# xPlug Facilitator The xPlug Facilitator is the infrastructure layer that keeps the xPlug ecosystem fast, reliable, and trustless. It operates quietly in the background — ensuring every payment is processed smoothly, verifiably, and without gas fees. Think of it as the engine that powers all xPlug transactions — for both the SDK and xPlug Pay. ### 99.9% Uptime, Always On Reliability is critical for real-world payments and that’s exactly what the xPlug Facilitator delivers. * 99.9% uptime means transactions are always available and processed instantly. * High-availability architecture ensures redundancy and auto-recovery in case of any network issues. * Distributed network of Facilitators across Solana keeps payments online 24/7. ### Gasless Transactions, Automatically The Facilitator is also what makes xPlug **gasless**.\ It dynamically covers transaction fees for users, so no one needs to hold SOL to interact with the network. How it works conceptually: * User sends a payment through xPlug Pay or SDK. * The Facilitator signs and forwards the transaction to Solana. * The Facilitator absorbs the network fee. * The payment is verified via **x402** and recorded on-chain. ### Multi-Token Support Unlike traditional facilitators limited to USDC,\ xPlug Facilitator is the first x402-compatible facilitator to support custom payment tokens. This means developers and merchants can accept: * USDC default stablecoin option. * USDT and other verified stable assets. * Custom tokens that meet x402’s verification standards. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
