FAQ
Frequently asked questions.
Short answers to the questions people ask most about how Summo works: custody and safety, recovery, fees, payments, trading, and getting started. Each topic has a full page in this section.
01About Summo
What is Summo?
Summo is a self-custodial mobile wallet for digital markets: one app to hold and send assets, pay in stores, trade, and earn. You control your own funds, and Summo can never move them on its own.
Is Summo an exchange?
No. Summo is a self-custodial wallet. Your assets stay in your own account, controlled by your keys, and you sign your own transactions. Trading connects to outside liquidity and partner venues, but Summo never holds your funds the way an exchange does.
Does Summo charge a monthly or account fee?
No. There is no monthly or account fee. You pay network fees on transactions, which can be paid in several ways, and a service fee on certain actions. Every option and its cost is shown before you confirm.
02Custody and keys
Is Summo custodial? Who controls my money?
Summo is non-custodial. Your account is a smart account secured by three keys under a two-of-three threshold: you control two of them, both derived from your recovery phrase, and Summo holds one. Summo can never move your funds on its own, and with your recovery phrase you can always move funds without Summo.
What is the co-signer?
The co-signer is the one key Summo holds. It adds a second signature only after checking a transaction against your account security policy. As one key of three, it can never move funds by itself, and it cannot stop you from moving funds with the two keys derived from your recovery phrase.
Can Summo freeze or take my funds?
Summo cannot take your funds, because it holds only one of three keys. Summo can freeze an account, for example after you report a lost phone, and while an account is frozen its co-signer signs nothing. The co-signer also declines specific transactions, such as a payment to a destination on the sanctions and scam blocklist or one above a spending limit you set. A freeze or a declined signature never moves funds, and with your recovery phrase you can always move funds without Summo.
Do I need a seed phrase? How do I sign in?
You sign in with Apple, Google, or email, with no password to remember. Your keys are generated on your device at sign-up, so the account is self-custodial from the start. A recovery phrase is created on the device and secured in its hardware for you to back up in writing.
03Security and recovery
Is Summo safe?
Summo is non-custodial, and its checks on the money path are built to block a risky transaction rather than let it through. Protections include two-of-three custody, an encrypted on-device recovery phrase, a policy co-signer that screens every payment made through Summo, guardians, sanctions and scam-address screening, look-alike-address defense, and code that reaches production only through hardware-signed, verified releases.
What happens if I lose my phone?
Your written recovery phrase restores the account on a new device at any time, independently of Summo. If you have added guardians, they can also help you recover access.
What if I lose my recovery phrase as well?
If you have set up guardians, trusted contacts you choose, they can help you regain access even without the written phrase. A recovery starts on your new device and completes once the required number of guardians approve it, each after confirming the request with you directly. Without guardians, the written phrase is the only way to restore the account on a new device.
What are guardians?
Guardians are trusted contacts you invite. They approve requests made from your account, such as loosening a spending limit or restoring access on a new device, and never start a request themselves. A guardian holds none of your keys and can never create a transaction or move funds. Choose guardians you trust, since the required number of them can together approve a recovery to a new device.
What if my phone is stolen?
While the phone is locked, the keys on it are unreadable. The phone holds one of your account's three keys, so moving funds from it also needs Summo's co-signer, which checks each payment against any spending limit you have set and signs nothing once the account is frozen. On an account with guardians, the recovery phrase stored on the phone cannot be decrypted without their approval; without guardians, access to the unlocked phone approximates access to the account. If your phone is stolen, contact support to freeze the account.
04Money and markets
Which networks does Summo support?
Ethereum, Base, Arbitrum, Polygon, Robinhood Chain, and Solana. One Summo account works across all of them.
Do I need the network's native coin to pay fees?
No. A network fee can be paid in the network native coin, in a supported token instead with no native coin required, or with gas credits. Every option and its cost is shown before you confirm.
Can I pay in stores?
In the countries where Summo QR Pay is available, yes. You scan the merchant QR code, and the payment settles from your balance and reaches the merchant in local currency, often through a local payment network people already use, with no card required. QR Pay is live in specific geographies today, not everywhere, and it requires a one-time identity verification in the app.
Which countries is QR Pay available in?
QR Pay is available today across parts of Latin America, Africa, and Southeast Asia, and coverage expands over time, with more countries listed as coming soon. Availability can vary by account as well as by country, to comply with applicable laws and regulations. The current list is on the Payments page.
What can I trade?
Swaps between assets, routed for the best available price across supported networks; perpetual futures on a partner derivatives exchange; and prediction markets sourced from Polymarket. Availability varies by country, to comply with applicable laws and regulations. The fees and risks for each are shown before you confirm.
How do prediction markets work on Summo?
Prediction markets on Summo are sourced from Polymarket and resolve there under its rules. You buy a share in an outcome, Yes or No, at a price between $0 and $1; a winning share redeems for $1 and a losing share for nothing, so the price paid is the most a position can lose. A position is funded from your own wallet and signed on your device, positions and payouts are on-chain tokens held in your wallet, and Summo never holds the funds. A Summo service fee is itemized before you confirm. Prediction markets are not available in many countries, and are for users aged 18 or over. Summo is a verified Polymarket builder.
How does Earn work, and is the yield guaranteed?
Earn puts idle assets into a curated set of third-party vaults, either lending vaults or market-making vaults. Rates are variable and not guaranteed, and each rate is shown before you deposit. Summo takes a performance fee on the yield generated only, never on your principal.
05AI agents
Can I connect an AI assistant like Claude or ChatGPT to Summo?
Yes. Claude, Claude Code, ChatGPT, Codex and other AI apps that support MCP sign-in connect by signing in with a code you enter in the app. Agents that cannot sign in, such as OpenClaw or Hermes Agent, connect with an access code from the app. A connected agent can read your balances, positions and activity, and request actions such as a swap, a perpetual futures order, a send or a payment on Pix or M-Pesa, for you to approve yourself or have approved automatically.
Can an AI agent move my money?
Only with your approval. An agent holds no key and signs nothing; it can only file requests. You approve each request yourself with Face ID, or turn on automatic approval for an agent, and your phone then approves that agent's requests for you, with a receipt for each. Either way, every action an agent requests is signed on your own phone. A request waits up to 12 hours for you, and you can pause or disconnect an agent at any time. An agent cannot change your guardians, spending limits, recovery or settings.
