MGUSD, USDT0, and USDC are three USD-pegged stablecoins with three different multi-chain postures. MGUSD launched on Stellar on June 2, 2026, issued by Bridge (a Stripe company) for MoneyGram, with no cross-chain transport mentioned in the launch release. USDC lives natively on 23 blockchains, with Circle's CCTP V2 coordinating burn-and-mint transfers between them. USDT0 is Tether's omnichain extension of USDT, built on LayerZero's OFT standard, each unit backed 1:1 by USDT in an Ethereum lockbox.
​

None of the three substitutes for the others. They sit at different points on the issuer, transport, and distribution axes. This article walks through each posture, the issuer model behind each, the transport mechanism each uses, and how an intent-routing layer composes with any of them. The frame is structural, not a verdict on which is "best."
​

MGUSD launched Stellar-native, with multi-chain expansion not specified in the June 2, 2026 release. USDC operates across 23 chains via Circle CCTP. USDT0 spans LayerZero-connected chains via the OFT standard. Each posture reflects a different issuer strategy: distribution-network-first for MGUSD, multi-chain-native for USDC, omnichain-wrapper for USDT0.
​

A stablecoin's multi-chain posture is shaped by two design choices: how supply is created on each chain and how value moves between chains. MGUSD today is one chain, one supply. USDC is many chains, each with its own native supply reconciled by CCTP burns and mints. USDT0 is one Ethereum lockbox with mirrored supply on every connected chain. Each fits different integration constraints.
​

Per the June 2, 2026 launch release, MGUSD deploys natively on Stellar. M0 provides the mint/burn smart-contract layer. Fireblocks holds operational and customer wallets. The release names no cross-chain transport partner and no specific multi-chain expansion timeline. MGUSD is, as of June 2026, a single-chain stablecoin.
​

The single-chain posture is deliberate, per the launch release framing. Anthony Soohoo, MoneyGram's Chairman and CEO, is quoted: "MoneyGram is taking a fundamentally different approach. MGUSD is the stablecoin we built for our customers." That framing focuses on distribution into the MoneyGram network, not chain footprint. Stellar's existing payment rails, anchors, and pathfinding sit underneath the launch. As of June 2026, no specific timeline, target chains, or transport mechanism for MGUSD beyond Stellar is publicly disclosed. The release describes Bridge as a "regulated, GENIUS Act-ready issuer," its phrasing.
​

USDC is live on 23 blockchains as of mid-2026, including Ethereum, Solana, Stellar, Base, Arbitrum, Polygon, Avalanche, and 16 others. Circle's Cross-Chain Transfer Protocol (CCTP) moves USDC between supported chains by burning native USDC on the source chain and minting native USDC on the destination chain. No wrapped representations sit in the path.
​

CCTP went live in 2023 and reached V2 in 2024, which reduced finality times and added a fast-transfer mode for supported chains. CCTP V2 went live on Stellar on May 19, 2026 per the Stellar Development Foundation announcement, making Stellar the latest chain to host native USDC with burn-and-mint cross-chain reach. Each chain's USDC contract holds its own minted supply, controlled by Circle-managed deployments, with attestation-based transfers between chains routed through CCTP. The integration surface is broad: most major exchanges, wallets, and DeFi protocols treat USDC as the default stablecoin on whichever chain they support.
​

USDT0 is an omnichain wrapper for Tether's USDT, built on LayerZero's Omnichain Fungible Token (OFT) standard. Each USDT0 unit is backed 1:1 by USDT held in an Ethereum mainnet lockbox. Supply on every connected chain is reconciled through LayerZero messaging. USDT0 is operated by Everdawn Labs in collaboration with Tether and LayerZero.
​

USDT0 was announced on January 16, 2025 and first deployed on Ink. The wrapper exists so USDT can reach chains where Tether has not deployed a native contract, without spinning up a separate canonical issuance per network. Supported chains as of 2026 include Ink, Berachain, MegaETH, Arbitrum, TON, Tron, and others. Native transfers using the OFT standard carry no additional protocol fees, while legacy mesh transfers between TON, Tron, Arbitrum, and Ethereum carry a 0.03% fee.
​

On February 10, 2026, Tether Investments announced a strategic investment in LayerZero Labs. USDT0 had moved more than $70 billion in cross-chain value transfer in under twelve months by that point, per the Tether announcement.
​

