Signoff is a Jupiter-first Solana review layer that simulates swaps, decodes transaction intent, and gives users a clear approval brief before they sign.
Frontier MVP in progress
Current public focus:
- review a Jupiter swap before signing
- simulate expected execution
- decode route and instruction context
- summarize token flows, fees, slippage, and risk
- generate a shareable approval brief for signers and teammates
Solana swaps are fast and composable, but signing is still often based on partial context.
For advanced users, treasury operators, and multisig signers, a single Jupiter swap can hide complexity across routing, slippage, setup instructions, cleanup instructions, unfamiliar tokens, and irreversible execution. Wallet warnings help, but they do not provide a dedicated high-confidence review workflow for Jupiter swaps or signer coordination.
Signoff turns an opaque Jupiter swap into an approval packet.
The MVP will:
- ingest a Jupiter swap request or transaction payload
- simulate the swap path with Solana RPC
- decode route and instruction context
- summarize expected token inputs, outputs, fees, slippage, and route complexity
- flag basic risk conditions
- generate a plain-English review brief before the user signs
Signoff is intentionally:
- non-custodial
- read-first
- human-in-the-loop
- narrow in scope for the first release
Generic transaction safety is not the strongest wedge because wallet previews and security tooling already exist.
The sharper opportunity is workflow:
- treasury and multisig signers who need a clearer pre-sign review step
- Jupiter power users making higher-value or more complex swaps
- teams that currently pass around screenshots, quotes, and wallet prompts in chat
Signoff is not trying to replace wallets. It is trying to improve decision quality right before approval.
