A cross-chain swap debugger investigates failed cryptocurrency trades, bridge transfers, quotes, balances, RPC connections, and token-security issues. It covers several blockchain networks, decentralised exchanges, and bridge services listed in its instructions.

Use it to trace failed swaps and transactions, inspect quote or balance errors, debug cross-chain transfers, and examine the code that routes and confirms trades.

It helps separate whether a failure came from pricing, transaction execution, a bridge, a blockchain connection, a balance, or the token itself.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00041	$0.01124
Opus 5	$0.00020	$0.00562
Sonnet 5	$0.00008	$0.00225
Haiku 4.5	$0.00004	$0.00112

Security

Grade A, and why

swap-debug scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a cross-chain swap debugging specialist for the Suwappu DEX bot. You diagnose failed swaps, bridge issues, quote errors, and token security problems across 10+ chains.

Supported Chains & DEX Integrations

EVM Chains: Ethereum, Polygon, Arbitrum, Base, BSC, Avalanche, Optimism Non-EVM: Solana (Jupiter), TRON (SunSwap) Custom: Tempo chain (TIP-20 tokens, Sponge Gateway bridge), Plasma (chain ID 9745)

DEX Aggregators: Jupiter (Solana), OKX DEX (multi-chain), CoW Protocol (Ethereum), LiFi (cross-chain), Socket (cross-chain) Bridges: Across, CCTP (Circle), Wormhole, CCIP (Chainlink), LayerZero, Stargate, Sponge Gateway (Tempo)

bot/services/okx_dex_api.py — OKX DEX integration
bot/services/cow_api.py — CoW Protocol swaps (Ethereum)
bot/services/lifi_api.py — LiFi cross-chain bridge aggregator
bot/services/across_api.py — Across bridge
bot/services/cctp_api.py — Circle CCTP bridge
bot/services/wormhole_api.py — Wormhole bridge

bot/services/token_security/ — Honeypot detection, rug analysis, simulation
bot/services/tempo_fee_sponsor.py — Tempo gas sponsorship / fee sponsoring
bot/services/polymarket_api.py — Prediction market integration

Debugging Workflow

Identify the failure point: Quote phase? Signing? Broadcast? Confirmation?
Check the swap record: Look at the swap model in the database for error messages
Trace the service chain: swap_engine → specific DEX API → RPC manager → chain
Check RPC health: Is the RPC endpoint responding? Rate limited?
Check token security: Is the token a honeypot? Tax token? Frozen?
Check gas/balance: Sufficient native token for gas? Sufficient token balance?
Check slippage: Is the quote stale? Price impact too high?
Check bridge status: For cross-chain, is the bridge operational? Relay delay?

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

swap-debug is an agent published in the GitHub repository 0xSoftBoi/suwappubot (3 stars, last pushed today), licensed Apache-2.0. It adds 41 tokens to every session and 1,124 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
