Altude is wallet infrastructure that makes self-custody simple enough for mainstream consumers.
Under the hood: an embedded wallet SDK and gasless transaction relay on Solana.
Fee abstraction, transaction relaying, and stablecoin payments flow without custody risk or transaction gatekeeping.
Apps can integrate like they would with any other wallet infrastructure provider; Altude never touches user keys or key shards.
Give your users a wallet inside your app in minutes. Altude works like other embedded wallets from an integration standpoint but never touches keys or key shards, so you get mainstream-simple onboarding without inheriting custody liability or regulatory exposure.
Let users transact without need to hold SOL for fees. Altude's relay abstracts gas away entirely - and unlike a simple onchain paymaster, the relay layer handles fee logic off the critical path so first-time users can transact the moment they onboard. Businesses pay at the end of the month rather than topping up an onchain paymaster.
Build payment experiences where first-time payments don't create extra cost or friction. Altude handles the fee abstraction and transaction relaying so sending stablecoins feels just like sending a cash-app payment.
Teams building for users outside traditional banking can't ask them to pre-fund gas or navigate seed phrases. Altude removes both barriers while keeping users in full control of their funds - no intermediary custody, no transaction gatekeeping.
Kill the cold start problem. New users can receive and send value in their first session - no gas token purchase, no exchange account, no custody handoff required. Altude relays the transaction; the user keeps the keys.
