Aug 1, 2025

In Aug 2025, axelarjs delivered two core outcomes: 1) Token Details Page Authentication and UI Guard bug fix to handle wallet-absent scenarios, with guards for recovering deployment message IDs, updating remote token addresses on Sui and Stellar, and conditional rendering of the 'Add Token to Wallet' button. Implemented as part of commit ebab5b17143be7c6a7c9bf37bc4067a4430fb8b7 (fixes for wallet non-existence, #660). 2) Hyperliquid Chain Support: added devnet and mainnet support with new chain configurations, updated RPC URLs, and integration with existing chain definitions to enable recognition and interaction with Hyperliquid. Implemented as part of commit ebe73cd0f9069fc91d1d15e435be3bd5e9430fe2 (Hyperliquid support #661).
