Frequently Asked Questions (FAQ)
Q: What is a bridging aggregator?
A: A bridging aggregator routes your cross-chain transactions through the most efficient bridge based on cost, speed, and security—automating what would otherwise require manual comparison.
Q: Are cross-chain bridges safe?
A: Security varies by protocol. Non-custodial bridges like Connext and Synapse offer higher trustlessness, but always verify audit status and community reputation before use.
Q: Which bridge is fastest for stablecoin transfers?
A: Across Protocol and Celer cBridge lead in speed due to optimistic relayers and instant finality models—especially effective for L2-to-L1 or L2-to-L2 movements.
Q: Do I need a native token to use these bridges?
A: Not always. Some platforms like Arbitrum Bridge and Portal don’t require a native token, while others (e.g., Synapse with SYN) use them for governance and incentives.
Q: Can I bridge stablecoins to non-EVM chains like Solana?
A: Yes—Portal Token Bridge and Rango Exchange support non-EVM networks including Solana, enabling true multi-chain interoperability.
Q: How do bridging fees work?
A: Fees depend on network congestion, route complexity, and whether third-party relayers are involved. Aggregators like Rango help minimize costs by selecting optimal paths.
