SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

KyberSwap swap operations can fail at API route fetch/build, or during on-chain execution. This guide provides a structured debugging workflow to identify error phases, apply targeted remedies, and recover trading flows.

Core Features & Use Cases

  • Error categorization: API errors, pre-transaction errors, and on-chain errors with concrete guidance.
  • Workflow-driven fixes: Step-by-step procedures to diagnose, retry, and fix failures across RFQ/PMM sources and multiple chains.
  • Best practices: Route freshness, slippage management, and robust retry patterns to improve success rates.
  • Use Case: A developer encounters a route-not-found (4008) or gas-estimation failure (4227) and follows the guide to fetch a fresh route, adjust filters, or increase slippage.

Quick Start

Inspect the latest error, identify its category, and apply the recommended fixes in the order listed above.

FAQPage Schema
How do I debug KyberSwap API route errors when swapping tokens?▼

To debug KyberSwap API route errors, identify whether the failure occurred during route fetch or on-chain execution, then apply targeted remedies like fetching a fresh route or adjusting slippage to recover the trading flow.

What causes gas-estimation failures on the KyberSwap Aggregator API?▼

Gas-estimation failures on the KyberSwap Aggregator API occur during pre-transaction checks when the route is stale or parameters are misconfigured. Fetching a fresh route or adjusting filters resolves the estimation error.

How do I fix on-chain reverts when executing a token swap via KyberSwap?▼

Fix KyberSwap on-chain reverts by following the structured debugging workflow to identify the error phase, manage slippage settings, and apply robust retry patterns for failed RFQ or PMM transactions.

What is the best way to handle a route-not-found error on KyberSwap?▼

The best way to handle a KyberSwap route-not-found error is to fetch a fresh route, adjust your token filters, or increase slippage tolerance according to the recommended remedy workflow.

Does the KyberSwap error handling guide cover RFQ sources and multiple chains?▼

Yes, the KyberSwap error handling guide covers RFQ and PMM sources across multiple chains, providing structured procedures to diagnose pre-transaction checks and on-chain execution failures.
