  • MEV Defense: Limits of Simulation, Slippage Controls, and Private Submission

    한국어로 읽기 TECH INSIGHT / EXPLAINED A reverted swap or disappointing fill is not enough evidence to diagnose MEV. Separate state changes, slippage limits, balances, allowances, nonces, and gas problems before choosing a defense.

  • Seven Trading Bot Checks: Timing, Costs and Unknown Orders

    한국어로 읽기 TECH INSIGHT / EXPLAINED A trading bot can lose money because of its strategy, implementation, costs or market conditions. These seven checks address implementation and evaluation errors; passing them does not establish a profitable strategy.

  • Public Crypto Candle Data: Pagination, Gaps and Closed-Bar Archives

    한국어로 읽기 TECH INSIGHT / EXPLAINED Public candle APIs are useful for learning and reproducible research. The collection task is more than downloading rows: record the source, page boundaries, timezone, missing intervals and whether the latest candle has closed.

  • Evaluating Crypto Bot Profits: Fees, Open Inventory and Evidence

    한국어로 읽기 TECH INSIGHT / EXPLAINED A bot-profit claim needs records: the test period, deposits and withdrawals, trades, fees and open inventory. Without them, a smooth backtest curve cannot establish realized account performance.

  • Upbit Python API: Quotes, Correct Signing and Order Validation

    한국어로 읽기 TECH INSIGHT / EXPLAINED Build the integration in observable stages: public quote, authenticated read, locally validated order payload, then a documented order test. A successful HTTP response and a completed trade are different milestones.

  • Event Logs and Pool Reserves: Decode Safely, Track Sync and Reorgs

    한국어로 읽기 TECH INSIGHT / EXPLAINED A correctly decoded log is not automatically a correct pool state. First identify the contract and ABI; then decide whether the event describes a trade or a complete reserve update.

  • EIP-1559 Gas Costs: Separate the Estimate, Fee Cap and Receipt

    한국어로 읽기 TECH INSIGHT / EXPLAINED Separate three quantities: the gas limit you authorize, the gas actually used, and the effective price paid per unit. A fee cap is a budget ceiling, not the final bill.

  • Triangular Arbitrage: Calculate the Fee Break-Even Before the Trade

    한국어로 읽기 TECH INSIGHT / EXPLAINED A three-token cycle is profitable only if its executable output returns more of the starting token after every cost. Multiplying three displayed prices is a screening calculation, not an executable quote.

  • Filtering Risky Tokens: Fee-on-Transfer Detection and Rug Pull Defense

    한국어로 읽기 TECH INSIGHT / EXPLAINED Token screening is evidence gathering, not proof of safety. A token can implement an ERC-20-shaped interface while applying transfer fees, restrictions or upgradeable behavior that a simple pool quote does not capture.

  • DEX Quoting: V2 Constant Product vs. V3 Concentrated Liquidity

    한국어로 읽기 TECH INSIGHT / EXPLAINED A swap quote is a result for a particular amount, pool state and fee rule. V2 and V3 can both be modeled precisely, but they need different state and arithmetic. Keep token quantities in integer base units until presentation.

  • Multi-RPC Rotation and Failover for On-Chain Bots

    한국어로 읽기 TECH INSIGHT / EXPLAINED RPC failover is useful only if the replacement node serves the right chain and compatible state. A fast connection or a larger reported block number alone is not proof of a trustworthy quote.

  • DEX Scanner Adapters: Quotes, Capabilities and Execution

    한국어로 읽기 TECH INSIGHT / EXPLAINED The adapter pattern lets one scanner reason about different DEX protocols without pretending that their quote and execution mechanics are identical. Scaling to dozens of venues is an architectural target here, not a verified claim that 24 production integrations were operated.

  • The Reality of Flash Loan Arbitrage Bots

    한국어로 읽기 TECH INSIGHT / EXPLAINED Flash loans allow an uncollateralized borrowing path that must satisfy the lender’s same-transaction repayment rules. Atomic rollback protects a particular on-chain state transition; it does not make an arbitrage attempt free of economic loss.

  • Intro to Crypto Arbitrage

    한국어로 읽기 TECH INSIGHT / EXPLAINED Crypto arbitrage starts with executable prices and ends with reconciled inventory. A difference between two last-trade prices is only a clue: the amount available, trading fees and settlement path determine whether a trade can be completed.

  • Building a Grid Trading Bot on Bithumb

    한국어로 읽기 TECH INSIGHT / EXPLAINED A grid bot places limit orders at predefined price levels and manages the inventory created when they fill. Oscillation can create completed buy–sell pairs; it does not turn every price movement into profit. This design note uses hypothetical numbers, not an account performance claim.

  • Binance Futures Bot Architecture: Notional Sizing and Protective Order State

    한국어로 읽기 SYSTEM DESIGN / FUTURES A futures bot needs a consistent view of both its exposure and the protective orders accepted by the exchange. If entry succeeds but a protective order is rejected, the interface must not report the whole operation as successful. This article describes an order-handling design for Binance USDⓈ-M futures. The numbers below are invented to illustrate arithmetic; they are not account results or suggested leverage settings.

  • Porting an Arbitrage Bot to an EVM Chain: Kaia Configuration and Compatibility Checks

    한국어로 읽기 PORTING NOTES / EVM The dangerous shortcut in an EVM bot port is assuming that a successful build means only the addresses need changing. Calculation code may be reusable while contract interpretation and cost estimation still require new evidence. This note reviews a port from a BSC-oriented arbitrage system to another EVM network, using Kaia as the network-configuration example. It does not measure current competition or establish an executable profit opportunity on a particular chain.
