Best-pool swap example

Read quotes from two configured pools.

Compare the output amounts.

Execute through the selected pool.

singleOne program reads configured contracts and selects a path

atomicAn uncaught revert rolls back the execution transaction

deployCompile a program and execute it through the Sauce runtime

Quickstart guides

Make your first transfer

Preview and publish a USDC transfer with the CLI wizard.

Send stablecoins across chains

Request a quote, verify it, fund an intent, and track its status.

Accept Base USDC for Solana

Create a deposit address for a Solana recipient and fund it with Base USDC.

Gasless deposits into Circle Gateway

Use a supported signature-based funding method for a Gateway deposit.

Become a solver

Implement two quote endpoints, register, fulfill intents, earn per-intent rewards.
