Avail

Build custom multi-chain experiences with the Avail Nexus SDK and API. Nexus gives frontend teams TypeScript control and backend teams flexible APIs for accessing balances, bridging, swapping, transfers, exact-in and exact-out transactions, and bridge-and-execute workflows. Applications define the intended outcome, while Nexus coordinates eligible balances, liquidity, swaps, routing, settlement, and gas across supported chains. Developers can use it to create branded funding, payment, trading, treasury, and other complex cross-chain workflows without building or integrating each underlying bridge and execution path separately.

Built for trading platforms, prediction markets, DeFi apps, and payment products, Avail Deposits helps apps increase funded accounts, deposits, and payment conversion by letting users fund an account or complete a payment with assets held across supported chains, wallets, apps, exchanges, QR deposits, and onramps. Users can pay with stablecoins or other supported tokens, while Avail combines eligible balances into a Unified Balance and handles any required swaps, bridging, routing, and gas. The app receives the required asset on its chosen chain through one embedded, non-custodial flow.

Enable users to pay with the assets they already own, regardless of which supported token or chain they are on. Avail Nexus can combine eligible balances from one or multiple sources, convert them into the required settlement asset (such as stablecoins), and deliver the exact amount to the app or recipient on the correct chain. Routing, swaps, and gas are coordinated in the background, removing the need for users to bridge funds, switch networks, or acquire gas before paying. Suitable for in-app purchases, marketplaces, fintech products, gaming, and other crypto payment experiences.

The FastBridge Widget lets users bridge and swap stablecoins and other tokens from one or multiple source chains to a single destination in one transaction. It consolidates fragmented balances, identifies an efficient route, and handles swaps, cross-chain execution, and gas without requiring users to switch networks or hold native gas tokens on every chain.

Accept crypto payments through an embeddable QR-based pay-in widget. Users scan a QR code or send funds to a deposit address from a supported external wallet or exchange. Avail then coordinates any required swap, bridging, routing, and gas to deliver the configured settlement asset to the app or recipient on the correct chain. This allows apps to accept stablecoins and other tokens from a broader range of wallets and chains through a familiar payment flow, making it suitable for crypto checkout, invoices, and both online and in-person payments.
