Zelcore 8.27.0 ships a completely rebuilt address derivation system covering 30+ blockchain families and adds full Osmosis blockchain support, making this one of the most infrastructure-heavy releases in recent memory. The changes are largely under the hood, but they directly affect wallet loading speed, long-term maintainability, and the range of chains Zelcore can support going forward.
At a glance
- New Address Generation Engine with unified BIP44 derivation across all supported blockchain families
- Encrypted address caching with automatic cache regeneration on version mismatch
- Osmosis (OSMO) blockchain support with native coin and USDC token
- FluxNodes collateral public key now visible in the node dashboard
- XRP transaction history expanded to include non-payment transaction types
Address Generation Engine
The Address Generation Engine is a complete replacement of Zelcore's address derivation layer, built around unified BIP44 derivation logic with dedicated per-family address generators for every supported chain. Before this release, address generation was handled by scattered, chain-specific code paths. The new engine consolidates that into a single coherent system.
In practice, users will notice the change most on wallet load. The engine introduces encrypted address caching, so addresses derived from your seed do not need to be recomputed from scratch on every session. If the engine detects a version mismatch between the cached data and the current build — which will happen automatically after this update — it regenerates the cache cleanly and stores the new result.
The breadth of coverage is worth spelling out. The engine handles Bitcoin variants across all four address formats: Legacy, SegWit, Native SegWit, and Taproot. Beyond Bitcoin, it covers Ethereum-like chains, Cosmos-based chains, Solana, Cardano, TON, Tron, Substrate/Polkadot, Stellar, XRP, Algorand, Near, Sui, Kadena, Alephium, Ergo, Neo, Ontology, Veriblock, Veil, Kaspa, BNB, Avalanche, EOS, FIO, and more. That list encompasses the full range of chains currently supported in Zelcore.
The strategic value here is durability. A unified derivation layer means adding a new chain family in the future requires plugging in one generator rather than wiring up isolated logic. For users, the immediate payoff is faster wallet loading; for the platform, it is a foundation that scales cleanly as the supported chain list continues to grow. The encrypted cache is also tied to the version of the engine that produced it, so future engine updates will always invalidate stale cached addresses rather than silently serving incorrect data — a meaningful safety property for a self-custodial wallet.
Osmosis (OSMO) Blockchain Support
Osmosis is a Cosmos-based blockchain, and 8.27.0 brings it into Zelcore as a fully integrated chain. Users can now hold, send, and receive the native OSMO coin, and the integration also includes USDC token support on the Osmosis network.
Adding Osmosis was a natural extension of Zelcore's existing Cosmos ecosystem coverage. Because the Address Generation Engine already handles Cosmos-based chains through its unified derivation path, onboarding Osmosis follows the same technical pattern as other Cosmos networks already in the wallet. Users who already hold assets on Cosmos-adjacent chains will find the experience familiar: the same address format conventions and the same send/receive workflow apply.
To access Osmosis, users can search for OSMO in the asset management section and add it to their portfolio. USDC on Osmosis is available as a separate token entry. As with all Zelcore-supported chains, the private key never leaves the device — the self-custodial model applies fully to Osmosis holdings.
Having both the native OSMO coin and USDC available from day one means users can hold the chain's primary assets without waiting for follow-up token additions.
Smaller updates
Several smaller but user-facing improvements shipped alongside the headline features.
FluxNodes collateral public key is now visible directly in the node dashboard and edit dialogs. Node operators who need to reference the collateral public key for external tooling or verification no longer have to derive it separately.
XRP transaction history now includes non-payment transaction types. Previously, the history view was limited to payment transactions; this change surfaces the fuller picture of on-chain activity for XRP wallets.
Application performance received meaningful attention: the build was optimized with improved code splitting across vendor bundles (vendor-vue, vendor-element-plus, vendor-blockchain, and charts), resulting in faster initial load times. The encryption layer was also refactored to use the Web Crypto Subtle API with compression support, improving cryptographic operation performance. CSV export for portfolio data received enhanced data handling, and Veil dependencies were updated with adjusted patches.
How to update
Zelcore updates automatically on desktop when the app is restarted. On mobile, updates roll out through the App Store and Google Play — check for a pending update if you do not see 8.27.0 listed in the app's about screen. To download Zelcore fresh or grab a specific platform build, visit zelcore.io/download. After updating, the Address Generation Engine will regenerate your address cache on first launch — this is expected behavior and completes in the background.
