Add AlgoVoi multi-chain payment gateway under Payments

[chopmob-cloud]

Summary

Adds AlgoVoi under Hedera Projects > Payments.

AlgoVoi is a UK-registered multi-chain crypto payment gateway that accepts HBAR and USDC on Hedera via hosted checkout, with on-chain memo binding for payment verification. It ships open-source eCommerce adapters (WooCommerce, Magento, Shopware, OpenCart, PrestaShop, Drupal Commerce and others) and conversational bot checkout via Telegram, Discord, X and Viber.

Hedera-specific notes:

• HBAR and USDC accepted on the Hedera mainnet.
• Mirror-Node based on-chain verification (no Mirror Node operator required for the merchant).
• Wallet support via Reown WalletConnect — the verifier accepts both ED25519 and ECDSA secp256k1 signatures and handles the EIP-191 envelope used by Hedera WC wallets.

Quick update for the listing context: AlgoVoi is now live across all 8 supported chains including Hedera. The Hedera leg uses HTS USDC (token 0.0.456858) at receiver 0.0.10376692 (associated and unfrozen). Public verification: 402 challenges at https://api.algovoi.co.uk/agent-trust-bench/cheap return 8 accepts[] legs, one of which is the Hedera leg. The MCP server (v1.4.3 on PyPI and npm) also exposes Hedera as a native network. Happy to provide any additional info if useful for the listing review.
