ChainLock Evidence
In Active DevelopmentIf it matters in court, it belongs in the chain.
Not for sale yet
This is an honest preview of a product in development. There is no buy button because there is nothing built to buy. Take the launch signal and we'll email you once — when it ships, measured and manifested.
ChainLock Evidence is a planned FiveM evidence script for roleplay servers that need evidence collection, chain-of-custody records, case linkage, and audit history. It is designed to support police, investigation, EMS, and court RP by keeping evidence connected to the story. It is in development and not yet purchasable.
The problem it exists to solve
Evidence systems fail in the one moment they exist for: the argument about what happened. If an item's history can be edited, or lives only in the officer's memory of collecting it, then the evidence proves nothing and the scene collapses into two players asserting different pasts at each other. Chain of custody isn't a feature of an evidence script — it is the entire product.
Why we're building it
We already argue publicly that a ledger which can't survive a crash isn't a ledger (see /guides/stress-test-fivem-economy-scripts). Evidence is the same problem wearing different clothes: an append-only record whose value is precisely that nobody can quietly change it. We would rather build that correctly than ship a nice-looking item list.
What it's designed to do
- Designed as an append-only chain: collected, moved, tested, presented — each step added, none overwritten.
- Designed to share the record with the MDT rather than keeping a private table nobody else can read.
- Designed so that who touched an item, and when, is a question with an answer.
- Designed to be server-authoritative end to end — a client that can forge an evidence event can forge an alibi.
What we have not proven
How to judge any product in this category — ours included
- Ask whether an evidence entry can be edited or deleted, and by whom. If admins can silently rewrite it, the chain is decorative.
- Ask what the MDT sees. An evidence system that shares nothing forces officers to narrate the record out loud, which is the failure it was bought to fix.
- Ask how it validates net events — evidence writes are a client-reachable endpoint (see /guides/fivem-server-security-net-events).
- In our July 2026 survey we recorded exactly one evidence price, $24.99. One observation is an anecdote, not a market rate — check current prices yourself (see /guides/fivem-script-prices).
Frequently asked
Can I buy ChainLock Evidence now?
No — it's in active development with no release date and no measured performance. The page takes a launch-signal email and nothing else.
What does chain of custody mean in a FiveM evidence script?
That every action on an item is appended to a history rather than overwriting it, so who collected, moved, tested or presented a piece of evidence is answerable later. If entries can be silently edited, there is no chain — only a list.
Does an evidence script need to integrate with an MDT?
It needs to share a record with one, or officers end up narrating evidence to each other over voice while the database holds a different story. Ask any vendor which table or export the two systems actually share.
