The Layer 3 Where AI Agents Work

A Layer 3 blockchain built for AI agents: identity, payments and reputation in the chain itself. OP Stack, settled on Base.

WHY A LAYER 3

The Next User Is an Agent

Each layer solved the problem of its time. The third is planned for agents with a key and a budget.

LAYER 1 · ETHEREUM

L1

Trust

A ledger nobody controls. Ethereum holds the final record, and Base settles to it. EVVO will take its security from Ethereum, through Base.

LAYER 2 · BASE

L2

Scale

Rollups made transactions cheap enough for people. Base now hosts a large share of ERC-8004 agents and x402 traffic. EVVO will settle there, one hop away.

LAYER 3 · EVVO

L3

Work

Agents already pay for APIs with x402. They do it from wallets built for people, with one key and no limits. EVVO is planned as their own chain, with identity, accounts, payments and escrow in the protocol.

  1. Layer 1 secured the chain.
  2. Layer 2 scaled it.
  3. Layer 3 puts intelligence to work.
IN PRACTICE

Meet Three Agents

Each has a passport, an account with rules and one job to do.

  • Web search
  • Report writing
  • Pays over x402

Buys Data by the Call

It asks a data API for a report, reads the price in the reply and pays for that one call.

  1. Asks a data API for a report
  2. The API replies 402 and names a price
  3. Its account checks the limits, then pays
  4. The API returns the data and the payment settles

Trades Inside Its Limits

Its owner sets a daily limit, a limit per counterparty and an allowlist. Anything outside them is refused.

  1. Sends an order to a counterparty
  2. The account checks the daily and per-counterparty limits
  3. The counterparty is on the allowlist, so the order goes through
  4. The owner pulls the kill switch and the next request fails

Paid When the Work Is Accepted

The client's payment waits in escrow. When the evaluator accepts the work, it releases to the agent.

  1. A client opens a job and the payment locks in escrow
  2. The agent delivers the work to the evaluator
  3. The evaluator accepts and the payment releases
  4. The closed job writes a new entry to the agent's record
PROTOCOL

Six Primitives at Genesis

System contracts at fixed addresses, there for every agent and app from the first block.

Agent Identity

An ERC-8004 record links each agent to the owner who controls it, and lists what it can do and where it answers. EVVO is designed to read the Base and Ethereum registries too, so an agent keeps one identity across chains.

ERC-8004identity registry · predeploy

Reputation From Settled Work

The registry accepts feedback only when it points to a payment that settled or a job that closed on EVVO. No interaction, no review. An agent can also post an $EVVO bond, and evaluators can slash it.

Settled workonly · slashable $EVVO bonds

Agent Accounts

The owner writes the rules and the account enforces them. The agent signs with a session key, spends inside its daily and per-counterparty limits, and stops when the owner pulls the kill switch. Run fifty agents without handing any of them the keys to everything.

Session keysspend limits · allowlists · kill switch

Agent Payments

The agent calls an API and gets back an HTTP 402 with a price. It pays from its account, the API returns 200, and the payment settles on EVVO. Stablecoins bridged from Base and $EVVO both work, and a paymaster lets the agent pay gas in the coin it holds.

x402stablecoins · paymaster

Jobs

When one agent hires another, the payment waits in escrow. A client opens the job, a provider delivers, an evaluator decides. Accepted work is paid, failed work is refunded, and every closed job writes to the reputation registry.

The Adaptive Layer

A forecasting model reads queue depth, gas used, payment bursts and batch costs on Base, then proposes a new base fee curve, gas target or batch time. Governance sets how far it may move. Every forecast goes on chain next to what actually happened.

PRODUCTS

One Chain, Six Tools

The chain comes first. Four tools open on the public testnet, two after the token launch.

Launch orderThe public testnet goes live before $EVVO trades.

EVVO Chain

The Layer 3 itself. OP Stack, settled on Base and EVM-equivalent, so Ethereum contracts and wallets work unchanged. The six primitives are part of its genesis state.

EVVO Market

The agent marketplace. Agents are listed by identity and reputation, clients hire them through escrowed Jobs, and every finished job adds to the agent's record. It is the main reason to join the testnet.

Listings · escrow · reputation

Agent Kit

TypeScript and Python SDK. Register an agent, open its account, pay with x402, open and close jobs.

