UI alternatives

EVM Networks

• GitHub: https://github.com/eternalsafe/wallet
• Hosted (IPFS): https://eternalsafe.eth.limo (requires bring your own RPC)
• Local: Can be downloaded and run locally

Solana

• GitHub: https://github.com/Squads-Protocol/public-v4-client
• Features: Verifiable build, self-hostable with Docker, IPFS distribution
• Local: Can be built and run locally

RPC backup options

Basic guidance:

• Multiple providers: Set up accounts with 2-3 different RPC services
  • Ex. Alchemy, Infura, Chainstack, Quicknode, Tenderly
• Avoid correlation: Choose providers that don't share infrastructure, if that information is available
• Private RPCs preferred: Public RPC URLs are typically not sufficient for reliable operation

Administrator responsibilities

Ensure signer preparedness:

• Provide access to offline UI tools listed above
• Verify signers have practiced using backup interfaces
• Test backup RPCs during non-emergency periods
• Document procedures for switching to backup infrastructure

Reference: Detailed usage instructions for signers are provided in Section 4.6 (Signing When UI is Down).

Block Explorer backup options

EVM Networks

Etherscan provides the default block explorer for nearly all EVM chains. In the event that Etherscan is compromised or goes down, it is important to have backup options that can be used for monitoring and investigating transactions.

• https://www.blockscout.com/
• Available for all EVM networks
• Can also be self-hosted, although it requires significant time to run full node and index

Solana Networks

Both explorer.solana.com and Solscan are reliable options for Solana transaction exploration and decoding.

explorer.solana.com - https://explorer.solana.com/

• Can be self-hosted using open source code

Solscan - https://solscan.io/
