Allbridge

Allbridge is a cross-chain bridge specializing in stablecoin transfers between Solana and other major blockchains. The protocol has carved a niche by focusing on reliable, low-cost stablecoin bridging — a critical use case for DeFi users who need to move USDC, USDT, and other stablecoins between networks. Allbridge Core uses a liquidity pool model where each supported chain has its own stablecoin pool. When a user bridges from one chain to another, stablecoins are deposited into the source chain pool and withdrawn from the destination chain pool. This model avoids wrapped tokens entirely — users receive native stablecoins on the destination chain. The protocol supports USDC and USDT bridges between Solana, Ethereum, BSC, Polygon, Arbitrum, and other networks. Transfer times vary by chain but typically complete in minutes. The fee structure is based on pool rebalancing costs, meaning fees are lower when transfers help rebalance pool ratios and higher when they increase imbalance. Allbridge also offers liquidity provision for users who want to earn yield by supplying stablecoins to bridge pools. LPs earn a share of bridge fees proportional to their pool contribution. The protocol has been audited and maintains a focus on security, given the high-value nature of bridge transactions.
