WDKworkflows

Build gasless USD₮ workflows

A visual, no-code automation platform on Tether's Wallet Development Kit. Monitor onchain state, trigger transactions, and pay every fee in USD₮. Never hold a native gas token.

Everything you need to automate

A complete toolkit for USD₮ workflows, from a first gasless send to scheduled payouts and protocol calls.

Gasless USD₮

Paymasters settle gas in USD₮. Native ETH can stay at zero.

Visual automation

Triggers, conditions, WDK execution, settlement, and alerts on one canvas.

Quote before execute

See the USD₮ fee on screen before any UserOperation is submitted.

WDK ERC-4337

One smart account for wallet and protocol steps. No second signer.

Open source

Fully auditable code. No vendor lock-in. Fork and run your own instance.

Self-custodial

You control the seed. The app never takes custody of your keys.

Agent ready

The same board a person builds by hand can be drafted from a prompt.

Protocol steps

LI.FI, USDT0, Aave, Morpho, and Symbiosis through the same paymaster.

Simple, powerful API

Every onchain step is a WDK quote, then a WDK execute. The canvas does not wrap one helper while the rest of the app uses a different signer.

  • Unified quote-then-execute across wallet and protocol steps
  • Full TypeScript types on WDK quote and transfer calls
  • Fee shown in USD₮ before any UserOperation is submitted
  • Same ERC-4337 account for send, swap, lend, and bridge
WDK Playground
import { WDK } from "@tetherto/wdk"

const account = await wdk.getAccount()
const quote = await account.quoteTransfer({
  token: "USDT",
  to: recipient,
  amount: "10",
})
// feeUsdt is ready before you sign
await account.transfer(quote)

Modular by design

Pick the building blocks you need: wallets, swaps, bridges, lending, and alerts. Compose them into a workflow that never asks for a native gas token.

Triggers

Start a run by hand, on a schedule, from a webhook, or from an event.

Conditions

Branch on balances, quotes, and onchain state before you spend.

Wallet and paymaster
