Debug Tracing Overview

Requirements

The examples in this guide call the debug JSON-RPC endpoints directly with curl — no SDK or additional libraries are required. Optionally install jq to pretty-print the JSON responses:

# macOS
brew install jq

# Debian/Ubuntu
sudo apt-get install jq

Debug tracing is your primary tool for understanding EVM transaction execution on Sei. This comprehensive system allows you to analyze transaction flow, optimize gas usage, debug smart contract interactions, and troubleshoot production issues.

What You Can Trace

Transaction Execution

Step-by-step opcode execution
Contract call hierarchy
Gas consumption breakdown
State changes and storage access

Contract Interactions

Cross-contract calls and returns
Event emission analysis
Precompile usage tracking
External library calls

Performance Analysis

Gas optimization opportunities
Bottleneck identification
Cache hit/miss patterns
State access efficiency

Security Analysis

Suspicious operation detection
Reentrancy pattern analysis
Access control verification
Vulnerability scanning

Available Tracing Methods

Method	Purpose	Use Case
`debug_traceTransaction`	Trace specific transaction	Debugging failed transactions
`debug_traceBlockByNumber`	Trace entire block	Block-level analysis
`debug_traceCall`	Simulate and trace	Testing before execution
`debug_traceStateAccess`	State access patterns	Performance optimization
`debug_traceTransactionProfile`	Trace plus timing/store-access profiling	Latency breakdown and DB-access analysis

Transaction Analysis Example

Debugging Failed Transactions

Steps to analyze and resolve transaction failures:

Step 1: Identify the Problem

# Get transaction receipt
FAILED_TX="0xb2a6f4f7f37d8df728968126c05d1a8b0391003cf375ed5abb1b5e02fe66c717"

curl -X POST -H "Content-Type: application/json" \
  --data '{
    "jsonrpc": "2.0",
    "method": "eth_getTransactionReceipt",
    "params": ["'$FAILED_TX'"],
    "id": 1
  }' \
  https://evm-rpc.sei-apis.com

Step 2: Trace the Execution

# Trace to see where it failed
curl -X POST -H "Content-Type: application/json" \
  --data '{
    "jsonrpc": "2.0",
    "method": "debug_traceTransaction",
    "params": [

Common Debugging Scenarios

Transaction Reverted

Problem: Transaction failed with revert Solution: Use callTracer to find the exact revert reason

Out of Gas

Problem: Transaction ran out of gas Solution: Use gas analysis tracer to optimize gas usage

Unexpected Behavior

Problem: Transaction succeeded but wrong result Solution: Use opcode tracer for step-by-step analysis

Slow Performance

Problem: Transaction uses too much gas Solution: Use state access tracer to find inefficiencies

Quick Reference

Essential Commands

# Trace transaction
debug_traceTransaction(hash, {tracer: "callTracer"})

# Trace block
debug_traceBlockByNumber("latest", {tracer: "callTracer"})

# Simulate call
debug_traceCall(tx, "latest", {tracer: "callTracer"})

# State access
debug_traceStateAccess(hash)

Common Tracers

callTracer: Contract call hierarchy
opcodeTracer: Opcode-level execution
Custom JS: Custom analysis logic

Pre-Baked Trace Cache

RPC nodes can optionally pre-compute and cache debug_trace* results in the background so that trace requests are served from a local on-disk cache instead of re-executing the block live on every call. This is an opt-in feature configured through new [evm] fields in app.toml and is recommended for RPC nodes only. When enabled, a background worker re-executes each committed block with the configured tracers and stores the results in a Pebble database at <home>/data/trace_db. The following methods serve from this cache on hit, and otherwise fall through to live re-execution:

debug_traceTransaction
debug_traceBlockByNumber and debug_traceBlockByHash

When the cache is used

A request is only served from cache when trace baking is enabled and the request uses a bakeable tracer configuration:

The tracer is one of callTracer, prestateTracer, or flatCallTracer.
No custom tracerConfig is supplied. A per-call tracerConfig (for example {"withLog": true}) is not part of the cache key, so any custom tracer config makes the request un-bakeable and it falls through to live re-execution.

