### &#x20;<mark style="color:$primary;">**Technical Highlights**</mark>

This section breaks down the core technology powering the PaywithCrypto platform:

&#x20;<mark style="color:$primary;">**Wallet Architecture**</mark>

* Non-Custodial HD Wallet: Users control their own private keys, ensuring ownership of their assets. HD (hierarchical deterministic) structure allows for the creation of multiple addresses from one seed.
* Encrypted Storage: Private keys are encrypted using each device’s secure enclave (i.e., Apple Secure Enclave or Android Keystore), ensuring they are never exposed or stored on a central server.

&#x20;<mark style="color:$primary;">**Supported Blockchain Networks**</mark>

Native support for major public chains including:

* Ethereum (ERC-20)
* BNB Smart Chain (BEP-20)
* Polygon (low-cost Layer 2 option)
* Tron (for high-speed, low-fee use cases)
* Modular integration framework allows for additional networks (e.g., Solana, Base, opBNB) as market demand evolves.

&#x20;<mark style="color:blue;">Security Features</mark>

* Biometric Authentication: Users can enable fingerprint or face recognition for wallet access.
* Anti-Phishing Protocols: Detects suspicious links and verifies merchant QR codes before sending funds.
* Encrypted Seed Backup: Users are guided to back up their seed phrases securely, with the option of cloud-encrypted vaults.

&#x20;<mark style="color:$primary;">**Regulatory Compliance**</mark>

* Integrated AML/KYC: In collaboration with licensed Virtual Asset Service Providers (VASPs), all fiat conversion and merchant onboarding flows include identity checks.
* Transaction Monitoring: On-chain analytics tools monitor for suspicious activity to comply with anti-money laundering (AML) regulations.

&#x20;
