Atto documentation

Atto is feeless digital cash for agents and humans. Start with an integration, try a wallet, or look inside the protocol.

Quick Start​

Integrations

Build with Atto

Connect an AI agent, use the CLI, automate with N8N, or build with Commons.

Read the guide How it works

Explore the protocol

Understand account chains, representative voting, and the two sides of a payment.

Read the guide Get started

Create a wallet

Choose a wallet and learn how to receive your first payment.

Inspect the data

Explore amounts, addresses, blocks, and network data without building an integration first.

Read the guide

Already have a wallet? Try the faucet for a small amount, or open the explorer to inspect accounts and transactions.

Core Documentation​

Whitepapers​

Read the MiCA Crypto-Asset Whitepaper or the separate technical explanation of Atto's consensus, account-chain model, supply, and security assumptions.

  • Open Representative Voting (ORV) consensus
  • Account-chain architecture
  • Anti-spam mechanism via lightweight PoW
  • Fixed supply of 18B coins (no new minting)
  • Representative voting rather than competitive proof-of-work mining for consensus

Token Distribution​

How Atto enters circulation through the faucet, Folding@Home mining, staking rewards, and contribution rewards. Rates and eligibility follow the current reward policy. The Growth Stability Index (GSI) adjusts configured rates for distribution programmes that use it.

  • Faucet for new users
  • Folding@Home mining for research contributors
  • Staking rewards for eligible accounts delegated to participating voters
  • Contribution rewards for useful work

Distribution and Reward Routes​

Reward availability

Reward eligibility, rates, and timing depend on the current rules for each route and may change.

Faucet

Claim a small amount of Atto and try payments from your own wallet.

Key Features​

Instant Transactions​

Atto does not wait for a shared block queue. Transactions are processed as they reach the network, and the current median/P50 confirmation time is about 147 ms. A transaction may be treated as confirmed when it satisfies the network's then-current voting rules. Confirmation and recovery still depend on software, voting-weight distribution, connectivity, infrastructure, and operating conditions.

Zero Fees​

Atto has no protocol transaction fee. If you send 1 ATTO, the recipient receives 1 ATTO. That makes small payments, tips, faucets, and everyday transfers practical instead of being eaten by fixed network fees.

Lightweight Consensus​

Consensus is voting, not mining. Each transaction includes a small proof-of-work to slow spam, but representatives decide confirmation through Open Representative Voting (ORV). The result is a payment network that stays lightweight without turning security into an energy race.

Secure & Decentralized​

Each account controls its own chain of transactions, and conflicting updates are resolved by representative votes. Delegation assigns representatives voting weight without transferring custody of the account's funds.

Scalable​

Atto uses account chains instead of one shared block queue. Independent accounts can move in parallel, so the network is not forced to serialize every payment through a single global block.

Use Cases​

  • Micropayments for pay-per-use services, content tips, and in-app purchases
  • Retail payments where checkout needs fast confirmation and no network fee
  • Remittances where the sender should not lose value to fixed transfer fees
  • Machine-to-machine payments for small automated transfers
  • Gaming balances, item trades, donations, and tips

How Atto Works​

Open Representative Voting (ORV)​

Instead of mining blocks, Atto holders delegate voting weight to representatives they trust. Representatives vote on the validity of transactions and confirm the winning state.

Account Chains​

Each account has its own chain of transactions. That lets independent accounts move in parallel instead of waiting for a single global block queue.

Anti-Spam Protection​

To prevent spam without fees, Atto requires a small proof-of-work for each transaction. The work is lightweight for normal use but makes bulk spam more expensive.

Fixed Supply​

The full 18 billion ATTO supply was created at genesis. No new coins can be minted; distribution programs move that existing supply into circulation over time.

Get Involved​

Atto needs practical contributions, especially work that helps people run, use, explain, or integrate the network.

  • Improve the node, wallet, or libraries
  • Write docs, tutorials, and integration notes
  • Test releases and report bugs
  • Help users on Discord
  • Create useful guides or technical content
