Spark Savings is now native inside @Rabby_io ⚡️ ️ This is more than an integration. It’s a glimpse of where wallets are going: from holding assets → helping users put idle capital to work safely, instantly, and without leaving the wallet. With Spark x Rabby, users can now earn on USDS, USDC, USDT, and ETH directly inside Rabby. No bridges. No extra steps. No fragmented UX. For Rabby users, this means idle assets can now earn directly from the wallet they already trust. This trust is now reinforced by the Spark Savings Risk Framework, with its risk absorption layers which means SAFETY FIRST INSTANT REDEMPTION.

One of the hardest problems in credit markets is balancing liquidity and deployment. Hold too much capital in reserve and returns suffer. Deploy too much capital and liquidity suffers. Spark's Liquidity Layer holds $1.11B of USDT across two roles. $571M sits as plain USDT in the ALM proxy. That's the idle liquidity buffer. Most withdrawals clear instantly against it. Larger exits go through a request flow. $545M is deployed into SparkLend's USDT pool as spUSDT, earning the benchmark rate. Same asset, two different jobs. The split is what lets Spark Savings USDT offer real liquidity depth and a competitive return at the same time. Deposit USDT: app.spark.fi/savings/mainnet…

While Mythos is changing the security threat model in some ways, I am not particularly concerned about exploits being found in blue-chip smart contracts. If the code base is small and important enough (most SC code is), then traditional methods are sufficient to achieve high confidence in security. What's changing is the cost of searching for exploits in large codebases. These bugs were always there, but we are compressing the time to discover them. This is largely what is driving the recent infrastructure compromises affecting everyone. With smart contracts, this can be protected against using rate limits and timelocks, limiting the damage that can be done if an off-chain system is hacked. Overall, this is a period of understandable apprehension, but I'm confident that by following best practises we can make it to the other side stronger than before.

Most lending markets end up dominated by a single trade. BTC holders borrowing stablecoins. ETH loopers leveraging exposure. Stablecoin borrowers chasing liquidity. This week on SparkLend, all three were active at the same time: → ~$44M cbBTC supplied, $17M USDS borrowed → ~$34M WETH supplied, $25M USDS borrowed → ~$16M wstETH supplied, $15M WETH borrowed Different collateral. Different strategies. Different market views. More than $120M in combined collateral activity moved through the market, yet rates remained stable and no single cohort crowded out another. That's what market depth actually looks like. Not just TVL. A market that can support multiple large borrower profiles simultaneously without breaking price efficiency.

Spark closed May with $6.4B in Savings TVL, $3.6B in SparkLend TVL, and $2.6B deployed through the Spark Liquidity Layer. Behind those numbers: four new ATHs, new integrations with @Gate and @BinanceWallet, and wBTC supply limits expanded 10x. Here's the month in full. ⚡️

Relook: Spark Prime is CeDeFi margin lending for institutional borrowers. Most institutional strategies do not operate in one venue. Collateral sits with custodians, execution moves across exchanges, and exposure runs through DeFi protocols and traditional market infrastructure. Spark Prime extends overcollateralized lending across these environments. Powered by @ArkisXYZ margin technology, it operates within a defined risk framework, with positions visible in real time. The result is institutional financing infrastructure built around the full position, not one venue. Read more about Spark Prime👇 paragraph.com/@spark-11/spar…
