#cross-chain

Live cross-chain bridge data from Across, one of the largest intent-based bridges, which moves USDC, ETH, WBTC and other assets between Ethereum and its rollups (Arbitrum, Base, Optimism, Polygon, zkSync, Linea, Blast, Scroll and more) using a relayer network and a single unified liquidity pool. The quote endpoint prices a bridge transfer — the relayer capital fee, gas fee, LP fee, total fee, the amount received and the estimated fill time. The routes endpoint lists every supported bridge route (origin chain, destination chain, token). The limits endpoint returns the min and max bridgeable amount for a route. The chains endpoint lists supported chains. Read live from Across, nothing stored. This is Across's own cross-chain bridge fee, route and fill-time layer — distinct from DEX, lending, staking and price feeds.

Live cross-chain liquidity data from THORChain — the decentralised cross-chain automated market maker (AMM) that swaps native assets (BTC, ETH, BCH, AVAX and more) across separate blockchains without wrapping or bridging, settling every trade through its native RUNE asset and continuous liquidity pools. Read straight from a public THORNode REST endpoint as clean JSON. List every liquidity pool with its RUNE and asset depth, RUNE price and USD price, pool units and status; pull one pool's full depth and pricing; read the protocol's economics — total bonded RUNE, effective security bond, reserve and bonding / liquidity APY; get the current inbound vault address, router and gas rate for every connected chain plus halt flags; or read the last observed and signed block height per connected chain, THORChain's cross-chain heartbeat. Live, no cache. This is THORChain's cross-chain AMM, liquidity-pool and vault layer — distinct from single-chain explorers and from price feeds: continuous liquidity pools settled in RUNE.
