How it works

Ditto packages account-abstraction primitives into composable building blocks. Drop in smart accounts, scoped session keys, gas sponsorship, and transaction batching — then wire in automated DeFi actions secured by a decentralized execution network. Your users keep custody; your team skips months of wallet and keeper infrastructure.

  • Smart accounts & session keys built in
  • Gas abstraction & batching, paymaster⁠-⁠ready
  • Non-custodial — users keep key control

Why teams build smart-wallet apps on Ditto

    • Account abstraction out of the box

      Smart accounts, session keys, and bundler/paymaster support without standing up your own AA stack.

    • Gasless & batched transactions

      Sponsor gas for users and batch multiple calls into a single, seamless action.

    • Scoped session keys

      Grant precise, revocable permissions so apps and automations act within strict limits.

    • Embedded DeFi automation

      Schedule and trigger swaps, staking, and rebalancing directly inside your product.

    • Non-custodial by design

      Users retain key control; Ditto never holds funds.

    • Multi-chain native

      One integration across Ethereum, Base, Arbitrum, Polygon, and Optimism.

    • Policy controls & audit trails

      Role-based approvals, constraints, and verifiable execution records.

    Key Features

    • Smart accounts & session keysERC-4337 smart accounts with scoped, revocable session keys for safe delegation to apps and automations.
    • Gas sponsorship & paymastersAbstract gas away from users — sponsor fees or let users pay in tokens via paymasters.
    • Batching & automationBundle multiple operations and automate recurring on-chain actions with time, event, or on-chain triggers.
    • Embedded DeFi actionsSwap, stake, transfer, and rebalance from inside your app, executed by a decentralized network.
    • One integration, many chainsBuild once and deploy across all supported EVM networks.

    Smart Wallets & DeFi Integration FAQ

    Talk to Sales
    • What is a smart wallet / account abstraction?

      Account abstraction (ERC-4337) turns a user's wallet into a programmable smart account — enabling gas sponsorship, batched transactions, session keys, and automated actions that aren't possible with a standard EOA.

    • Is Ditto custodial?

      No. Ditto is non-custodial — users retain control of their keys and funds. Session keys grant only scoped, revocable permissions.

    • Which chains are supported?

      Ethereum, Base, Arbitrum, Polygon, and Optimism, from a single integration.

    • How are session keys kept secure?

      Session keys carry explicit, limited permissions and can be revoked at any time, so apps and automations can only do exactly what you authorize.

    • Can I sponsor gas for my users?

      Yes. Paymaster support lets you sponsor gas or allow users to pay fees in tokens, removing a major onboarding hurdle.

    • How long does integration take?

      Most teams integrate core smart-wallet flows in days using the SDK's prebuilt building blocks, instead of months on custom infrastructure.
