Stylus Upgrades Contents - Stylus Upgrade Model - Proxy Patterns - Access Control - Upgrade Safety Stylus Upgrade Model Stylus contracts run on Arbitrum as WebAssembly (WASM) programs alongside the EVM. They share the same state trie, storage model, and account system as Solidity contracts. Because of this, EVM proxy patterns work identically for Stylus — a Solidity proxy can delegate to a Stylus implementation and vice versa. | | Stylus | Solidity | |---|---|---| | Proxy mechanism | Same — to implementation contract | to implementation contract | | Storage layout | fields map to the same EVM…
