# Fundable SDK

`@fundable/sdk` is the TypeScript integration layer for Fundable Protocol. It gives applications a typed, high-level API for token streams while keeping chain-specific transaction handling inside adapters.

Stellar is the first production adapter. The shared model is intentionally chain-neutral so an EVM adapter can be added without redesigning application code.

## What you can build

* create and manage continuous Flow streams;
* create NFT-backed Flow and Lockup streams through the Router;
* read and transfer Stream NFTs;
* prepare bounded Paymaster forwarding transactions;
* use exact `bigint` token amounts across browser and server applications.

## Start here

1. Follow [Getting started](/docs/getting-started.md) to install and configure the SDK.
2. Review [configuration](/docs/configuration.md) and [transaction signing](/docs/transactions.md) before enabling writes.
3. Run the [example implementations](/docs/examples.md) against your deployment.
4. Read [Multichain architecture](/docs/multichain-architecture.md) to understand the stable core and chain-adapter boundary.
5. Use [Router, Stream NFT, and Paymaster](/docs/router-paymaster.md) for the protocol composition contracts.
6. Review [Generated bindings](/docs/generated-bindings.md) when validating contract and SDK release provenance.

Review [Troubleshooting and versioning](/docs/troubleshooting-and-versioning.md) before upgrading between SDK releases.
