feat(services): add AlgoVoi — MPP on Algorand, VOI, Hedera, and Stellar

[chopmob-cloud]

Summary

Adds AlgoVoi to the MPP service directory — the first MPP-native payment infrastructure for non-EVM chains (Algorand, VOI, Hedera, Stellar).

• New ALGOVOI_PAYMENT constant (Algorand USDC ASA 31566704, 6 decimals)
• AlgoVoi service entry: blockchain + web categories, first-party, beta
• Two endpoints: payment-gated resource access + on-chain payment verification

What AlgoVoi is

AlgoVoi is a multi-tenant MPP payment infrastructure layer that enables AI agents to pay for services using on-chain USDC — without touching an EVM chain. It's the first complete MPP implementation on Algorand/VOI/Hedera/Stellar.

Chain	Network	Asset	Ticker
Algorand	algorand:mainnet (CAIP-2)	ASA 31566704	USDC
VOI	voi:mainnet	ARC200 302190	aUSDC
Hedera	hedera:mainnet	HTS 0.0.456858	USDC
Stellar	stellar:pubnet	Circle USDC	USDC

Validation

• MPP adapter: v2.1.0, 153/153 tests, full IETF draft-ryan-httpauth-payment compliance including Table 3 challenge echo
• 4-chain smoke tested: 13 April 2026, real 0.01 USDC payments, all chains verified on-chain
• Open-source adapters: chopmob-cloud/AlgoVoi-Platform-Adapters — 17+ eCommerce platform adapters + Python/Go/PHP/Rust native adapters

CAIP-2 reference

For anyone building MPP on non-EVM chains, we've published a CAIP-2 conventions document:
caip2-algorand.md

Test plan

• ALGOVOI_PAYMENT constant is valid PaymentDefaults shape
• AlgoVoi service entry passes TypeScript compilation
• Service appears correctly in mpp.dev/services
• Extension URI resolves: https://api1.ilovechicken.co.uk/ap2/extensions/crypto-algo/v1

Thanks for submitting a service to the MPP directory!

If you want your service included in the curated mpp.dev/services list, complete this checklist before review:

Required

• Your service is live and accepting payments via MPP (not a placeholder or coming-soon)
• You've added your entry to schemas/services.ts following the contributing guide
• Types pass: pnpm check:types
• Build succeeds: pnpm build

Recommended

• Register your service on MPPScan (by Merit Systems) — it follows the standard MPP discovery format and makes your service discoverable by agents immediately, no PR required

Review criteria

We prioritize services that are high quality and novel. We may not approve services that duplicate existing functionality or aren't yet production-ready.

Checklist verification

Service live and accepting payments ✅
AlgoVoi is live at https://api1.ilovechicken.co.uk — the gateway accepts MPP payments across Algorand, VOI, Hedera, and Stellar. The challenge endpoint (/mpp/challenge) and verify endpoint (/mpp/verify) are operational on mainnet and testnet for all four chains.

Entry in schemas/services.ts ✅
The ALGOVOI_PAYMENT constant, service definition, and both endpoints (/mpp/challenge, /mpp/verify) are present and correctly typed in the schema.

pnpm check:types ✅
Passes cleanly on this branch — zero TypeScript errors.

pnpm build
Build fails with RangeError: Maximum call stack size exceeded in rolldown (127 errors). This is a pre-existing toolchain issue unrelated to this PR — the same failure occurs on upstream main with no changes applied. The error is in the rolldown bundler itself, not in any service schema code.

MPPScan registration ✅
AlgoVoi is registered on MPPScan. Server ID: fd75bc4d17a00345263e8d20022b6ccc6e1b7b00d752531f82998f8ea66533fb. The x-payment-info OpenAPI extension is live at https://api1.ilovechicken.co.uk/openapi.json.
