# Quickstarts

> Build your first Eco transfer, deposit flow or Sauce program, then adapt a complete example for your application.

Choose a quickstart for what you want to build. Start with a transfer, a deposit flow or a Sauce program, then adapt a more detailed example. Each guide lists the prerequisites and explains what to check before sending transactions.

If you are still choosing an approach, explore the [developer platform](https://docs.eco.com/platform/overview.md). The **Sauce SDK** tab contains its tool and language references; the **Sauce SDK** section here contains the hands-on walkthroughs and examples.

## Start with one working flow

| You want to… | Start here |
| - | - |
| Send a transfer from your terminal | [Make your first transfer](https://docs.eco.com/quickstarts/first-transfer.md) |
| Add cross-chain transfers to an application | [Integrate the Routes API](https://docs.eco.com/quickstarts/integrate-routes-api.md) |
| Combine onchain actions in a program | [Run your first Sauce program](https://docs.eco.com/quickstarts/sauce/first-program.md) |
| Route a deposit to another chain | [Route Base deposits to Solana](https://docs.eco.com/quickstarts/auto-route-deposits.md) |
| Build with a coding agent | [Build with AI agents](https://docs.eco.com/get-started/build-with-agents.md) |

## Routes API and CLI

| Guide | What you build or learn |
| - | - |
| [Send USDC across chains](https://docs.eco.com/quickstarts/send-usdc-cross-chain.md) | A transfer from quote verification through funding and delivery tracking. |
| [Verify quotes before funding](https://docs.eco.com/quickstarts/verify-quotes.md) | A TypeScript function that checks a quote, its signature and its funding transaction. |
| [Build a browser wallet transfer app](https://docs.eco.com/quickstarts/wallet-transfer-app.md) | A React app that connects a wallet, verifies a quote, funds a transfer and tracks delivery. |
| [Cross-chain treasury rebalancing](https://docs.eco.com/quickstarts/treasury-rebalancing.md) | A balance policy, transfer submission flow and reconciliation plan. |

## Deposit and payout

| Guide | What you build |
| - | - |
| [Route Base deposits to Solana](https://docs.eco.com/quickstarts/auto-route-deposits.md) | A Base USDC deposit address associated with a Solana recipient. |
| [Gasless USDC deposits into Circle Gateway](https://docs.eco.com/quickstarts/gasless-gateway-deposit.md) | A deposit flow funded with an ERC-3009 signature. |

## Sauce SDK

Start with [your first Sauce program](https://docs.eco.com/quickstarts/sauce/first-program.md) to compile and simulate a USDC payment. Then explore [Sauce SDK quickstarts](https://docs.eco.com/quickstarts/sauce/overview.md) for complete payment, swap, lending and portfolio examples on EVM chains and Solana.

Each example runs on one chain. To understand how a program can fit into a cross-chain flow, see [Program your route](https://docs.eco.com/programmable-transactions/overview.md).

## Solvers

Read the [solver integration overview](https://docs.eco.com/quickstarts/solvers.md), then follow [Become a solver](https://docs.eco.com/quickstarts/become-a-solver.md) to prepare quoting, registration, fulfillment and settlement.

## Next steps

* [Set up your integration](https://docs.eco.com/get-started/setup.md): check credentials, dependencies and environment requirements.
* [Build with AI agents](https://docs.eco.com/get-started/build-with-agents.md): connect documentation and skills to your coding agent.
* [Routes API reference script](https://docs.eco.com/routes-api/agent-integration.md): inspect a complete TypeScript transfer flow.
