With the stablecoin market moving away from exclusive US dollar dominance toward greater multi-currency adoption, Onchain FX infrastructure is becoming increasingly critical. Mento Protocol has recently deployed its decentralized FX protocol on Polygon, introducing a USDm/EURm liquidity pool and the euro reserve asset EURØP. This enhances the onchain trading and settlement capabilities of stablecoins beyond the US dollar.

Automated market makers (AMMs) have become the predominant trading mechanism in the DeFi ecosystem, allowing users to swap various crypto assets via liquidity pools. However, as trading scenarios shift from highly volatile cryptocurrencies to stablecoin foreign exchange (FX) markets, traditional AMMs may face challenges such as price deviations and reduced liquidity efficiency. This article compares the AMM and the Fixed Price Market Maker (FPMM) model employed by Mento, examining their differences in price discovery, liquidity management, and cross-border payment use cases, and illustrates why Mento builds multi-currency stablecoin markets using FPMM.

USD stablecoins continue to dominate the global stablecoin market. However, as cross-border payments, corporate treasury management, and financial digitalization advance worldwide, demand for non-USD stablecoins is steadily increasing. Without robust liquidity and on-chain foreign exchange (On-chain FX) infrastructure, however, efficient currency exchange and payments across different currencies remain difficult to achieve.

Bollinger Bands are a volatility-based technical analysis overlay that shows whether price is relatively high or low compared with its recent trading history. Developed by John Bollinger in the 1980s, the indicator uses a middle moving average plus an upper Bollinger Band line and lower Bollinger Band line that expand and contract as market volatility changes.

Bollinger Band Width, or BBW, is a technical indicator that measures how widely the upper and lower Bollinger Bands are separated relative to their middle moving average. Falling BBW indicates volatility contraction, while rising BBW indicates volatility expansion. It helps traders assess market volatility and recognize when quiet price action is turning into a more active market, but it does not predict whether the next price move will be upward or downward.

The Williams %R indicator is a momentum oscillator developed by Larry Williams that shows where the current closing price sits within the recent high-low range. It moves between 0 and -100, with readings above -20 commonly treated as overbought and readings below -80 as oversold. Its main value is timing: Williams %R can reveal when momentum is becoming stretched or shifting near potential reversal points.

As cryptocurrency applications advance, wallets have transitioned from merely storing assets to serving as comprehensive digital financial gateways that integrate trading, yield management, and payment services. Taking BloFin Wallet as a case study, this article examines the operational model of an all-in-one cryptocurrency wallet and explores how trading, Earn, and Visa Card collectively enable a seamless capital cycle.

Williams %R and RSI are both momentum oscillators, but neither is universally better for momentum trading. Williams %R is generally faster and more sensitive to short-term price changes, while RSI is smoother and usually better suited to broader momentum assessment and trend confirmation. Traders looking for early reversal signals may prefer Williams %R; those who want less noise and a more balanced view of momentum may favor the Relative Strength Index.

As the cryptocurrency market continues its transition from asset investment toward daily financial use, users now expect wallets to offer more than just token storage. BloFin Wallet has recently launched perpetual contract trading and Visa payment card services, striving to create a comprehensive digital finance tool that seamlessly integrates trading, asset management, yield generation, and payment functionalities.

Stocks and shares both describe equity ownership, but they are usually used differently. “Stock” is the broader term for ownership in a company or equities as an investment category, while a “share” is an individual unit of that ownership—so you might invest in technology stocks generally, but own 100 shares of Apple specifically.

Gate’s zero-fee model removes its trading fee from eligible U.S. stock and ETF orders, but it does not remove investment risk. Prices can fall, concentrated portfolios can amplify losses, thinly traded assets can produce poor execution, ETFs can diverge from their benchmarks, and USDT settlement can introduce additional currency and stablecoin considerations.

The PPO indicator, or Percentage Price Oscillator, measures trend momentum by expressing the difference between a fast and slow moving average as a percentage of the slower average. Its standardized scale helps traders and investors who use technical analysis, including those trading cryptocurrencies and other securities, compare momentum across assets with different prices and time frames, although its lagging signals still require confirmation from price structure, volume, or another indicator.

The TSI indicator, or True Strength Index, is a momentum oscillator that measures the direction and relative strength of price movement. By comparing double-smoothed price changes with double-smoothed absolute price changes, it filters some short-term noise and helps traders assess whether bullish or bearish momentum is strengthening, weakening, or changing direction.

The PPO vs. MACD choice depends mainly on whether a trader needs relative or absolute momentum. Both are trend-following momentum indicators built from two exponential moving averages, but the Percentage Price Oscillator (PPO) expresses the difference as a percentage, while the MACD indicator shows it as an absolute value. PPO is therefore generally better for comparing momentum across assets with different price levels, while MACD can be more straightforward when analyzing momentum within a single market.
