Why not just use my wallet's built-in bridge?
Convenience fees. MetaMask embeds 0.875% and Phantom 0.85% into their built-in swap/bridge quotes — roughly $8.75 per $1,000 — on top of the route's own cost. The same routes are available without that markup.
Which bridge is safest?
Intent-based systems (Across, Relay, deBridge) avoid the classic lock-and-mint honeypot design and settle in seconds. For native USDC, Circle's CCTP (surfaced via LI.FI routes) burns and mints real USDC with no wrapped-asset risk.
