Quickstarts - Eco Docs

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. 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
Add cross-chain transfers to an application	Integrate the Routes API
Combine onchain actions in a program	Run your first Sauce program
Route a deposit to another chain	Route Base deposits to Solana
Build with a coding agent	Build with AI agents

Routes API and CLI

Guide	What you build or learn
Send USDC across chains	A transfer from quote verification through funding and delivery tracking.
Verify quotes before funding	A TypeScript function that checks a quote, its signature and its funding transaction.
Build a browser wallet transfer app	A React app that connects a wallet, verifies a quote, funds a transfer and tracks delivery.
Cross-chain treasury rebalancing	A balance policy, transfer submission flow and reconciliation plan.

Deposit and payout

Guide	What you build
Route Base deposits to Solana	A Base USDC deposit address associated with a Solana recipient.
Gasless USDC deposits into Circle Gateway	A deposit flow funded with an ERC-3009 signature.

Sauce SDK

Start with your first Sauce program to compile and simulate a USDC payment. Then explore Sauce SDK quickstarts 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.

Solvers

Read the solver integration overview, then follow Become a solver to prepare quoting, registration, fulfillment and settlement.

Next steps

Set up your integration: check credentials, dependencies and environment requirements.
Build with AI agents: connect documentation and skills to your coding agent.
Routes API reference script: inspect a complete TypeScript transfer flow.
