Cold vs.​ Hot Wallets and How to Use Ledger with Zerion

Dune is discontinuing its SIM product to concentrate resources on its core data platform. Users will need to migrate their services to alternative solutions. **Migration Path Available** Zerion has published a [migration guide](https://zerion.io/blog/migrating-from-dune-sim-to-zerion-api/) to help developers transition from Dune SIM to Zerion API. The guide covers: - Wallet balances - Transaction activity - DeFi positions This follows a similar transition from OneBalance to Zerion API earlier this month.

**Zerion is incentivizing developers** to contribute to their open-source CLI toolkit by offering free API Builder Plans. **Key Details:** - Free Zerion API Builder Plans available for CLI contributors - Application process: [zerion.io/agents](https://zerion.io/agents) - Part of Zerion's broader push into AI agent infrastructure **Recent Context:** Zerion CLI launched as an open-source financial layer for autonomous agents, enabling: - Portfolio management across 40+ EVM chains + Solana - Token swaps and bridges - DeFi position tracking across 8,000+ protocols - Local transaction signing with OpenWallet security The initiative follows Zerion's pattern of supporting developer communities with free API access, similar to their previous hackathon sponsorships.

**Zerion attended Solana Breakpoint conference** in the United Arab Emirates, marking another major crypto event presence for the multi-chain wallet platform. The brief announcement follows Zerion's active conference circuit, including their recent participation at Token2049 in Dubai where they: - Hosted curated dinners with partners - Conducted live "hot ones" challenge with founders - Participated in multichain and Web3 UX panels - Engaged directly with community members Zerion continues building relationships across the crypto ecosystem through strategic event participation and community engagement initiatives.

**Zerion has integrated Tempos testnet** from its launch day, offering comprehensive support for the new blockchain network. The integration includes: - **Consumer wallet interface** for end users - **Data infrastructure** for developers building on Tempos This early support positions Zerion users to **access Tempos functionality immediately** as the testnet goes live, providing both retail and developer-focused tools for the emerging network.

**Zerion now supports Solana liquidity provision** directly within its wallet interface. Users can now: - Add liquidity to Solana tokens - Monitor LP position performance - Manage positions without switching platforms The integration streamlines DeFi operations by consolidating portfolio tracking and liquidity management in one interface. This builds on Zerion's existing Solana portfolio tracking capabilities. **Key benefits:** - Direct LP management from wallet - Real-time position monitoring - Simplified DeFi workflow The feature targets users seeking efficient liquidity provision tools within their existing wallet setup.
