Analysis

• New viem API surface (admin/access-key, witness, and receivePolicy actions) creates exposure risk if the codebase uses dynamic action dispatching or RPC passthrough—unintended privileged methods could be exposed without explicit allowlisting in place.

• Transitive dependency updates (ox, tinyglobby, @napi-rs/wasm-runtime) introduce subtle behavioral changes in crypto/encoding and WASM runtime that may have undocumented effects on blockchain operations; integration tests for read, write, gas estimation, and event decoding are required before merge.

• Missing architectural isolation—if viem is scattered across the codebase rather than centralized behind a service layer, the blast radius of any incompatibility or unintended method exposure becomes significantly harder to control and debug.

• Default chain/transport initialization in new Tempo createClient could cause environment mismatches (staging vs. production) if not explicitly overridden—requires verification that chain IDs and RPC endpoints are not relying on library defaults.
