Caldera.xyz builds customizable blockchain rollups on top of Ethereum and Polygon to boost throughput and cut costs. They provide a no-code platform to build, launch, and manage rollups, and the rollups are EVM-compatible so existing Solidity contracts work. Revenue comes from transaction fees, bridge fees, and MEV, with options to pay gas in native tokens or eliminate gas fees. Differentiators include high configurability, a code-free interface, and native gas-economy customization, with the goal of enabling scalable, interoperable, easy-to-deploy blockchain apps.

Arbitrum show 49% transaction boom and major WETH/WBTC inflows. * Arbitrum saw a major activity surge, with transactions up 49%, DEX volume up 18%, and strong WETH/WBTC inflows. * Ecosystem accelerated, with big milestones from Robinhood, Hyperliquid, Ostium Labs, Caldera, Footium, and more. * ARB price showed a mild uptick, rising 2.5% in 24h as investors watch for a breakout above the $0.23 resistance level. Arbitrum just had one of the best weeks ever. Activity on the network has gone up a lot, and there have been a number of big wins for the ecosystem. In the last week, Arbitrum saw a 49% increase in transactions, an 18% increase in DEX volume, and a lot of WETH and WBTC coming in, which means that more money is moving onto the chain. The most recent data from Nansen shows that even though the number of active users went down during the week, Arbitrum's transaction count and on-chain liquidity kept going up. This suggests that the users who are still active are doing more and adding more value to the network. Strong chain performance. * Transactions: 21.9M in 7 days (+49%), the fastest growth among major Layer 2 networks. * Active Users: 1.07M (-39%), showing fewer but more engaged users. * Gas Fees: $314.7K for the week, ranking 7th across chains. * DEX Volume: $3.5B (+18%), showing strong trading activity. The bullish indicators like rising transactions, rising DEX volume, and significant inflows of WETH and WBTC, are often seen as a sign of capital preparing to deploy into DeFi. Stablecoin activity also expanded, with USDAI, sUSDAI, and other assets flowing into the ecosystem, another indicator that users are preparing to transact, trade, and stack. Other ecosystem wins. Beyond metrics, the past week was packed with major milestones from builders across Arbitrum: * Robinhood App crossed 1,000+ tokenized stocks, ETFs, and commodities on Arbitrum One, with over $10M in tokenized value. European users can already access these assets fully on-chain. * Arbitrum was featured in Etherealize's "Ethereum Layer 2 Landscape" report, where it led all L2s with $17.5B in TVL. * Ostium Labs raised $20 million to continue developing its "perpification of everything" platform. * Caldera launched its Onchain Expansion Program, giving ERA holders access to deep liquidity on Arbitrum One. * A massive Arbitrum Everywhere bounty was claimed after a user photographed Arbitrum branding above the Arctic Circle, a fun community moment. * Hinkal Protocol went live, adding confidential payments to Arbitrum. * Footium partnered with Manchester United legend Dimitar Berbatov, bringing mainstream sports visibility to the chain. * Rhea Finance joined Arbitrum, enabling multi-chain lending. * Warden Protocol launched AI-enabled swaps and more for Arbitrum users. * Anoma added support for Arbitrum, offering one-click intent-based UX and enhanced privacy. It was a week that not only showed strong metrics but also how fast developers continue to build on Arbitrum. ARB price action. Arbitrum's token, ARB, saw a mild price increase compared to the strong on-chain activity. ARB rose 2.5% in the past 24 hours, contributing to an 8% weekly climb. Since Hyperliquid has enabled direct native USDC deposits, it has reduced fees and improved user experience. This makes onboarding smoother and strengthens Arbitrum's position. Analysts said that ARB might not be undervalued. The token dropped 70% in the last quarter, but TVL is still going up. Stablecoin liquidity went over $4 billion, which shows that there is a lot of demand from users for transactions and yield opportunities. Short-term momentum is on the side of the bulls, but a long-term recovery needs to break through $0.234 (61.8% Fib). The RSI-14 at 39.41, which is neutral, and the MACD bullish crossover both support this idea. ARB is now close to support at $0.21, and a close above $0.23 could mean that the trend has changed. Arbitrum's 7-day performance shows that despite fewer active users, activity per user is rising fast, big players are building, liquidity is flowing in, and the ecosystem continues to strengthen. With major inflows, record transaction growth, and expanding developer momentum, Arbitrum is positioning itself as one of the strongest Layer 2s heading into the next cycle.
