Build Unchained Apps
summary
Avail Nexus claims developers can deploy once and pull user liquidity from anywhere, turning many 1→1 bridges into a single N→1 bridgeAndExecute that can optionally call a contract after funds arrive. The SDK offers core methods bridge, transfer, bridgeAndExecute and cross-chain swaps, React Widgets and shadcn Elements, simulation tools and requires an EIP-1193 wallet provider. Demo shows simulated N→1 deposits (e.g., pull USDC from Base/OP/Arbitrum), gasless user-side calls, and unified balances across ~12 chains with solver-dependent latency.
