burner-wallet

Build and test the burner-wallet monorepo. Runs signer (Java ME / Ant) and companion (Rust / Cargo) test suites. Use after making code changes to verify correctness, or when the user asks to run tests, build, or check the project.

Create a git commit following this project's Conventional Commits format with DCO sign-off. Use when the user asks to commit changes or when code changes are ready to be committed.

Verify that the Java ME signer and Rust companion produce identical outputs for the same cryptographic inputs. Use after modifying any BIP39/32/44/84/173 code in either signer/ or companion/core/, or when updating protocol/vectors/.

Security-focused review for cryptographic code in signer/ and companion/core/. Validates BIP standard compliance, checks for timing side-channels, verifies test vector coverage, and ensures cross-implementation consistency. Use when modifying files in signer/src/org/burnerwallet/core/, signer/src/org/burnerwallet/chains/, or companion/core/src/.

Enforces Java ME constraints when writing code in signer/. Prevents Java 5+ language features, validates CLDC 1.1 and MIDP 2.0 API usage, and monitors JAR size. Use whenever editing or creating Java files under signer/src/ or signer/test/.

Implementation guide for BIP174 PSBT (Partially Signed Bitcoin Transactions) on the Java ME signer. Reference for M1c milestone. Use when working on PSBT parsing, signing, or transaction construction in signer/src/org/burnerwallet/transport/ or signer/src/org/burnerwallet/chains/bitcoin/.

Monitor and optimize the signer JAR size to stay under the 1 MB budget. Use when adding new classes or dependencies to signer/, or when the user is concerned about JAR size.
