SLV Supports All 4 Major Solana Validator Clients on Testnet

SLV Supports All 4 Major Solana Validator Clients on Testnet

2025.09.27
ELSOUL LABO B.V. (Headquarters: Amsterdam, the Netherlands, CEO: Fumitake Kawasaki) and Validators DAO announce that the open-source validator management platform "SLV" now supports all four major validator clients (Agave, Jito, Firedancer Agave, Firedancer Jito) used in the Solana testnet.

Solana Foundation Delegation Program and Testnet Requirements

Until now, on the Solana testnet, there was no restriction on which validator client could be run. However, as the Solana ecosystem has matured, more detailed testing and verification are required. To participate in the Solana Foundation Delegation Program (SFDP), validators are now expected to run the same type of client on the testnet as they do on the mainnet.
Validators who fail to meet this requirement will be excluded from SFDP, losing access to staking support from the Solana Foundation, and consequently finding it more difficult to attract delegation. For this reason, properly running the major clients on the testnet has become more important than ever for validators.

SLV Now Supports All 4 Validator Clients

With this update, SLV now supports all four major validator clients (Agave, Jito, Firedancer Agave, Firedancer Jito). This enables operators to launch any required testnet client environment with a single command, ensuring immediate readiness for future requirement changes.
There is no longer any need to manually handle complex self-builds or parameter adjustments. Anyone can confidently launch the client they need. This dramatically reduces the operational burden not only for existing operators but also for those who want to join as new validators.

Continuous Improvement and Community Support

SLV has been continuously developed and improved to support validators who are short on time or face complex migrations. The full support for all major clients is part of this ongoing effort, and we will continue to evolve SLV by reflecting feedback from the community. Contributions and improvement proposals are always welcome.

Challenges Solved by ERPC and Validators DAO

  • Transaction failures and latency fluctuations common in typical RPC environments
  • Performance limitations imposed by many infrastructure providers
  • The significant impact of network distance on communication quality
  • The difficulty small projects face in accessing high-quality infrastructure
During the development of the open-source Solana NFT card game project Epics DAO, we faced the challenge of not having easy access to a high-quality, high-performance Solana development environment. In response, we built our own platform, which became the foundation for ERPC and SLV.
Financial applications are especially mission-critical, where delays and errors directly impact the user experience. In Solana development, where decentralized validators and Web3-specific mechanisms overlap, it is often difficult to see the full picture, leaving many projects struggling with delays and instability.
We provide the high-performance infrastructure that is needed, contributing to better development experiences and user experiences across the Solana ecosystem. Both ERPC and SLV are positioned as part of this effort.