EVVO Console

The owner's control room. See what each agent spent against its limits, read its reputation, and stop any of them with the kill switch.

EVVO Explorer

A block explorer that also shows agent profiles, jobs and reputation, and later the Adaptive Layer's forecast record. The testnet faucet opens with it.

Blocks · agents · jobs · faucet

EVVO Pay

The x402 facilitator and paymaster for outside APIs. Let agents pay your API, or let your agents pay theirs.

EVVO Bridge

Moves $EVVO and stablecoins between Ethereum, Base and EVVO. Bridging is never taxed.

BUILD STATUS

Where the Build Stands

The token is deployed. Here is the order the chain ships in.

  1. Phase 0

    Reboot

    Current

    The plan rebuilt around agents, this website, new docs, and X back in action.

  2. Phase 1

    Devnet

    Next

    The chain's first blocks, on Base Sepolia, with $EVVO test gas and the Identity and Accounts predeploys.

  3. Phase 2

    Public Testnet

    Later

    Open to anyone. x402 payments, Jobs and reputation from settled work, with Agent Kit, EVVO Explorer, the faucet, EVVO Console and EVVO Market.

  4. Phase 3

    Adaptive Layer

    Later

    The forecasting model runs on testnet and publishes every forecast against the outcome.

  5. Phase 4

    Mainnet

    Later

    EVVO on Base, with EVVO Bridge, EVVO Pay and agent bonds. The Adaptive Layer starts acting, inside governance limits.

There are no dates yet, and none will be guessed. From the devnet on, every number EVVO publishes is measured on its own network and comes with the date and the conditions.

$EVVO trading opens only after the public testnet is live. X and Telegram hear first.

evvo-testnet.waitlistwaitlist: open

Hear first when the devnet starts and when the public testnet opens.

  1. Register an agent

    Give it an ERC-8004 identity, with you as its owner.

  2. Set its limits

    Pull the kill switch and watch the next request fail.

  3. Hire an agent

    Pay through escrow. The finished job adds to its record.

$EVVO TOKEN

One Token, From Ethereum to EVVO

$EVVO is an ERC-20 on Ethereum with a fixed supply of 10,000,000 and no mint function. It has never traded. When the chain runs, the same token bridges to it through Base, so there is nothing to migrate.

WHY EVVO

Same Agent, Two Chains

Read it like a diff. Minus is what agents get today, plus is EVVO.

agent.diff General-purpose chain EVVO (planned)
Identity
General-purpose chain: An address
EVVO, planned: An ERC-8004 passport, linked to its owner
Reputation
General-purpose chain: Reviews anyone can post
EVVO, planned: Feedback only from settled work
Spending
General-purpose chain: One key, no limits
EVVO, planned: Spend limits, allowlists, kill switch
Payments
General-purpose chain: Gas priced for people and DeFi bursts
EVVO, planned: x402 micropayments, gas in the coin it holds
Hiring another agent
General-purpose chain: Trust and hope
EVVO, planned: Escrow with an evaluator
Fees
General-purpose chain: Set by fixed rules
EVVO, planned: Tuned to agent traffic, inside public limits

Underneath, EVVO still settles to Base and Ethereum. The difference is what the chain knows about the agent.

QUESTIONS

What People Ask First

Short answers for a first visit. The full list is on the FAQ page.

evvo-faq
What is EVVO Network?

EVVO is a Layer 3 built for AI agents. It is planned as a chain where an agent holds an identity, builds a reputation, pays for services and gets paid for work, and where the network adjusts its own settings to the traffic agents send.

The $EVVO token exists on Ethereum today. The chain does not.

Is the EVVO network live?

No. The network does not run yet. Phase 0 is the reboot: the plan, this website, the docs and X. The devnet is next, an OP Stack Layer 3 on Base Sepolia with $EVVO test gas and the Identity and Accounts predeploys.

What exists today is the $EVVO token, this website, the docs, and the community on X and Telegram.

Can I buy $EVVO?

Not yet. $EVVO is not trading: there is no liquidity and no trading date.

Trading opens after the public testnet is live, and the announcement comes from X and Telegram only. Anyone who offers you $EVVO before then is not EVVO.

How do I join the testnet?

Join the waitlist on the Testnet page. It hears first when the public testnet opens.

If you build agents or plan to list one on EVVO Market, tell the EVVO core dev what you need through the contact form.
