Give users a single stablecoin balance that works everywhere. Abstract away chains, gas tokens, and network switching—users sign once and spend anywhere.

​
Perfect For

Consumer Applications: Eliminate onboarding friction—users connect once and can immediately interact with your app from any chain. DeFi Protocols: Accept deposits from any chain without maintaining infrastructure everywhere. Users see your protocol as a single destination. Payment Platforms: Enable seamless payments where users never think about which chain their funds are on.

​
What This Enables

Universal Balance View: Users see one total balance across all chains and stablecoins, normalized to a single number. The system maintains the real-time view and handles all complexity underneath. Automatic Source Selection: When users spend, the system automatically selects the optimal source chain and token based on fees, speed, and user preferences. Gasless Execution: All transactions are paid in stablecoins. Users never need to acquire native gas tokens for destination chains. Flexible Permissions: Grant controlled spending rights with Permit3: set amount limits, time constraints, allowed actions, and automatic expiration.

​
What This Solves

​
The Multi-Chain Fragmentation Problem

Traditional Experience:
  • User has USDC on Ethereum
  • Wants to use your Base protocol
  • Must: switch networks → find bridge → bridge funds → acquire BASE for gas → switch back → finally use your app
  • Most users abandon at step 2
With Eco Abstraction:
  • User signs one transaction
  • Funds automatically route from Ethereum to Base
  • Gas paid in USDC
  • Transaction executes immediately
  • User never left your interface

​
The Permission Problem

Traditional ERC-20 Approvals:
  • Per-contract, per-chain permissions
  • Users must approve on every chain
  • No expiration or granular control
  • Either full approval or none
With Permit3:
  • One signature grants controlled spending
  • Set amount limits, time limits, specific actions
  • Works across all chains simultaneously
  • Automatic expiration and easy revocation

​
Key Features

​
Global Balance View

Collapse all stablecoin holdings across chains into a single spendable balance. Users see total purchasing power, not fragmented chain-specific amounts.

​
One-Click Actions

Any onchain operation becomes a single signature. Deposit into Base protocol from Ethereum balance with one click—no manual bridging.

​
Permit3 Authorization

More flexible than traditional ERC-20 approvals:
  • Set specific amount limits
  • Define time duration for permission
  • Specify which actions are allowed
  • Works across all chains with one signature
  • Automatic expiration and easy revocation

​
Cross-Chain Spending

Users can spend from any chain where they hold stablecoins:
  • System automatically bridges if needed
  • Swaps to required token if needed
  • Executes destination action atomically
  • All-or-nothing execution
