Minitel
Minitel is an external transaction decoding system developed by Kiln that provides enhanced visibility before transaction approval.
minitel.app is the Kiln-hosted version running on Vercel. The source code is open source and can be self-hosted. Kiln is also working with partners to integrate it into their interfaces (e.g., Fireblocks). The audit report can be seen here and on the Quantstamp website here.
The Kiln-hosted version offers dedicated Minitel instances for each blockchain (full list) with easy navigation between these chain-specific instances.
Each chain-specific Minitel parses and decodes serialized transactions, providing clearer visibility by displaying transaction details in a human-readable format. The decoded data includes warnings for actions requiring special attention—such as modifying stake account authority.
In addition to presenting decoded transactions in JSON format, Minitel provides a summary of the transaction's actions. The format varies by blockchain to accommodate each chain's unique characteristics; for SOL, it shows an overview of each instruction.
To help users understand decoded transactions, Minitel offers an interactive decode playbook. The playbook's sample mode displays side-by-side examples of typical flows with clear, step-by-step breakdowns of each instruction—making it easier to verify transactions before signing. For each blockchain, it includes examples of supported operations (e.g., Solana: stake, deactivate, withdraw, merge, split).
