Glamsterdam is not just a generic protocol-level upgrade: it changes what app developers can build and what can break. This talk focuses on the application-layer impact. We cover the 64 KiB contract size limit (up from 24 KiB) and what it means for libraries and diamond proxies, deeper stack access (DUPN/SWAPN/EXCHANGE) that removes most "stack too deep" errors, EIP-7708 logs for every ETH transfer that make ETH indexable via eth_getLogs, the new SLOTNUM opcode, gas repricing (state-creation costs, cheaper no-value calls), a higher gas limit floor, and the CREATE2 factory becoming required chain state. For each change: before, after, and the catches (e.g. higher deploy costs, log edge cases). Attendees get a concrete checklist for contracts, indexers and tooling.
