MAILGENT

Wallet

A smart walletwithout the friction.

Every Mailgent account is backed by a non-custodial smart wallet on Base. Top up with USDC, spend at any Mailgent-enabled merchant, withdraw to any address you control. No seed phrase, no browser extension, no chain to learn.

Most consumer crypto wallets ask the user to memorize a 12-word seed and install a browser extension before they can spend a dollar. That works for the 1% of users who already know what a wallet is. Mailgent Wallet is for everyone else. Sign in with email + password (or any OAuth provider), and a smart contract wallet is provisioned for you on Base. Mailgent acts as the relayer; the user owns the account through the on-chain account abstraction primitive. Funds in, funds out, no glossary required.

How it works

Four steps. Most fire in under a second.

01

Sign up; wallet auto-provisions

Email + password (or OAuth) creates a Mailgent account. A smart contract wallet on Base is provisioned in the background. The user never sees a seed phrase or a chain RPC.

02

Top up with USDC

Three paths: send to the wallet's deposit address from any Base wallet, use the in-console on-ramp (cards, ACH, SEPA), or receive a transfer from another Mailgent user.

03

Spend at any Mailgent-enabled checkout

When a customer hits a Mailgent checkout, the wallet signs the spending intent in a single tap. Mailgent submits the on-chain transaction; the merchant receives funds in about two seconds.

04

Withdraw any time

Send USDC to any Base address through one API call or the console. No payout cycles, no minimums, no holds. Gas is sponsored by Mailgent for typical user spends.

What you get

Built for developers who already shipped.

Non-custodial by design

Mailgent is a relayer, not a custodian. Your keys are encrypted with VAULT_MASTER_KEY, scoped to your account, and revocable. You can always rotate signers or exit to a self-custodial wallet.

USDC on Base, today

Top up by direct deposit, by on-ramp (Coinbase, Moonpay), or by receiving from another Mailgent user. Spend in milliseconds. Withdraw in seconds. Multi-chain is on the roadmap; single-chain UX wins for now.

Spend limits + 2FA

Daily caps, per-merchant limits, and a 2FA prompt on withdrawals over a configurable threshold. Set it once in the console; the wallet enforces it without code on the merchant side.

Refund + dispute primitives

Issue a signed refund through one API call; the wallet sends USDC back to the buyer and logs the reversal. There are no chargebacks because settlement is on-chain and final — disputes go through your support flow with the activity timeline as evidence.

Activity log for every move

Every deposit, payment, refund, and withdrawal writes an entry with timestamp, counterparty, route, and a chain link. Filter by amount, by merchant, by time. Export for accounting.

Passkey + biometric sign-in

Skip the password. The wallet pairs with WebAuthn / passkeys on iOS, Android, and desktop. Biometric on the device unlocks signing without exposing a private key to the browser.

What people build

Real-world wallet flows shipping today.

1-tap

Shopify checkout

Customer clicks 'pay with Mailgent', taps to confirm, returns to the order confirmation page in under three seconds. No redirect to a wallet app, no transaction popup.

Per-call

Agent paying APIs

An AI agent holds a Mailgent wallet bound by a mandate (per-tx cap, per-day cap, expiry). The wallet pays paid APIs and MCP servers within those bounds, with every call recorded.

Auto-payout

Merchant treasury

A merchant accepts USDC into the wallet all day. A scheduled payout sweeps funds to a treasury address every night. Daily reconciliation is one CSV export.

Free

P2P transfers

Send USDC to another Mailgent user by email address. Instant settlement. Useful for refunds, partner payouts, and inside-the-org transfers.

FAQ

Things builders ask.

Is the wallet custodial?
No. Mailgent acts as a relayer; the wallet is a smart contract on Base that the user controls through account abstraction. Mailgent can be replaced as the signer at any time. You always have an exit path to a self-custodial wallet like Coinbase Wallet or Rainbow.
What happens if I lose my password?
Account recovery uses your verified email + a recovery passkey (set up at signup). Mailgent cannot recover the wallet without those — by design, since the alternative would mean Mailgent could move user funds. If both are lost, the wallet's funds are unrecoverable; this is the same posture as any non-custodial wallet.
What chains do you support?
Base mainnet only today. Multi-chain is on the roadmap; we picked Base for low fees, fast settlement, and broad wallet support. If you need a specific chain, let us know what the customer demand looks like.
Who pays gas?
Mailgent sponsors gas for typical user spends — checkout, refunds, P2P. Heavy actions (large withdrawals, on-chain contract interactions outside Mailgent) cost gas to the wallet's USDC balance, converted at the live rate.
Can I bring my own wallet?
Yes. Connect an external wallet (MetaMask, Coinbase Wallet, Rainbow, any WalletConnect-compatible) to your Mailgent account. Mailgent Checkout and Mailgent Pay accept payments from external wallets without provisioning a Mailgent-managed one.
What are the spend limits?
Configurable per project. Defaults are $500 daily and a 2FA prompt on any single transaction over $200. Limits can be tightened or relaxed; agent-bound wallets can be capped much lower per mandate.
Does the wallet work with AI agents?
Yes — this is a first-class use case. An agent's Mailgent Identity can hold its own wallet, bound by a signed mandate that restricts per-transaction amount, per-day total, and counterparty allowlists. The wallet enforces these on-chain via Kernel session keys.
