Smart Recipes

Cross-chain DeFi deposits in one call. Your user holds USDC on Base. Your app deposits it into a vault on Arbitrum. One quote, one signature. You write no bridge, vault, or relayer code.

const quote = await sr.morpho.deposit({
  owner: user,
  amount: "100",
  token: TOKENS.USDC,
  srcChainId: 8453,      // funds on Base
  into: vault,           // vault on Arbitrum
});
// user signs one transfer, funds arrive in the vault

Without it you would build a bridge integration, per-protocol deposit calldata, a relayer to execute on the destination chain, cross-chain status tracking, and a recovery path for each failure. Smart Recipes replaces all of it: the server quotes the route, a Smart Routing Address (SRA) executes it, your user signs a single transfer.

Three things worth knowing up front:

Non-custodial. Funds move through permissionless contracts. ZeroDev never holds them, and only the owner can recover a failed deposit.
No protocol maintenance. Vault lists, routes, and calldata live server-side. A new vault needs no SDK update.
Any wallet stack. Each quote carries both a plain transaction batch and an ERC-4337 user operation. The SDK has no signer and no runtime dependencies.

There are two, and one of them is currently off:

Recipe	Call it with	Status
Deposit into a vault	`sr.aave.deposit`, `sr.morpho.deposit`, `sr.fluid.deposit`, `sr.yearn.deposit`, `sr.erc4626.deposit`, or `sr.depositIntoVault`	Available
Withdraw from a vault	`sr.withdrawFromVault`	Available, same-chain only
Bridge and swap	`sr.bridgeAndSwap`	Disabled, always rejects

The five deposit facades are one recipe with the protocol pre-bound. sr.depositIntoVault is the same engine with protocol passed explicitly. Everything else in the SDK is discovery, status, and recovery around those calls.

Smart Recipes performs no swaps of its own. A deposit whose funding token differs from the vault asset still works: SRA converts on delivery as part of its own route. See Recipes.

Quickstart: a first deposit in about 20 lines
Recipes: every parameter, deposits through recovery
How it works: the flow, the custody model, failure behavior
Reference: the Quote type, every method, every error code
