IV. Why should SubWallet be supported?

The wallet plays a crucial role in a blockchain ecosystem
A blockchain wallet serves as a cornerstone for any thriving ecosystem, comparable to a browser in the realm of the internet. Without a functional blockchain wallet, users have no access to ecosystem features and applications, which hinders the ecosystem's potential for growth. Therefore, the wallet is an important infrastructure for the ecosystem that should receive support for its development.
SubWallet team is committed to efficient treasury spending
We have been highly focused and committed to building products and shipping new features. We consistently prioritize product delivery and gaining traction, ensuring that what we build contributes tangible value to the ecosystem before seeking any funding. In other words, we always apply for retroactive funding. This has set a standard for other teams to follow our approach, and as a result, foster greater efficiency in treasury spending.
SubWallet team makes a comprehensive contribution to Polkadot ecosystem growth
In addition to our proficiency in product development, we possess robust marketing and sales capabilities. We are capable of effectively bringing our products to market and expanding our user base, rather than building a product with very few users. We firmly believe that we have actively contributed to the growth of the ecosystem, making it more vibrant and robust.

V. What problems have SubWallet solved in this proposal?

A. Unified solutions to reduce fragmentation

✅ Unified Address Format

🎉 Managing multiple address formats across the Polkadot ecosystem can be a frustrating and fragmented experience for users. To address this challenge, we’ve partnered with the Polkadot UX Bounty team to introduce the Unified Address Format in our extension version 1.3.22. This update enhances the wallet experience by providing:

🎯 Simplified user experience
🎯 Consistency across ecosystems
🎯 Improved ecosystem usability

Announcement:

B. Enhance real-life usability

✅ Seamless Dynamic Ramp Orchestration with Meld

Say goodbye to the hassle of managing multiple token types when performing On-ramp transactions! SubWallet, in collaboration with the DeFi Bounty program, introduces Dynamic Ramp Orchestration, allowing users to seamlessly access six leading On-ramp solutions—Banxa, Coinbase, Binance, Transak, PayPal, and Unlimit—all from a single, unified interface.

This solution supports 45 countries, 16 fiat currencies, 699 cryptocurrencies, and 15 payment methods, making asset onboarding more efficient and accessible than ever. 🚀

Announcements:

https://x.com/subwalletapp/status/1905622194971144678

✅ Seamless Crypto-to-Fiat Conversion via VISA, MasterCard, SEPA

Beyond just On-ramp services for converting fiat to crypto, Off-ramp capabilities—allowing users to convert crypto back to fiat—are equally essential. Recognizing this need, SubWallet becomes the first wallet in the ecosystem to offer a seamless Crypto-to-Fiat conversion experience for supported tokens.

With just a few clicks, users can cash out 23 tokens, including DOT, ETH, GLMR, and KSM, directly into fiat via VISA, Mastercard, SEPA Bank Transfer, and Faster Payments.

This feature is now available on the SubWallet web dashboard, powered by our integration with Transak. 🚀

Announcement: https://x.com/subwalletapp/status/1861007154989392183

C. UX improvements to reduce complexity

✅ 1-Click Cross-Chain Liquid Staking for DOT on Polkadot with Bifrost

Liquid staking has never been easier! With SubWallet, users can now stake their DOT on Polkadot directly to the Bifrost protocol in just one click, bringing a seamless multichain experience that feels as simple as staking on a single blockchain.

This streamlined process not only helps secure the network but also enables users to earn rewards while receiving vDOT (derivative DOT) at the same time, maximizing their staking potential effortlessly. 🚀

Announcements:

https://x.com/subwalletapp/status/1899863006802305156

✅ Seamless Transactions with Custom Gas Tokens

Custom gas tokens revolutionize the transaction experience by allowing users to pay fees with any supported token, eliminating the need to hold native tokens. This is a major breakthrough in the Polkadot ecosystem, making it easier than ever for users to engage with dApps and services.

