evstack

Use the Evolve execution debugger for trace recording, replay, and time-travel debugging. Use when debugging failing tests, recording execution traces, stepping through state changes, or analyzing execution flow.

Write modules for the Evolve SDK using AccountCode trait and account_impl macro. Use when creating modules, writing account code, using AccountState, storage prefixes, or developing new blockchain modules.

Create custom Evolve blockchain nodes by composing storage, STF, mempool, RPC, and gRPC components. Use when the user wants to create a new node binary, build a custom chain, compose node components, or asks about evd/testapp architecture.

Write property-based tests for Evolve SDK using proptest. Use when writing property tests, invariant testing, fuzz testing, test generators, or finding edge cases.

Use the Evolve deterministic simulator for testing with controlled time, storage, and randomness. Use when creating simulations, seed-based testing, fault injection, stress testing, or deterministic test reproduction.

Overview of Evolve SDK testing infrastructure including TestApp, SimTestApp, MockEnv, and transaction generators. Use when writing tests, setting up test harnesses, using test infrastructure, or choosing between testing approaches.

Analyze State Transition Function implementations for correctness, threading issues, non-determinism, and simplification opportunities. Use when analyzing STF code, checking threading model, finding non-determinism sources, or reviewing execution layer.

Explains ev-node architecture, components, and internal workings. Use when the user asks how ev-node works, wants to understand the block package, DA layer, sequencing, namespaces, or needs architecture explanations. Covers block production, syncing, DA submission, forced inclusion, single vs based sequencer, and censorship resistance.
