Welcome to Allbridge Blog

Cross-chain stablecoin transfers are often messy: new wallets, missing gas, and confusing user flows lead to lost conversions.

Allbridge Core changes that.

With a single integration, you unlock seamless, gas-ready transfers across Ethereum, Tron, Solana, Stellar, Sui, Arbitrum, and more. Whether through SDK, REST API, or a smart contract proxy, Allbridge Core adapts to your stack, allowing your users to move funds effortlessly and your product to scale without friction.

You’re probably familiar with Ethereum or other networks that work in a similar way — like BNB Chain or Polygon. These EVM-based blockchains share a common structure, so tools, apps, and user experiences often feel the same across them.

But not all blockchains follow this model. Some are built differently from the ground up. While some of these networks may add features to make things feel more familiar to EVM users, the core technology often works in its own unique way. And for users bridging assets or interacting across chains, those differences can matter.

This article is part of a series focusing on non-EVM blockchains supported by Allbridge Core — specifically Solana, Tron, Stellar, and Sui. Each one has its own architecture and approach, and in this piece, we’ll take a closer look at Stellar and how it’s different from the EVM chains you might be used to.

What Is Positive Arbitrage on Allbridge Core?

What if you could earn money just by bridging stablecoins—in the right direction?

One of the common bridge architecture approaches is to rely on liquidity pools. Tokens go into one pool and are paid out from another. When too many users bridge assets to the same chain, the pool on the receiving end gets drained, and the one on the sending side gets overfilled. This imbalance makes it harder for liquidity providers to withdraw their funds, so many bridges discourage it by raising fees.

But Allbridge Core flips the script.

Instead of punishing imbalanced transfers, Allbridge Core actually rewards users who help bring balance back. It does this by adjusting exchange rates between stablecoins on each side—meaning you might end up receiving more than you send. That’s not a bug — that’s positive arbitrage.

It’s a win-win:

• You profit, just for bridging in the “right” direction.
• The ecosystem stays healthy, with pools balanced across chains.

Positive arbitrage is built into Allbridge Core’s stable-swap-inspired logic. You don’t need to understand the underlying math, you just need to know this: when pools are out of balance, there’s money to be made.

Messaging: The Hidden Hero of Bridging

When users bridge stablecoins across blockchains using Allbridge Core, the process looks almost magical. You send USDT or USDC on one chain — and seemingly instantly, it appears on another. But behind that seamless experience lies an essential and often overlooked piece of infrastructure: messaging.

To understand messaging, think of bridging like teleportation. The stablecoin doesn’t physically travel from one place to another — instead, it’s locked up on the source chain, and a new amount is released on the destination. But for that to work, both ends need to stay in perfect sync. And that’s where messaging comes in.

Messaging is how Allbridge Core tells the destination chain what just happened on the source. It’s a set of precise instructions: how much was sent, which token, where it should go. Without this invisible coordination layer, teleportation wouldn’t work — you’d either lose the asset in transit or duplicate it.

In short, messaging is what allows two completely separate smart contracts on different chains to behave like they’re part of the same system. It’s not an optional add-on — it’s the invisible engine that makes decentralized bridging possible.

Allbridge Core is a cross-chain protocol that enables seamless transfers of stablecoins like USDT and USDC across a wide range of supported blockchains — including EVM networks, Solana, Tron, Sui, and others.

At its core, Allbridge follows a concept familiar to many in DeFi: liquidity pools that allow assets to be swapped based on a stable swap formula. But instead of maintaining a single pool with multiple assets on one chain, Allbridge Core distributes these pools across different blockchains. Each pool holds a single stablecoin, and they’re connected through a cross-chain messaging system that allows value to move from one chain to another.

To support this model, Allbridge Core introduces an internal mechanism that behaves like a virtual stable swap — enabling users to swap stablecoins across chains without relying on wrapped assets or centralized custody.

In this article, we’ll break down how the system works:

• how liquidity pools are structured and how a virtual token called vUsd is used internally,
• what actually happens during a cross-chain transfer,
• how the pools stay balanced, and
• how liquidity providers (LPs) earn rewards in real time.

We’ll also address common questions like:

• Why do some swaps offer better rates than others?
• What causes pool imbalances?
• How does Allbridge Core maintain long-term equilibrium without external intervention?

Let’s begin with the foundation: how liquidity pools are structured in Allbridge Core, and why vUsd is key to making cross-chain swaps possible.
