What is Allbridge Core?

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

Unlike traditional bridges that rely on wrapped assets, Allbridge Core uses a unified virtual stablecoin model to connect independent liquidity pools on different chains. This approach delivers a faster, safer, and more capital-efficient way to move stablecoins between ecosystems.

The system is fully non-custodial. Smart contracts on each supported chain hold all liquidity, execute stable-swap conversions, and enforce the invariant that binds the pools together. Allbridge never has access to user funds—only the pool contracts can move assets.

Key Features

Native cross-chain transfers powered by multi-chain liquidity pools

Allbridge Core moves stablecoins natively between blockchains without wrapping.

Each supported network has its own stablecoin pool, and these pools are connected through a virtual asset (vUsd). This architecture allows transfers to execute through a stable-swap mechanism while all assets always remain native to their chains.

Transfers use invariant-based stable-swap math to ensure predictable execution and efficient pricing. Pool imbalances naturally create arbitrage opportunities, helping keep liquidity aligned across all chains.

Flexible fee payment and optional gas top-up

Users can pay bridge fees either in the gas token or in the stablecoin being transferred.

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.

Real-time rewards for liquidity providers

Liquidity providers earn 80% of all transfer fees. Rewards are added instantly with each transaction, without lockups or withdrawal restrictions. Historical performance data helps LPs evaluate volume and yield trends for each pool.

Additional transfer options on selected routes (CCTP & OFT)

Where supported, Allbridge Core can route transfers through Circle’s CCTP or LayerZero’s OFT standards. These options provide alternative transfer mechanisms for assets that support their own native cross-chain standards, such as USDC via CCTP and USDT via OFT.

Non-custodial and audited

All liquidity is held directly by smart contracts on each chain, not by Allbridge. 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, BNB Chain, Polygon, Avalanche, Arbitrum, Base, Celo, Optimism, Linea, Unichain, Sonic)

• Tron

• Solana

• Sui

• Stellar

The main stablecoin assets supported are USDT and USDC and new pools and assets are added over time as the network expands. Please check https://core.allbridge.io for currently supported assets on each blockchain.
