Welcome to the Token Metrics Moon Awards, a prestigious cryptocurrency industry accolade that recognizes platforms, projects, and initiatives that have significantly impacted the industry. The latest addition to the Moon Awards is the Top ZK Rollup in 2024.

Selection Process

At Token Metrics, we emphasize our audience, considering them the foundation of our operations. Our selection process is firmly rooted in engaging with the community, ensuring that our awards' results authentically reflect crypto enthusiasts' sentiments and experiences.

Through engagement with our community members, we have compiled a comprehensive list of the Top ZK Rollup in 2024 based on extensive survey data and user votes.

This guide aims to explore ZK Rollups in-depth, highlighting their advantages and considerations, alongside an overview of top ZK rollup projects slated to dominate in 2024.

What are ZK Rollups?

ZK Rollup is a transformative layer-2 scaling solution that enhances blockchain scalability and efficiency by moving computation and state storage off the main chain. They operate by:

  • Bundling Transactions: Transactions are aggregated into batches and processed off-chain. This method significantly reduces the on-chain footprint, lowering gas costs and increasing throughput.
  • Zero-Knowledge Proofs: A core feature of ZK Rollups is using zero-knowledge proofs to validate transactions off-chain before finalizing them on the main chain. This ensures that all transactions are legitimate without revealing any underlying data, thus preserving privacy and security.
  • On-Chain Data Storage: ZK Rollups store transaction data on the layer-1 network while the computation is done off-chain. This approach maintains the integrity and security of the blockchain, leveraging the robustness of the base-layer network for settlement purposes.

Operators play a crucial role in managing these rollups, which can be either a centralized sequencer or a decentralized proof-of-stake system with validators. 

This flexibility allows for different governance models, further enhancing the adaptability of ZK Rollups to various blockchain ecosystems. 

Moreover, advancements like the zero-knowledge EVM (zkEVM) are pushing the boundaries of what's possible, enabling more complex computations and applications to benefit from the scalability and efficiency of ZK Rollups.

Why stablecoin issuers matter in September 2025

Stablecoins have become crypto’s settlement rail, powering exchanges, DeFi, remittances, and payments. In 2025, clarity is improving and liquidity is consolidating—so choosing stablecoin issuers with sound reserves, clear disclosures, and fit-for-purpose design matters more than ever.
Definition: A stablecoin issuer is the organization or protocol that mints and redeems a token designed to track a reference asset (usually USD), with reserves and/or mechanisms intended to hold the peg.
This guide evaluates the leading issuers globally and maps their best use cases—from high-volume trading to compliant payments and decentralized collateral. We focus on reserves quality, transparency, networks supported, institutional access, fees, and regional eligibility. Secondary topics include “USDC vs USDT,” euro/SGD options, and decentralized alternatives that can complement centralized choices. Circle+2Circle+2

How We Picked (Methodology & Scoring)

  • Liquidity (30%): Scale of circulation and exchange/DeFi depth for tight spreads and fast settlement.

FAQs

1) What are the main types of stablecoin issuers?
Three broad models: (1) Fiat-backed (Circle, Paxos, First Digital Labs), (2) Overcollateralized crypto-backed (MakerDAO DAI; Liquity), and (3) Synthetic/hedged (Ethena USDe). Each has distinct reserve/risk properties. docs.ethena.fi+3Circle+3Paxos+3

2) Which stablecoin is best for trading liquidity?
USDT typically leads on global CEX depth and pairs, with USDC often preferred for fiat-connected flows and DeFi. Choose based on venue support and treasury needs. Tether+1

3) Can U.S. users access every stablecoin?
No. PYUSD is for eligible U.S. PayPal/Venmo users; some protocols (e.g., Ethena) restrict U.S. access to their app. Always check terms. PayPal+1

4) How do fees work for minting and redeeming?
Paxos states no fees for mint/redeem USDP/PYUSD for primary clients; Circle has institutional schedules; Tether lists platform fees. Secondary-market trades still incur exchange/gas costs. Paxos+2Circle Help+2

5) Are euro or SGD stablecoins useful?
Yes. EURC/EURe enable euro settlements under EU rules; XSGD supports APAC rails and FX paths versus USD stables. Circle+2Monerium+2

6) Is DAI safer than fiat-backed coins?
“Safer” depends on your risk lens. DAI reduces bank/custodian reliance but adds crypto-collateral and governance risk; fiat-backed coins rely on custodians and regulators. Diversification is common. docs.makerdao.com

Conclusion + Related Reads

If you need global trading liquidity, start with USDT/USDC. For enterprise-grade compliance, Circle/Paxos shine. For decentralized resilience, DAI (and Liquity) fit. For regional rails, consider XSGD (APAC) and EURe/EURC (EU). Pair the right issuer with your use case, then monitor peg, reserves, and policy changes over time.

Why Fiat ↔ Crypto On/Off-Ramps Matter in September 2025

Getting money into and out of crypto should be fast, safe, and compliant. In 2025, wallets, dapps, exchanges, and fintechs increasingly rely on crypto on/off-ramp providers to convert fiat to tokens and cash back out to bank rails—all without forcing users to bounce between apps. Definition: an on-ramp lets users buy crypto with fiat; an off-ramp lets them sell crypto back to fiat and withdraw to bank accounts or cards. This guide is for product leaders, devs, and advanced users comparing coverage, fees, and risk controls across global options. We score providers on liquidity, security, asset/market coverage, costs, UX, and support, then recommend the best fits by use case. Secondary angles we considered: fiat to crypto onramp, crypto off-ramp, and common flows like “buy crypto with bank transfer.”

How We Picked (Methodology & Scoring)

  • Liquidity (30%) – depth, uptime, and quote quality across assets/fiat rails.

  • Security (25%) – audits, certifications, KYC/AML controls, trust center disclosures.

  • Coverage (15%) – supported countries, payment methods, off-ramp payout rails.

  • Costs (15%) – transparent fees/spreads; promos (e.g., USDC zero-fee tiers).

  • UX (10%) – speed (KYC/settlement), embeddable widgets, developer docs.

  • Support (5%) – docs, SLAs, live support, incident comms.

Data sources: official product/docs and security pages; licensing and disclosures; limited cross-checks with widely cited market datasets. We only link to official provider sites in this article. Last updated September 2025.
