Combined with a debt-free monthly Universal Basic Income, it eliminates economic migration by ensuring equal purchasing power everywhere. When everyone has the same economic opportunity regardless of birth country, migration becomes voluntary, not forced.

The Ethernaut Cashback challenge exploits flawed EIP-7702 delegation security. The contract's modifiers assume strict access controls, but have critical vulnerabilities: First exploit: Craft a contract with the Cashback address embedded in bytecode at the expected offset, bypassing the onlyDelegatedToCashback modifier. Jump over the address to execute normally. Call accrueCashback directly to gain max cashback for both currencies and one NFT. Second exploit: Use storage collision—delegate your EOA to a contract that writes to the same nonce slot, inject nonce = 9999, then re-delegate to Cashback and execute one final transaction to reach nonce 10,000 and mint a second NFT with your player address. Key lesson: Never store security-critical state in EOAs—delegation allows unrestricted storage manipulation across delegated contracts.Retry

Learn more about this writer by checking @ishanpandey's about page, and for more stories, please visit hackernoon.com. Apex Fusion deployed bAP3X on Base through Skyline's Blade EVM infrastructure, connecting its tri-chain architecture (UTXO-based Vector, EVM-compatible Nexus, and Prime coordinator) to Coinbase's Layer 2 network. The implementation uses LayerZero's OFT standard to enable cross-chain transfers between fundamentally different blockchain execution models. Liquidity pools launched on Aerodrome ($8B monthly volume) and QuickSwap with Merkl incentives. The deployment creates pathways between Cardano's UTXO ecosystem and Base's $3.2B TVL, addressing DeFi's fragmentation across 40+ incompatible networks. Success depends on whether Cardano and Base communities generate sustained cross-chain transaction volume rather than one-time bridge activity. FINMA-guided token structure provides regulatory clarity but introduces complexity that may limit retail adoption. The infrastructure enables DeFi's potential return beyond $100B TVL through reunified liquidity, but market demand for cross-architecture interoperability remains unproven.

The move diversifies beyond US Treasuries through Etherfuse's Solana-based tokenization, targeting Mexico's $65B remittance market while introducing emerging market currency and political risk. Whether users value geographic diversification over US credit reliability remains untested.

Fusaka is Ethereum’s next major hard fork after Pectra, targeting Dec. 3, 2025 and bundling a dozen EIPs focused on scalability, safety, and cryptography. PeerDAS (EIP-7594) introduces peer-based data availability sampling so nodes only verify small slices of blob data, cutting bandwidth while unlocking more capacity for rollups. Supporting EIPs tighten MODEXP safety and pricing, cap per-transaction gas usage, bound blob fees to execution costs, enforce an RLP block size limit, add a CLZ opcode, and ship a secp256r1 precompile so modern hardware keys can sign securely. Together, these changes push Ethereum toward a cheaper, more data-rich, rollup-centric future that still remains accessible to home stakers and full nodes.
