Swig

Swig is an open-source account abstraction toolkit built on Solana that lets developers embed programmable, non-custodial smart wallets into their applications — replacing static keypair wallets with permission-layered accounts that support session keys, social sign-in, gasless transactions, and cross-chain identities.

What Swig Does

A Swig wallet is an on-chain account that lives inside a Solana program. It performs all the functions of a conventional wallet — holding assets, signing transactions, interacting with DeFi protocols — but adds a programmable permission layer on top. Developers can use the Swig SDK to construct wallets that behave according to customizable rules: which addresses can authorize which actions, for how long, and over which assets.

This architecture solves a persistent friction point in Solana application development. Standard Solana wallets are controlled by a single keypair. Swig replaces that single-key model with a composable authority and permission system, allowing applications to grant scoped, revocable access rather than requiring users to sign every transaction manually or expose a master key.

Core Architecture: Authorities, Permissions, and Sessions

Swig's on-chain wallet model is organized around three primitives:

Authorities define who or what can control the wallet. Rather than being limited to a Solana keypair, an authority can be a Google account, an X (Twitter) account, an Ethereum keypair, or a Bitcoin key — verified through zero-knowledge proofs or OAuth-based identity flows. This means users can log into a Swig-powered application with familiar Web2 credentials and receive a fully non-custodial Solana wallet without ever handling a seed phrase.

Permissions define what each authority can do. An application might grant a session authority permission to swap up to $100 of a specific token, or to call a particular DeFi protocol, without that authority touching any other assets in the wallet. Permissions can be scoped by asset type, protocol, transaction type, and spending limit.

Sessions add a time dimension. Session keys give an authority temporary access — enough for an in-app trading bot to execute a strategy over a defined window, or for a subscription service to pull recurring payments, without requiring the user to approve each transaction individually.

Together these primitives enable pull payments, subscription billing, portfolio automation, multi-role collaborative wallets, and gasless onboarding — application patterns that were difficult or impossible to build cleanly on Solana before account abstraction tooling became available.

Developer Integration

Swig is designed for developers building consumer-facing Solana applications. The SDK is available in TypeScript and Rust, with a REST API for backend-to-backend use cases and an IDP (identity provider) SDK that handles OAuth and OTP login flows. Developers can integrate at different levels of abstraction — working directly against the on-chain protocol, using hosted backend services for transaction preparation, or composing both.

An embedded paymaster in the Swig stack handles gas fee sponsorship, allowing applications to cover transaction costs on behalf of users and remove the SOL balance requirement that typically blocks new Solana users from onboarding.

The Swig Developer Portal, launched in January 2026, consolidates SDK documentation, integration guides, and reference implementations. Swig claims developers can add smart wallet functionality to an existing Solana application in under thirty minutes.

The on-chain program is written in Rust using the Agave toolchain (version 2.2.1 or higher). The code is published under the GNU Affero General Public License v3.0 and is available at github.com/anagrambuild/swig-wallet. As of mid-2026 the repository has approximately 472 commits, 47 stars, and 16 forks, indicating active ongoing development.

Token and Assets

Swig has no native token. The protocol is infrastructure for building wallet experiences rather than a standalone DeFi application; it does not issue or require a governance or utility token. Wallets built on Swig can hold any SPL token or SOL.

Security and Audits

Swig has undergone an independent security audit by Accretion, a Solana-specialized security firm that has reviewed more than 60 Solana protocols securing over $2 billion in total value locked. The audit report is available from the Swig team upon request. The team has indicated plans for additional audits as the protocol matures. The AGPL v3.0 license means the on-chain program code is publicly auditable by anyone.

Team and History

Swig was built by Anagram Ltd., a crypto-focused venture and development firm operating under the Anagram Build division. The project was publicly introduced in March 2025 alongside the open-source release of the swig-wallet repository. Anagram's first in-house application of Swig was Glider, a subsidiary product that uses Swig's account abstraction to power automated, gasless multichain portfolio strategies on Solana.

Partnerships and Integrations

Since its announcement, Swig has accumulated several notable integrations:

Para (July 2025): Wallet infrastructure provider Para integrated with Swig to offer Solana developers a combined embedded wallet and smart account stack. The integration enables gasless user onboarding, session-key-based transaction bundling, and role-based permission grants within consumer applications.

Glider (January 2026): Anagram's portfolio automation product Glider used Swig to demonstrate gasless automated rebalancing on Solana, serving as the public reference implementation for how Swig session keys and paymasters can power autonomous trading workflows.

Rhinestone (July 2026): A partnership with Rhinestone added multichain intent routing capabilities to Swig-powered wallets, extending the protocol's reach across multiple SVM-compatible networks.

Anchorage Digital — Porto (August 2026): Anchorage Digital, a federally regulated institutional crypto bank, integrated Swig smart accounts into Porto, its institutional self-custody wallet. The integration enables institutions holding assets in Porto to interact with Solana DeFi protocols — including Jupiter, Orca, and Kamino — through Swig's programmable permission model. This represents the first significant institutional deployment of Swig and validates the protocol for security-sensitive, regulated use cases.

Solana Ecosystem Fit

Swig addresses a gap that has limited Solana's consumer and institutional application layer: the absence of a standard account abstraction primitive. Ethereum developers have had ERC-4337 and related smart account standards since 2023, enabling features like social recovery, session-based access, and fee sponsorship. Solana's high throughput and low fees are well-suited for these patterns, but the ecosystem lacked a well-audited, developer-friendly framework to implement them.

Swig fills that gap as a Solana-native account abstraction layer. Its role-based authority model is designed around Solana's account architecture, avoiding the overhead that would come from porting Ethereum-style approaches. The protocol's open-source release and permissive developer tooling position it as potential shared infrastructure for the next generation of Solana consumer apps, DeFi protocols, and institutional custody products.