Bridge issues MGUSD (and other stablecoins including USDB). Circle issues USDC and EURC. Tether issues USDT, with Everdawn Labs operating USDT0 as the omnichain wrapper. Each issuer takes a different organizational shape. Bridge is an issuance-as-a-service platform. Circle is a vertically integrated issuer. Tether issues directly and relies on a separate operator for omnichain reach.
​

Bridge, acquired by Stripe in October 2024, operates as an issuance platform that other brands plug into. The stablecoin on the front of the token carries the brand of the partner, not Bridge. MoneyGram is the brand on MGUSD. Circle, by contrast, is the brand on USDC and EURC. Circle controls the contracts, publishes monthly attestations via Deloitte, and treats USDC as its own flagship product.
​

Tether issues USDT directly. The omnichain extension USDT0 sits structurally outside Tether's core issuance, operated by Everdawn Labs with LayerZero providing the messaging layer. That separation is part of what lets USDT0 reach chains Tether has not deployed native contracts on. Tether publishes reserve disclosures quarterly via tether.io.
​

MGUSD is on one chain at launch: Stellar. USDC is on 23 chains including Ethereum, Solana, Stellar, Base, and Arbitrum. USDT0 reaches LayerZero-connected chains where Tether does not natively deploy USDT, including Ink, Berachain, and MegaETH, while USDT itself is natively issued on Ethereum, Tron, and several other chains. The footprint shapes which apps can integrate which stablecoin today. A Solana wallet that wants MGUSD has no path at launch. A Solana wallet that wants USDC has a native contract. A Berachain wallet that wants USDT has USDT0. The difference is about which lanes each stablecoin runs on, not which one is "more useful" in the abstract.
​

MGUSD does not move between chains today. USDC moves via Circle CCTP burn-and-mint. USDT0 moves via LayerZero OFT messaging, with each unit backed by USDT in an Ethereum lockbox. Each transport model trades off differently on trust assumptions, latency, fee economics, and which chains can be reached.
​

CCTP burns native USDC on the source chain and mints native USDC on the destination chain, using Circle's attestation service as the cross-chain message authority. Holders end up with native USDC on the destination, not a wrapped representation. LayerZero OFT moves a USDT0 unit by burning on the source chain and minting on the destination, with destination supply backed by USDT in the Ethereum lockbox. The trust assumption sits with LayerZero's DVN (Decentralized Verifier Network) configuration and the Everdawn Labs operational layer.
​

MGUSD's cross-chain story is, as of June 2026, undocumented. The launch release names Stellar as the launch chain. Whether multi-chain reach will arrive via Bridge's issuance stack, a third-party messaging protocol, or some other mechanism is not stated.
​

A cross-chain stablecoin intent router treats CCTP, LayerZero, and other transport rails as inputs. The user expresses a destination intent. The router chooses which stablecoin and which rail satisfy that intent. Eco Routes is one example of this layer, composing with USDC over CCTP, USDT0 over LayerZero, and any future MGUSD cross-chain transport. The router does not pick the "right" stablecoin. The application or end user does. Peer aggregators like Across, LI.FI, Squid, and Jumper sit at the same layer with different routing logic, chain coverage, and economic models. None of these aggregators issues a stablecoin. They route the ones issuers have already deployed.
​

MGUSD fits payments stacks anchored to MoneyGram's distribution network and Stellar's payments rails. USDC fits stacks needing broad chain reach, deep exchange liquidity, and DeFi integration. USDT0 fits stacks needing USDT exposure on chains where Tether does not natively deploy. A developer building a remittance flow that ends in cash at a MoneyGram counter benefits from MGUSD as the final-leg digital dollar. A trader moving liquidity across Ethereum, Solana, and Base benefits from USDC because native deployments exist on all three. A DeFi protocol launching on Berachain benefits from USDT0 because the wrapper reaches there before Tether's native deployment does. The three stablecoins layer rather than compete.
​

The table below summarizes the structural differences across MGUSD, USDT0, and USDC as of June 2026. All three are USD-pegged. Their issuer, chain footprint, cross-chain transport, and intended distribution diverge.

The June 2, 2026 launch release covers MGUSD's issuer, partners, chain, and intended distribution. Several multi-chain specifics are not detailed: whether MGUSD will deploy on additional chains, what transport mechanism would carry it cross-chain, the timeline for any such expansion, and how it would interoperate with CCTP, LayerZero, or other rails. For comparison, USDC's footprint expanded chain by chain over several years, each addition announced by Circle with transport details. USDT0's omnichain reach grew over its first year via LayerZero. MGUSD's story so far is one launch on one chain. The trajectory will be visible as MoneyGram, Bridge, and partners publish further detail.
