Swig: Smart Wallet Tooling for Solana

Swig is a powerful account abstraction toolkit that enables developers to create advanced, programmable Solana smart wallets with features like delegated access controls, fine-grained permissions, social recovery, and cross-chain compatibility.

What is Swig?

Swig is an account abstraction toolkit that empowers developers to create sophisticated, programmable smart wallets on Solana. It’s powerful, open-sourced, and fast to build on - most use cases can be built on Swig in <30 minutes.

Smart wallet functionality has been popular on EVM chains, but less developed on Solana. Swig changes that. Developers can now build smarter on Solana with Swig. See how below.

Current Market Problems

Developments in Web3 have brought many benefits, but simultaneously some table stakes Web2 functions have been lost along the way. Traditional crypto wallets are part of this problem:

• Poor UX: Traditional wallets force users to either give up full control or do everything manually themselves. You could be the best dev, but your app’s experience would inherently be downgraded as a result.
• Payments: While crypto solves many payments challenges, the automated and configurable transaction tooling critical for most payments use cases is still limited.
• General Abstraction: Developers need to rely on users who are blockchain experts to gain traction on their apps due to limited abstraction tooling in the market.
• Onboarding: Seed phrases, onramps, and gas all make onboarding to a new app complicated. Devs are losing the battle before it even starts.

Smart wallets solve these problems, but while smart wallets have seen widespread adoption on Ethereum, Solana has remained underserved - until now.

How Swig Solves These Problems

A Swig wallet is an on-chain account built inside a Solana program that can perform all standard wallet functions while adding powerful programmable features:

Swig Features	Pre-Swig Paradigm	Post-Swig Paradigm
🗝️ Non-Custodial Smart Wallets Devs can create Web2 UX without sacrificing on Web3 self-custody standards	Custody vs. UX Tradeoff ❌ Devs choose between: Self-custody, but complex UX Or ❌ Custodial services, but security risks	Web2 UX + Web3 Self-Custody Control ✅ Create embedded wallets with no intermediaries ✅ Apps can request permissions without managing keys
⏳ Session-Based Authorization Enable temporary, permissioned app access without constant manual approvals	Manual Approval Friction ❌ Users manually approve every transaction ❌ Apps lose traction due to “approve fatigue”	Seamless Session Mgmt ✅ Users approve once per session period ✅ Configurable time limited permissions
🔓 Granular Permissions Delegate specific transaction permissions rather than full wallet control	All-or-Nothing Access ❌ Wallets require full signing authority	Fine-Grained Controls ✅ Role-based permissions ✅ Transaction-type permissions
🔄 Automated Transactions Power subscription payments, payment streaming, and conditional transactions	Manual Payments ❌ Payments are not programmable ❌ Advanced payment logic done off-chain	Programmable Payments ✅ Subscription billing ✅ Payment streaming ✅ Automated rebalancing ✅ Dollar-cost averaging
🌐 Social Recovery & Authentication Manage wallets using social accounts like Google, X, or Facebook through ZK proofs	Seed Phrase Vulnerability & Onboarding Frictions ❌ Complicated user onboarding ❌ No key recovery options	Familiar Recovery & Onboarding Methods ✅ Seamless Web2 user onboarding ✅ Multi-guardian recovery with trusted contacts
⛓️ Chain Abstraction Operate seamlessly across multiple chains	Single Chain Limitations ❌ Separate wallets needed for different chains	Unified Multi-Chain Experience ✅ 1 wallet operates across all SVM chains ✅ Sign SVM transactions with EVM Keys
⛽ Paymaster Integration Cover gas fees for users through a central account	Gas Fee Barriers ❌ Users must hold native SOL tokens for every trx ❌ High-friction onboarding ❌ App experiences can’t be “free”	No Gas, No Problem ✅ Apps cover gas for users ✅ Users can pay gas with other tokens ✅ “Freemium” app experiences possible

Why Swig Makes Solana More Powerful

Solana combined with Swig is a game changer for developers.

	Solana	Solana + Swig
Payments Infrastructure	Solana is emerging as a leader in payments due in large part to its fast transaction settlement speed	Swig expands on this by allowing developers to abstract complexity and create powerful non-custodial payments solutions for consumers and businesses
Consumer Adoption	Solana is the hub for consumer apps	Swig dramatically improves UX for Solana app developers by enhancing key management systems to enable simple and secure product flows
Performance at Scale	Solana’s fast transaction speeds and low fees make it particularly attractive for high-velocity trading and payment use cases But, legacy wallet experiences limit this performance advantage with constant manual approvals and limited transaction programmability	Swig’s optimized design maintains Solana’s high speed and low fees, even with advanced wallet features

How Swig Works

The Swig protocol operates through a role-based system that enables seamless interaction with various services and platforms on Solana. Each role has:

• An authority mechanism that can include social logins, blockchain keypairs, and other authentication methods
• A set of configurable permissions that control what actions can be taken
• Optional session-based authentication for enhanced security

This flexible architecture allows developers to create custom wallet solutions while maintaining security and user control. Whether you’re building DeFi apps, payment solutions, or next-generation consumer wallets, Swig provides the infrastructure needed to create powerful, user-friendly experiences.
