August 2026 expanded transaction tracking across WDK wallets and introduced cloud backup storage, new routing capabilities, and more explicit application controls.

Transaction tracking. Wallet releases add getTransaction() and waitForTransaction() with chain-specific confirmation and finality rules. UserOperation, relay, and Spark identifiers are resolved through their respective providers; a returned hash alone does not establish successful settlement.

Cloud backup. The first backup-cloud beta stores an already-encrypted wallet master key in Google Drive appDataFolder or a CloudKit private database. Applications still own encryption, authentication, and recovery validation.

Swidge providers. The community-maintained 0x module adds same-chain EVM swaps. MoonPay Trade 0.2.0 changes deposit execution and minimum-output checks, while Symbiosis 1.3.0 adds source execution on supported TON, TRON, and Solana accounts. Wallet and provider capabilities must be checked together.

Safer transaction handling. Releases strengthen paymaster and signed-payload validation, add structured WDK errors, and improve fee-cap handling. TRON adds allowance and approval methods, Solana accepts serialized wire transactions, and TON supports raw bag-of-cells message bodies.

CLI and mobile tooling. CLI beta.3 adds declared module-method calls and custom-module management; beta.4 hardens configuration overrides. Worklet tooling adds opt-in method allowlists. React Native beta.17 makes wallet identity and lock/unlock lifecycle caller-owned, and beta.18 requires a compatible expo-crypto peer.

Migration notes. Core policy conditions now read positional args instead of params. Multisig interfaces and result types also changed during August. Review exact version notes before upgrading.
