Crypto Mobile Wallet

Overview

A non-custodial mobile wallet: send, swap and stake across chains, with keys that never leave the device.

The Problem

Self-custody wallets fail their users most often through recovery, not security — a lost phone and an unfindable seed phrase is how the majority of personal crypto losses actually happen, not hacks. The client wanted a wallet ordinary users could trust with their recovery, not just their private keys.

• User research turned up a consistent story: a lost or replaced phone, a seed phrase nobody could find, and a wallet balance gone for good.
• Existing recovery options assumed technical confidence — running your own node, understanding multisig — that most target users didn't have.
• Gas estimation on early builds was wrong often enough that failed transactions were a top support complaint.

How We Solved It

We treated recovery as the primary design problem, not an afterthought to security. Social recovery and encrypted cloud backup exist alongside the standard seed phrase, so losing a phone doesn't mean losing the wallet. Every outbound transaction is biometric-gated, and multi-chain send, receive and swap ship with gas estimation that doesn't guess wrong.

• Multi-chain send, receive and swap, with reliable gas estimation.
• In-app staking for supported chains, no separate validator setup.
• Social recovery as an alternative to a single point-of-failure seed phrase.
• Biometric-gated signing for every outbound transaction.

Key Decisions

• Social recovery as a first-class option, not an advanced setting. Three trusted contacts, not a technical concept most users would never enable.
• Gas estimation with a safety margin and a simulate-before-send step, trading a slightly higher quoted fee for a transaction that doesn't fail.
• Keys generated and stored in the device's secure enclave, never touching application memory in plaintext.

The Result

Users have a real recovery path that doesn't depend on a piece of paper surviving a house move, without weakening the non-custodial guarantee that keys never leave the device.

Failed-transaction support tickets dropped by more than half after the gas estimation rework, and social recovery has been the primary recovery path used in every real recovery case since launch.
