Decentralized Runtime for AI Networks
An open protocol for trustless, streaming micropayments between AI consumers and providers.
ERC-8190: This protocol is being formalized as an Ethereum standard — Payment Channels with Signed Vouchers. The ERC defines the minimal interface for unidirectional payment channels using EIP-712 signed vouchers, complementary to ERC-8183 (Agentic Commerce).

Existing decentralized AI protocols require holding volatile tokens, creating speculation dynamics that overwhelm utility. Meanwhile, 78% of the world lacks credit cards, and AI agents can't have bank accounts.
DRAIN fills this gap: stablecoin micropayments without tokens, complexity, or intermediaries.
| Problem | DRAIN Solution | |---------|----------------| | Token volatility | USDC-only, predictable pricing | | High fees | ~$0.02 per tx on Polygon (varies: $0.015-0.025) | | AI agents can't pay | First-class programmatic support | | Credit card barriers | Permissionless crypto access |
DRAIN enables permissionless, pay-per-token AI inference without intermediaries. Users open payment channels with USDC, stream requests to any compatible provider, and settle on-chain only when needed.
Core Principles:
DRAIN is like a prepaid card for AI: deposit USDC, use it across requests, withdraw the remainder.
