4.8.0

What's Changed

• fix: update key retrieval methods to return nullable types on failure by @sergei-boiko-trustwallet in #4849

Breaking Changes

• TWHDWallet.h API change: TWHDWalletGetMasterKey, TWHDWalletGetKeyForCoin, TWHDWalletGetKeyDerivation, TWHDWalletGetDerivedKey, TWHDWalletGetAddressForCoin, TWHDWalletGetAddressDerivation, and the TWHDWalletGetExtended*Key* family now return nullable values (_Nullable) instead of always-non-null, returning null/nil on derivation failure (e.g. empty mnemonic entropy) rather than an invalid or default value. Callers on Swift/Kotlin/JNI/WASM bindings must handle the null case. See #4849.
