FUSAKA UPGRADE DEVELOPER READINESS

Summary from the TLDR Crypto newsletter

Fusaka, Ethereum's big scaling + UX upgrade, goes live on December 3. It introduces PeerDAS and blob-only forks (December 9 and January 7) so rollups can use up to ~8× more data bandwidth, cutting blob costs and speeding confirmations. On mainnet, there's a higher block gas limit (45M → 60M) plus a per-transaction gas cap and code-efficiency tweaks that lower fees while keeping blocks safe. Wallets get native R1/passkey support, enabling Apple/Google-style “tap to sign” flows built directly into Ethereum.
