PayGrid

PayGrid is a stablecoin payment clearing network designed for payment service providers (PSPs), fintechs, and developers building cross-border payment infrastructure. Launched in early 2025, it positions itself as the first PSP-driven clearing network for blockchain payments — a neutral, non-custodial layer that matches counterparties with opposite payment flows, settles at the mathematical midpoint between their rates, and captures value that would otherwise be lost to spread costs and MEV extraction.

The Problem PayGrid Solves

Cross-border stablecoin payments face a structural inefficiency that orchestration tools alone cannot fix: prefunded float. Payment service providers must maintain stablecoin liquidity on both ends of every corridor, tying up capital in the same way that traditional banking's nostro/vostro accounts do — an estimated $4 trillion sitting idle globally in legacy systems.

Beyond capital lockup, every stablecoin payment corridor carries a spread. PSPs sourcing liquidity for USDT/NGN or USDT/KES corridors pay the spread on both legs, because there is no neutral mechanism for counterparties with opposing flows to find each other. PayGrid describes this as the core gap: "every corridor costs you the spread — every time you source the other side."

Existing solutions — orchestration platforms, dynamic rebalancing, credit lines — treat the symptoms rather than the root cause. PayGrid argues the missing piece is a dedicated clearing layer modeled on how traditional financial infrastructure like CLS Bank and Visa's multilateral clearing works, but built natively for stablecoins and public blockchains.

How It Works

PayGrid operates through a programmable clearing engine with two interconnected functions: FX corridor matching and chain-abstracted payment intent execution.

Corridor matching works through a three-step process. First, participants disclose their corridor, side, and best executable rate into a private order flow system. Second, PayGrid identifies counterparties with opposing flows on identical corridors. Third, transactions settle at the mathematical midpoint between both parties' submitted rates — a "mid-crossing" that eliminates dealer spread for both sides. Opposing flows net against each corridor before any surplus is routed to liquidity providers, reducing gross settlement obligations through multilateral netting.

Participants retain custody of funds throughout. PayGrid does not take counterparty risk or hold assets.

Payment intent execution is handled through the chain-abstracted Payment API, launched in January 2025. The API processes payments across four steps: corridor routing and price discovery, payment intent authorization (capturing delegated permissions from the payer), submission to the PayGrid Clearing Gateway, and status tracking via instant payment notifications. Developers integrate once and gain access to payment execution across Solana and five EVM-compatible networks.

A key technical element is MEV handling. Every PSP processing blockchain payments generates MEV in the market but typically captures none of it — that value accrues to external searchers and validators. PayGrid's architecture redirects this through "positive MEV capture" and "negative MEV protection," redistributing the extracted value to network participants rather than losing it to third parties.

Key Products and Features

Programmable Payment Clearing Engine: Context-aware clearing workflows that batch compatible payments, optimize execution costs, and apply programmable pre/post-execution hooks for custom business logic.

Chain Abstracted Payment API: A single API integration for payment flows across Solana and EVM chains. The API abstracts gas costs, supporting gasless transactions via EIP-2612 and custom payment intent design allowing payment in stablecoins instead of native gas tokens. It handles corridor routing and manages the full intent lifecycle.

Grid Network Protocol: An open-source, modular on-chain payment intent protocol built in Solidity, published under the AGPL-3.0 license on GitHub. The protocol handles on-chain payment operations and serves as the settlement layer underneath the API.

Paygrid SDK: A TypeScript SDK (Apache-2.0 license) for developers to integrate the chain-abstracted payment stack directly into applications and orchestration workflows.

FX Clearing for African Corridors: The initial live corridors include USDT/NGN (Nigerian naira) and USDT/KES (Kenyan shilling), with additional African corridors available on inquiry. These corridors represent high-spread markets where mid-market matching generates the most meaningful savings for participants.

Supported Networks and Assets

PayGrid supports Solana plus five EVM-compatible networks, with planned expansion to additional chains. The stablecoin focus is primarily on USDC and USDT, which account for over 90% of volume in analyzed transactions, with support for three main stablecoins at launch.

The wallet-agnostic architecture accommodates deposit accounts, self-custodial wallets, smart contracts, and embedded wallets, making the API flexible for different PSP treasury structures.

Open Source and Technical Transparency

Both core codebases are publicly available on GitHub under the paygrid-tech organization. The grid-network smart contract repository (Solidity, AGPL-3.0) contains the on-chain protocol logic with activity through mid-2025. The paygrid-sdk (TypeScript, Apache-2.0) provides the developer-facing integration layer. The open licensing and public code allow independent inspection of the protocol mechanics.

Team and Background

PayGrid is headquartered in the United States. Khalid Al-Jaaidi is named as author of multiple research and market-analysis posts on the PayGrid blog from mid-2024 onward, covering stablecoin adoption challenges, the clearing-versus-orchestration distinction, and structural shifts in global payments infrastructure. No funding rounds have been publicly disclosed.

Fit in the Solana Ecosystem

PayGrid is one of a small number of projects building payment-specific clearing infrastructure that explicitly includes Solana alongside EVM networks. As Solana captured a growing share of stablecoin transfer volume through 2025, with institutional integrations from Visa, Stripe, and Worldpay, demand for PSP-grade clearing infrastructure on Solana has grown alongside it.

PayGrid treats Solana as a first-class settlement network alongside EVM chains, combined with chain abstraction that unifies payment flows across the ecosystem. PSPs and fintech operators building on Solana can use the Payment API to access corridor matching, mid-market rate execution, and MEV value capture without building this coordination layer themselves.
