Build a 1 Click Cross-Chain Experience with Avail Nexus SDK
summary
Avail Nexus SDK offers a concrete workflow: a JavaScript SDK that aggregates portfolio balances, unified balances, builds intent hashes, simulates steps, then performs bridge-and-execute calls to move tokens and immediately run a target contract. Demo shows integrating Nexus into a Next.js preview repo, simulating and bridging 10 USDC, then executing a supply on Base successfully (with a few demo edge-case UI bugs). Supports major EVM chains (Ethereum, Optimism, Arbitrum, Base, Polygon, Scroll), requires on-chain liquidity and does not accept custom non-EVM networks.
