Sequence Unveils the Next Era of Web3: Unlocking Developer Scale, Blockchain Utility and Seamless Interoperability

Sequence, the leading web3 developer platform, today announced a major expansion of its vision and product suite, redefining how developers build, scale, and monetize blockchain-powered applications. With a focus on eliminating developer friction and solving ecosystem fragmentation, Sequence is launching new tools that make blockchain development as seamless as web2.

For years, web3’s progress has been hindered by fragmented solutions, slow adoption, and a lack of scalable infrastructure for developers. While blockchains have evolved, the full-stack application layer has remained a challenge—forcing developers to piece together wallets, authentication, indexers, gasless transactions, and marketplaces from multiple providers. Sequence solves this problem by delivering an integrated, full-stack developer platform that unifies the fragmented blockchain landscape.

“The next major challenge isn’t making blockchains faster, it’s about driving utility.”

“Web3 has promised a revolution in digital ownership and economies, but adoption has been bottlenecked by complexity and fragmentation,” said Peter Kieltyka, Co-founder & CEO at Sequence. “The focus has been on scaling raw blockspace, but without seamless developer infrastructure, faster blockchains alone won’t drive adoption. Sequence delivers the missing application layer by giving chains and developers everything they need to build web3 apps at scale."

Instead of treating blockchains as separate networks, Sequence enables a unified, cross-chain experience where developers can build without barriers and users can move frictionlessly across ecosystems.

New product releases: Unlocking developer scale

As part of this expanded vision, Sequence unveils six major products, available either now or in the coming months, that empower developers, chains, and ecosystems to create more scalable, interoperable, and user-friendly web3 experiences.

1. Ecosystem Wallets: A federated wallet experience for your entire ecosystem

A next-generation wallet solution that combines the power of Universal and Embedded Wallets, eliminating the need for users to create new wallets for every app.

• Seamless onboarding – Sign-in with email, social accounts or even bring your own web3 wallet
• Universal accounts – Connect to all chains and apps instantly with a single global wallet account
• Cross-app spending – Bring your items, inventory, history and buying power with you across every app
• Smart sessions – Onchain smart wallet policies enable pre-approved microtransactions and secure high-value transactions
• Your brand – It’s your ecosystem, your brand, and your users. Whitelabel, customize and extend the user experience.

Ecosystem Wallets are a paradigm shift in network effects and interoperability between chains, users and apps that are unique to web3 but previously fragmented due to limited wallet solutions. Sequence Ecosystem Wallets offer a federated single sign-on across a chain’s entire ecosystem of apps and users that drives digital economies and commerce.

2. Ecosystem Manager: full visibility for chains and developers

A new admin portal that gives web3 chains and developers complete insight into their web3 infrastructure.

• User growth and retention tracking – Monitor wallet activity and engagement across applications.
• Transaction analytics – Track spending behavior and marketplace monetization trends.
• Chain-wide developer and app insights – Understand ecosystem growth and liquidity flows.

Ecosystem Manager provides real-time intelligence to help projects optimize user acquisition, retention, and monetization.

3. Chain Abstraction: Onchain payments with any chain, any token, and any wallet with just one-click

A breakthrough in cross-chain payments and interoperability, solving the liquidity fragmentation problem in web3. Sequence’s chain abstraction solution unifies liquidity and seamless transactions across EVMs.

• Universal buying power – Users can buy assets on any chain, with any currency, with any wallet, with just one-click.
• All wallets – Compatible with all wallets including Metamask, Wallet Connect, EOAs and smart contract wallets.
• Seamless cross-chain transactions – Users pay with assets from any wallet, and from any chain.
• Embedded cross-chain SDK – Developers integrate frictionless multi-chain transactions into existing wallet solutions.
• Intelligent liquidity routing – Optimizes for best transaction paths across chains.

Sequence’s chain abstraction technology makes all EVM chains feel like one, unlocking true composability across web3.

4. Sequence Marketplaces: Instantly launch custom marketplaces

A powerful marketplace solution that enables developers to launch fully integrated, high-liquidity marketplaces with a single click.

• One-click aggregated marketplace – Instantly connect to OpenSea, Magic Eden, Rarible, OKX, and more.
• Seamless asset discovery and trading – Enable instant buying, selling, and browsing of digital assets.
• Auction and secondary market support – Real-time bidding and dynamic resale mechanics.
• Embeddable SDK for Unity, Unreal, and web – Marketplace functionality built directly into games and applications.

This update makes web3 marketplaces as intuitive and powerful as Web2 e-commerce while preserving the benefits of true digital ownership.

5. Sequence Indexer: The best alternative to SimpleHash

A high-performance, multi-chain blockchain indexer delivering real-time, reliable, and future-proof access to on-chain data.

• One API for all chains – Query wallet balances, transactions, NFTs, and smart contract events across 46+ blockchains with a single request.
• 3X faster response times – Optimized infrastructure ensures lightning-fast data retrieval.
• Real-time webhooks and event logs – Instantly track transactions, token transfers, and smart contract interactions.
• Spam filtering and automatic contract detection – Clean data without noise.
• Open-source and self-hosted options – Ensures long-term reliability and transparency.

With SimpleHash shutting down, Sequence provides the fastest, most scalable indexing solution for wallets, games, and DeFi apps.

6. Sidekick: One-click web3 backend infrastructure

A serverless, containerized web3 backend that lets developers automate, query, and interact with blockchain data effortlessly, without the hassle of managing infrastructure.

• Automated on-chain actions – Define scripts to execute transactions, send assets, and update smart contracts dynamically.
• Real-time webhooks and event listeners – Set up custom triggers for onchain activity.
• Programmatic querying – Automate access to balances, transaction history, NFT metadata, and smart contract events.
• Multi-chain compatibility – Interact with all supported EVM chains in a single request.

Sidekick eliminates backend complexity so developers can focus on building great applications without managing servers, scaling APIs, or handling infrastructure headaches.
