AlgoVoi Platform Adapters
Drop-in payment adapters for connecting e-commerce platforms, AI agent frameworks, and automation tools to **AlgoVoi** — a compliance-aware crypto payment gateway where agents negotiate a shared stablecoin settlement lane: seven native mainnet chains, with cross-chain settlement negotiated between agents on any two of them. The adapters in this repository are end-to-end tested on the seven native chains (Algorand, VOI, Hedera, Stellar, Base, Solana, Tempo).

What is AlgoVoi?
AlgoVoi is compliance-aware payment infrastructure for stablecoin settlement. The same gateway that negotiates settlement across seven native mainnet chains — in any cross-chain pairing among them — also runs continuous sanctions screening, KYB gating, and a write-once SHA-256 audit chain on every payment — so merchants and autonomous agents don't quietly carry UK MLRs / OFAC / SAMLA exposure they didn't sign up for. Compliance posture is published live at /compliance/attestation.
The compliance perimeter is the product. Multi-chain breadth — seven native mainnet chains (Algorand, VOI, Hedera, Stellar, Base, Solana, Tempo), with settlement negotiated between agents on any two of them rather than fixed to one — and protocol coverage (x402, MPP, AP2, A2A) are how we deliver it on a single endpoint, without merchants having to manage wallets or blockchain integrations directly.
Supported settlement assets:
| Asset | Network | Details |
|-------|---------|---------|
| USDC | Algorand mainnet | Native ASA (ASA ID 31566704), issued by Circle |
| aUSDC | VOI mainnet | Native ASA (ASA ID 302190), Aramid-bridged USDC |
| USDC | Hedera mainnet | HTS token 0.0.456858, issued by Circle |
| USDC | Stellar mainnet | Credit asset issued by Circle (GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPP5RE34K4KZVN); receiver must have a trust line before accepting |
| USDC | Base mainnet | ERC-20 token (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913), issued by Circle |
| USDC | Solana mainnet | SPL token (EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v), issued by Circle |
| USDCe | Tempo mainnet | TIP-20 token (0x20c000000000000000000000b9537d11c60e8b50, 6 decimals); Tempo is a Stripe/Paradigm EVM L1 (chain ID 4217) with USDC as the native gas token |
| ALGO / VOI / HBAR / XLM / ETH / SOL | Any mainnet | Native coin payments also supported on every chain (6/6/8/7/18/9 decimals respectively) |
> These seven are the native chains; agents on different chains negotiate a shared lane and settle once, any cross-chain pairing among them. The hosted AlgoVoi pay rail additionally settles natively on Arc, Monad, Polygon, Arbitrum and OP Mainnet. The platform integration guides and adapter smoke tests in this repository cover the seven native chains above.

What is this repository?
This repository contains **production-ready payment adapters** and **integration documentation** for connecting e-commerce platforms, custom applications, and AI agent services to AlgoVoi Tenant Services.
Included:
- **Recurring / standing-authority subscriptions (Recurr/)** — Tier 2 lets a customer sign ONCE and AlgoVoi auto-pulls per cycle on all 7 chains (Algorand SpendingCapVault, EVM ERC-20 approve, Solana SPL Approve, Hedera HTS allowance, Stellar Soroban auth_entry, VOI). Per-chain wallet-side reference flows + chain-agnostic merchant-side examples. **native-python/algovoi.py v1.2.0+** ships the merchant HTTP wrappers (8 lifecycle methods)
- **Drop-in plugins** for WooCommerce, OpenCart, PrestaShop, and Shopware (tested and deployed)
- **CMS payment gateways** for Drupal Commerce, Easy Digital Downloads (WordPress), and Ghost — all Comet-validated 2026-04-15
- **Native adapters** for PHP, Python, Go, Rust, and TypeScript (zero external dependencies) — all at v1.2.0 with full Tier 2 (recurring) surface
- **Agent protocol middleware** for MPP and AP2 (gate APIs behind payment challenges)
- **AI platform adapters** for OpenAI, Claude, Gemini, Bedrock, Cohere, xAI/Grok, and Mistral (MPP + AP2 + x402, all 7 chains)
- **AI agent framework adapters** for LangChain, LlamaIndex, CrewAI, Hugging Face, AutoGen, Semantic Kernel, Pydantic AI, DSPy, Vercel AI SDK, Google A2A, LangGraph, and Agno — gate LLM-agnostic pipelines, RAG chains, multi-agent crews, and autonomous agents (MPP + AP2 + x402, all 7 chains)
- **No-code / automation adapters** for Zapier, Make (Integromat), n8n, and **X (Twitter)** — drop-in Python classes that bridge AlgoVoi payment flows into any no-code workflow, with webhook verification, MPP + x402 + AP2 challenge generation, and all 14 networks (7 mainnet + 7 testnet); the X adapter auto-posts payment confirmations and checkout links to X via webhook (OAuth 1.0a, stdlib-only, 4-chain mainnet verified 2026-04-18)
