Add tests for the consolidate_deposits function covering: - Early return when no funds to consolidate - Early return when task already active (guard) - Early return when fetching blockhash fails - Single consolidation request with event assertions - Multiple consolidation batches (11 accounts → 2 batches) Also adds canister_self() to CanisterRuntime trait to enable mocking in tests, and extracts MAX_TRANSFERS_PER_CONSOLIDATION constant for test visibility. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Record `ConsolidatedDeposits` and `SubmittedTransaction` events before calling `submit_transaction` to ensure they persist for resubmission even if the RPC call fails. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Add timer task that resubmits all pending transactions every 60 seconds with a fresh blockhash. Uses ResubmittedTransaction event to track the signature change and updated slot. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Add tests for the resubmit_transactions function covering: - Early return when no transactions to resubmit - Early return when task already active (guard) - Early return when fetching current slot fails - No resubmission when transaction not expired - Single expired transaction resubmission with event assertions - Event recorded even when submission fails 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Add a dropping proxy that can simulate network failures where `sendTransaction` RPC calls appear to succeed but transactions never land on-chain. This is useful for testing the resubmission logic. The new test: 1. Starts a proxy that drops the first sendTransaction request 2. Creates deposits and triggers consolidation (transaction dropped) 3. Waits for slots to advance past MAX_BLOCKHASH_AGE 4. Triggers resubmission timer 5. Verifies funds are consolidated after resubmission 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Add an integration test that verifies deposit consolidation and transaction resubmission against a local Solana validator. The test deposits funds, triggers consolidation, waits for the blockhash to expire, and verifies the minter resubmits the transaction with a fresh blockhash.
To simulate a dropped transaction, the test uses a
JsonRpcReverseProxy— a lightweightaxummiddleware that sits between the minter and the Solana validator. It can be configured to block specific JSON-RPC methods (e.g.sendTransaction) by returning an error instead of forwarding the request. This lets us test the resubmission flow without needing to actually drop network packets: the minter believes the transaction was submitted (and records aSubmittedTransactionevent), but the transaction never reaches the validator.The proxy is integrated into
SetupBuilderviawith_json_rpc_proxy(url, port), and its blocklist can be toggled at any point during the test withsetup.json_rpc_proxy().block(...)andsetup.json_rpc_proxy().clear_blocklist().
