Code
Code here means Code Wallet, the Solana payments app from Kik founder Ted Livingston. It has nothing to do with coding tools, discount codes or the card wallet brand of the same name. Code launched on iPhone in July 2023. It let you hand someone money by showing a QR code on your phone, much like passing a banknote. Payments were made in Kin, the token Kik created. Code as a brand is no longer active. The same team now ships a newer app called Flipcash, which runs on a dollar stablecoin called USDF. This page covers what Code was, how it worked, and where it went.
Is the Code wallet app still working?
The Code app looks retired, and the team's work has moved to Flipcash. We found no formal notice that Code had shut down. Here is what we saw when we checked on 13 October 2026.
The old website, getcode.com, no longer shows the app. It returns a security certificate made out to other, unrelated sites. The @getcode account on X had not posted in the past 30 days. The team's code-payments page on GitHub is busy, but its app code now belongs to Flipcash. The project still named code-ios-app is labelled "Flipcash iOS App".
If you held Kin in Code, one point matters most: you held the keys. Your funds sat in your own accounts on Solana. The old Code documentation describes a way to reach them without the company's servers. We could not confirm how well the old app or that route works now.
How Code Wallet payments worked: QR cash and the Code Sequencer
Code made a crypto payment feel like handing over cash. You picked an amount and your phone showed a digital bill with a code on it. The other person scanned it to take the money. CoinDesk's launch report from July 2023 called this scan-to-pay step the core feature, with no fee to send.
Behind the app sat the Code Sequencer, which the team called a layer 2 on Solana. A layer 2 handles payments off the main chain and settles them there later. The sequencer docs list four steps. The sequencer tests the payment. The app signs it. The sequencer queues it for Solana. Then it tells the app the payment is done.
The payment felt instant because the sequencer had already checked it would go through. The docs say the sequencer never holds your funds or your keys. It only queues payments you have already signed. Livingston told CoinDesk the layer also kept payments going when Solana was down, and added privacy.
Code Wallet and Kin: from Kik's token to USDF
Kin was the money inside Code. Kik sold Kin in a 2017 token sale that raised $100 million. The US markets regulator, the SEC, later called Kin a security, and Kik paid a $5 million fine, CoinDesk reported. Kin moved across several blockchains before it landed on Solana.
Kin's price swung a lot, which is awkward for an app meant for daily spending. Livingston put the question to CoinDesk this way: "If we eliminate all other challenges except volatility, could it work?"
Flipcash uses dollars instead. Its Android code names USDF as the app's base currency and does not mention Kin. One USDF is worth one US dollar, and each is backed by USDC. Coinbase cbBTC$81,351.16-0.5% issues USDF through its Custom Stablecoins service. The Block reported on 20 May 2026 that USDF was the first coin to launch on that service.
Flipcash: what the Code team builds now
Flipcash is a self-custodial mobile wallet for iOS and Android, built on what the team now calls the Open Code Protocol. It keeps Code's scan-to-pay cash and adds tipping, chat and community currencies. Flipcash Inc. publishes the app, and its privacy policy describes it as a non-custodial wallet.
The product has shifted toward social features during 2026. The App Store listing describes tips between creators and fans, group chats, and direct messages with end-to-end encryption. A user can set a minimum tip that strangers must send to start a chat. In October 2026 Flipcash announced public group profiles, user profiles and rich media in chats on its X account.
The Currency Creator, announced on 10 December 2025, lets a community launch its own currency inside the app. The Reserve Contract repository sets out the rules. Each currency has a fixed supply of 21 million coins. The first coin sells for $0.01, and the price climbs along a fixed curve as more are bought. Buyers pay in USDF, and the contract buys coins back on demand, minus a sell fee.
We covered the Flipcash launch in our summary of Livingston's June 2025 Lightspeed interview.
Code SDK: 5-cent micropayments for websites
The Code SDK let a website add a payment button that accepted amounts as small as 5 cents. The SDK documentation lists a flat 1-cent fee to cover blockchain costs and says the payer needs no sign-up on the site. It ships packages for JavaScript, TypeScript, Go, Python and PHP.
The documentation is still online and carries no deprecation notice. It describes the original Code app, though, and we could not confirm that the button still works now that the Code app is no longer maintained under that name. Treat it as a reference for how the system was designed. Do not build a new integration on it without testing first. Livingston explained the thinking behind micropayments in a November 2023 Lightspeed episode.
Is Code Wallet safe? Audits, custody and what can go wrong
Code was built so that you hold your own keys, and its two core programs were audited. Some things we could not check, and the newer features carry their own risks.
The Code program library lists audits by the security firm OtterSec for two programs, Timelock and Splitter, at version 0.1.0. A third program in the same library, swap-validator, has no audit listed. The newer Code VM, which cuts fees and rent costs for Flipcash, also lists an OtterSec audit. The Flipcash Reserve Contract lists one from Sec3. All of this code is open source.
The Timelock program is what keeps the money yours. Your account needs two parties to sign before money moves: you and the sequencer. The sequencer cannot move funds alone. If it goes away, the docs say you can start an unlock and take your money out after a 21-day wait. That keeps your money safe, but three weeks is a long time to be locked out.
Three limits are worth knowing:
- The team's code pages do not say who can upgrade the programs on Solana. We could not read that from a block explorer for this review. On 13 October 2026, the public check run by OtterSec listed the Splitter program as not verified against its source code.
- Instant payments rely on a sequencer run by one company. Your funds stay yours if it stops, but the app does not work.
- Community coins on Flipcash are priced by a curve. A coin's price falls as holders sell, and each sale pays a fee. A dollar balance in USDF and a balance in a community coin are very different things.
USDF itself relies on Coinbase to issue it and hold its reserves, and on USDC as backing.
Who Code and Flipcash suit
Code was built for people who had never used crypto. There were no addresses to copy and no network fees to think about. That audience now belongs to Flipcash, which suits small in-person payments, tipping creators, and paid-entry group chats.
It is a poor fit if you want a general Solana wallet. Neither Code nor Flipcash is designed for trading tokens across the wider network, using DeFi apps or staking SOL. The iOS app also requires iOS 18 or later.
Developers who want web micropayments should read the Code SDK as a design reference only, for the reasons above.
Who built Code: Ted Livingston, Kik and the $6.5 million seed round
Ted Livingston started Code after running Kik, the chat app behind Kin. Code is based in Kitchener-Waterloo, Canada. An early version came out of a not-for-profit paid for by the sale of Kik, BetaKit reported. The team made its code public in November 2023.
In February 2024 Code closed a $6.5 million seed round led by M13 and Union Square Ventures. BetaKit names five angel backers, two of them Solana's co-founders, Anatoly Yakovenko and Raj Gokal.
The company behind the current app is Flipcash Inc., and Livingston still leads it in public. In October 2026 he wrote on X that the team had spent ten years on a global payment system. He said it was now time to join that with global chat.
