Amplify Earn Developers

Integrate stablecoin yield via the Amplify SDK, direct contract calls, or the REST API.

Three integration paths into Amplify Earn. Pick the one that matches your stack.

Amplify SDK

TypeScript / JavaScript client. Calls the REST API for you and returns ready-to-submit transaction calldata.

Direct Contract

Any language. Call the on-chain contracts directly using your own ABI tooling.

API Calldata

Any language. Hit the REST API directly — it returns ABI-encoded calldata your signer submits.

	SDK	Direct Contract	API Calldata
Languages	TypeScript / JavaScript	Any EVM-capable language	Any language with an HTTP client
Setup	pnpm add @paxoslabs/amplify-sdk	RPC + contract addresses + ABI	API key + HTTP client
Calldata source	SDK calls API on your behalf	Encode locally with viem/web3/etc.	REST API
Best for	Web + Node.js apps	Mobile, non-JS backends, bespoke clients	Server builders, custodial wallets, multisig
