StableCoin

Yala is a modular Bitcoin DeFi infrastructure that connects BTC liquidity with multi-chain ecosystems through its YU stablecoin and MetaMint protocol. It enables Bitcoin holders to earn native DeFi yields across EVM and non-EVM networks securely and seamlessly.

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.

The Stablecoin Narrative describes the evolving industry trend focused on stablecoins, digital dollars, and blockchain-based payment systems. By mapping the value of fiat currencies onto blockchain networks, stablecoins offer stable units of account, efficient settlement solutions, and a foundational infrastructure for global payments within the digital asset market. As RWA, DeFi, cross-border payments, and institutional financial demands continue to expand, stablecoins are transitioning from simple crypto trading tools to essential infrastructure bridging traditional finance and the Web3 economy.

TRC-20 USDT runs on TRON; ERC-20 USDT runs on Ethereum—same issuer stablecoin in different on-chain forms. For deposit, withdraw, or external wallet transfer, network name must match the recipient address chain. In-exchange spot trading without on-chain in/out usually does not require choosing TRC-20 or ERC-20 each time.

Quick Buy completes purchase at a page quote via payment channel/platform flow; P2P matches users with merchants or individuals per ads, with the platform usually locking seller USDT. Quick Buy favors shorter flow; P2P favors local payment and price filtering—they differ in fee structure, confirmation steps, and fraud surface.

Stablecoins are digital assets anchored to the value of fiat currencies, allowing fast transfers, automatic settlement, and worldwide circulation via blockchain technology. With the growing adoption of stablecoins such as USDC, these assets are transitioning from trading instruments to core financial infrastructure, bridging payments, AI agents, and the broader digital economy.

TRON stands as one of the world's leading blockchain networks. Beyond supporting native TRX assets and TRC-20 tokens, it plays a pivotal role in stablecoin payments and on-chain liquidity. As institutional players increasingly enter the digital asset market, the question of how to securely and compliantly hold assets and engage in on-chain activities has become a central focus for the industry.

Driven by rising demand for stablecoin payments, on-chain settlement, and digital asset management, TRON is steadily shifting from a basic blockchain network to a key component of global digital asset financial infrastructure. Robust stablecoin trading and dynamic on-chain liquidity are drawing greater institutional attention to TRON’s ecosystem. Meanwhile, Anchorage Digital’s expansion of TRON custody, TRX staking, and TRC-20 asset support signals a transformation in how institutions engage with the blockchain market.

As institutional investors become more involved in the blockchain ecosystem, the need for secure and compliant digital asset infrastructure is growing. Anchorage Digital recently broadened its support for the TRON network, introducing native TRX staking and TRC-20 asset custody services. This allows institutions to engage with the TRON ecosystem through a regulated platform.
