This applied predictive-analytical study was conducted in Tehran, Iran, during 2025–2026. The behavioral validation sample consisted of 384 active cryptocurrency market participants. The longitudinal dataset included 2,190 synchronized daily observations for USDT, USDC, and DAI. Data comprised historical prices, trading characteristics, transaction volume, active addresses, exchange inflows and outflows, net exchange flows, large-holder transactions, supply changes, and deep learning-derived sentiment indicators. Sentiment was extracted from cryptocurrency-related textual data using transformer-based natural language processing. An integrated Attention-LSTM model was developed and compared with Support Vector Regression, Random Forest, Extreme Gradient Boosting, conventional LSTM, and GRU models. Chronological training, validation, and test partitions were used, and SHAP analysis assessed feature importance and direction. The integrated Attention-LSTM model demonstrated the strongest out-of-sample performance, with MAE = 0.00196, RMSE = 0.00324, MAPE = 0.195%, R² = 0.939, and directional accuracy = 83.23%. It outperformed the Attention-LSTM model without sentiment, which achieved RMSE = 0.00453 and R² = 0.881. Ablation analysis showed that the full integrated model reduced RMSE by 53.31% relative to the historical-price-only model. The model achieved R² values of 0.947, 0.942, and 0.921 for USDT, USDC, and DAI, respectively, and directional accuracy reached 90.32% during high-deviation periods. SHAP analysis identified negative sentiment intensity, net exchange inflow, previous-day peg deviation, on-chain transaction volume, sentiment dispersion, and large-holder transaction volume as the most influential predictors. Integrating on-chain, market, and sentiment information within an explainable Attention-LSTM framework substantially improves stablecoin price forecasting and provides interpretable early-warning signals of peg instability.</p> https://www.journalmbs.com/index.php/jmbs/article/download/433/403
