Down the Memory Lane

Last year, Yoki Origins debuted, blending the thrill of collecting with the magic of Japanese folklore. Yoki Origins invited users to journey out and discover all the hidden Yoki, an adventure that unfolded alongside numerous partners. The project quickly became a hit, driving strong engagement and millions of onchain transactions.

During the weeks of traveling around Yoki world, participants fused Yokis and filled in missing Notebook entries - all culminating in the Blossom event, where many were rewarded with token rewards for their efforts.

This April, Yoki Origins returns — revamped, reimagined, and ready to spark a new wave of excitement on Soneium!

Introduction

Yoki’s Transition to Soneium

This relaunch marks a significant step forward for the Yoki Origins IP, as Yoki Legacy officially joins the Soneium ecosystem. Our goal is to deliver a fresh, dynamic, and highly engaging experience tailored for the Astar & Soneium communities. Here, your Yoki is more than just a character — It is your passport to a new era of collecting!

Yoki Legacy - Simpler, Sharper, More Fun

Yoki Legacy is built on everything that made Yoki Origins a success, but with a sharper focus and cleaner gameplay. Yoki Legacy offers streamlined gameplay, improved mechanics, and a more engaging experience, which is both intuitive and deeply rewarding. The real fun begins on the path to completion!

ASTR Token Integration

With direct ASTR integration, Yoki Legacy unlocks real value for every participant. ASTR isn’t just a token; it’s your adventure's engine, giving you tangible utility and aligning with our vision of establishing ASTR as the native token across the Soneium ecosystem.

What’s New in Yoki Legacy?

Do you know what ‘really’ matters most in the character industry? It’s not the price. It’s not even a rarity. The real selling point? Cuteness. That irresistible urge to collect something just because it’s adorable — that’s what drives true hype. And after that? It’s all about the potential value.

Let me tell you a story. My grandma didn’t leave me a dope old mansion — BUT she left me a 30-year-old NBA player photo ticket. Back then, it was $10. Today, the most expensive NBA card ever sold — a 2009-10 Stephen Curry Rookie Logoman Autograph — went for $5.9 million. That’s the power of collecting.

Anyone who’s ever collected character goods knows: Just owning them is the reward. That’s why, even if people say, “Aren’t you too old for this?”— we keep collecting. Because the joy of cute collections never fades.

For NFT collectors with a passion for completing sets, Yoki Origins was a perfect fit, especially with irresistibly cute characters. The hype only grew stronger.

Here’s the kicker: In Yoki Origins (the previous version of Yoki Legacy), collectors didn’t just get digital bragging rights — they actually scored real incentives for every Yoki they collected and fused. Seriously, that’s the kind of hype and reward we’re talking about.

From Cutesy to Valuable: Your Ultimate Guide

So, how is Yoki Legacy both adorable and rewarding? Like the title says, this is your “All-You-Can-Read” Yoki Legacy buffet. I’m serving up everything you need to start your new adventure.

As you can see in the image above, the core gameplay of Yoki Legacy is just like Yoki Origins. You mint capsules with OMASTR tokens, and when you open a capsule, you get a Basic Yoki inside. Since each capsule gives you one Basic Yoki, you’ll need to collect all 12 different capsules to complete your Notebook collection. If you gather three of the same Basic Yoki, you can fuse them to create an Evolved Yoki — there are 12 Evolved Yokis in total.

Ready to see how it all works, step by step?

Get OMASTR: Your Key to the Yoki World

Start here
Mint OMASTR with ASTR (1 transaction needs 2 ASTR, and you get 4 OMASTR). There is no limit on minting OMASTR, so you can mint as much as you want, whenever you want.
Pro Tip: Fill your bag with OMASTR so you can do everything in one go. No breaks needed!

Mint Capsules from YoPort with OMASTR

YoPort is a Gacha machine where you can mint capsules. If you want more details, check the latest article.
Go on to the [Travel] tab on the left side, and click [Town], [Station], and [Forest] to look out for YoPort.
There are 3 YoPort (one released each week), each with 4 different capsule types.
Mint 1 capsule with 1 OMASTR. There is a 25% chance of getting each capsule from a machine.
Pro Tip 1: Get at least 3 of each capsule. That way, you can fuse them right away for an Evolved Yoki.
Pro Tip 2: Get a fourth capsule so you can fill in the placeholder in the Notebook for that discovered Yoki. Since the fusion burns the Basic Yoki.

Open Capsules to Get Basic Yoki

Click [Fusion Springs]-[Capsules] tab.
Open 1 capsule with 3 OMASTR, and get one basic Yoki inside.

Fuse Basic Yokis for Evolved Yoki

Click [Fusion Springs]-[Fusions] tab.
Fuse 3 identical basic Yoki for 1 evolved Yoki with 4 OMASTR.
Basic Yokis used in fusion get burned, so you must recollect them to complete the Notebook collection.

Track Your Notebook Collection

Click [Notebook]-[Season 2] tab.
24 Yoki total (12 basic + 12 evolved), dropped over 3 weeks.
All your Yokis are collected in your Yokicho Notebook, inspired by Japan’s Goshuincho tradition.

Why Collect? The Real Rewards Behind “Kawaii”

Now that you know how to complete your adorable Yoki collection, let’s talk about what kind of real rewards your collection can bring. Yoki Legacy is a whole new experience compared to Yoki Origins—but one thing remains the same: collecting is all about the rewards!

Here’s what’s waiting for you this season:
