contract.Client and rpc.Server. - Framework Patterns: Ready-to-use React hooks, components, and Next.js App Router setup with proper environment configuration for Testnet and Mainnet. - Use Case: You are building a Next.js app that lets users connect Freighter, read a token balance from a Soroban contract, and submit a payment — this Skill gives you the SDK initialization, wallet hook, contract client, and submission code end to end. ## Quick Start Use the dapp skill to build a React component that connects a Freighter wallet and invokes a Stellar smart contract method.High-intent search queries and answers about installing and using this skill.
Use @stellar/freighter-api with isConnected, requestAccess, and getAddress to detect the extension and prompt the user for access. Wrap the calls in a React hook that tracks connection state, address, and network, then expose a sign function using signTransaction with the correct network passphrase.
Use contract.Client.from() from @stellar/stellar-sdk with the contract ID, RPC URL, network passphrase, and a signTransaction function. Each method returns an AssembledTransaction you can preview via simulation or apply on-chain with signAndSend, without building ScVal arguments by hand.
Freighter API connects only to the Freighter browser extension, while Stellar Wallets Kit supports multiple wallets through a single static interface. Wallets Kit v2 is distributed on JSR as @creit-tech/stellar-wallets-kit and uses authModal() for wallet selection and address retrieval.
No, SDK v16 requires Node.js 22 or later and produces an EBADENGINE warning on older versions. It is ESM-first, uses native fetch instead of axios, and folds @stellar/stellar-base into the main package, so you should uninstall the separate base package.
Submissions fail from network passphrase mismatches, unfunded accounts, or missing simulation before signing. Use rpc.prepareTransaction to simulate and assemble fees and auth, then rpc.pollTransaction to track confirmation instead of a hand-rolled polling loop.
Yes, fee sponsorship via the OpenZeppelin Relayer channels service submits transactions using Stellar's fee bump mechanism so users need no XLM. A hosted testnet instance is available, and production deployments self-host via Docker.
