquidity, and loss absorption across Spark Savings, SparkLend, and the Spark Liquidity Layer before losses propagate toward user deposits. Including: • updated loss absorption waterfall • Prime Agent risk capital • Genesis Capital Backstop • oracle and killswitch architecture • programmatic liquidity coordination • constrained allocation design under stress Security by design. Resilience by architecture. See what sits between losses and user deposits: @spark-11/spark-security-framework" target="_blank" rel="nofollow noopener">paragraph.com/@spark-11/spar…

Over 2,748 wBTC supplied as collateral on SparkLend since its March launch. What stands out is the pace. That supply moved in within three days, as borrowers refinanced existing BTC backed positions into SparkLend. The number reflects what the market was already signalling. BTC backed borrowing demand was never the constraint. It was the absence of venues built to handle it, and when Spark built one, capital followed. Borrow & Lend here - app.spark.fi/borrow

SparkLend’s ETH borrow market is currently operating below broader market borrowing rates. Current conditions: • ETH borrow rate: ~1.84% • $743M borrowed • 70% utilization • 90% kink utilization This is a function of how the market is parameterized. The variable borrow rate at the kink tracks the 2-day average stETH yield minus 10bps, aligning borrowing conditions more closely with ETH staking dynamics. As long as utilization remains below the kink, the market avoids the aggressive rate escalation seen in high-utilization environments. The goal isn’t temporary rate competition. It’s scalable ETH-denominated credit infrastructure with more predictable liquidity conditions. Borrow here - app.spark.fi/borrow

When the Credora rating launched, @sparkdotfi Savings USDT had $307M in TVL. Today: $1.2B.

@Zyfai_ @ethereum ⚡️

🥉 @sparkdotfi ETH vault on @ethereum ・ 1.82% base APY + 2.47% rZFI APY = 4.29% total APY ⬆️ Spark combines strong yield with one of the safer profiles on the market, while also distributing points to depositors.

The hard part is not finding yield. It is knowing when to move and when not to. That is where Zyfai Agents have the edge. Here are last week's top USDC and ETH opportunities 👇🧵

SparkLend’s wBTC deposit cap is increasing from 3,000 to 30,000 wBTC. Since launch, the initial cap has been nearly fully utilized. Demand for BTC-backed borrowing on a second on-chain venue was real, and it came fast! This increase is managed through the cap automator mechanism. In practice, new capacity will open at up to 500 WBTC every 12 hours, scaling exposure gradually rather than all at once. Put your wBTC to work on SparkLend. 👇 app.spark.fi/markets

SparkLend ETH deposits have doubled in the last month, reaching 516k. SparkLend ETH only allows efficiency-mode looping against Lido wstETH.

ETH is flowing into Spark. Since April 18 market volatility, Spark Savings ETH deposits have grown from 8,500 ETH+ to over 93,000 ETH. On April 23, roughly 30,000 ETH was deposited in a single day. The inflow moved into yield infrastructure that was already in place. Spark Savings ETH earns yield through the Spark Liquidity Layer. Explore Spark Savings 👇 app.spark.fi/savings/mainne…

Notice on SparkLend: BTC efficiency mode will be deprecated. Spark will deprecate BTC efficiency mode on SparkLend as part of ongoing risk management. The change is expected to take effect on June 4. Any positions borrowing cbBTC using LBTC or cbBTC as collateral that remain open after that point will be subject to forced liquidation on June 8. If you have an open BTC efficiency mode position on SparkLend, please close it by June 7. This notice applies to BTC efficiency mode only. All other SparkLend markets and positions are unaffected by this change. BTC efficiency mode deprecation timeline: June 4 — BTC efficiency mode deprecated June 8 — Remaining positions liquidated This notice is issued in advance to give all affected users time to act.

SparkLend is now the largest wstETH holder in the world! SparkLend is the largest and most liquid venue for ETH looping, e-mode enabled for wstETH collateral exclusively. See more here: app.spark.fi/markets

Spark’s institutional services are built for platforms that need infrastructure, not just access. Liquidity as a Service: Programmatic, risk-bound liquidity through the liquidity orchestration layer. Builders use it to help bootstrap markets and scale liquidity for stablecoins, protocols, and chains. Yield as a Service: Institutional-grade savings infrastructure that platforms can embed directly. Exchanges, custodians, wallets, and chains can offer transparent earn programs without building yield infrastructure in-house.
