🧭 Choosing a Blockchain

AUDD is issued on multiple leading blockchains, each with its own strengths and trade-offs. If you haven’t yet decided which chain to use, this guide will help you weigh the key factors: speed, cost, ecosystem, security, and use case fit.

There’s no single “best” blockchain - the right choice depends on your application and priorities.

🧩 Key Factors to Consider

When evaluating which blockchain to use for AUDD, consider these core factors that influence performance, cost, and long-term reliability:

⏩ Transaction Speed

Faster blockchains enable near-instant settlement, which is valuable for payments, retail, and high-frequency use cases.
Slower blockchains may still be suitable if your priority is ecosystem depth (such as DeFi integrations, or smart contracts).

💸 Transaction Costs

Some chains offer very low fees, ideal for micropayments or high transaction volumes.
Others have higher fees but compensate with broader adoption, deeper liquidity, or more advanced tooling.

🌏 Ecosystem & Use Cases

If you plan to interact with DeFi protocols, lending platforms, or NFTs, look for chains with mature ecosystems.
For enterprise, remittance, or settlement-focused use cases, speed and compliance features may outweigh ecosystem size.

🚨 Security & Vulnerabilities

All blockchains face technical risks such as congestion, downtime, or smart contract exploits.
Well-established chains may provide stronger network security due to larger validator sets and longer track records.
Newer chains may offer innovation and performance gains but can carry greater operational risks.

🛠️ Developer Tools & Community

Consider the availability of SDKs, APIs, and documentation.
Larger developer communities can mean faster support, better libraries, and more integration guides.

⚖️ Pros and Cons

Each category of blockchain comes with unique advantages and trade-offs; understanding these can help you align AUDD with the right environment for your needs.

Blockchain Type	Pros	Cons	Best Suited For
High-Speed, Low-Cost Chains	Near-instant transactions, low fees, scalable	May have smaller ecosystems or younger track records	Payments, retail, high-volume transfers
Ecosystem-Rich Chains	Mature DeFi/NFT ecosystem, strong developer community, wide adoption	Higher fees, slower settlement times	DeFi, smart contracts, liquidity-focused use cases
Settlement-Focused Chains	Designed for cross-border payments, efficient settlement	Limited smart contract support, smaller DeFi presence	Treasury, remittance, institutional payments
