# What is Allbridge Core?

{% hint style="info" %}
Allbridge Core liquidity pools were discontinued in July 2026. If you were a liquidity provider, please visit the [compensation page](https://core.allbridge.io/pools/compensation).
{% endhint %}

Allbridge Core is a cross-chain bridge designed for seamless transfers of dollar-pegged stablecoins. It enables users and applications to move USDC, USDT and USDe across a wide range of blockchains, including most EVM networks as well as Tron, Solana, Sui, and Stacks.

Instead of wrapped assets or bridge-owned liquidity, Allbridge Core routes each transfer through the native cross-chain standard of the asset being moved: Circle’s CCTP and xReserve for USDC, and LayerZero’s OFT standard for USDT and USDe. The user always sends and receives the canonical stablecoin on each chain, and the amount received equals the amount sent minus the displayed fees.

The system is fully non-custodial. Allbridge Core smart contracts prepare the transfer and collect fees, while the token movement itself is executed by the underlying protocol contracts. Allbridge never has access to user funds.

## Key Features

### Native cross-chain transfers via CCTP, xReserve and OFT

Allbridge Core moves stablecoins natively between blockchains without wrapping and without intermediate liquidity pools.

* USDC transfers use Circle’s Cross-Chain Transfer Protocol (CCTP and CCTP V2) or xReserve, Circle’s infrastructure for USDC-backed stablecoins.
* USDT and USDe transfers use LayerZero’s Omnichain Fungible Token (OFT) standard.

Because no swap is involved, there is no exchange rate and no price impact on a transfer.

### One interface for every route

Allbridge Core selects the mechanism available for the chosen route and shows the full fee breakdown before the transfer is sent. Transfer progress can be tracked in the app, and past transfers are available in the transfer history.

### Flexible fee payment and optional gas top-up

Users can pay bridge fees in the gas token, in the stablecoin being transferred, or in [ABR0](/product/abr0-token.md) at a discount.

Transfers can also include an optional gas top-up, sending a small amount of the destination chain’s gas token to ensure the user can cover their first transactions after bridging.

### Non-custodial and audited

Allbridge Core does not hold user liquidity. All token movement is performed by the CCTP, xReserve and OFT contracts. The protocol has undergone multiple independent audits, with ongoing monitoring to maintain security across all supported networks.

## Supported Blockchains

Allbridge Core supports major blockchain ecosystems used for stablecoin transfers, including:

* EVM chains (Ethereum, Polygon, Avalanche, Arbitrum, Base, Optimism, Unichain)
* Tron
* Solana
* Sui
* Stacks

Stellar support is temporarily unavailable while the Stellar CCTP implementation is pending audit.

The main stablecoin assets supported are USDT, USDC and USDe, and new routes and assets are added over time as the network expands. Please check [https://core.allbridge.io](https://core.allbridge.io/) for currently supported routes on each blockchain.
