okx/okx-dex-bridge
Use this skill to bridge tokens, cross-chain swap/transfer, move assets between chains, get cross-chain quotes, compare bridge fees, find the cheapest/fastest route, build bridge calldata, check bridge status, track a cross-chain transaction, list supported chains or bridge protocols, or when the user mentions bridging ETH/USDC/tokens from one chain (Ethereum, BSC, Polygon, Arbitrum, Base, Optimism, etc.) to another. Routes through multiple bridge protocols (Stargate, Across, Relay, Gas.zip) for optimal execution. One-shot execute: a single confirmed call approves (if needed), waits for on-chain confirmation, swaps, and broadcasts. Supports fee comparison, destination address specification, and full lifecycle status tracking until fund arrival.
