The Problem
AI Agents Don't Fit Human Wallets
Today, giving AI access to capital means:
Opening multiple small wallets
Pre-funding isolated accounts
Manually approving transactions
Or worse -- exposing private keys
This fragments liquidity, increases operational friction, and makes autonomous execution nearly impossible.
Wallets assume a human signer. AI needs something different.
The Shift
From Transaction Signing → To Rule Signing
Echo introduces a new primitive: Instead of signing every transaction, you sign execution rules.
Asset scope
Which tokens can be used
Spending limits
Max per-tx and daily caps
Time boundaries
Active execution windows
Protocol permissions
Allowed contract targets
What Echo Is
An Agent Native Smart Account Protocol
Built for AI Agent Builders.
Built for autonomous systems.
Built for what comes next.

How Echo protects AI payment execution
Step 1
AI Agent Proposes
Rebalance treasury portfolio
Send 100,000 USDC
to StrategyContract
AI can propose actions, but should not execute them.
Step 2
Echo Verifies
Policy Check:
Max: 50,000 USDC
Target: StrategyContract
Window: 24h
Step 3
Result
Transaction Blocked
Reason: Amount exceeds policy limit
Echo checks whether the action stays within user-defined boundaries.
Who It's For
If you are building agents, you need a native capital layer.
AI Agent Builders
Give your agents real execution power -- safely.
On-Chain Strategy Developers
Deploy autonomous trading, payment, or subscription agents with enforceable limits.
Proto-ToC Power Users
Experiment with AI-managed capital under bounded rules.
How It Works
Four steps. No custody. Full auditability.
Sign Rules Once
User defines and signs execution rules
Generate Authority
Echo creates rule-bound execution authority
AI Executes
Agent transacts within defined constraints
On-Chain Audit
Every action is verifiable and auditable
Why This Matters
AI autonomy is increasing. Capital access must evolve with it.
Human wallets cannot scale to autonomous systems. Echo provides the missing layer between AI and on-chain capital.
Wallets are for humans.
Echo is for AI.
