Introducing Arcana Wallet with Chain Abstraction!🌟 Beta is now live on Chrome Store! Get started👉 You can now unify your USDC, USDT, and ETH balances across Ethereum, Base, Polygon, Arbitrum, and Optimism— and spend it in one click, without bridging. 💡Beyond the core benefits of #ChainAbstraction like unified balances, auto-fund gas fees with stablecoins, and near-instant multi-chain transactions, $XAR Chain Abstraction Protocol does three things extremely well: 🔹EOA Wallet-Based Orchestration: Bring your existing wallet address without locking up funds or depositing into a new account—full self-custody of assets. 🔹Gas Efficiency: Upto 5X lower gas fees compared to smart contract-based chain abstraction 🔹Universal Addresses: Arcana does not create app-specific wallets that require users to deposit tokens. This means your assets remain in a single wallet, accessible across apps —even on apps that do not support chain abstraction. Try spending your unified balances on apps like Uniswap, Aave, Polymarket, Hyperliquid, and Jumper🌐 Arcana Wallet is deployed on the Chain Abstraction Testnet. The Testnet launch marks an important milestone in bringing a chainless experience to users across ecosystems, as we get closer to the launch of Mainnet✨ Arcana’s Chain Abstraction Protocol (powered by $XAR) is the cornerstone of Arcana Wallet's capabilities, driving a new era of multichain usability. Developers will soon be able to leverage our Chain Abstraction SDK, empowering them to build chainless user experiences.

We begin by showing the public balances of the sender and the authority, then we open a raw storage read for the authority’s account. That storage call is System. Account for the authority’s AccountId; it returns the canonical AccountInfo record (SCALE-encoded). The key field is which is the on-chain public balance you also see in Polkadot.js Apps. Whatever appears there is the ledger’s truth for spendable funds. Next, we perform a transfer with zero fee. After it finalizes, we show that only the sender’s public balance changed, the authority’s balance is identical, and the same System. Account read returns the exact same AccountInfo. This confirms no fee was credited publicly. We then repeat the test with a transfer that includes a fee of 100 base units. Once the block finalizes, the authority’s increases by exactly 100. Reading System. Account again makes the change explicit: the storage value itself changed, proving the fee was deposited to the authority’s public balance. This storage query matters because it bypasses any off-chain interpretation: it is a direct read of the canonical state. If System. Account’s free balance changes, the chain has credited funds. Finally, a note on design choices. In this demo the fee is paid publicly, which maximizes auditability and operational simplicity, anyone can verify validator revenue. An alternative is to pay validators as private notes, keeping their income hidden. That improves privacy but adds protocol and operational complexity (note issuance, key handling, and proofs) and reduces straightforward, public auditability. In short: public fees emphasize security and transparency; private fees emphasize privacy but require stronger safeguards and more complex operations.

❤️ Introducing Raspberry Celestia's first public testnet built On 🟠 Gelato RaaS Celestia helps to reduce the DA cost by up to 99% vs. Ethereum. With Raspberry, you can finally test it out. Gelato/Celestia Raspberry is the first public good Celestia testnet with all the necessary infrastructure for developers to build whatever → Production-ready implementation of Celestia Modular DA → All of the necessary infra to build whatever → No real-world value at risk Raspberry is FREE FOR EVERYONE. Raspberry is a public good initiative by Gelato and 10+ partners to accelerate the modular expansion by lowering the barriers for developers to build and test whatever in a production-ready environment. Like Sepolia to Ethereum, Raspberry is the playground to build whatever on Celestia. → Framework: OP Stack → DA Layer: Celestia → Settlement Layer: Sepolia → Cost per transaction: $ 0.002 → Throughput: ~2000–4000 tps Raspberry is MADE FOR BUILDERS. Raspberry includes all Gelaton Web3 Services and all essential 3rd party tooling & infrastructure. Gelato Web3 Services: → Functions - smart contract automation → Relay - gasless transaction → VRF - verifiable onchain randomness → Bridge UI - bridge testnet Eth 8+ natively integrated tooling & infra: → Goldsky ☀️ - read, edit, and sync fresh chain data → dRPC // AI-powered RPC Infrastructure - access reliable & globally distributed nodes → @blockscoutcom - access essential on-chain data → thirdweb - onboard anyone with flexible sign-in options → ZeroDev - create smart wallets for your users → Safe.eth - use the most secure smart wallet infrastructure → DIA Oracles - source data from on and off-chain platforms → Tenderly - build, test, monitor, and operate smart contracts Start building on 🟠 Raspberry testnet today ↓ Hack on Raspberry at CelestiaOrg's #1st global online Hackathon with $100k+ prize pool ↓ Build whatever
