Solana-Native

Modular. Compat. Mobile-first. No paid assumptions.

Unified SDK for the fragmented Solana mobile client layer: solana-kmp, Sol4k, mobile-wallet-adapter-clientlib-ktx, seedvault-wallet-sdk, and Metaplex KMM. MWA and Seed Vault remain the underlying Solana Mobile primitives.

SolanaBuilt on Solana

Unified. Modern. Coroutine-first.

One SDK for the fragmented Kotlin/Android Solana client layer. Source-compatible migration modules preserve existing imports, plus a first-class Artemis-native surface for new code.

Unified Kotlin SDK

Consolidates solana-kmp, Sol4k, mobile-wallet-adapter-clientlib-ktx, seedvault-wallet-sdk, and Metaplex KMM client code into one modern SDK. Source-compatible shims keep existing imports working.

MWA 2.0 & Seed Vault

Android Mobile Wallet Adapter 2.0 dApp client with P-256 association, AES-128-GCM session cipher, HKDF-SHA256, and Sign-In With Solana. Seed Vault stays the device custody boundary; Artemis provides the client integration.

Token-2022 & cNFTs

Token-2022 tooling with TLV decoding for supported extensions, plus Bubblegum compressed-NFT transfers, marketplace preflight, and failover DAS routing (Helius primary, RPC fallback).

Versioned Transactions

v0 versioned transaction support with Address Lookup Tables, priority fees, durable nonce, dynamic compute-budget planning, and a TxEngine pipeline with blockhash cache and retries.

React Native Bridge

React Native bindings expose the shared TypeScript surface while keeping Solana Mobile primitives Android-only: MWA and Seed Vault run on Android, with iOS routed through explicit fallback hooks.

Reliability layer

WS auto-reconnect with deterministic resubscribe, circuit-breaker RPC endpoint pool, per-transaction batch results, priority-fee oracle, and a framework event bus.

Migrating Solana Mobile client code?

Keep MWA and Seed Vault as the underlying primitives. Swap Maven coordinates to the Artemis compat artifacts underinterop/artemis-*-compatand keep your existing imports. See the migration guide.

FOR SOLANA MOBILE DEVELOPERS

Unified client layer for Solana Mobile apps

Artemis consolidates fragmented client SDK code while staying compatible with MWA and Seed Vault. It keeps upstream Java/Kotlin import names working through dedicatedinterop/artemis-*-compatmodules while exposing a first-class native surface for new code. Fewer dependencies, per-transaction batch results, real reconnect logic, and CI-enforced coverage.
