step 4Your app tracks delivery to the Gateway balance
Example: swap and deposit with a price limit
Compare available pool prices when the transaction runs.
Swap only if the output meets your minimum.
Deposit the received tokens into a lending market.

Build the workflow
your application needs.

Start with the Routes API + CLI for transfers or the Sauce SDK for onchain programs. Combine the capabilities below to build your application’s workflow. Compare integrations

Transfers

Routes API + CLI

Send or swap stablecoins between supported chains with the Routes API or CLI.

  • Discover chains and tokens, verify a quote, fund it, and track the intent
  • Read the API guide for funding methods, errors, and lifecycle handling
  • Use the CLI for an interactive transfer workflow
Read the docs
Routes API workflowv1
1. Discover supported chains and tokens
2. Quote the requested transfer
3. Verify the signature and execution data
4. Fund with the selected method
5. Track the intent lifecycle
 
Onchain programs

Sauce SDK

Build onchain payment, trading and treasury programs with the TypeScript library, command-line tool or AI agent tools.

  • Read live balances and prices, choose actions, and enforce the conditions you set
  • Compile and simulate before signing a transaction
  • Use SauceScript to combine contract calls in one transaction on one chain
Read the docs
pay.sauce.tsSauceScript
function main(to: Address, amount: Uint256)
  require(pot.USDC >= amount, “not enough USDC”);
  USDC.transfer(to, amount);
