Nothing moves without a tap of your card.

Chimp is an iOS wallet for Stellar where the card is the wallet. The app shows balances and prepares operations. Only the card can sign them.

01 · What it is

A Stellar wallet that lives on a card.

Chimp is a non-custodial Stellar wallet. Its private key lives inside the card's chip and never leaves it. The phone never holds the key, and neither does ChimpDAO.

The iOS app reads balances and prepares each operation. To move anything, you hold the card to the phone, and enter its PIN on cards that have one.

02 · How it works

Three steps, one card.

  1. Live on testnet

    Activate the card

    Hold the card to the phone. The app reads the chip's public key, your Main account is created, and the card signs to link itself to it.

  2. Live on testnet

    Fund it

    Send testnet XLM or USDC to the card's C… address from a Stellar wallet that supports contract addresses.

  3. Tap + PIN each time

    Tap to pay, swap, save

    Every movement of funds asks for a tap of the card, and its PIN if it has one.

Looking is free. Moving money takes a tap.

03 · Security model

Three checks, all on the card.

Security & known limitations →
CHECK 1KEY

The key stays in the chip

The private key is held in the card's secure chip and cannot be exported. The phone sends data to sign and gets back a signature.

CHECK 2PIN

The PIN is checked by the card

On cards with a PIN, the card verifies its own PIN: without the right PIN the chip refuses to sign, whatever phone it is held against. Some cards have no PIN.

CHECK 3INTENT

Every action signs an intent

The card signs an intent bound to the amount, the recipient and the contract. Change any of them and the signature no longer matches.

05 · For partners

Cards in your project's colors.

A Stellar project can issue Chimp cards with its own artwork. The contracts and the security model stay the same; only the card face changes.
