React Native SDK
A collection of 100+ React hooks and React Native UI components for your web3 mobile apps, for any EVM-compatible blockchain.
Connect to user’s wallets, interact with smart contracts, sign messages, and utilize common standards such as tokens, NFTs, marketplaces; all with built-in caching, RPC URLs, IPFS gateways, and more.
React Native SDK is open-source; view and contribute to its source code on GitHub.
How It Works
The React Native SDK uses React Query under the hood to expose a collection of query and mutation hooks, each with built-in caching, query invalidation, query retries, and more.
Each hook (except for wallet/network management) wraps some functionality of the TypeScript SDK, which are made available as either a query hook to read data, or as a mutation hook to write transactions to the blockchain.
When mutations are called (when a user executes a transaction), query invalidation is automatically triggered to update the relevant queries that depend on the data that was changed. For example, when minting a new NFT, queries that view information about NFTs are re-fetched to load the new NFT automatically.
Queries
All query hooks are used to read data from the blockchain, smart contracts, a user’s wallet, etc.
Each one comes with some helpful properties to create a powerful user experience:
data
- The data returned from the query (e.g. the NFTs of a contract).isLoading
- Whether the query is currently loading.error
- The error returned from the query, if any.
Mutations
Mutations are used to write data to the blockchain when a transaction is required.
They require a wallet to be connected, and by default, are executed from the currently connected wallet.
Each mutation comes with similar properties to queries:
mutate
- The function to execute the mutation (e.g. mint a new NFT).mutateAsync
- The function to execute the mutation, but returns a promise (allowingawait
to be used).isLoading
- Whether the mutation is currently executing.error
- The error returned from the mutation, if any.
Upon execution of a mutation, the relevant queries are automatically invalidated to fetch the latest data.