At SubWallet, we’ve quickly integrated this feature into transfer and swap functionalities on Polkadot Asset Hub and Hydration, ensuring a frictionless user experience.

From SubWallet Extension v1.3.19, users can cover gas fees on Polkadot Asset Hub with their favorite tokens, including DOT, USDT, USDC, MYTH, PINK, WETH, STINK, PEPE, and more.
From SubWallet Extension v1.3.24, the feature expands to Hydration, allowing users to customize gas payments with over 20 assets, such as DOT, vDOT, vASTR, USDT, USDC, MYTH, PHA, GLMR, UNQ, SUB, KILT, SOL, and more.

This upgrade enhances flexibility, improves accessibility, and eliminates barriers for users transacting within the Polkadot ecosystem. 🚀

Announcements:

✅ Stay Updated with In-App Notifications on SubWallet

Never miss an important update! SubWallet's in-app notification system keeps you informed about transaction statuses, staking updates, governance proposals, and more—all within the wallet interface. Easily manage your notifications, customize preferences, and stay in control of your on-chain activities without leaving SubWallet. 🚀

D. Enhance commercial capabilities, asset conversion and connectivity

✅ One Click, One Transaction – Seamless Cross-Chain Swaps for DOT

Effortlessly swap native DOT cross-chain to USDT, USDC, and ETH on Ethereum, as well as USDC and ETH on Arbitrum—all in just one click.

Interoperability and asset conversion are key to expanding the Polkadot ecosystem and attracting users from Ethereum, the largest blockchain ecosystem today. To bridge this gap, SubWallet has pioneered a seamless one-click swap solution, enabling users to convert assets between Polkadot and other major ecosystems with ease.

With this feature, users can swap ETH or stablecoins for DOT and vice versa, without the need for manual bridging or multiple steps. This streamlined experience eliminates friction, making it easier than ever to onboard new users into the Polkadot ecosystem. SubWallet is leading the way in bringing this next-level convenience to the community. 🚀

Announcement:

✅ One click, one transaction — swap native DOT cross-chain to TAO on Bittensor

Following our Ethereum integration, we’re expanding the ability to connect and convert assets from Polkadot to Bittensor, a leading AI blockchain built on the Polkadot SDK. With this update, users can now enjoy an effortless one-click swap between DOT and TAO, enhancing the overall cross-chain experience with simplicity and speed. 🚀

Announcement:

https://x.com/subwalletapp/status/1871170160251621864

✅ Swap in a snap with 200+ swap pairs on Hydration in SubWallet

Asset conversion is a cornerstone of any blockchain ecosystem, and Hydration serves as the only AMM for all assets within the Polkadot ecosystem, making it the primary liquidity hub for the network. Recognizing the importance of seamless asset swaps, we’ve swiftly integrated over 200 swap pairs into SubWallet, empowering users to easily convert their assets through Hydration. With this feature, users can effortlessly exchange their assets, ensuring a smooth and efficient experience across the ecosystem. 🚀

Announcement:

✅ One Click, One Transaction — Seamless Cross-Chain Swaps Between System Chains and Parachains

SubWallet goes beyond the traditional single-chain swap experience by pioneering a 1-click cross-chain swap for assets within the Polkadot ecosystem. Leveraging Hydration and Polkadot Asset Hub, users can now easily convert assets across system chains and parachains, transforming what used to be a complex multichain process into a seamless, single-chain-like experience.

With this feature, SubWallet offers the most comprehensive asset conversion solution in the Polkadot ecosystem, allowing users to manage and convert assets with incredible flexibility and ease.

Now, users can effortlessly swap assets in just a few simple steps:

Between Polkadot ecosystem chains
Between Polkadot and Ethereum
Between Polkadot and other emerging ecosystems

SubWallet is at the forefront of simplifying asset conversion and enhancing cross-chain interoperability. 🚀
