Wallet & DeFi Integration

Wallet connect, DeFi protocol integrations, and fiat on-ramps, wired into your product so users can hold, move, and use crypto without the integration itself becoming a liability.

Wallet integrations fail quietly until they do not

A wallet connection that works in a demo can break on a wallet update, a chain reorg, or a protocol upgrade nobody noticed. DeFi integrations add another layer: the protocol you integrate with is itself a piece of software that can change or fail. This work is about handling that reality, not just the happy path where everything behaves.

What we build

  • Multi-wallet connect covering MetaMask, WalletConnect, Coinbase Wallet, and similar
  • DeFi protocol integrations for staking, swaps, or lending against an existing protocol
  • Multi-chain or cross-chain support where your users are not all on one network
  • Fiat on-ramp integration so users can buy crypto without leaving your product
  • Gasless transaction support where paying gas is a barrier for your users
  • Monitoring so a broken integration is caught before users report it

How the build runs

  1. 1

    Map the flows

    2-3 days

    We list every wallet action a user needs to take and which chains and protocols each one touches.

  2. 2

    Choose the integrations

    2-3 days

    Specific wallets, protocols, and on-ramp providers are selected based on your users and their reliability track record.

  3. 3

    Build and connect

    1-3 weeks

    Integrations are built with explicit error handling for the failure states wallets and protocols actually produce.

  4. 4

    Test against real conditions

    3-5 days

    Testing covers rejected transactions, network switches, and stale wallet state, not just the successful path.

  5. 5

    Ship with monitoring

    1-2 days

    Alerts are in place for failed transactions or a protocol integration going down.

How we work

How we deliver

  1. 1

    Discovery & Scoping

    1-3 days

    We start by understanding the actual problem and your existing systems, not just the brief.

  2. 2

    Architecture & Plan

    2-4 days

    We map the technical approach and integration points before any code gets written.

  3. 3

    Build

    1-8 weeks, scoped to your project

    AI-augmented development that moves fast without skipping review.

  4. 4

    Test & Launch

    2-3 days

    Real testing against real scenarios before it touches a live user.

  5. 5

    Tune & Support

    Ongoing

    We monitor and refine in the weeks after launch. This isn't a handoff and disappear.

What you get out of it

  • Wallet connections that handle the failure states, not just the demo path
  • DeFi features that work against the actual behaviour of the protocols you integrate
  • Users on different chains and wallets all getting a working experience
  • Visibility when an integration breaks, before your users tell you

Questions we get about this

MetaMask, WalletConnect, and Coinbase Wallet cover most users and are supported by default. Additional wallets are added based on where your actual users are.
