For DeFi protocols
Keep users after the incentives end.
Launch a branded, non-custodial wallet and card for your dex, perps or lending protocol. Users spend what they earn without leaving for an exchange, and you earn interchange on every card payment.
Incentives broughtusers in.
Now you need something that keeps them.
You don’t own the relationship
Users arrive through third-party wallets and frontends, so your brand sits one step removed.
Gains leave through exchanges
To spend what they earn, users off-ramp elsewhere, and many don’t come back.
A card program is a project of its own
It needs a team, partners and compliance work your protocol doesn’t have.
Protocols usually call us when
An incentive or points season ends
TVL or volume falls after incentives
A rival launches a wallet, card or stablecoin
A new funding round frees budget for growth
A wallet and card your users keep comingback to
Launched from a self-serve portal, with your protocol already integrated.
Your protocol, intheir pocket
A branded, non-custodial wallet with your protocol built in, plus a browser for the rest of DeFi. Users keep their keys; you keep the relationship.
