關於Meridian
Meridian 是基於 x402（HTTP 402 機器對機器支付標準）所建立的支付處理器。與直接的钱包對錢包轉帳不同，Meridian 透過代理處理器合約路由支付，實現同鏈轉帳即時結算、在鏈上追蹤平台與資金庫費用，並支援經由 Across 或 Circle 的 CCTP 進行跨鏈結算。它支援多種支付方式（EIP-3009、ERC-2612、Permit2）及批次結算，並在 Base 上提供 MRDN 現金回饋。 核心價值：為 AI 代理提供標準化、非託管的方式，使其能夠跨框架與鏈進行雇用、支付與結算。代理保留自己的錢包；支付透過 API 金鑰及組織層級的存取控制進行驗證。此外，它還支援微型服務與跨框架的勞動力交換。 解決的問題：AI 框架間破碎的支付軌道、代理支付缺乏即時結算與費用核算，以及跨鏈摩擦。Meridian 透過 x402 統一這些問題，並提供可程式化的費用處理與選擇性現金回饋。 近期發展（2026 年 3 月至 9 月）：完成基於 Circle 的奈米支付路徑，利用 CCTP 的銷毀與鑄造機制實現免 Gas 費、批次化的 USDC 結算；推出多代幣預設軌道，結算時間低於 2 秒；導入 UMA 仲裁機制以實現無需信任的退款；並開始建構 mrUSD——一種經由 M0 發行的美元穩定幣。該期間未通報重大負面事件，但該專案仍處於早期階段，且依賴於 x402 的採用。
Meridian is an x402 payments middleware layer on Base that launched alongside its MRDN token on 29 October 2025, founded by Benedict Brady with Aren Rendell, Evan Kim and Kishan Patel, on a one-billion token supply. It matches AI agents and merchants for pay-per-call on-chain settlement: the agent issues a request, the merchant returns a 402 quote, and Meridian's facilitator contract verifies the signature and settles.
Technically it addressed cross-chain and multi-asset settlement first: from November 2025 it used Across as the settlement route, avoiding the up-to-seven-day challenge period for returning to Ethereum from a layer two, and allowed payment in tokens beyond USDC. When Circle released its Agent Stack and sub-cent Nanopayments down to USD 0.000001 on 11 May 2026, Meridian was an early integrator, and the Circle CCTP route is marked complete on its roadmap. Real usage is small: third-party on-chain counts for July 2026 put cumulative settlement at about USD 1.24 million across 57,941 payments, with USD 187,000 and 8,315 payments over thirty days, run by a single settler, against Coinbase's official facilitator at USD 1.57 million and 16.98 million payments.
Strategy and roadmap: Meridian is trying to occupy the neutral settlement layer in the new x402 standard, charging a 1% protocol fee into the treasury on Base transactions while subsidising users with 2% MRDN cashback capped at USD 5 per payment; next it plans UMA optimistic-oracle dispute arbitration and an mrUSD stablecoin issued through M0. The first risk is token structure: only 2.7% of supply circulates, leaving valuation more than thirty times the float. The second is competitive standing, since x402 settlement is currently led by Coinbase, Meridian's share is minimal and concentrated in one settler, and the path dependency is pronounced.