Requests that use the struct logger (no tracer), a JavaScript tracer, or any other named tracer are always executed live.

Configuration

Trace baking is controlled by these [evm] fields in app.toml:

Field	Default	Description
`trace_bake_enabled`	`false`	Enables the background trace-baking worker that caches results at `<home>/data/trace_db`. RPC nodes only.
`trace_bake_workers`	`1`	Number of re-execution worker goroutines.
`trace_bake_queue_size`	`4096`	Bounds the in-flight height queue. Heights are dropped when the queue is full so consensus never blocks; dropped blocks fall through to live re-execution.
`trace_bake_tracers`	`["callTracer"]`	Which tracers to bake per block. Eligible values: `callTracer`, `prestateTracer`, `flatCallTracer`.
`trace_bake_window_blocks`	`0`	Rolling prune window: blocks older than `(latest - window)` are pruned. `0` disables pruning, so the cache grows forever.
`trace_bake_use_snapshot`	`false`	Uses in-memory memiavl snapshots as the state backend for trace baking when the store backend supports snapshots.
`trace_bake_snapshot_window`	`64`	Number of recent memiavl snapshots to retain for trace baking.

Enabling trace baking adds a persistent on-disk store at <home>/data/trace_db and increases disk usage. The store’s write-ahead log is flushed when the node shuts down cleanly.

`*ExcludeTraceFail` filtering semantics

The *ExcludeTraceFail endpoints (sei_getTransactionReceiptExcludeTraceFail, sei_getBlockByNumberExcludeTraceFail, and sei_getBlockByHashExcludeTraceFail) filter out transactions whose trace would be empty or meaningless — specifically, transactions that were included in a block but never actually executed in the VM. These are deprecated legacy endpoints and are disabled by default: each method must be enabled through enabled_legacy_sei_apis in the [evm] section of app.toml. The filter keys off the receipt shape — any receipt with EffectiveGasPrice == 0 && GasUsed == 0, plus chain-generated synthetics — which excludes three classes:

Ante-deferred stub transactions: txs that passed the nonce check but failed a later ante step (for example insufficient funds or insufficient fee) and so never reached the VM. The chain writes a stub receipt for these with both fields unset.
Nonce-bumping state-transition failures: txs that fail inside go-ethereum’s Execute() before any opcode runs (for example an EIP-7623 floor-data-gas shortfall). Their synthetic EndBlock receipt carries the same EffectiveGasPrice == 0 && GasUsed == 0 shape, so it is filtered identically.
Chain-generated synthetic transactions: txs with the internal ShellEVMTxType, which have no real EVM execution.

Everything that executed opcodes in the VM is included, even if it failed. Reverted and out-of-gas (OOG) transactions have Status == 0 but GasUsed > 0 (intrinsic gas at minimum) and, on chains with a positive minimum gas price, EffectiveGasPrice > 0, and produce a real trace (the REVERT or OOG condition simply appears inside that trace), so they are returned rather than filtered out.

This filter applies to the block endpoints (sei_getBlockByNumberExcludeTraceFail and sei_getBlockByHashExcludeTraceFail, plus their sei2_ equivalents) and the receipt endpoint (sei_getTransactionReceiptExcludeTraceFail): all of them drop these ante-deferred stub transactions. The former sei_traceBlockByNumberExcludeTraceFail and sei_traceBlockByHashExcludeTraceFail endpoints were removed in v6.6.0 — use debug_traceBlockByNumber or debug_traceBlockByHash for block tracing. The regular eth_getBlockBy* endpoints continue to include them, so a tx that appears in a normal block response may be absent from the *ExcludeTraceFail variant. The filter checks the underlying receipt shape (EffectiveGasPrice and GasUsed) rather than any tracer-reported error field.
